Abstract
An electromagnetic solenoid valve in which a projecting portion disposed on a coil bobbin is abutted against and engaged with a plate so that rotation of the coil bobbin is stopped. As a result of this simple construction, shortcircuiting between the terminal of the coil and the plate can be prevented.
Claims3
An electromagnetic solenoid valve, comprising:
- a coil bobbin;
- a coil being wound around said coil bobbin;
- a core being inserted into said coil bobbin;
- a plunger which confronts said core and reciprocates within said coil bobbin;
- a terminal for supplying a current to said coil, said terminal being fixedly attached to one end of said coil bobbin;
- and
- a polygonal plate disposed at said one end of said coil bobbin, for forming a magnetic path;
- wherein said coil bobbin is provided with a rectangular projecting portion, one side of which abuts against and is engaged with a linear edge of said polygonal plate to thereby prevent rotation of said coil bobbin and to prevent shortcircuiting between said terminal and said plate, and projecting portion comprising a terminal outlet provided for said terminal.
