A compensating arrangement for a variable compression ratio engine, the compensating arrangement comprising a piston (1) reciprocally movable in a guiding sleeve (2) having an open end (24) in communication with a combustion cylinder of the engine and a closed end (11, 30), wherein the arrangement further comprises a first pneumatic cushion (20) formed between the closed end (11, 30) of the guiding sleeve (2) and the internal surface of the piston (1) such as to limit the movement of the piston (1) towards the closed end (11, 30) of the guiding sleeve (2), a second pneumatic cushion (19) formed between the guiding sleeve (2) and the external surface of the piston (1) such as to limit the movement of the piston (1) towards the open end (24) of the guiding sleeve (2), and a check valve (18) configured to provide pneumatic medium to the second pneumatic cushion (19) in amount dependent on the displacement of the piston (1) during its movement towards the closed end (11, 30) of the guiding sleeve (2). |
