油圧クラツチ用昇圧制御弁。 A bottomed cylindrical plunger that opens and closes a primary passage and a secondary passage formed in a substantially cylindrical casing.
A throttle passage is formed in the casing so as to be biased in the valve closing direction by a first spring so as to be freely displaceable, and to communicate a balance chamber formed inside the plunger with the primary passage. second to
In a pressure boost control valve for a hydraulic clutch that is provided with a piston that can be freely displaced by being biased by a spring, a cylinder portion is formed in a portion of the primary side passage of the casing that faces the tip of the plunger, and a cylinder portion is formed in this cylinder portion. A substantially cylindrical sliding part that opens towards the primary passage that is slidably fitted is formed integrally with the plunger, and a through hole that opens and closes both the passages is formed in this sliding part, A pressure boost control valve for a hydraulic clutch characterized by increasing the amount of lift of a plunger in a pressure control state.
