Abstract
An electromagnetic pressure regulating valve includes a valve body and causes a valve body to move by an electromagnetic proportional solenoid to adjust an opening degree of a valve passage, thereby regulating secondary pressure to target pressure. A pressure return chamber is formed in the housing, and a diaphragm seal is provided at the valve body. The diaphragm seal receives the secondary pressure of the pressure return chamber to cause the valve body to move toward a closed position. A bearing member is provided between the valve body and the housing. In a gap between the valve body and the housing, a high-pressure sealing member is provided closer to the valve passage than the bearing member, and a low-pressure sealing member is provided closer to the bearing member than the high-pressure sealing member. A buffer chamber connected to a secondary port is formed between the sealing members.
