(54) | Combined stop-cock chamber and surface box |
(57) A combined stop-cock chamber and surface box comprises a plastic tube in two parts
10,11. The upper part 11 forms a surface box and is telescopically attached to the
lower part 10 which houses the stop-cock. The two parts can be resiliently supported
on a plastic plate to allow the surface box to be depressed resiliently by a load
such as a vehicle wheel. A ball valve housing 20 is moulded in the lower part 10 to prevent back siphonage. |
