Abstract

The invention provides a connector which comprises:
a. a chamber having an open upper chamber and a lower chamber,
b. an inlet connector and
c. an outlet connector formed in a floor of the lower chamber
wherein the inlet connector is supported above the open upper chamber by one or more arms; wherein the upper chamber has an upper chamber floor having an upper chamber outlet, the upper chamber is in fluid communication with the lower chamber by means of the upper chamber outlet; wherein the upper chamber outlet has a non-return valve which is arranged to open at a pre-selected pressure; and
wherein the lower chamber forms a flow conduit for receiving the valve when it is open; a shielded connector comprising a shield and the connector wherein the shield is shaped to cover the open upper chamber; and a valve assembly for use in the connector or shielded connector wherein the valve assembly comprises a stem, a biasing member for biasing the valve assembly into a closed position, a valve disc for sealing the outlet, an upper washer and a lower washer wherein the upper and lower washers support the valve disc such that the valve disc does not distort in use.
To be accompanied when published with Figure 4 of the accompanying drawings.
