Hydraulic mechanism e.g. for clutch, has take up cylinder and master cylinder, with fluid connecting line hydraulically connected between them with screen body having central shaft for pressure reduction

摘要

The mechanism has a take up cylinder and a master cylinder, with a fluid connecting line hydraulically connected between them. The mechanism has a screen body (2) with a central shaft (5) for pressure reduction and a spring (10) shaped guard ring loaded by pressure (8). At the base of the central shaft (11) a radial pitch circle opening (11) is arranged and the body and or the central shaft has a predetermined decrease of pressure when coupling the clutch during excess of a pre-determined volume stream of the inserted fluid. The body is movable when disengaging the fluid stream against a first block (7) of the housing (1) without pressure reduction. The body is movable when coupling against a spring-tensioned guard ring that an aperture is removed when a pre-determined volume stream is present.
