Claims

[Claims for Utility Model Registration] (1) A push rod integrated with a rotatable link arm presses a plunger in a housing according to the relative displacement of the sprung and unsprung parts of the vehicle, and also presses the plunger in the housing when braking. In a linkage type hydraulic pressure control valve that operates the plunger to close the liquid flow path when the hydraulic pressure exceeds a predetermined value to control the brake hydraulic pressure to the brake unit to be reduced, the plunger side of the push rod when not braking. A linkage-type hydraulic control valve characterized in that a seat member is interposed between the push rod and the plunger, the seat member stopping movement at a predetermined position by locking with one end of the housing. (2) In the linkage-type hydraulic control valve according to claim (1), the first ring is provided at one end of the housing with a back-up spring for preventing removal of a cup seal for sealing between the plunger and the cylinder hole. A second ring member is provided at one end of the housing, and further, a second ring member is provided at one end of the housing, and the second ring member is locked to the member and stops moving when the sheet member facing the plunger moves to a predetermined position on the push rod side. Sufficient length so that even if the member comes off and the back-up spring moves toward the seat member, the entire back-up spring will not fall out of the cylinder hole when the seat member is locked with the second ring member. A linkage type hydraulic control valve characterized in that the back-up spring length is set to .
