PRESSURE REGULATING VALVE

摘要

PROBLEM TO BE SOLVED: To provide a pressure regulating valve capable of preventing noise likely to generate due to a jet flow of fluid even if the jet flow is generated.SOLUTION: A pressure regulating valve 1 includes a piston 4 and a poppet 5 which are provided in a pore (fluid passage) 31 formed in a body 2, and a connection section 7 which is loosely inserted into a through-hole 61 of a throttle section 6 so as to connect the piston 4 and the poppet 5. The throttle section 6 and the connection section 7 satisfy a relationship shown by an expression (1): L≥4(d1-d2), thereby suppressing generation of eddy current M due to a jet flow of high-pressure fluid to prevent noise even if the jet flow is generated on an outlet side (downstream side 31b) of the throttle section 6.
