Abstract:
A variable compression ratio engine comprises a stationary engine block in which movable members interact to enable a piston to translate in a combustion cylinder of the engine block, defining a stroke of the combustion piston The engine further comprises a self-contained device for adjusting the position of the top dead center of the combustion piston, the self-contained device being connected to or built into at least one of the movable members and having a high-pressure hydraulic chamber to counteract the combustion and inertial forces at the bottom dead center, a low-pressure hydraulic chamber to counteract the inertial forces at the top dead center, at least one calibrated conduit to enable hydraulic fluid to flow between the high- and low-pressure hydraulic chambers, and return means to bring the device back to a nominal position.

Claim (Index 35):
The variable compression ratio engine according to claim  1 , wherein the mechanical return device comprises a spring.
