  • Reciprocating piston-internal combustion engine with variable compression ratio
    Patent number: 4602596
    Abstract: For changing the compression ratio of a reciprocating piston internal combustion engine the piston 3 consists of an outer piston part 7 and an inner piston part 10 which are connected with each other by a thread 13,14. By turning the outer piston part 7 by means of a bushing 18 which is axially fixed, but rotatable around piston axis 15 and which is in engagement with the outer piston part 7 by means of a longitudinal gear 19,20, the outer piston part 7 can be turned steplessly during operation with respect to the inner piston part 10, whereby the outer piston part 7 is displaced along the piston axis 15, thus changing the volume of the operating chamber and thereby the compression ratio.
