ELECTROMAGNETIC VALVE AND FLUID PRESSURE CONTROL DEVICE

Japanese Patent JP2017211083

A

PROBLEM TO BE SOLVED: To provide an electromagnetic valve which suppresses self-excited vibrations of a compression coil spring generated due to the flow of an oil liquid and allows a valve body to stably seat.SOLUTION: A compression coil spring stand 61 partitions a first oil chamber 51e into a first compartment chamber R1a with a compression coil spring 60 disposed and a second compartment chamber R1b with no compression coil spring 60 disposed, the compression coil spring 60 includes a contactable receiving face 61a1, and a valve body guide hole 61a2 through which a valve body 53 is inserted to guide the valve body 53, and is movable between a sheet 54 and the compression coil spring 60 along a central axial direction, the receiving face 61a1 is provided so as to be located at the other end side of a shaft 52 with respect to a second flow channel 51c1, and a notch 61b1 (a third flow channel) where the oil liquid flows in and out is formed at a position closer to one end side of the valve body 53 than the receiving face 61a1 on the compression coil spring stand 61.SELECTED DRAWING: Figure 2
