Claims

[Scope of utility model registration request]

A sleeve 15 is slidably fitted into the center of a cylinder hole 14 provided in a valve case 13, and a balance piston 7 is provided with poppet valves 31, 32 which are outwardly pressed at both ends by conical springs 29, 30. The small diameter portions of plungers 41 and 42 are arranged to be slidably fitted in the cylinder hole 14 and have large, medium and small diameter portions from the outside to the inside, and the small diameter portions of the plungers 41 and 42 are slidably fitted into the sleeve 15 and have large diameter portions. portion is slidably fitted into the cylinder hole 14, and the plunger 41.
The inner ends of balance piston springs 43 and 44 arranged so as to surround the middle diameter part of 42 are brought into contact with the sleeve 15, and the outer ends are brought into contact with the large diameter part of the plungers 41 and 42, so that the plungers 41 and 42 are moved. Valve seats 53 and 54 are provided at the inner ends of the penetrating through holes 51 and 52 to repeatedly connect and disconnect with the poppet valves 31 and 32 during proportional depressurization, thereby forming chambers 57 and 58 between the balance piston 7 and the plungers 41 and 42. It is a part of the input chamber 55 and the plunger 41.
A brake hydraulic pressure control valve device in which a chamber 59.60 between 42 and the end face of a cylinder hole is a part of an output chamber 61.62.
