ABSTRACT:
The present invention relates to an ABS pump housing. The ABS pump housing includes: a motor-receiving unit, a pump-receiving unit, an entrance solenoid valve, an exit solenoid valve and an accumulator-receiving unit, wherein the accumulator-receiving unit comprises: a first chamber, a second chamber arranged above the first chamber and having a diameter smaller than that of the first chamber, a first communication port for communicating the first chamber with the pump-receiving unit and a second communication port for communicating the second chamber with an exit solenoid valve-receiving unit in a rear end of the pump housing. A flow path of the first communication port communicating with the pump-receiving unit is readily formed in a large size. The second chamber is formed to communicate with the exit solenoid valve in the exit side so that any additional communication port is not necessary, by which the pump housing is downsized and light-weighted.
