Abstract

PURPOSE: To improve the steering sense of a power steering device and to secure safety of a hydraulic apparatus even if one of two pumps malfunctions by releasing the back pressure to the power steering device occurred by the operation of a brake booster at normal time.
CONSTITUTION: When a brake pedal 15 is depressed, a passage area between the inlet side 6a and the outlet side 6b of a brake booster is throttled to increase the hydraulic pressure at the inlet side 6a to thereby produce brake pressure in a master cylinder 8 so as to operate wheel cylinders 12, 13 for braking operation. The brake pressure at the inlet side 6a is also acted to a power steering device 3 to increase the exhaust pressure of a pump 16 to thereby increase the pressure in the chamber 34 of a passage control valve 20. When this pressure becomes higher than predetermined value, a poppet valve 23 is moved rightwardly to communicate between annular grooves 26 and chamber 27 to thereby release the back pressure operating the device 3.
