Abstract
A hydraulic control unit of an electronically controlled hydraulic brake system has a housing () accommodating a pump () and at least one low-pressure accumulator. The low-pressure accumulator is positioned in a location at a lower height than the cam cavity () of the pump (), and a drainage bore () connects the cam cavity () with the spring chamber () of at least one of the low-pressure accumulators. This allows the drainage of brake fluid from the cam cavity () into the spring chamber () solely by way of gravity. Thus this measure eliminates the risk of damage to the pump motor in the event that ambient water penetrates the cam cavity (), which might flush brake fluid from the cam cavityinto the housing () of the pump motor.
