Pump Device and Braking System
First Claim
1. A pump device comprising:
- a housing including therein an oil passage and a pump;
a motor configured to drive the pump;
a motor mounting surface which is formed on one side surface of the housing, and to which the motor is mounted;
a first port which is formed on the motor mounting surface, and to which a pipe connected to a master cylinder is mounted;
a first surface formed so as to continue to the motor mounting surface, and including a second port to which a pipe connected to a wheel cylinder is mounted;
a second surface formed so as to continue to the motor mounting surface and the first surface; and
a third port which is formed on the second surface, and to which a pipe connecting an external device and the oil passage to each other is fixed.
