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).
Claims13
A fluidic connection device for a fluid circuit, this device comprising:
- a first pipe comprising a main section of an internal first diameter (D1) and a secondary section having at least one internal second diameter (D2) greater than the first diameter (D1), the secondary section being located at one end of the first pipe and connected to the main section by a first shrinkage, this first pipe being made of a plastically deformable material and comprising a first external annular collar,
- a tubular end-piece comprising an end section of an external third diameter (D3) which is configured to be engaged along an axis in the secondary section of the first pipe, this end-piece comprising an external cylindrical shoulder,
- a first flange mounted around the secondary section of the first pipe and comprising a first orifice crossed by this secondary section, this first flange being configured to be supported axially on the first collar,
- a second flange mounted around the end-piece and comprising a second orifice crossed by this end-piece, this second flange being configured to be supported axially on the cylindrical shoulder, the first and second flanges being configured to be tightened one against the other in a connecting plane substantially perpendicular to said axis so as to bring the first collar closer to said cylindrical shoulder and to maintain the end-piece engaged in the first pipe,
- at least one element for attaching the first and second flanges one against the other, and
- a non-return insert valve mounted within said secondary section, and located axially between said first shrinkage and said end section,
- wherein said secondary section comprises a first segment of an internal fourth diameter (D2′) greater than the first diameter (D1), and a second segment of the internal second diameter (D2) located between the main section and said first segment, the second diameter (D2) being greater than the first diameter (D1) and less than the fourth diameter (D2′).
