  • Concentrically mounted hydraulic clutch slave cylinder
    Patent number: 6389956
    Abstract: A concentric slave cylinder for use in a clutch actuator in which the housing of the slave cylinder is a two-part construction with one of the members having an injection molded polymer member. In one embodiment, both the inner and outer cylindrical members forming the annular chamber for the piston are formed as injection molded polymer members; in a second embodiment, the outer cylindrical member is formed as an injection molded polymer member and the inner cylindrical member is formed as a cold formed steel member; and in a third embodiment, the inner cylindrical member is formed as an injection molded polymer member and the outer member is formed as a cold formed steel member. The use of injection molded members reduces the cost of the housing assembly and the use of a two-part construction allows the provision of a small annular chamber for receipt of the piston.
