Title: PISTON PUMP FOR BRAKE SYSTEM OF VEHICLE
Abstract:
A piston pump comprises: a sleeve housing having a discharge hole and having a bore formed therein; a piston having an inlet flow path for introducing oil into the bore and inserted into the bore so as to reciprocate; an inlet flow valve installed so as to open and close the inlet flow path; a discharge valve cover fastened to the sleeve housing so as to surround a portion where the discharge hole is formed; a discharge valve installed to open and close the discharge hole; and a sealing member interposed between the sleeve housing and the piston to perform a sealing function. The sealing member has a release preventing protrusion that is formed so as to lock the piston, thereby preventing the piston from being released.
