ABSTRACT:
Disclosed is a control for a pumping device in vehicle application in which, upon throwing a power switch (6) and closing a brake actuator switch (8), a second driver transistor (76) is rendered conductive and a first driver transistor (75) non-conductive, thereby rendering a power transistor (71) conductive. The power transistor in the conductive state enables a DC motor (2) to be supplied with a DC voltage from batteries (5). The DC motor drives a pump (1) which in turn feeds a pressure to activate a pressure-operating unit (10). A pressure detecting switch (4) detects the pressure of the pump and particularly provides a pressure detection signal when the pressure reaches a predetermined value. In response to the pressure detection signal the first driver transistor becomes non-conductive and the power transistor becomes conductive, thus supplying the DC voltage to the DC motor.
