Abstract
In a fluid pressure control valve unit, a pair of first and second partition members are assembled within a housing to subdivide the interior of the housing into first and second chambers and to provide a space between the partition members. The first chamber is in open communication with an outlet port for connection to rear wheel brake cylinders, and the second chamber is in open communication with an inlet port for connection to a master cylinder. Assembled within the first chamber are a stepped piston and a control valve assembly cooperable with the piston. The piston extends through the first partition member into the space, and a control plunger is slidably disposed within an axial bore of the second partition member to provide a third chamber opening toward the second chamber. An inertia-control valve assembly is disposed within the second chamber to control the pressure in the third chamber in accordance with the rate of deceleration. In such arrangement, one of the partition members is provided at its peripheral portion with a fluid communication passage between the first and second chambers.
