Abstract
A relatively rugged and simple solenoid-actuated valve () is disclosed having a coil assembly (), including a bobbin (), a winding () for generating a magnetic field, and a flux path bracket (). A fixed pole piece () extends into the axial volume defined by the bobbin. The coil assembly may be encased in a plastic outer body (). An armature () is slidably disposed in the axial volume and a valve seat () closes the opposite end of the axial volume. A conical spring () biases the armature toward a first position against the valve seat. An inlet fitting () and an outlet fitting () fluidly connect to the axial volume. The armature is movable by the magnetic field generated by the winding from the first position to a second position away from the valve seat, such that the valve can be selectively opened and closed.
