A reciprocating piston is disclosed with variable compression height for internal combustion engines in particular. For structural simplification of the temperature-dependent change in the compression height of the reciprocating piston, a spring is provided which consists of a shape memory alloy and interacts with the pressure limiting valve. This permits temperature-dependent change in the compression height of the reciprocating piston exclusively by the pressure limiting valve so that structural simplification is achieved. |
