First Claim
1. A hydraulic braking device comprising:
- a housing;
a pump disposed in the housing;
a motor for driving the pump;
a plurality of solenoid valves disposed in the housing;
a wheel cylinder port provided in the housing and connected to a wheel cylinder; and
a flow channel provided in the housing to connect the pump, the plurality of solenoid valves, and the wheel cylinder port,the motor and the plurality of solenoid valves being controlled to generate fluid pressure in the wheel cylinder,the hydraulic braking device comprising;

Abstract
The present invention pertains to a hydraulic braking device which is provided with: a housing; a pump disposed within the housing; a motor that drives the pump; a plurality of solenoid valves disposed within the housing; WC ports that are provided to the housing and connected to wheel cylinders; and flow channels provided within the housing to connect between the pump, the solenoid valves and the WC ports, and in which the motor and the solenoid valves are controlled such that fluid pressure is generated in the wheel cylinders. The hydraulic braking device is further provided with a Helmholtz damper that is disposed within the housing to be connected to the flow channels and reduces pulses generated by the driving of the pump.
