Abstract
PURPOSE:To secure safety in relay contact welding or the like by applying an electric current to a directional control valve for increasing or decreasing and holding braking oil pressure through the first relay contact, and connecting the second relay contact in series to the first relay contact to control the supply of an electric current to a motor-driven pump through both contacts. CONSTITUTION:In a device for increasing or decreasing and holding braking oil pressure by controlling the supply of an electric current to a directional control valve 46 interposed in a braking oil pipe, a directional control valve relay 71, a motor relay 72 and a transistor TR for controlling the directional control valve are connected to an output port 67 of an electronic control device 18. The operation of the directional control valve 46 and a motor-driven pump 50 is controlled through the contacts 71a, 72a of the respective relays 71, 72 and the transistor TR. At this time, a solenoid coil SC of the directional control valve 46 has one terminal connected to a power supply line VB through the contact 71a and the other terminal earthed through a collector emitter of the transistor TR. The motor-driven pump 50 is connected to the power supply line VB through the contact 71a in addition to the contact 71a.
