とを特徴とする電磁レリーフ弁。 The spool is slidably fitted into the valve body,
A valve seat member having a valve seat surface opening a relief passage into which pressure fluid is introduced is provided in the valve body opposite to one end of the spool, and a ball seat that contacts a ball valve that opens and closes the relief passage and the spool are connected to each other. A spring that urges the ball valve toward the valve seat surface is interposed between one end and the spring is applied in accordance with the amount of movement of the spool by a control current applied to a solenoid provided in the valve body. In the electromagnetic relief valve configured to vary the force, the ball seat is such that when the ball valve is at its maximum lift, most of the ball seat is in contact with the opening edge of the relief passage to the valve seat surface and the ball valve. An electromagnetic relief valve characterized by having a shape located inside a conical surface.
