COMMAND APPARATUS

Abstract

The invention relates to automation, and more specifically to systems for delivering electrical, pneumatic, and hydraulic commands to actuators. The objective of the invention is to improve the operational reliability of a control unit design in the event of damage to the walls of an elastic torus. The control unit comprises a housing consisting of a base and a support, switching devices mounted on the base and support of the housing, and a switching drive for the switching devices, consisting of two drums on which a cable is wound with a torus with a filler placed on it, wherein the inner walls of the torus are helically twisted relative to the central axis of the torus. The torus filler is designed as a toroidal two-layer insert, the upper layer of which is made of an elastic porous material impregnated with an antifriction technical compound, and the inner layer is made of a rigid tube, the inner diameter of which exceeds the diameter of the helically twisted inner walls of the torus.
