したことを特徴とする温度補償付流量制御弁。[Claims for Utility Model Registration] A spool is slidably provided in the sliding hole of a body in which a sliding hole is formed between an oil inlet and an oil outlet, and the spool and the oil inlet or outlet A flow control valve having an orifice for flow control formed between the spool and the spool, wherein a nozzle is integrally provided at one end of the spool, and
A control oil chamber from which the nozzle protrudes is formed in the body, a flapper member having a flat surface facing the tip of the nozzle is arranged so as to be adjustable in position, and the spool is moved in a direction in which the nozzle approaches the flapper member. Pilot oil is introduced into the control oil chamber through a constriction section that is biased by a spring or hydraulic force and has different resistance changes due to oil viscosity than the gap between the nozzle tip and the flapper member. A temperature-compensated device characterized in that a pilot oil passage is provided to flow out of the body through the control oil chamber, and the spool is pressed against the biasing force of the spring or oil pressure by the pilot oil pressure acting on the control oil chamber. Flow control valve.
