Document Type and Number:
Japanese Patent JPS63291755
Kind Code:
A
Abstract:
PURPOSE:To make it possible to quickly raise the wheel cylinder pressure by means of a pressure pump in a device in which the released hydraulic circuit arranged in parallel with a main line is provided with the pressure pump by equipping a control valve capable of communicating and cutting-off both sides of the pressure pump. CONSTITUTION:In the middle of a main line 5 communicating a tandem master cylinder 3 and brake device 4 is a directional control valve 6 capable of being switched according to commands from a discriminant device provided. A release circuit 7 is arranged in parallel with the main line 5 from the directional control valve 6 to the brake device 4. And a return line 8 for bypassing the line to the valve 6 is also arranged so as to directly communicate the master cylinder 3 and brake device 4. The release circuit 7 is provided with a low pressure reservoir 12 and a pressure pump 13 for pressuring the working fluid from the reservoir 12 and supplying it to the brake device 4. A sub-line 17 is arranged so as to bypass the line to the pump 13, and in the middle of the sub-line 17 is an electromagnetic control valve 18 to be switched to a cutoff position according to the loading command from the discriminant device.
