Embodiment Construction

[0026] figure 1 The branch adapter 1 shown in to 3 is suitable for coupling to an upstream conduit C 1 and a downstream conduit C 2 in the pneumatic line between them. Catheter C 1 connected to a pressurized air reservoir, while conduit C 2 Connected to a system for actuating doors of railway vehicle cars into which the lines are incorporated.

[0027] The branch adapter 1 comprises a substantially T-shaped body, wherein, in the conduit C 1 and C 2 The portion 12 extending therebetween defines a duct C forming part of the same pneumatic circuit 3 . Body 11 also includes a substantially perpendicular to the pipe C 3 Extending in the direction of and defining within it a center axis X for accommodating a longitudinal axis of the cavity 14 ie the portion 13 14 -X' 14 The portion 13 of the central cavity 14 of the slide 20 is translated. exist figure 1 Middle, double arrow F 1 represents the possible movement of the slider 20 in the cavity 14 .

Abstract

The branch adapter defines a plug-in quick-connect element (1) provided with a closing valve (23) and a slide mounted in the body (10) of said branch adapter (1) The load lock (40) on the upper, and through an opening (41) for cooperating with a part (116) of a plug-in connection element (101). The wall of the opening (41) has a structure (115) complementary to the structure (115) provided on the plug-in element (101) and keeps the plug-in element fitted in the two states of the plug-in element (1) structure, these states are mutually staggered parallel to the assembly direction (XX') of said elements (1, 101). Said valve (23) is adapted to actuate an auxiliary valve (24) when the plug-in element (101) is held by said lock (40) in said second mating state (Fig. 3, Fig. 4). ) to interrupt the lines (C1, C2, C3).

Description

technical field [0001] The invention relates to a branch connection for a pneumatic circuit, to a pneumatic circuit equipped with such a branch connection and to an assembly comprising such a circuit. Background technique [0002] In the field of railway vehicles, it is known to use a pressurized gas line to automatically control railway car doors. Such lines are generally equipped with a pressure gauge indicating the pressure of the gas in the line. In addition, the line is designed to be periodically connected to a source of pressurized fluid, such as a compressor, through a suitable filling device. Such systems are complex and expensive, not easy to maneuver, and can be time consuming. In addition, the number of potential sources of air leaks necessitates frequent inspections, especially as this line concerns the safety of persons transported in such vehicles. [0003] US Patent No. 3987817 discloses how to equip a branch adapter with a pilot valve that can test a pist...
