を止めるようにされている車両用制動液圧制御装置。[Scope of Claim for Utility Model Registration] A body having a brake mask cylinder connection port and a rear brake cylinder connection port, and one end of the body and the other end with a diameter smaller than this, which are fitted into an inner hole of the body. , a first liquid chamber having one end surface exposed in the body and communicating with the brake mask cylinder connection port, an air chamber having the other end surface exposed, and an annular valve portion between both ends thereof being exposed and the rear an annular second fluid chamber communicating with a wheel brake cylinder connection port; and communicating with the second fluid chamber through an inner hole of a first annular valve member supported by the body and cooperating with the annular valve portion; The brake mask cylinder is divided into an annular third fluid chamber communicating with the brake mask cylinder connection port, and further has a communication passage therein that is open at one end surface and communicates the first fluid chamber with the second fluid chamber. a spring that is installed in the second liquid chamber and urges the hydraulic piston toward the first liquid chamber so that the annular valve part is separated from the first annular valve member; A stepped hydraulic response sleeve is installed in the second liquid chamber and moves in a direction to increase the force of the spring due to hydraulic pressure; It occupies a rest position in contact with a stopper provided on the body and is separated from a second annular valve seat member fixed to one end of the hydraulic pressure responsive piston, and rolls when the vehicle deceleration exceeds a predetermined value. a spherical inertia-responsive valve body that contacts the second annular valve seat member and blocks communication between the communication passage and the first liquid chamber, the annular valve portion of the hydraulic pressure-responsive piston and the first fluid chamber; The area obtained by subtracting the circular area of the seal diameter between one end of the hydraulic pressure responsive piston and the body from the circular area of the seal diameter with the annular valve seat member is the area of the seal between the other end of the hydraulic pressure responsive piston and the body. The set load of the spring is set to be larger than the circular area of the diameter, and the set load of the spring is set to move the hydraulically responsive piston to its rest position or in the vicinity thereof in a state where the vehicle deceleration of the predetermined value occurs under a first predetermined hydraulic pressure when the load is light. The hydraulic pressure-responsive piston is set to slide at a lower pressure than a second predetermined hydraulic pressure that is maintained and causes the vehicle deceleration of the predetermined value at the time of constant volume, and the hydraulic pressure is set to When a third predetermined hydraulic pressure higher than the predetermined hydraulic pressure is exceeded, the hydraulic pressure-responsive sleeve starts to move and the force of the spring is increased in accordance with the hydraulic pressure, so that the hydraulic pressure becomes higher than the third predetermined hydraulic pressure. When the fourth predetermined high hydraulic pressure is reached, the hydraulic pressure response switch IJ
- A braking hydraulic pressure control device for a vehicle, wherein a brake member contacts the body to stop the force of the spring from increasing.
