ABSTRACT:
A servo arrangement, especially for brake force amplifiers for automotive vehicles, in which a servomotor provides an auxiliary moment which is transmitted by a coil spring coupling to a linkage. The coil spring has a hook-shaped rear end adapted to be engaged by a first entrainment member connected to a power take-off means of the arrangement so as to tighten the coil spring about the peripheral surface of a cylinder driven by the servomotor and the front end of the coil spring, at which the first coil of the spring is outwardly bent in form of a spiral, is adapted to be engaged by a second entrainment member connected to operator controlled force applying means to expand the coil spring so that the latter may slip on the peripheral surface of the cylinder.
