CHECK-VALVE: Are valves that allow the flow of a fluid in one direction only.
CAM: Is a metal device with a special form which while rotating move a pin back and forth.
CHAIN: Is a metal chain like in the bicycles which connect the motor shaft to the cam valve train and is properly adjusted to coordinate the cam revolutions.
FLEXIBLE PIN: Is a pin which is flexible longitudinally using a spring in one portion of their section.
INTERNAL-CHECK-VALVE: Is a check-valve inside and totally embedded in the block of the motor.
BLINDS-TYPE CHECK-OUT-VALVE: Is a check-valve which control the flow of a fluid in one direction by opening and closing metal blinds, similar to the one used in windows.
Item.—234 They are cooling fins to dissipate the heat produced by the combustion in the cylinders 7.
Item.—235 Is a passage belonging to the internal check-valve 241 going from the low-pressure chamber 50 to the high-pressure chamber 13.
Item.—236 It is a simple longitudinally flexible metal pin driven by the cam 238, which produce the opening and closing of the blinds-type check-out valve mechanism 12.
Item.—237 It is a spring which make the pin 236 in the cam mechanism 242 to go up.
item.—238 It is the cam which push down the ping 236, making it to control the opening and closing of the exit windows blinds-type check-out valve mechanism 12.
Item.—239 Indicate a small spring located in the hinge of the gate 240, belonging to the internal check-valve mechanism 241.
Item.—240 Represent the gate who control the flow from the Low-pressure chamber 50 to high-pressure chamber 13.
Item.—241 Is the internal-check-valve mechanism built and totally embedded in the block 6 of the motor, between the low-pressure chamber 50 and the high pressure chamber 13.
Item.—242 This is the cam mechanism which control the check-out-valve 12 through the longitudinal flexible pin 236
Item.—243 It is a metal pin driven by the solenoid 9, which produce the opening and closing of the check-in-valve mechanism 11.
In this figure, the third embodiment is shown with the vane torquing device 15 underneath of the cylinders 7, the solenoid 9 for the check-in-valve mechanism 11 is located in one side of the motor, specifically beside the cylinders 7 and in the other side instead of the solenoid 10 a cam mechanisms 242 has been introduced.
Embedded in the block 6 of the motor, above and beside the drum 100 an internal-check-valve mechanism 241 has been included.
On the sides of the motor just beside the cylinders 7 the cooling passages 5 has been substituted by metal cooling fins 234.
In this figure it is presented, a frontal section of the longitudinal flexible pin in the portion in which it becomes flexible and it show the strong spring 237 around.
This is just a cross-cut section of the longitudinal flexible metal pin 236 on the portion the spring is located.
The third embodiment represents better design specially for the use in trucks, buses and heavy equipment, the torquing device 15 has been located underneath the cylinder 7 which is a much better position to receive the hydraulic oil pressure generated by the piston 4.
The solenoid 9 is located on one side of the cylinder 7 and actuate with a mechanism similar to blinds. The force required for the actioning of the blinds or any other type of mechanism used for the check-in-valve 11 is very little, therefore a solenoid is well suitable.
The solenoid 10 in the original embodiment has been substituted by a cam mechanism 242, as the blinds-type check-out-valve 12 require a tremendous force to maintain itself closed when the high-pressure air and fuel or a premix air-fuel is introduced in the combustion chamber 3 before combustion. A cam mechanism as actuator is therefore more suitable.
A longitudinal flexible metal pin 236 being actuated by the cam 238 is introduced as vital an essential item, as the continuous explosions in the combustion chamber 3 can directly affect the blinds-type check-out valve 12 as well as the cam mechanism 242, the well adjusted flexibility of the pin 236 can alleviate and lessen the effects of the sudden pressure continuously generated.
Embedded In the block 6 and on top of the torquing drum 100, an internal-check-valve 241 has been introduced which will allow hydraulic oil to flow from the low-pressure chamber 50 to the high-pressure chamber 13, this type of internal-check-valve have a spring 239 in the hinge of the gate 240, to maintain the gate closed and to allow opening the gate only with some small calculated pressure, as it is important to note that some pressure is always required in the low-pressure chamber 50 as the piston 4 must move back to TCD position
This internal-check-valve 241 may not be needed in stationary generators or in industrial premises where engines run on a continuous load like compressors, mills or pumps.
This internal-check-valve 241 may be needed in trucks or vehicles going downhill while gear box engaged, or having inertia before going to a corner stop while gearbox engaged, or in any situation in which the shaft 19 can turn faster producing more pressure in the low-pressure chamber 50 than in the high-pressure chamber 13.
If the internal-check-valve 241 is not included then the vehicle may suffer several continuous small breaks, or sudden stop of the vehicle. In this situation the diaphragms 14 or 110 my not help.
This internal-check-valve 241 may be needed also in all type of heavy equipment which engages in rapid movements from one side to the other, creating a lot of vehicle inertia.
The cooling passages 5 beside the cylinders 7 have been eliminated and substitute by cooling fins 234, as this type of engine do not produce the huge pressure during combustion unlike the regular diesel or gasoline engines, therefore, the temperature on the side of the cylinders 7 is considerable much lower, however the cooling passages 5 on top of the combustion chamber 3 have been kept.
The operation in this third embodiment is very similar to the first and original embodiment with the only difference that the blinds-type check-out-valve 12 is operated by a cam mechanisms 242 and that this cam 238 is connected to the engine shaft 19 by a chain which properly adjusted control its revolutions.
The main advantage of the third embodiment is in their design, which will be more suitable under the hood in trucks, heavy equipment and in any type of large and medium size vehicles.
Concerning the internal-check-out valve 241 and the longitudinal flexible metal pin 236, they are essentials and will contribute to make the engine ride more adaptable and smooth, and the motor more durable.
