The air flows around the outside surfaces of the fins so that the heat transfers from the heated fluid into the air stream.

Abstract: A long-proportional-stroke force motor which outputs force proportional to the exciting current. The motor has a magnetic circuit wherein a non-magnetic spacer is positioned axially between a magnetic guide and a magnetic sleeve. An armature moves within a central opening defined by the guide, the spacer and the sleeve. An end portion of the guide, adjacent to the spacer, has a sectional profile through a stepped surface facing radially outward and the corners of the steps define a curve which satisfies the following expressions: ? Y ? X > 0 , ? ? 2 ? Y ? X 2 > 0 , where X is a coordinate on an X-axis corresponding to a central axis of the guide; wherein the armature is moved in a direction along the X-axis by application of exciting current to a coil surrounding the guide, spacer and sleeve; and Y is a coordinate on an axis orthogonal to the X-axis.

Abstract: There is provided a long-proportional-stroke force motor whose force vs. stroke characteristic provides a long stroke in which a constant force is output proportional to the exciting current in magnitude without involvement of problems in actual use, and which does not impose any limitations on the stroke so as to effectively use the stroke. A long-proportional-stroke force motor 1 includes a magnetic circuit configured such that a spacer 12 made of a non-magnetic material intervenes between a guide 11 made of a magnetic material and a sleeve 13 made of a magnetic material, and an armature 3 provided movably within the magnetic circuit.

Abstract: A servo valve has a miniature force motor embedded in a main fluid chamber to directly operate between two nozzles to generate a differential pressure in two ports. The miniature force motor includes two disc ring-shaped magnets in opposing magnetic orientation, an armature base and poppet ends of magnetic material coupled to an armature shaft having pilot ends that interface to form the pilot stage valves at each armature shaft end. The armature shaft extends through a center hole in the magnets, armature base, and the poppet ends and engages bearing elements at each end allowing lateral armature motion. Two elastic members provide restoring forces to the armature assembly. Guide/stops have shaped magnetic surfaces to control the magnetic path and to linearize the force versus stroke and to increase the proportional stroke of the armature.
