In an angled connection in accordance with the invention, the one-way flow of fluid at a restricted flow rate is provided in a direction opposite to direction F by co-operation between a wall (23) having fixed orifices and a plug (26) having moving openings (31). The area of overlap between the fixed orifices through the wall (23) and the moving openings (31) is adjustable by rotating the plug (26). Flow in the opposite direction, i.e. the direction of arrow F, is provided at full flow rate by openings (22) provided through the plug (26), which openings are closed by a non-return valve (37) which allows flow in said direction F. The plug (26) and the wall (23) are pressed together in sealed manner by a resilient member (33). The plug (26) is rotated by an outside ring (38) on the tubular portion (5) of the connection, said ring being coupled to the plug via a slot through the tubular portion (5), which slot is isolated in sealed manner from the path of fluid flow through the connection.

Angled pneumatic connection including means for regulating a one-way flow

A switch provides for cutting the pressure feed for distributors placed downstream of it, and for coupling the feed of these distributors to an exhaust of the switch itself, and has faces for connection with faces of the distributors, channels for circulation of exhaust fluid, members for connection with adjacent distributors, and is adapted for mounting on a conventional profiled element. The switch is particularly advantageous for ensuring the control of the feed of one or of several jacks coupled to distributors.
