Abstract (en)
A fuel pump unit for dispensing vehicle fuel from a fuel container (2). The fuel pump unit comprises a motor (3) which drives at least one pump assembly (4) and one gas recirculating means (5) or at least two pump assemblies (4) at the same time. Each pump assembly (4) has a primary fuel conduit (6) extending from the fuel container (2) to a delivery nozzle (7). A pump means (9) contained in a pump housing (8) is arranged in the primary fuel conduit (6). A metering means (12) is also arranged in connection with the primary fuel conduit (6) to meter the dispensed quantity of fuel. A safety valve (20) is arranged in the pump assembly (4) in connection with the primary fuel conduit (6) to reduce pressure spikes therein. In the pump assembly (4) there is also a secondary valve (18) which is arranged in a secondary fuel conduit (11) to open and close, independently of the safety valve (20), when the dispensing of fuel from the delivery nozzle (7) is finished and initiated, respectively. <IMAGE>
