Abstract

The invention relates to the field of automobile clutches and aims to provides a clutch master cylinder which comprises a pump body, a piston, a reset spring and a push rod, wherein the reset spring is used for resetting the piston; the front end of the push rod stretches into the pump body, so as to push the piston; a pressure cavity is formed by the front end of the piston and the pump body; an annular groove is formed in a side wall of the piston; a liquid feeding cavity is formed between the annular groove and a side wall of the pump body; a liquid inlet hole communicated with the liquid feeding cavity and a liquid outlet hole communicated with the pressure cavity are formed in the pump body; a liquid passing through hole communicated with the liquid inlet hole is formed in one end of the pump body; if a clutch pedal is not trampled, the piston is in an initial position; the other end of the liquid passing through hole is communicated with the pressure cavity. When the clutch master cylinder works, the pressure of the liquid outlet hole is easy to establish, and the pressure cavity is backfilled with hydraulic oil faster.
