ABSTRACT:
An electromagnetic valve assembly including a housing, a diaphragm member provided in the housing and defining first and second chambers therein, a first heat conducting plate member secured to the diaphragm member, a heat conductive output member secured to the first heat conductive plate member and extending outside of the housing, a heat conductive spring member one end of which is engaged with the heat conductive plate member, the spring member being positioned within the first chamber and normally biasing the diaphragm member in one direction, a solenoid coil positioned in the first chamber energized in repsonse to an electric signal, a contact operatively associated with the solenoid coil movable in response to energization of the solenoid coil, a first and second pressure source, a first valve member controlling fluid communication between the first chamber and the first pressure source in response to movement of the movable contact, a second valve member controlling fluid communication between the first chamber and the second pressure source in response to movement of the movable contact, and second heat conductive plate member positioned between the solenoid coil and an opposite end of the spring member for transmitting heat generated by the solenoid coil to the spring member.
