Title: Pressurized fluid supplying arrangement particularly a master cylinder of a clutch
IPC: F16D25/12
Filed: 1982-05-20
Abstract: An arrangement for supplying pressurized fluid into a user circuit, particularly a master cylinder of a clutch, includes a cylinder housing defining a bore. A cylinder sleeve is slidably accommodated in the bore and bounds an external feeding compartment with the housing, as well as an internal pressure chamber. A piston is received in the pressure chamber for displacement in the axial direction of the arrangement in response to the application of an external force, especially that of a clutch pedal, thereto, to exert pressure on the fluid present in the pressure chamber. The sleeve has a connecting port at its end remote from the point of application of the external force, and the housing has an auxiliary port communicating with an auxiliary reservoir and a supply port which communicates with the user circuit. In an inactive position of the sleeve which is assumed when the piston is not subjected to any external force, the connecting and supplying ports communicate with the feeding compartment, and the auxiliary port is in permanent communication with the feeding compartment. Upon application of the external force, the sleeve is displaced into its active position in which a valve device containing a valve element carried by the sleeve and a valve seat provided on the housing and surrounding the connecting and supplying ports, respectively, interrupts communication between such ports and the feeding compartment, while communication of such ports with one another is maintained.
