<p>PROBLEM TO BE SOLVED: To provide a brake fluid pressure controller for vehicle, capable of preventing brake fluid from flowing into the first reservoir when the brake fluid is stored in the second reservoir. SOLUTION: This brake fluid pressure controller for vehicle consists of the first reservoir RS1 storing brake fluid delivered from a wheel cylinder through modulators PC1 to PC8, a hydraulic pump HP1 connecting its suction side to the first reservoir and connecting its delivery side to a main hydraulic passage between the modulator and a master cylinder MC, two opening/closing valves SC1, SI1 connecting or disconnecting a line between the master cylinder and the modulator and connecting or disconnecting a line between the master cylinder and the suction side of the hydraulic pump. A non-return valve CV7 is provided which prevents generation of a flow in the reverse direction by permitting the brake fluid to flow to the hydraulic pump side between a connecting point J2 connecting the master cylinder to the suction side of the hydraulic pump through the opening/closing valve SI1 and the first reservoir. An opening/closing valve SI3 and the second reservoir RS2 are connected to the suction side of the hydraulic pump and connected to the first reservoir through the non-return valve CV7.</p> |
