AUTOMOBILE ABS BRAKE PUMP

摘要

In a ABS pump, an eccentric cam is installed in a casing at the front end of the shaft of an electric motor and sends the brake fluid in the reserver to the master cylinder. A penetrated hole(13) is formed in the cam operation direction of the pump casing(1), and is connected with both intake part(4) and discharging part(7). A closer(2) is mounted on an adapter(3) forming a connecting hole(12) connecting the pressure room(14) of the cylinder(11) with both intake and discharging parts(4)(7). The adapter(3) is placed on the cylinder(11) placed on the penetrated hole(13). A piston is compressed toward the eccentric cam(10) by a compression spring(9) in the pressure room(14). The intake part(4) installs an intake valve(5) having intake guide member(15) and the discharging part(7) installs a discharging valve(6) having a discharging guide member(16).
