感知型液圧制御弁。[Scope of Claim for Utility Model Registration] A housing having an inlet port connected to a master cylinder and an outlet port connected to a wheel cylinder, and a plunger housed in the housing, are arranged so that the pressure between the hydraulic pressure of the inlet port and the hydraulic pressure of the outlet port is A proportioning valve that responds to the difference by reducing the fluid pressure at the inlet port at a fixed ratio to create the fluid pressure at the outlet port, a sleeve housed in the housing, a communication hole formed in the housing, and a connecting hole between the housing and the sleeve. A ball chamber is defined in communication with the inlet port through a gap defined between the two and a communication hole formed in the sleeve, and a ball accommodated in the ball chamber and responsive to deceleration of the vehicle is disposed within the housing. A deceleration sensing valve communicates or isolates the defined containment chamber and the ball chamber to confine liquid pressure within the containment chamber, and a transmission piston transmits the reduced pressure confined within the containment chamber to the plunger of the proportioning valve. A deceleration sensing type hydraulic pressure control valve comprising the following: A deceleration sensing type hydraulic pressure control valve comprising: a sleeve of the deceleration sensing valve is provided with a convex portion projecting into the gap.
