Abstract
The invention features a coupler that is substantially disposed around an armature, and is constructed to provide an axial force-transmitting relationship between a carrier and the armature for blocking and unblocking the passage of fluids between the first and second passages. The force-transmitting relationship is characterized by the carrier being capable of axial movement relative to the armature, while the carrier substantially following the motion of the armature for both blocking and unblocking the passage of fluids between the first and second passages. The coupler includes coaxially nested coupling and blocking springs that provide equal spring forces and are removed from the direct passage of fluid between the first and second fluid passages. The solenoid is reversible in orientation such that the electrical connectors can be situated on either the manifold face, or 180.degree. on the opposite face.
