Abstract
A solenoid assembly made with a one-piece metallic valve body having: a closed end; an open end; a central opening that communicates with multiple ports and an attachment portion adjacent to the open end. A movable armature positioned in the central opening has a free end that extends beyond the open end. A coil bobbin receives the free end of the movable armature and acts in response to electrical signals. The housing enclosing the coil bobbin attaches to the valve body to unify the coil bobbin and valve body as a solenoid.
