<p>PURPOSE: A pump housing for an ABS(Anti-lock Brake System) is provided to reduce time and cost without forming a separate passage, to reduce the total volume of the pump housing with keeping volume same with an existing accumulator receiving unit, and accordingly to improve productivity and supply small-sized and lightweight products. CONSTITUTION: A pump housing(100) for an ABS is composed of a motor receiving unit(10), pump receiving units(20), inlet solenoid valve receiving units(40), outlet solenoid valve receiving units, and an accumulator receiving unit. The accumulator receiving unit comprises first chambers(30a), second chambers(30b) formed at the upper end of the first chamber with having a diameter smaller than the first chamber, first communicating ports(21) for communicating the first chamber with the pump receiving unit, and second communicating ports(71) for communicating the second chamber with the outlet solenoid valve receiving unit formed at the rear end of the pump housing.</p> |
