Abstract: A valve for a vapour recovery system including a valve body having an inlet and an outlet, a valve seat within the valve body, a valve closure member releasably engageable with the valve seat, a socket portion for receiving a pipe member, a plurality of engagement members configured to be releasably engageable with a portion of a pipe member received in the socket portion for releasably retaining the pipe member in the socket portion, and an actuation member mounted on the valve body. The actuation member includes a recess for receiving each of the engagement members and is displaceable between a first position in which the engagement members are received in the recesses in the actuation member, and a second position in which the actuation member urges the engagement members inwardly towards a deployed configuration in which they engage with and retain a pipe member located in the socket portion.

Abstract: A water tap has a closure member in the form of a rubber or like cup 34 located in a chamber in carrier 32. The base of the cup extends across the port 28 which is to be closed when the tap is in "off" condition and the base of the cup has a hole 38 registered with the port in that off condition. Hence water can flow into the cup and the water pressure in the cup acts to hold the cup on the seat whereas pressure in the port acts against the base of the cup in the opposite direction but on a smaller area of cup. Hence the higher the water pressure the better the seal.

Abstract: A mixing tap for a kitchen sink or like comprises a functional assembly of water ways in a body with control valves enclosed in a shroud for aesthetic considerations. The shroud is generally tubular with a second part and these two parts meet about an axis of the control valve normal to the axis of the spouts 22 so that a seamless smooth exterior can be provided on the spout.
