Abstract:
A solenoid valve assembly comprising:a coil having a coil axis;a first armature and a second armature, the first and second armatures being axially moveable in first and second opposite directions along the coil axis and having valve coupling portions extending out of the coil in the first direction;a first valve and a second valve, the first valve having a first valve moveable portion and a first valve seat, the first valve moveable portion being spaced from the first valve seat when the first valve is in an open position, the first valve moveable portion being seated against the first valve seat when the first valve is in a closed position, the second valve having a second valve moveable portion and a second valve seat, the second valve moveable portion being spaced from the second valve seat when the second valve is in an open position, the second valve moveable portion being seated against the second valve seat when the second valve is in a closed position, the second valve seat being independent of the first valve seat, the valve coupling portion of the first armature being operatively connected to the first valve moveable portion in a manner so that movement of the first armature along the coil axis moves the first valve between open and closed positions, the valve coupling portion of the second armature being operatively connected to the second valve moveable portion in a manner so that movement of the second armature along the coil axis moves the second valve between open and closed positions; andat least one of the first and the second armatures is responsive to a magnetic field generated by the coil.
