THERMOSTATIC SWITCH Russian patent published in 1994 - IPC

FIELD: heat engineering. SUBSTANCE: a V-shaped element, whose surface is engageable with the pusher at an angle to the disk plane, is placed between the pusher and contact spring. Adjustment of contact breaking at rotation of the adjustable spindle is effected by displacement of the wedge in parallel with the disk plane, and of the pusher contact point - along the wedge inclined surface. An increase of power handling is provided by the increase of the breaking (making) rate of the contacts at "flapping" of the disk due to an additional vertical displacement of the point of contact of the wedge with the pusher on inclined plane. EFFECT: enhanced power handling and provision of smooth adjustment. 2 dwg
