にした可変絞り弁において、上記スプールにら旋
溝を形成して制御部を構成してなり、上記スプー
ル孔内に位置したら旋溝の長さによつて、流量制
御をするようにした可変絞り弁。 A high-pressure port and a low-pressure port are arranged in series, and a spool hole is formed between the flow paths connecting these two ports, and a spool is slidably installed inside this spool hole, so that the spool can be moved relative to the spool hole. In the variable throttle valve in which the opening area of the control section is made variable by making the opening area of the control section variable, the control section is configured by forming a spiral groove on the spool, and when located in the spool hole, the length of the spiral groove changes. A variable throttle valve that controls the flow rate.
