ABSTRACT:
A solenoid valve including a body, plunger, stop, bobbin, coil, and strap is disclosed. One embodiment is a normally open solenoid valve and one embodiment is a normally closed solenoid valve. The bobbin, coil and strap are encapsulated by a glass-filled nylon cover. The strap and the glass-filled nylon restrain the stop. A body is ultrasonically welded to the glass-filled nylon cover. In the normally open embodiment a first body has a single port. In the normally closed embodiment a second body has two ports. The plunger includes grooves and sections of reduced diameter, or channels, which allow for communication between the stop and the body. A method for making the solenoid valve is also disclosed and claimed.
