Abstract

The operating shaft (6) is mounted transversely between the inlet (4) and exit (5) ducts in the body (1) and is fitted with O-ring seals (10, 11, 12). It is increased in size in the flow passage region and carries the main seal (9). The seal is part cylindrical in form but its axis is offset from that of the shaft. Both of these axes are offset from the longitudinal axis of the flow passage. The net effect of these offsets is to allow the seal only to come into contact with the body when the tap is closed to allow an unobstructed flow path when the tap is open. An exterior quadrant and stop (8) prevent more than 90 deg. rotation.
