CS237785B1 - Variable inductance - Google Patents

Abstract

Variable inductance includes winding with skeleton and shielded magnetic circuit, folding from movable and fixed parts, v which is the tuning core. Skeleton no moving parts are attached to the winding magnetic circuit. Inductance has increased stability against and can be in two variants design. In the first variant, the magnetic circuit the solid part is in the shape of a calyx with a thorn whose height is equal to half cup height and moving part, shaped blade, with center hole and is located inside the chalice. In the second variant, the magnetic circuit the solid part is in the shape of a calyx with thorn and movable - in the shape of a calyx without a mandrel whose internal diameter is 2 to 10% greater than the outside diameter of the hard cup.

Claims (2)

237785 SUBJECT OF HERE Ol Z Π 1. Variable inductance, including! a winding on the skeleton and a shielded magnetic circuit comprising a predetermined displacement along the axis of the magnetic circuit of the movable part; a skeleton with a winding and a fixed part, in the shape of a cup with a mandrel, which is provided with a aftercare core, in that, in order to increase fault stability, the fixed portion of the magnetic circuit has a height of darkness equal to half the height of the groove and the movable portion, for example, in the form of a disk, is provided with a central aperture while being located within the fixed portion. 2. The inductance according to claim 1, characterized in that the movable part of the magnetic circuit is in the form of a calyx without a darkness, the inner diameter of which is 2 to 10 * greater than the outer diameter of the solid cup. Recognized by the invention on the basis of the results of expertise, conducted by the State Committee for Inventions and Discoveries of the USSR, Moscow, SU. 1 drawing
