More Information
Summary:An actuator including actuator base, bobbin, and pole piece forming a pocket for a ferromagnetic armature located therein. The actuator including a radial magnet and a solenoid coil. The solenoid coil is constructed and arranged to cause a linear displacement of the armature upon application of a coil drive current from a control circuit. The actuator may include a flexible membrane that partially encloses the armature to form an armature chamber filled with an incompressible fluid. In a valve design, a fluid flow is stopped by driving the armature to an extended position and thus the membrane against a valve seat. The fluid flow is opened by driving the armature and the membrane away from the valve seat int o a retracted position.
