Abstract
An internal combustion engine includes a rigid wall having a curved surface which forms part of the combustion chamber. The remaining part of the combustion chamber is formed by a flexible curtain whose outer edge is attached and sealed to the rigid wall. The wall and the curtain together form a closed space whose geometry and volume depend on their relative position. When the curtain moves toward the wall, the two approaching surfaces displace gas toward the center of the combustion chamber, thereby compressing it or expelling it from the chamber.
Claims16
An internal combustion engine, comprising:
- A. a rigid, curved wall;
- B. a flexible curtain including a central base portion, sealingly attached along an edge region to said rigid wall and capable of substantially conforming to the surface contours of said rigid wall, thereby defining a combustion chamber of variable geometrical form and volume;
- C. valve means, located in said rigid wall, for selective passage of gases to and from said combustion chamber;
- and
- D. heat transfer means for cooling said rigid wall and said flexible curtain.
