Claims

[Scope of utility model registration request]

(1) A piston that moves according to the liquid pressure sealed in the liquid seal chamber by an inertia valve adjusts the compression amount of the spring that presses the valve plunger of the pressure reducing valve mechanism in the valve opening direction, and controls the corner liquid pressure. In the deceleration sensing type hydraulic pressure control valve, an air sealing chamber is installed in the liquid sealing chamber to retain a certain amount of air, and this air is compressed at the initial stage of braking.
A deceleration sensing type hydraulic pressure control valve characterized in that a liquid flow is generated in an orifice section interposed in a passage upstream of a liquid seal chamber.

(2) The deceleration sensing type hydraulic control valve according to claim (1), wherein the air filling chamber is formed by inserting an elastic hollow tube.

(3) The deceleration sensing type hydraulic pressure control valve according to claim 1, wherein the air sealing chamber is formed by inserting an elastic ring having closed cells.

(4) The deceleration-sensing hydraulic pressure control valve according to claim 1, wherein the air sealing chamber is formed by providing an air pocket in the liquid sealing chamber from which air cannot be vented. .
