Abstract

The hydraulic temperature compensator has at least one longitudinally extensible hydraulic chamber and a gas-filled chamber which is at least partly enclosed by the hydraulic chamber, wherein the hydraulic chamber is subdivided into a first sub-chamber and a second sub-chamber which are hydraulically connected to each other by at least one throttle point and wherein the second sub-chamber adjoins the gas-filled chamber. The stroke transmitter has at least the hydraulic temperature compensator, a stroke actuator acting on the temperature compensator, and a further hydraulic chamber which is fluidically connected to the first sub-chamber of the hydraulic chamber of the temperature compensator, wherein the further hydraulic chamber is in fluidic connection with a displaceably mounted actuating element.
