Compact master cylinder with integral reservoir connected to hollow piston stem

An actuator for a fluid pressure system includes a foot pedal (50) pivotally connected to a support structure (51) for movement away from and into a rest position. A piston-cylinder assembly (2) has a piston (9) slidably mounted within a bore (8) of a cylinder member (3) and a pressure chamber (14)...

Beschreibung
Zusammenfassung:	An actuator for a fluid pressure system includes a foot pedal (50) pivotally connected to a support structure (51) for movement away from and into a rest position. A piston-cylinder assembly (2) has a piston (9) slidably mounted within a bore (8) of a cylinder member (3) and a pressure chamber (14) formed at least in part within said member. Movement of said piston in one direction relative to said member is operable to cause a reduction in the volumetric size of said chamber. The assembly (2) is pivotally connected to the foot pedal and the support structure respectively, and the pivotal connection to the foot pedal is located intermediate the ends of a lever forming part of the foot pedal. The two pivotable connections with the support structure are spaced apart so that movement of said pedal away from said rest position causes movement of said piston in the one direction.
