Abstract: A compact fluid flow control valve is provided which effectively and predictably controls the flow of fluid using a minimum number of components to permit inexpensive manufacture and assembly. The control valve includes a one-piece valve plunger guide and stop which extends through an aperture formed in a stator of the solenoid assembly. The valve plunger guide and stop includes an integral guide surface for guiding the valve plunger through reciprocal movement within the aperture of the stator, an integral stop surface positioned for abutment by the valve plunger when in the energized position to define a minimum air gap between an armature and the stator. The one-piece valve plunger guide and stop reduces the number of parts of the control valve to achieve simplicity in structure and lower costs while avoiding the need for a shim to set the minimum air gap. The present control valve also includes a plunger overtravel impact limiting device including a movable valve head and a hydraulic damping device.

Abstract: An electrically operating three-way control valve adapted to fit with a bore of a cooperating apparatus. The three-way control valve including a low pressure seat and a high pressure seat. The three-way control valve further including movable valve means having a self aligning closure element for seating upon the high pressure valve seat.

Abstract: A solenoid control valve comprising a valve body enclosing an armature and reversible valve means including a valve seat adapted to be received within the valve body including at least one flow passage and a movable valve closure element such that when said valve seat is received in one orientation the solenoid control valve is of the normally open variety and when inserted in an opposite orientation said solenoid control valve is of normally closed variety.

Abstract: An electrically operated control valve adapted to fit within a bore of a cooperating apparatus. The valve including an interchangeable stator and lower body member. The valve further includes a valve means having a swivable self-aligning valve closure element.
