Title: Fuel pump for automobile engine - has anti-pulsation diaphragm which also prevents flow of fuel to engine if vehicle overturns to prevent fire risk
IPC: F04B53/10
Filed: 1977-04-07
Abstract: The fuel pump for an automobile has a one piece valve chamber mounted above the main actuating diaphragm. Fuel flows in through the filter (11) and through the inlet valve (9) into the diaphragm chamber (6). The fuel is then expelled through the outlet valve (10) into the delivery chamber (3). The rise in pressure in the delivery chamber (3) deflects the anti-pulsation diaphragm (13) enabling the fuel to flow out through the delivery pipe (4). The anti-pulsation diaphragm (13) also prevents any fuel continuing to flow to the engine in the event of the vehicle overturning and so reduces the risk of fire. A small hole (16) in the diaphragm housing (12) equalises the pressure and acts as a dash-pot.
