ABSTRACT:
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.
