Truck tank

Fuel tank

Discloses a double-walled fuel tank defining a chamber having carbon dioxide under pressure therein from a regulated source. The walls carry filler-pipe, vent-pipe and fuel-line housings which complementally receive a filler pipe, vent pipe and fuelline valve, respectively. The outer wall mounts pressure-relief valves. In an accident with imppact almost sufficient to rupture the outer wall, instantaneously, the pressure-relief valves automatically open to relieve the chamber pressure, and the build up of pressure on the fuel in the fuel tank causes the fuel-line valve to seat in closing relationship in its housing. In addition, upon rupture of the outer wall of the fuel tank in an accident, carbon dioxide pouring from the ruptured outer wall will smother the fuel tank to minimize any chance of fire or explosion.

A device used in liquid fuel dispensing systems to inhibit the infiltration of air into the product dispensing line due to thermal contraction. A fluid tight container (44) is connected with the product line (24) and supplied with fuel in an amount sufficient to make up the liquid volume loss caused by thermal contraction. A vent (78) for the container (44) is normally closed by a valve (62) under normal pressures of the dispensing system. When thermal contraction reduces the product line (24) pressure far enough to create a vacuum, the valve (62) opens the container vent (78) so that the fuel in the container (44) can flow into the product line (24) to keep it full or liquid and avoid drawing air into the line.

System and method for closing a tank opening

System and for sealing an opening of a plastic tank with a multilayer wall by means of a multilayer plate itself constituted by a polymer structure including at least one internal barrier layer and an exterior layer compatible with the exterior layer of the tank wall. The multilayer plate is welded over an opening in the tank and the plate and the wall of the tank are superimposed so that the number of superimposed layers is equal to the sum of the number of layers in the plate and the number of layers in the wall of the tank.

Vented valve assembly

In some embodiments, a vented valve assembly for attachment to a rigid container may include one or more of the following features: (a) a unitary tubular valve body of a generally cylindrical hollow form and having a liquid inlet end, and (b) a second end and a liquid outlet port, said liquid inlet end adapted for connection to a male spout on a wall of the rigid container, said liquid outlet port being exterior to the wall of the rigid container when the liquid inlet end is affixed to the spout, the valve body further including an air vent opening formed through a wall of the tubular valve body leading to a channel affixed to an inner wall of the tubular valve body, the channel having one open end.
