ABSTRACT:
A flow control valve unit includes a pressurized fluid inlet, a pressurized fluid outlet, a pressurized fluid chamber in which is positioned a stationary seat member, a partition member dividing the pressurized fluid chamber into a first section in constant communication with the inlet and a second section that communicates with the outlet via a center opening in the stationary seat member, an orifice for communicating said first and second sections to each other, and a through hole formed in the partition member. A movable rod is positioned within the pressurized fluid chamber and extends through the through hole in the partition member. The movable rod has a sealing portion at one end for opening and closing the center opening in the stationary seat member during movement of the stationary member. A spring is operatively associated with the movable rod for urging the movable rod in a direction which causes the sealing portion to close the center opening. A movable magnetic body is disposed in the first section and is operatively connected to the movable rod, and an electric coil is provided for generating a magnetic force that urges the movable rod via the movable magnetic body in a direction to cause the sealing member to move away from and open the center opening.
