Japanese Patent JP2616085
Kind Code:
B2
Abstract:
A system for controlling a fluid pressure includes a pressure modulating cylinder unit having a piston and a cylinder housing defining first and second fluid chambers separated by the piston, a cutoff valve unit for isolating the first and second chambers from a pressure source and from each other, and a motor unit for pushing and pulling the piston to vary the fluid pressure in the first chamber. When the system is used for controlling a brake fluid pressure of a vehicle, the first chamber is connected with a wheel cylinder, and the valve unit is arranged to isolate the wheel cylinder and the first and second chambers from a master cylinder.
