Abstract: A device for controlling the displacement of a moving member by means of of a fluid distributor connecting a single-acting actuator for displacing the moving member to a source of fluid under pressure and to an exhaust, wherein the fluid distributor comprises a fixed element (68) having hoses providing fluid connections to the actuator, to the source of fluid under pressure, and to the exhaust, a moving element (64) constrained to be displaced by manually-operated control means, and a moving element (66) constrained to move with the moving member or the piston rod of its actuator. The invention is particularly applicable to controlling the displacement of flaps in an installation for heating and ventilating or for air conditioning a motor vehicle.

Abstract: The invention relates to a joint for connecting an elastically-deformable hose (14) and a rigid tube (22) having a smooth cylindrical outside surface. The tube (22) has a radial projection (26) on its outside surface which constitutes an abutment for the end of the hose (14) and also an anchor point for a clamping ring (28). The invention is applicable to mounting rubber hoses to rigid water inlet and outlet fittings on heat exchangers in motor vehicles, in particular.

Abstract: The device for controlling the displacement for a moving member such as a flap (46) includes a fluid distributor valve (10) actuated by control means (18) and suitable for connecting a single-action actuator (38) to a source of fluid under pressure, or to an exhaust, or for isolating said actuator from said source and said exhaust. The piston rod (40) of the actuator is connected to a moving element (14) of the distributor valve and also to the moving member (46) by common motion transmission means. The invention is applicable, in particular, to controlling flaps in installations for heating and ventilating or for air conditioning motor vehicles.
