- while said valves of said expansion chamber are exclusively closed by respective thrust means of said control device and said valves of said expansion chamber open by pressure in gases only at times when said thrust means remove their closing thrusts onto the respective valves.
- 3. The engine of claim 1,
- wherein said control device provides at least one control chamber with entrance and exit control ports for the inlet and outlet of a control fluid.
- 4. The engine of claim 3,
- wherein said control chamber is provided with an entrance seal,
- wherein said stem and thereby said extension of said inlet valve of said expansion chamber extends through said entrance seal into said control chamber,

- wherein said faces are formed on opposite ends of a piston which forms said head, and,
- wherein said control chamber has control fluid inlet and outlet ports on opposite ends of said control chamber and thereby endwards of said faces, whereby fluid which alternatingly enters and exits through said inlets and outlets of said control chamber presses alternatingly against said faces and thereby alternatingly provides onto said faces the force to open and close said inlet valve of said expansion chamber.
- 5. The engine of claim 3,
- wherein said control device provides a plurality of said control chambers equal in number to the number of said stems of said outlet valve of said expansion chamber,
- wherein each of said plurality of control chambers forms a seal, and,
- wherein said stems of said outlet valve of said expansion chamber individually extend through said seals into said control chamber.
- 6. The engine of claim 5,
- wherein said control chamber communicates the fluid in said control chamber to the ends of said stems, and,
- wherein said control chamber is communicated to a control valve which alternatingly connects said control chamber to a fluid under pressure and to a space of no pressure to alternatingly pass fluid into and out of said control chamber to alternatingly press against and free the ends of said stems.
- 7. The engine of claim 1,
- wherein a rotary collection member extends with it's axis substantially vertically from the top into a combustion chamber, has radial passages for the collection of said pure gas into said puregas passage,
- wherein said rotary collection member is rotatable borne in a respective vertical bearing and provided with drive means to provide a rotation to said rotary member and provided with radial exit bores to transfer said pure gas into said power gas transfer passage, and
- wherein said radial passages are provided above said blades in order that said blades supply radial centrifugal force to unpure fuel particles to move them away from said rotary collection member before said unpure particles would reach said radial passages to collect said gas.
- 8. The engine of claim 1,
- wherein said combustion chamber burns a fuel in air under a given pressure with said pressure extending into said compression and expansion chambers, and,
- wherein said expansion chamber has a larger cross-sectional area than said compression chamber and a larger expansion volume than said compression volume of said compression chamber.
- 9. The engine of claim 1,
- wherein said pump means of said fuel supply means is provided with means to supply intermittently in periodic timed thrusts respectively dimensioned quantities of fuel portions into said combustion chamber in timed relation to said openings and closings of said respective compression discharge valves of said valves.
- 10. The engine of claim 1,
- wherein control valve means are provided to control the inlets, outlets and passages of said expansion chambers in a proper relation to provide, that at constant pressure combustion in said combustion chamber the delivery volume of said compression chamber to said combustion chamber remains considerably less than the expansion volume of said expansion chamber taken from said combustion chamber,
- whereby said expansion chamber provides a higher power than said compression chamber consumes at a respective cycle and time.
- 11. A combustion engine, comprising, in combination,
- a compression chamber having inlet means, a combustion chamber provided with with fuel supply means and ignition means, an expansion chamber with inlet and outlet means, at least one passage from said compression chamber to said combustion chamber and from said combustion chamber to said expansion chamber, movable members in said compression and expansion chambers which expand and reduce the volumes of said chambers in periodic cycles, said expansion chamber provided with at least two valves with said two valves having extensions which individually extend outwards from said valves through a respective chamber head wherein they are guided, said valves controlled by respective control devices in suitable times relation respective to the respective expansion and exhaust of said expansion chamber and thereby in relation to the movements and positions of said moveable member in said expansion chamber, said inlet means of said compression chamber provided by an inlet valve and said compression chamber provided with an outlet valve between said compression chamber and said passage from said compression chamber to said combustion chamber,

- wherein said pure gas passage is a medial bore in said collection member with said pure gas passage communicated to radial bores which extend from said pure gas passage to said combustion chamber, while the end of said pure gas passage extends into said passage from said combustion chamber to said expansion chamber,
- whereby the centrifugal forces which act in said radial bores during the rotation of said collection member prevent the entering of unpure particles, which are heavier than the pure gas, into said pure gas passage.
- 12. The engine of claim 11,
- wherein said rotary collection member extends with its axis substantially vertically from the top of said combustion chamber into said combustion chamber with said puregas passage closed by the bottom of said collection member,
