Service station fuel pump - is automatically switched off when vehicle fuel tank is full

摘要

Fuel from a service station storage tank (7) is delivered to the fuel tank of a motor vehicle through a filler gun (3). The interior of the gun is connected by a flexible pipe (9) to a suction pump (1) which produces a sub-atmos. pressure in the interior of the gun. This low pressure sets in motion the fuel pump (8) in the storage tank (7) so that fuel is delivered to the vehicle fuel tank. The air and vapour pumped out of the vehicle tank by the suction pump (1) flows into the storage tank to replace the fuel pumped out. When the fuel in the vehicle tank covers the inlet orifice (11) the pump (8) is automatically switched off. USE - Service station petrol pump.
