Abstract

PURPOSE: To surely open or close a valve, by attaching a mass to a leaf spring to add the centrifugal force of the mass to the valve opening force of the spring.
CONSTITUTION: A leak port 12 is provided through the leaf spring 13 inside an annular projection 7a which is provided on a clutch piston 7 so that the projection comes into contact with a friction member 6. The leaf spring 13 extends in a radial direction on a hydraulic working chamber 9. The mass 15 is attached to the outer end of the leaf spring corresponding to a recess 7b provided on the annular projection 7a. When the clutch is rotating, the leaf spring not only has its own valve opening force Fe but also suffers the centrifugal valve opening force Fm of the mass. The valve opening force Ff of working oil is set as Ff≈Fm. When Ff is higher than Fe, the valve is immediately opened. When hydraulic pressure has vanished, all the valve opening force is Fe+Fm and the leak port 12 is immediately opened. Therefore, the operation of the valve is sure.
