wires 71 connect to connector 70 and to controlled power source 72 controlled power source 72 can be simple as in the case of a direct current source controlled with manual switches or more complex as in the case of a computer controlled current relay system the wires 20 and 71 electrical connectors 50 and 70 will be specified to be of sufficient size to handle the amperage requirement of solenoid coils 16 and 17 abutting the electrical actuating assembly 9 within central cavity 11 are a pair of valve element support cylinders 26 and 27 each having an open end the open ends being disposed outwardly with respect to electrical actuating assembly 9 and whose outer surface of the closed ends each abuts plates 21 and 22 respectively the axis of valve element support cylinders 26 and 27 is collinear with the axis of solenoid armature 18 aperture 28 is provided in valve element support cylinder 26 and aperture 29 is provided in valve element support cylinder 27 to slidably permit the left end and right end respectively of solenoid armature 18 to extend therethrough within aperture 28 each near one end of aperture 28 are placed seals 30 and 31 to form a fluid seal within the annular space formed between the left end of solenoid armature 18 and the inner cyindrical surface of aperture 28 in order to prevent fluid reaching the electrical actuating assembly 9 similarly within aperture 29 each near one end of aperture 29 are placed seals 32 and 33 to.
