摘要： A quick-connect coupling for pressurized fluid lines includes a male element and a female element whose connecting ends are each closed off by valves. Each valve comprises a sealing member which engages with the sealing member of the other valve during connection. A return spring pushes the sealing member against a seat and an abutment limits the opening stroke of the sealing member. The abutment of the element under pressure is fixed and positioned in such a way that the sealing member engages with the abutment when the male and female elements are connected. The other abutment is mounted in the other element in a sliding manner and includes first and second sliding sleeves. The front end of a second of the sleeves forms a valve sealing member and includes holes located directly behind the sealing member enabling fluid to flow through the body. The rear end of the second sleeve is shaped for engagement with a front end surface of a first of the sleeves. The coupling furthermore includes means for locking and returning the sliding abutment to the forward position, which permits the rearward movement of the sliding abutment during connection of the male and female elements and the locking of the sliding abutment into a forward position once such connection is complete.

摘要： The invention relates to a quick-connect coupling for hydraulic fluid conduits. The inventive coupling consists of a male element and a female element comprising an outer tubular part and a mobile coupling part. In addition, joints are provided between the tubular parts and define chambers. According to the invention, during the coupling phase, one hydraulically-pressurised chamber can be communicated with an atmospheric pressure chamber, using at least one longitudinal groove or similar element which is disposed in the tubular coupling part or in the outer tubular part.

摘要： The invention concerns a method using steps of placing a tube in an opening matrix having an impression corresponding to the desired final external shape; inserting the end of the tube into a cavity of a shaping component, the cavity having a base, a side wall with adapted shape, and an opening opposite the base; pressing the end of the tube against the base of the cavity, leaving a clearance between the opening of the cavity and the matrix; applying an essentially axial force on the end of the tube, the zone application of the force rotating about a longitudinal axis of the tube thereby causing gradual deformation of the tube; withdrawing the end of the deformed tube outside the cavity of the shaping component and outside the matrix.
