Patent ID: 7850767

Claim:
An anti-foaming degassing device for use in fuel dispensing equipment, particularly in biofuel dispensing equipment, having: a pump for circulating the fuel drawn from a storage tank, a degassing enclosure, particularly of the vortex type, supplied with a mixture of liquid fuel and gas by an inlet pipe connected to the outlet of the pump, and provided with two outlet pipes, namely a lateral pipe for the degassed liquid fuel and an axial pipe for a gas-enriched fuel fraction, a separating vessel at atmospheric pressure, connected to the axial outlet pipe of the degassing enclosure, in which the liquid fuel contained in the gas-enriched fraction is separated by gravity before being transferred again towards the suction end of the pump, this separating vessel being provided with a safety aperture enabling the separated gases to be discharged to the outside, and control means connected to the axial outlet pipe of the degassing enclosure to make it possible to vary the flow rate of the gas-enriched fraction collected by this pipe according to its gas content, characterized in that the axial outlet pipe of the degassing enclosure opens in the lower part of the separating vessel, into the gravity-separated liquid fuel, in such a way as to prevent the formation of foam in this vessel.
