Lever device for double-action remote-control
摘要:
Lever device for double-action remote-control, i.e. of rigid tie rods and/or flexible cables, consisting of a lever (12) rotatable in respect of a base element (13), connectable (in 14) to a carrying structure external to an operating machine in which the device (11) is contained into bellows (10) connected-to the base element (13) while the lever (12) is connected to a mobile component (15) from which the elements to fasten the ends of two cables (22) for remote transmission extend and the base element is coupled to two reaction sheaths (21) of the two transmission cables (22), three ball elements (16, 16'), placed at 90.degree. one from the other, extend from the mobile component (15), one of which (16') is inserted into a fixed bush (17) while the other two ball elements (16) are inserted into additional mobile bushes (18) in respect of the base element the bushes (17, 18) being made of plastic material, with good resistance to compression, and placed inside a ring element (23) obtained from a metal band integral with free ends of each one of the transmission cables (22).
