<p>In a fuel supply pump, a piston (24) performs displacement along a cylinder (20) formed in a pump (19) with reciprocating rectilinear motion which has a fuel suction stroke which sucks fuel into a pumping chamber (26) and a transport stroke which transports the fuel to an ejector (13). The fuel is sucked from a supply chamber (25) through the piston (24). Tubular bodies (39, 44; 39; 53, 57) which limits two passages (45, 46; 56, 60) are disposed in the supply chamber (25). The two passages (45, 46; 56, 60) are basically concentric and are communicated with each other through at least one opening (47; 58) which is formed in the tubular bodies (39, 44; 39; 53, 57) themselves.</p> |
