Abstract: A clutch for a motor vehicle having an annular diaphragm (54) with a concave clutch characteristic curve and a pneumatic actuator (76) acting on the diaphragm (54) for clutch release. A mechanism (86, 88) is provided to generate a supplemental resistant force during clutch release to that developed by the diaphragm (54). The invention is particularly applicable to industrial vehicles equipped with a pressurized gas source.

Abstract: The invention concerns a clutch, in particular for a motor vehicle, comprising an annular diaphragm (54) with concave clutch characteristic curve and a pneumatic actuator (76) acting on the diaphragm (54) for clutch release, means (86, 88) being provided to generate during clutch release a resistant force which supplements that developed by the diaphragm (54). The invention is particularly applicable to industrial vehicles equipped with a pressurized gas source.

Abstract: The invention proposes a feed pipe coupling for a pressurised fluid system, characterised in that the branch of the spring clip which includes the locking portion is configured generally as a hairpin having a radially internal, locking, first branch portion of which the locking portion is a part, together with a radially external, connecting, second branch portion which is connected at each of its ends, firstly to the operational locking branch portion through a bent connecting portion, and, secondly to the central connecting branch of the spring clip, in such a way as to give the locking branch a capacity for elastic deformation in the general transverse plane of the spring clip.
