The object of invention in the related prior case of rotary engine is emphasizing in solving the linking problem between the steam wheel/flywheel and slide block that can automatically adjust the variation created by the expansion on heating and contraction on cooling then the eliminate the obstacle and bottle neck. There are no studies and researches for the engine power. The prior case should belong to the heavy type of engine similar to the jet engine. The main exserted power is produced during the period of increasing pressure. It is applied to continuous and non-interrupted combustion to create thrust force that is larger and continuous. The speed is slow, the torque is large, and the fuel consumption is higher. If based on the traditional method, the intermittent combustion utilizes the high-pressured gas. The gas is quickly expanding after instantaneous explosion then creating the thrust force. The pressure-down stroke is applied to create the thrust force. Although the torque is smaller, the response speed is faster and more practical. It belongs to the light type of engine.
The concept of present invention is based on the main structure and theory of the traditional reciprocating engine. The traditional cylinder is similar to the slide block in the prior case that is not moved in fixed space, and both pistons are also movable types. The different point is that the gas after the explosion in the traditional cylinder can expand in space and the exhausted gas can be driven out completely, but the other expansion of gas is limited to fixed space thus the driven-out of gas is not complete. The high-pressured exhausted gas has high density and is slow in responding speed, and it will offset and buffer the action force such that the explosive force is affected. In order to retrieve this defect, it is provided that the front is a propelling chamber and the rear is an outlet in the present invention beside a combustion chamber. The top of the front and rear two spaces are both set with a protruding rim to block up an inlet such that the space is reserved for gas expansion and propelling in the front while exploding, and for driving out the exhausted gas of explosion chamber in the rear. The outlet has to always keep opened with outside. The outer side of a steam wheel/flywheel is supported by screws and set with more than one slide blocks, and is set with an explosion chamber inside. While rotating, an exploding space is provided for the high-pressured gas of combustion chamber, and the high-pressured gas is guided into the propelling chamber to create the thrust force. The combustion chamber can also create the thrust force then the exhausted gas is driven out from the outlet. The above is called a cycle. Per rotation of the steam wheel/flywheel can also be designed to be multiple cycles. The aforementioned combustion chamber has no limitation in shapes, and it is better to have wide and shallow opening generally such that there are fast expansion, response, escape, and speed of high-pressured gas, and the created pressure differential can be large thus the large thrust force. But, it should be worked in a closed chamber while exploding. As for the traditional engine, the advanced sparking time is limited within the five degree space out of 360 degrees. However, the advanced sparking time of present invention can be arbitrarily adjusted without limitation. It is foreseen to obtain higher pressure before explosion. Besides, the heat contained in the exhausted gas can be recycled through the heat exchanger for warming usage while inletting. Furthermore, the temperature of cooling water can be slightly raised to become steam and turn into the kinetic energy of engine. The above are the following prospects of present invention. The second part of present invention is to use an inward-concaved inclination angle and screws to replace the roller in the prior case for better precision support of the slide blocks and capable of fine-regulation. The third part of present invention is surrounded and set with airtight devices on three sides of the rim in the jointing face between steam wheel/flywheel and slide block except the exhausted gas end.
The rotary engine must achieve to be a light type and thus be more practical. But, in the prior case, it needs further to overcome a closed pocket theory before achieving. Therefore, the object of present invention is to eliminate the defect of mutual neutralization in action force and reaction force while exploding. It has already been found out in the experiment that the explosion sound is large but there is no thrust force. The solution is to guide the airflow in the reverse direction then turn them to the forward direction, and eliminate the pressure of exhausted gas to raise the pressure differential. Furthermore, the combustion chamber can be moving type and the length of advanced igniting time can be adjusted such that the pressure is strengthened to create the maximum explosion force. The present invention. adopts. an intermittent type of operation according to the traditional engine's method. There are more than one combustion chambers designated on the steam wheel/flywheel. During operation, the. inletting, sparking, exploding, and exhausting separately proceed at different fixed positions. The gas flow is guided in a propelling chamber from an explosion chamber while exploding, and the combustion chamber creates the thrust force at the same time. The gas flow should be guided toward to the front after exploding, that is, the rotating direction of steam wheel/flywheel body, and it can have the thrust force. While it is guided toward to the rear, it is limited to be driven out into the atmosphere. It should avoid touching the steam wheel/flywheel body, otherwise the thrust force will be mutually neutralized. The outlet in the rear is used for eliminating the exhausted gas, and its space has to always keep opened with outside. The gas pumping-out and exhausting facilities can be added while it is necessary to increase the exhausting effect. Beside the aforementioned combustion chamber, the top of propelling chamber and outlet are all set with protruding faces to block the inlet to prevent the entering of mixing gas. The protruding face at said site can also be designed as curve-bending seal to increase the air-tightness. The best configuration of the present invention is to construct a cycle, that is, exploding once by at least three strokes. Per rotation of steam wheel/flywheel can be designed to be one time explosion. Depending on the requirement, it can also be a multiple times explosion. The second part of the present invention is to use an inward-concaved inclination angle and screws to replace the roller in the prior case for better precision, wear resistance and with ease of fine-regulation the no-gap error. While exploding, the action force pushes the steam wheel/flywheel to rotate along the clockwise direction and the reaction force pushes the slide block rotate along the counter clockwise direction. Besides the resistance of screws, it also sustains simultaneously at side face a partial force supporting the tight fit between the slide block and steam wheel/flywheel. Further, since the displacement of supporting point in the slide block relative to screws caused by the expansion on heating and contraction on cooling is very minor, the outward protruded circular sliding path is replaced by more than two inclination angles with inward concaved outer rims. The volume of slide block can thus be reduced. The aforementioned inclination angle and the steam wheel/flywheel construct an inclined angle, the pressure between the slide block and steam wheel/flywheel is expected to approach to zero for the reduction in the friction resisting force and power loss. The magnitude of pressure in between is inverse proportional to the said inclined angle. The degree of slant in the inclination angle largely affects the output engine power, thus it is required to select a proper inclined angle. The third part of the present invention is to set the airtight devices on the remaining three directions of the rim except the exhausted gas end in the perimeter of jointing sites between steam wheel/flywheel and slide block. Two sides are set with circular layers and pressured by springs. Another end is lodged in the concaved sites of the slide block by a circular plate and pressured by springs. The bottom part close to inner side of circular plate is set with inclination face to raise the airtight effect at the said site. Theoretically, the steam wheel/flywheel and slide block should be tightly fit by the concentric circles. In reality, the aforementioned disposal is necessary since there will be deformation after expansion on heating and contraction on cooling.
It is to be understood that the engine structure according to the present invention is to exclude the compression stroke in the four strokes of traditional engine. Therefore, the fuel, mixing gas, high-pressured air, and so on are all required to be supplied by outside. Please refer to
