Abstract
A unit for coupling a displaceable operating member such as a bar or shaft with a regulating member, in particular a regulating rod of a fuel injection aggregate of an internal combustion engine, comprises a casing and a cam which can be clamped on the operating member, by means of a screw, to project therefrom. This cam which comprises an internally threaded nut engages the regulating member whose movement in one direction is limited by a stop or the like abutting organ. The operating member is provided with a transverse bore which can register with a bore in the casing, and a fixing pin is lodged in the casing bore and the transverse bore when the regulating members are in a basic position. In order to attain automatically the positioning of the cam and the operating member relative to each other, achieved by a basic adjustment, and to provide a relatively simple construction facilitating assembly of the unit, the internal nut threading is designed to be self-locking. The screw extends through the transverse bore of the operating member, and, in doing so, the direction of the force exerted on the cam by the screwing-down momentum of the screw corresponds to the direction of movement of the regulating member towards the stop.
