<p>PROBLEM TO BE SOLVED: To provide a pressure reduction valve for interrupting pressure fluid flowing from a primary port into a secondary port when a secondary pressure becomes a set value, while holding the secondary pressure at the set value without causing a change of the secondary pressure with a change of a primary pressure.SOLUTION: The pressure reduction valve includes a valve body 11, a stepped cylindrical sleeve 16 inserted through the valve body 11, an adaptor 12, a primary pressure chamber 17 formed in the sleeve 16, a secondary pressure chamber 34 formed in the adaptor 12, a pressure reduction valve seat 19 formed in a boundary area between the primary pressure chamber 17 and the secondary pressure chamber 34, a pressure reduction member 21 provided approximately coaxial with the primary pressure chamber 17, a first elastic body 33, a ring member 28, a screw member 30, and a through-hole 26a formed in the pressure reduction member 21.</p> |
