  • Pressure regulating dampers
    Patent number: 7124865
    Abstract: A damper includes housing bounding a chamber. A barrier is movably disposed within the chamber so as to divide at least a portion of the chamber into a pressure compartment and a control compartment each having a volume, the volume of the pressure compartment and the control compartment each being adjustable based on movement of the barrier. A first compressible gas is disposed within the pressure compartment while a first hydraulic fluid is disposed within the control compartment A piston shaft has a first end slidably disposed within the control compartment. A temperature compensator disposed within the chamber automatically adjusts the combined volume of the pressure compartment and the control compartment based on the temperature of the first hydraulic fluid within the control compartment so as to regulate the pressure within the control compartment.
