Abstract
The present invention provides a sealing arrangement between a flow regulator and a shut-off valve attached to an oxygen cylinder. The shut-off valve includes a casing which is adapted to be mounted to an oxygen cylinder containing oxygen gas or an oxygen enhanced gas, a side wall defining a part of the casing. A female outlet port is defined in the side wall of the casing. The flow regulator includes a metallic cylindrical body which has first and second end faces. A yoke extends from the first end face of the cylindrical body. A screw bolt, which has an end facing the first end face of the cylindrical body, operates with the yoke to clamp the casing of the shut-off valve between the first end face of the cylindrical body and the end of the screw bolt. A male inlet port extends from the first end face of the cylindrical body into the female outlet port of the shut-off valve to receive the oxygen gas or the oxygen enhanced gas. An o-ring is provided around the inlet port of the flow regulator so that the o-ring is clamped between the first end face of the cylindrical body of the flow regulator and the casing of the shut-off valve when the flow regulator is secured to the shut-off v…
