"textContent": "The invention relates to a pump (1) for delivering liquid at high pressure, especially for delivering fuel at high pressure to a common rail of a common rail fuel injection system for an internal combustion engine. The pump (1) comprises a cylinder (2), a plunger (5) reciprocally driven by an eccentric (6) to pressurize a pump chamber (3) in the cylinder (2), a rider (8) mounted on the eccentric (6) to allow relative rotation of the eccentric (5), the rider (6) presenting a face (9) to the plunger (2), a tappet (10) supported on the face (8) of the rider (6) for transmitting reciprocal movement from the rider (8) to the plunger (5), and at least one rotatable bearing element (14) which supports the tappet (10) for relative transverse movement of the face (9) of the rider (8) during operation of the pump. According to the invention, the at least one rotatable bearing element (14) is accommodated at least partially recessed in a body (11) of the tappet (10). The invention further relates to a common rail fuel injection system for an internal combustion engine comprising a common rail for distributing fuel to a plurality of fuel injectors associated with combustion cylinders of the engine, and a pump (1) according to the invention for delivering fuel at high pressure to the common rail.",
