Abstract
A small, lightweight, easy-to-assemble brake pressure controller manufactured by integrating a hydraulic circuit block including pumps and pressure regulating solenoid valves, pump-driving motor, and a control block having a built-in electronic control circuit for producing signals for actuating the motor and the solenoid valves. The rotor of the motor is housed in a bore formed in the hydraulic circuit block in which are mounted the plunger pumps and solenoid valves. A rear opening of the motor is closed by the control block. Lead pins extending from a brush holder of the motor and solenoid coils of the solenoid valves extend through a case of the control block, and are electrically connected to an electronic control circuit on a printed circuit board. With this arrangement, it is possible to electrically connect the hydraulic circuit block to the control block without using external lead wires and connectors. The feeding brush and the solenoid coils can be assembled easily by mounting them integrally on the control block beforehand.
