    摘要： The invention relates to a high pressure pump of a fuel injection system of an internal combustion engine, having a pump housing 1 in which a pump camshaft 2 is rotatably mounted and interacts with a pump piston base 15 of a pump piston 5 by means of a roller tappet 4 disposed in a tappet body 10 and engaged with an inner annular flange 18 of the tappet body 10, said pump piston being displaceable up and down in a pump cylinder 8 disposed in the pump housing 1 and covered by a pump cylinder head 7, forming a pump working chamber 6. A spring disc 16,16a rests on the inner annular flange 18 opposite the roller tappet 4 and encloses the pump piston base 15, and a pump spring 17 is disposed between the spring disc 16,16a and the pump cylinder head 7. According to the invention, noise emission behavior of a generic high pressure pump is improved. Said aim is achieved in that a clearance compensation device is provided for compensating for a clearance between the pump piston base 15, the roller shoe 12, and the spring disc 16,16a.

    摘要： The invention relates to a high pressure pump (1), which is used in particular as a radial or series piston pump for fuel injection systems of air-compressing, self-igniting internal combustion engines, comprising at least one pump assembly (6) and one drive shaft (3) which comprises at least one cam (5) assigned to the pump assembly (6). The pump assembly (6) comprises a roller (23) running on the running surface (24) of the cam (5), a roller shoe (22) which receives the roller (23), a tappet body (20) in which the roller shoe (22) is introduced, a pump piston (11) which can be actuated in an actuating direction (13) by the cam (5) by means of the roller (23) and the roller shoe (22) and a carrier element (25) which carries the pump piston (11) opposite the actuating direction (13). According to the invention, the carrier element (25) is designed as a partially elastically deformable carrier element (25). The carrier element (25) according to the invention further comprises at least one elevation (37) facing the roller shoe (22) on which the pump piston (11) is supported. A play between the pump piston (11) and the roller shoe (22) can thus be reduced according to the invention in such a manner that undesired noises can be reduced.
