<P>PROBLEM TO BE SOLVED: To achieve miniaturization of the brake fluid pressure control unit for a vehicle by reducing diameter (cross section) of an intake passage provided between an atmospheric reservoir and of a pump and an exhaust passage, and by contriving reduction in a space occupied by passages and effective utilization of an empty space in a fluid pressure block in the unit. <P>SOLUTION: Pumps 10<SB POS="POST">-1</SB>, 10<SB POS="POST">-2</SB>driven by motors 11<SB POS="POST">-1</SB>. 11<SB POS="POST">-2</SB>are incorporated to each of fluid pressure systems 6<SB POS="POST">-1</SB>, 6<SB POS="POST">-2</SB>, an intake passage 7 making the pump absorb brake fluid in the atmospheric reservoir 3 by detouring a master cylinder 2, and an exhaust passage 8 returning the brake fluid exhausted from a passage leading to discharge opening of each pump through a solenoid valve SRC1, SRC2 are formed in a fluid pressure block 20 of the brake fluid pressure control unit for vehicle supplying the brake fluid to cylinders 4F<SB POS="POST">-1</SB>, 4F<SB POS="POST">-2</SB>, 4R<SB POS="POST">-1</SB>, 4R<SB POS="POST">-2</SB>of wheels belonging to respective systems from respective fluid pressure systems, at least one side of the intake passage and the exhaust passage is provided independently for each fluid pressure system. <P>COPYRIGHT: (C)2012,JPO&INPIT |
