Abstract
A hydraulic clutch actuator has two pistons operatively connected to a force transmitting member which abuts the clutch throw out bearing. The pistons are slidably disposed in respective cylinders which are formed in a housing and interconnected by passages also formed in the housing, whereby pressurized fluid can be delivered to the cylinders. The pistons, when pressurized, slide along their respective longitudinal axes which are parallel to each other and also parallel to and radially displaced from the axis of the clutch output shaft. Each piston has a hook portion on the end thereof, which engages the force transmission member and a flat surface formed parallel to the longitudinal axis for a portion of the piston length. The flat surface cooperates with a pin secured in the wall of the cylinder so that rotation of the piston in the cylinder is prevented.
