<p>1,093,450. Friction clutches. TWIN DISC CLUTCH CO. May 28, 1965 [June 2, 1964], No. 22660/65. Heading F2C. A friction clutch C is actuated by centrifugally induced pressure in an apply chamber CA and a retract chamber CR formed by a stepped axially movable cylinder 20 co-operating with a stepped piston 21 fast on an output shaft 4. The liquid in the retract chamber CR is varied by an adjustable scoop tube T in order to vary the clutch engaging pressure. Both chambers are supplied by liquid through a port 24 and passages in the output shaft at a relatively low pressure sufficient to lightly engage the clutch.</p> |
