CONTROL APPARATUS Russian patent published in 1995 - IPC

FIELD: electromechanics. SUBSTANCE: control apparatus has a base, a cam with a drive unit, a grooved disc, kinematically connected with the cam, output links, mounted with possibility of engagement with the cam and spring-loaded towards the cam; a disc rotation angle pickup. The disc, mounted on the base coaxially with the cam, is equal-sized with the last; the cam being helical of screw-like one. The disc is spring-loaded to the base through a frictional liner. The output links are mounted with a possibility of joining with the groove of the disc. The disc has rests on its surface, turned to the cam, for protrusion of the cam, providing a kinematic connection of the disc with the cam at position of joining of portions of minimum and maximum lifting of the cam profile with the groove of the disc. The apparatus is provided by a device for returning the cam (relative to the disc) in its initial position, that device is in the form of an elastic member, connected with the disc and the cam. The apparatus allows to realize a large number of operation modes in any desirable succession with use of a low-power drive unit. EFFECT: enhanced reliability and enlarged range of using. 2 cl, 6 dwg
