Title (EN) DEVICE FOR CONNECTING A TUBE TO A COUPLING
(FR) DISPOSITIF DE LIAISON D'UN TUBE A UN EMBOUT
Abstract:
(EN) A device for joining a tube (3) to a cylindrical coupling (1) defined by a front surface (6) and a coupling sleeve (11) of which a first section (12) comprises releasable fastening means (13) engageable with aligned means (5) on the coupling (1), while a second portion (14) axially adjacent to the first (13) comprises means (15) for preventing the removal of the end of the tube (3) inserted into the sleeve (11) and engaging the front surface (6) of the coupling (1). The sleeve (11) is provided with an internal guide ring (19) for guiding the end of the tube (3), the internal diameter (D) of the guide ring is substantially the same as the external diameter of the tube (3), and said ring includes a first portion (20) slidably mounted in the second section (14) of the sleeve (11), and a second portion (21) axially projecting into the first section (12) of the sleeve (11), whereas the coupling (1) is provided with a groove (7) formed in the front surface (6) thereof for receiving and centring the free end of the second projecting portion (21) of the ring (19) when the fastening means (5, 13) are in mutual engagement.
(FR) Dispositif de jonction d'un tube (3) à un embout (1) cylindrique limité par une face frontale (6) et un manchon (11) de raccordement dont une première section (12) comporte des moyens (13) de fixation démontables pour coopérer avec des moyens (5) disposés en correspondance sur l'embout (1) de raccordement, et dont une seconde section (14) adjacente axialement à la première (13) comporte des moyens (15) s'opposant à l'extraction d'une extrémité du tube (3) placé dans le manchon (11) et en butée contre la face frontale (6) de l'embout (1) dans lequel le manchon (11) est équipé intérieurement d'une bague de guidage (19) de l'extrémité du tube (3), le diamètre (D) interne sensiblement égal à celui externe du tube (3), possédant une partie (20) montée à coulissement dans la seconde section (14) du manchon (11) et une seconde partie (21) en projection axiale dans la première section (12) du manchon (11) tandis que l'embout (1) est pourvu d'une gorge (7) creusée dans sa face frontale (6) pour accueillir et centrer l'extrémité libre de la seconde partie en projection (21) de la bague (19) lorsque les moyens de fixation (5, 13) sont en prise.
