FRICTIONAL CLUTCH

摘要

The invention relates to an apparatus for controlling the fluid pressure in an operating space or cylinder (11) of a vehicle clutch. …A control valve (18) controls the fluid supply to said operating space dependent on the input speed of rotation of the clutch because the valve body (18) is subjected to centrifugal forces. On the other hand the valve body is loaded by the fluid pressure in the operating space (11) to make the fluid pressure in the operating space (11) dependent on the input speed of rotation.
