  • Fluid pressure actuator
    Patent number: 5090201
    Abstract: The actuator comprises a clutch pedal lever (12) which is pivotally connected to a support (17). The pedal is integral with a cylinder (18) having a piston (20) therein which is connected to a hollow pushrod (28). The pushrod is also pivotally connected to the mounting (17). Pivoting movement of the pedal (12) causes the cylinder (18) to move relative to the piston so that fluid within the cylinder will operate a slave cylinder (44). The clutch and pushrod have spaced axes of pivoting (13a, 14a) and the piston (20) is shaped to permit a degree of tilting to take place between the piston and the cylinder. The system also includes a reservoir which can communicate with the cylinder when the piston occupies a particular position in the cylinder.
