ABSTRACT:
A fluid actuated operator and linkage for a clutch. The linkage includes an operator link connected between the operator and a throwout bearing actuator arm. The operator includes an operator rod pivotally connected to the operator link and extending through an axial bore of a sleeve internal of the operator housing. The sleeve is connected for movement with the clutch pedal. The sleeve and operator rod form a valve for connecting a source of fluid under pressure to a pressure responsive means in the operator to generate a force to move the rod and disengage the clutch as the clutch pedal is depressed. As the clutch pedal is raised, the valve vents the fluid pressure responsive means to reduce the applied force which allows the clutch pressure springs to return the clutch to engagement. Embodiments are disclosed which have nonlinear characteristics which correspond to the force/displacement operating curves of certain types of clutches.
