Abstract
In an hydraulic release mechanism for a vehicle clutch, a seal member is adapted to a transmission housing assembly to surround an extended portion of a push-rod in a fluid tight manner, and an hydraulic cylinder includes a cylinder housing provided at its closed end with a port for connection to a source of hydraulic pressure and being detachably secured to the housing assembly at its open end to contain one end of the push-rod therein, and a piston axially slidable within the cylinder housing through an annular seal member to subdivide the interior of the cylinder housing into a pneumatic chamber in open communication with the atmospheric air and an hydraulic chamber in open communication with the port, the piston being engaged with the one end of push-rod to urge the push-rod toward a release member of the vehicle clutch.
