  "textContent": "A fuel pump (10) for supplying fuel at high fuel pressures includes a stationary body (12) having a plurality of radial cylinders (42, 44) connecting with a central fuel chamber (64). Inlet and outlet passages (66, 78) communicate with the fuel chamber (64). Plungers (46, 48) are reciprocated in the cylinders by cam followers (56) reciprocable in follower recesses (58) of the body. A rotary internal cam (24) engages the cam followers (56) and is configured to reciprocate the plungers (46, 48) in timed relation to sequentially draw fuel from the inlet passage (66) into the central fuel chamber (64) and alternately force fuel from the central fuel chamber (64) to the outlet passage (78) in response to rotation of the rotary cam. A preferred embodiment includes paired smaller and larger diameter cylinders and pistons which are sequentially actuated in overlapping fashion to minimize pulsing of the pressurized fuel discharged from the pump into associated engine fuel lines.",
