られていることを特徴とする圧力制御弁。 A valve body provided in a liquid passage connecting an inlet side port and an outlet side port to open and close the liquid passage, a spring urging the valve body in a direction to close the liquid passage, and a spring presser pressing the spring. , when the liquid temperature is lower than a predetermined value, the spring presser reduces the pressing force on the spring to facilitate opening of the liquid passage, and when the liquid temperature is above the predetermined value, increases the pressing force on the spring. A pressure control valve characterized in that it is made of a shape memory alloy that changes shape at a predetermined temperature so as to increase the biasing force in the direction of closing a liquid passage.
