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.

Controlling the flow of fluids using solenoid-actuated valves

A proportional solenoid-controlled valve provides for precise control of fluid flow using a flat spring and a damper. The flat spring is three-lobed and is constrained on its outer diameter in one of six degrees of freedom. The damper has three outer lobes which are compressed between the armature assembly and the valve body. A spring-loaded seal configuration having an annular elastomer seal compensates for dimensional instability of the elastomeric seal material and the armature assembly.

Proportional solenoid controlled valve

A valve-proportional solenoid arrangement is provided in a unitary housing. The spring elements of the solenoid are mounted within this housing in the nature of a clamped cartridge. Fluid movement through the valve is adjustable by either movement of the valve seat or the solenoid polepiece within the housing. The solenoid elements are secured into the housing by a threaded cap at one end. The valve elements are secured into the housing by a threaded cap at another end. In alternative embodiments, to assist in threaded securing of the armature to the retainer, portions of the circumference are flattened, although without altering the working area of the magnetic field with respect to the polepiece.
