摘要： A quick-coupling between a male part (90) and a female part (92) has provided in the cylindrical end-part (134) of the male part an axially displaceable piston body (106) provided with sealing ring (108), and a sealing sleeve (134) which is provided with a sealing ring (164) and which is axially movable in the female part around a stationary piston body (138). Insertion of the male part into the female part causes the piston bodies to be brought into engagement with one another, while the cylindrical end-part is pressed inwardly by the sealing sleeve of the female part. Each of the piston bodies and respective sealing rings (108, 164) coact with a respective, axially movable valve sleeve (122, 156), in a manner such that, until the piston bodies have reached an intermediate position, a through-flow channel (132, 145) is held closed by means of a gap closed by the valve sleeve until respective sealing rings have been moved by relative displacement from one side of the gap to the other side thereof, whereafter continued displacement of the piston bodies to their respective end positions in the coupled state of the coupling causes the gaps to open for flow therethrough.

摘要： Un raccord à action rapide entre une pièce mâle (90) et une pièce femelle (92) comporte dans la partie terminale cylindrique (134) de la pièce mâle un corps de piston axialement mobile (106) pourvu d'un joint d'étanchéité torique (108), ainsi qu'un manchon d'étanchéité (134) qui est muni d'un joint d'étanchéité torique (164) et qui est axialement mobile dans la pièce femelle autour d'un corps de piston fixe (138). L'introduction de la pièce mâle dans la pièce femelle amène les corps de piston en prise l'un avec l'autre, pendant que la partie terminale cylindrique est comprimée vers l'intérieur par le manchon d'étanchéité de la pièce femelle. Chacun des corps de piston et les joints d'étanchéité toriques correspondants (108, 164) coopèrent avec un manchon de soupape axialement mobile correspondant (122, 156), de sorte que, jusqu'à ce que les corps de piston aient atteint une position intermédiaire, un canal à courant traversant (132, 145) est maintenu fermé par l'obturation d'un espace libre par le manchon de soupape jusqu'à ce que les joints d'étanchéité toriques correspondants aient été mis en mouvement par déplacement relatif d'un côté à l'autre de l'espace libre, le déplacement continu des corps de piston vers leurs positions terminales respectives dans la position raccordée du raccord entraînant ensuite l'ouverture des espaces libres et le passage à travers ceux-ci de l'écoulement.

摘要： The invention relates to a coupling for coupling together hoses or pipes for pressure medium. The coupling comprises a coupling sleeve (1) and a nipple (2) insertable therein. The coupling sleeve (1) comprises a valve device for opening the flow-through of pressure medium as the nipple (2) is inserted to its engagement position and consists of a sleeve-shaped front part (5) and a sleeve-shaped rear part (6). According to the invention, the front part (5) is rotatable but axially essentially non-displaceably joined to the rear part (6) by means of a resilient lock ring (7). Furthermore, the valve device comprises a valve body (15) in the form of a sleeve, a valve seat (16) for cooperation with the valve body (15) and a blocking sleeve (14) for cooperation with the nipple (2) upon insertion thereof.
