  • Device for temperature compensation in a pressure medium circuit
    Patent number: 4026110
    Abstract: A device for compensating temperature dependent volume variations in a closed pressure medium system where at least two variable volume members are connected via a pipe to each other for transfer of movement between each other. At least one of the movement transmitting members has two ends freely movable relative to the pipe. One of the ends cooperates with a support, the position of which varies with the temperature as the volume of a flexible means, which is rigidly attached to the pipe, changes. The other end of the movement transmitting member is freely movable relative to the flexible means.
