Abstract

913,753. Friction clutches. BROWN INDUSTRIES Ltd., DAVID. May 16, 1961 [May 20, 1960], No. 17781/60. Class 80 (2). [Also in Group XXIX] The supply and exhaust of the pressure liquid for the actuator piston 11 of a friction clutch is controlled by a centrifugal valve 21 mounted in a radial bore 18 communicating with a radial supply passage 15 and an axial exhaust port 20, the outer end of the valve having a reduced shoulder portion 22. In the exhaust position shown centrifugal force holds the valve 21 in its outermost position in which the actuator cylinder communicates with exhaust port 20 through parallel ports 19 connecting with bore 18. Pressure liquid supplied through passage 15 forces the valve inwards and flows to the actuator cylinder past the shoulder portion of valve 21 and through ports 19, the main body portion of the valve blocking exhaust port 20. In a modification, Figs. 3 and 4 (not shown), radial movement of the valve is controlled by a separate centrifugal member acting on the valve by a two-armed lever.
