Abstract (en)
[origin: EP3176422A2] The present disclosure relates to a fuel pump (10) having a head member (12) provided with a blind bore (14) in which a piston (26) is adapted to perform a pumping cycle by reciprocating along the main axis (X1) of the bore (14) between a top dead center (TDC) position and a bottom dead center (BDC) position. Fuel is pressurized during the cycle in a compression chamber (30) defined between the top extremity (28) of the piston and the blind end of the bore (14). The piston (26) reciprocates under the influence of a rotating cam (36) cooperating with a follower assembly (34) combined to the piston (26). The pump (10) also includes a spring (46) compressed between the head member (12) and the follower assembly (34) in order to bias the follower assembly (34) toward the cam (36). An end cap (48) is mounted to the piston (26) for engaging the follower assembly (34). The end cap (48) may locate a spring seat member (44) or may form a spring seat member (44).
