Fuel pump

The invention relates to a pump (110) for a fuel delivery system. The pump (110) comprises a main housing (112) and a plunger housing (114) arranged to be coupled to the main housing (112) so as to define a compression chamber (116) therebetween. The main housing (112) and the plunger housing (114) include respective opposed first (113) and second (118) faces arranged to form a seal therebetween. The main housing (112) includes a protruding portion (117) protruding from a first face (113) of the main housing (112) into the plunger bore (140) through an opening in a second face (118) of the plunger housing (114). 本发明涉及一种用于燃料输送系统的泵(110)。泵(110)包括主壳体(112)和柱塞壳体(114)，所述柱塞壳体被布置成联接到主壳体(112)，以便在它们之间限定压缩室(116)。主壳体(112)和柱塞壳体(114)包括相应对置的第一(113)和第二面(118)，它们被布置成在其间形成密封。主壳体(112)包括突出部分(117)，所述突出部分从主壳体(112)的第一面(113)通过柱塞壳体(114)的第二面(118)中的开口突出到柱塞孔(140)中。
