Abstract

A solenoid valve including a non-sliding plunger assembly. The solenoid valve disclosed herein generally includes a plunger assembly that is moveably suspended within an internal chamber of a housing of the solenoid valve away from any sliding contact with adjacent surfaces. The plunger assembly may not be in sliding contact with any of the adjacent surfaces, and thus a radial gap may be defined between the plunger assembly and all non-moving, non-flexing features and surfaces of the solenoid valve. The solenoid valve may include a flexural washer that is resiliently flexible and is configured to enable selective axial movement of the plunger assembly in response to energizing the solenoid coil. In various embodiments, the flexural washer is configured to moveably suspend the plunger assembly within the internal chamber away from any sliding contact with adjacent surfaces.
