ABSTRACT:
A diaphragm operated valve assembly is controlled by an electromagnetic valve assembly. A flat disc armature, which forms part of a flux path, is operable in an inner chamber to modulate the flow between the inner chamber and an exit port in response to an applied magnetic force. The level of the effective magnetic force is a function of the armature mass, and the pressure acting on the disc surface. A pole piece adjacent to the flat disc armature is slidably adjustable to establish a specified force to actuate the armature to the closed or sealing position. This specified force is proportional to the current flow through the winding of the electromagnetic valve assembly. Thus the armature operates to seal communication between the inner chamber and the exit port at a given pressure differential as a function of current flow. The travel distance between the armature and a nonmagnetic seal seat has been minimized by spring biasing the armature in proximity to the seal seat.
