Abstract: A non-return insert valve (100) for a fluid circuit, in particular of a vehicle, this valve (100) being configured to be inserted into a pipe (12) and comprising: a tubular body (102), a ring (104) comprising guides (140), a piston (106) configured to slidingly cooperate with said guides (140) and carrying a seal (146), and an elastically deformable member (108) for biasing said seal (146) in axial support against a seat (124) of the tubular body (102), said piston (106) comprising at its external periphery lugs (166) which are configured to be supported axially against an internal cylindrical shoulder (126) of said body (102), in order to precisely define a first position of the piston, the fluid being intended to flow between these lugs (166) when the piston (106) is in a second position.

Abstract: A fluidic connection device (10) for a fluid circuit, in particular of a vehicle, this device comprising: a first pipe (12), a tubular end-piece engaged in the first pipe (12), a first flange (16) mounted around the first pipe (12), a second flange (18) mounted around the end-piece, at least one element (20) for attaching the first and second flanges (16, 18) one against the other, and a non-return insert valve (100) mounted within the first pipe (12).

Abstract: Fluid connection device, in particular for a motor vehicle, includes a female nozzle having an internal fluid flow passage, and being configured to receive a male nozzle. A sensor senses that the male nozzle is received within the female nozzle, and an electrical plug electrically connects the sensor to an electrical power source. The sensor includes a flexible, electrically conductive dome located within the female nozzle. In a first position, the dome has a generally curved shape. When the male nozzle is inserted into the female nozzle, the male nozzle presses the dome to deform the dome into a second position. In the second position, the dome has a generally flattened shape and provides an electrical connection between two terminals connected to the electrical.
