Abstract

Dans le dispositif de l'invention, une chambre disposée à l'extérieur du logement (2) comporte deux passages mutuellement opposés (10, 11) dont les ouvertures d'entrée dans la chambre sont entourées par des surfaces d'étanchéité (12,13) et qui sont reliés chacun, via une conduite à pression (14, 15), à l'une ou l'autre des tubulures (3, 4) raccordées au dispositif d'arret (1) tandis que, dans la chambre et transversalement à l'axe des passages (10, 11), débouche une autre conduite à pression (17) qui communique avec l'espace intérieur du logement(2) du dispositif d'arret (1).In the device of the invention, a chamber arranged outside the housing (2) has two mutually opposite passages (10, 11) whose entry openings in the chamber are surrounded by sealing surfaces (12, 13) and which are each connected, via a pressure line (14, 15), to one or other of the pipes (3, 4) connected to the stop device (1) while, in the chamber and transversely to the axis of the passages (10, 11), opens another pressure line (17) which communicates with the interior space of the housing (2) of the stop device (1).
