Definitions

  • the invention relates to a high-pressure pump, in particular a radial or linear piston pump. Specifically, the invention relates to the field of fuel pumps for fuel injection systems of air-compression, self-igniting internal combustion engines.
  • a high-pressure pump for a fuel injection device of an internal combustion engine has a pump housing, in which a pump element is arranged, which comprises a driven by a drive shaft in a stroke pump piston.
  • the pump piston is slidably guided in a cylinder bore of a part of the pump housing and limited in this one pump working space.
  • the pump piston is supported indirectly via a hollow cylindrical plunger on the drive shaft, wherein the plunger is slidably guided in a bore of a portion of the pump housing in the direction of the longitudinal axis of the pump piston.
  • the longitudinal axis of the plunger is substantially identical to the longitudinal axis of the pump piston.
  • the drive shaft facing end portion is a support member used in which a roller is rotatably mounted, which rolls on the cam of the drive shaft.
  • the axis of rotation of the roller is at least approximately parallel to the axis of rotation of the drive shaft.
  • the support member has on its side facing the drive shaft a recess in which the roller is mounted.
  • the high-pressure pump according to the invention with the features of claim 1 has the advantage that a running behavior of the roller on the tread of the cam improves, and that the Abschlappung the tread and the roller are designed so that in a centered basic position of the roller between an end portion of the roller and the tread is formed a gap. Specifically, the hydrodynamics between the roller and a roller shoe can be improved and at the same time an advantageous running behavior of the roller on the tread of the cam can be achieved.
  • the tread is convex in the region of the Abschlappung.
  • the Abschlappung of the tread is designed so that even in a decentered position of the roller between the end portion of the roller and the tread a gap is formed.
  • a constantly small gap can be ensured.
  • the Abschlappung on the camshaft the role can be centered on its path.
  • the roller In an occurring angular error between the roller and the cam of the drive shaft, the roller is guided by the bending of the roller caused by the pressing force from the pressure generation around the cam through the Abschlappung.
  • an oblique cam run-up of the roll is counteracted by the Abschlappung. Specifically, thus a side start of the role can be prevented or at least avoided.
  • the gap formed between the end section of the roller and the running surface in a decentered position of the roller, in which the roller is adjusted from the centered basic position in the direction of the Abschlappung the tread at least approximately the same size as in FIG the centered basic position.
  • the Abschlappung the tread is formed up to a front side of the cam.
  • the tread has a central tread, which is designed at least approximately cylinder jacket-shaped and that the Abschlappung adjacent to the middle tread.
  • a roller shoe is provided, in which the roller is mounted, and that the roller shoe allows a certain displaceability of the roller perpendicular to a running direction of the roller on the tread.
  • the role is preferably configured substantially as a cylindrical roller.
  • the cam has a further Abschlappung on its tread and that the Abschlappung and further Abschlappung are configured symmetrically with respect to a centered basic position of the role.
  • the Abschlappung and further Abschlappung are designed so that the roller is guided in a centered basic position. Due to the Abschlappept on the cam thus the role is centered on its path. An oblique cam run-up of the roller is thus counteracted. As a result, a lateral start of the roller is prevented or at least avoided on both sides.
  • Fig. 1 shows a high pressure pump 1 in a schematic, axial sectional view according to an embodiment of the invention.
  • the high pressure pump 1 can be configured in particular as a radial or inline piston pump.
  • the high-pressure pump 1 is suitable as a fuel pump for fuel injection systems of air-compressing, self-igniting internal combustion engines.
  • a preferred use of the high pressure pump 1 is for a fuel injection system with a fuel rail, a so-called common rail that stores diesel fuel under high pressure.
  • the high-pressure pump 1 according to the invention is also suitable for other applications.
  • the high-pressure pump 1 has a multipart pump housing 2.
  • the pump housing 2 comprises a housing part 3 and a flange 4 connected to the housing part 3. Furthermore, a cylinder head 5 is provided, which is connected to the housing part 3.
  • a drive shaft 6 is arranged in the pump housing 2.
  • the drive shaft 6 includes a cam 7.
  • the cam 7 can also be configured as a multiple cam.

  • the high-pressure pump 1 has a pump assembly 15.
  • the high-pressure pump 1 may also have a plurality of pump assemblies.
  • the pump assembly 15 can be driven by means of the cam 7 of the drive shaft 6. If the high-pressure pump 1 has further pump assemblies, these may be driven by the cam 7 together with the pump assembly 15. It is also possible that at least one further cam is provided on the drive shaft 6, which serves according to the cam 7 for driving at least one pump assembly. Depending on the configuration, a radial or series piston pump can thereby be realized.
  • the housing part 3 of the pump housing 2 has a bore 16.
  • a projection 17 is formed, which projects into the bore 16 of the housing part 3.
  • the pump assembly 15 is provided in the region of the projection 17 and the bore 16.
  • the approach 17 has a cylinder bore 18 in which a pump piston 19 is guided.
  • the pump piston 19 limits a pump working chamber 20 in the cylinder bore 18.

  • the pump piston 19 is slidable along the axis 24, as illustrated by the double arrow 25.
  • the pump assembly 15 also has a hollow cylindrical plunger body 26 which is guided in the bore 16. An inserted into the plunger body 26 driving element 27 engages behind a collar 28 of the pump piston 19. Here, the driving element 27 is acted upon by a plunger spring 29 in the direction of the cam 7. During a movement of the plunger body 26 thus the pump piston 19 is taken.
  • a roller shoe 30 is also used.
  • the collar 28 of the pump piston 19 abuts against the roller shoe 30.
  • a roller 31 is mounted, which is designed as a roller 31.
  • the roller 31 is in this case at least substantially cylindrical. This results in an advantageous guidance of the roller 31 in the roller shoe 30.
  • the cam 7 has an end face 32, which faces the bearing point 9, and a further end face 33, which faces the bearing point 8.
  • the end faces 32, 33 are remote from each other.
  • the cam 7 has a running surface 34.
  • the roller 31 runs, for example, in a running direction 35 along the running surface 34.

  • a centered basic position of the roller 31 is given to the tread 34, in the Fig. 1 is shown.
  • the roller 31 rotates about its axis 37.
  • the configuration of the high-pressure pump 1 is below also with reference to the Fig. 2 described in further detail.
  • Fig. 2 shows the in Fig. 1 With II designated section of the high-pressure pump 1 of the embodiment, wherein the roller shoe 30, the roller 31 and parts of the cam 7 are shown.
  • the cam 7 has on its tread 34 a Abschlappung 40 and a further Abschlappung 41.
  • the Abschlappung 40 extends to the end face 32.
  • the further Abschlappung 41 extends to the other end face 33.
  • the Abschlappeptept 40, 41 adjoin on both sides of the central tread 36 of the tread 34 at. In this embodiment, therefore, the middle tread 36 extends together with the two Abschlappieux 40, 41 over the entire running surface 34 of the cam. 7
  • the Abschlappened 40, 41 are configured as convex Abschlappungen 40, 41. With respect to the at least approximately cylindrical roller 31 are formed by the Abschlappept 40, 41 small gaps 42, 43 between the roller 31 and the tread 34.
