Abstract
An electromagnetic pressure regulating valve includes a hollow core, a coil surrounding the core and a plunger for applying a load to a valve member through a shaft fitted in the hollow of the core, so that the pressure regulating valve is actuated when an electric signal is fed to the coil. A bushing is mounted in the hollow portion of the core for supporting the shaft for sliding relative to the core and is made of a resin material on at least its sliding face contacting the shaft. An oil passage is provided in the valve for circulating a lubricant to lubricate the areas of sliding contact between the bushing and the shaft.
