Title: Improvements relating to hydraulic actuating mechanism for clutches
Inventor: SADLER FRANCIS ANTONY DAWSON
IPC: F16D48/02
Filed: 1953-11-04
Abstract: 753,516. Operating clutches. GIRLING, Ltd. Nov. 3, 1954 [Nov. 4, 1953], No. 30441/53. Class 80(2) In hydraulic clutch-disengaging mechanism comprising a pedal-operated master cylinder connected to a slave cylinder via a one-way ball valve with a restricted bypass, the ball 35 is an easy sliding fit in the stepped bore 31 of a housing 30, the smaller end of the bore being connected to the master cylinder through an axial. passage 33 in a screwed plug 32 and the larger end of the bore being connected to the slave cylinder through an axial passage in a plug 37. The restricted by-pass is along the screw-threads of the plug 32 into a transverse passage 36 leading to the passage 33. The arrangement is such that on depressing the pedal to disengage the clutch, the ball moves into the larger part of the bore, allowing free passage of fluid. On release of the pedal, the ball is moved back into the smaller part of the bore, by a spring-loaded spider 38 normally seating against the shoulder in the bore, and seats against the plug 32 just as the clutch begins to engage. Thereafter fluid can pass only through the restricted by-pass, so retarding the final clutch-engaging movement. Alternatively, the by-pass may comprise a small passage directly connecting the passage 33 to the bore 31.
