Definitions

  • the invention relates to a roller tappet arrangement to transmit a driving force from a driving camshaft to a high pressure generating device of a high pressure fuel pump. Further, the invention relates to an arrangement of a high pressure fuel pump to pressurize a fuel in a fuel injection system of a combustion engine and an engine block of a combustion engine. Moreover, the invention relates to an engine box of the combustion engine comprising this arrangement.
  • roller tappet arrangement The lubrication of a roller tappet arrangement can be quite complex, in particular if the roller tappet arrangement is a part of a so-called plug-in-pump which does not have its own housing, but is directly inserted into a receiving bore of an engine block, such that the engine block forms the housing of the pump.
  • JP H02 144 601 U describes a roller tappet to drivingly connect a camshaft and a piston, the roller tappet having a tappet body being guided by a guide pin in a tappet fitting hole, wherein the guide pin transmits a lubricant into the inner part of the tappet body.
  • the tappet body further comprises a through hole at its bottom end such that the lubricant can flow to a roller in order to lubricate the roller.
  • JPH02215966 A discloses another roller tappet arrangement.
  • Object of the invention is to provide an improved lubrication solution for a roller tappet arrangement of a high pressure fuel pump.
  • a roller tappet arrangement to transmit a driving force from a driving camshaft to a high pressure generating device of a high pressure fuel pump comprises a roller tappet body to be moved along a moving axis in a receiving bore to receive the roller tappet body.
  • the roller tappet body has a tappet wall surrounding a receptacle for a roller.
  • the arrangement comprises a roller being arranged in the receptacle to rollingly contact the driving camshaft and a guide pin extending through the tappet wall into the receptacle to guide the roller tappet body in a defined orientation on the camshaft.
  • the guide pin comprises a lubrication bore to guide a lubricant into the receptacle.
  • the tappet wall comprises a slot to engage with a receptacle end portion of the guide pin, the slot extending parallel to the moving axis of the roller tappet body. Hence, with this slot the roller tappet body is guided during its movement along the moving axis by the receptacle end portion of the guide pin
  • a guide pin is plugged into a housing surrounding the roller tappet arrangement, e.g. the engine block of a combustion engine, to provide a preferred correct orientation of the roller tappet body on a surface of the camshaft.
  • the guide pin now has two functions, first to provide the correct orientation of the roller tappet body on the camshaft, and second to provide a built-in-lubrication circuit which results in a correct lubrication inside the roller tappet body. Therefore, a separate lubrication jet line which was provided in previous solutions can be avoided. Hence, the lubrication of the roller tappet body is less complex. Moreover, even with the less complex arrangement of the lubrication of the roller tappet body a more correct lubrication of elements of the roller tappet body can be attained compared to the lubrication of splash oil as the lubricant is guided in a directive manner into the inside, namely the receptacle, of the roller tappet body.
  • the lubrication bore in the guide pin has the same length as the guide pin and therefore runs preferably from a first end of the guide pin to a second end of the guide pin.
  • the lubrication of the elements in the receptacle of the roller tappet arrangement is critical.
  • the lubrication of the outer surface of the roller tappet body, which is in direct contact with the receiving bore via a clearance is - as in the solutions before - provided by splash oil crawling up the clearance from the camshaft chamber. This splash oil lubricant is sufficient to lubricate the outer surface of the roller tappet body during its movement.
  • the guide pin is arranged in the tappet wall such that a jet of the lubricant escaping the lubrication bore into the receptacle can strike a holding area where the roller is held in the roller tappet body.
  • the guide pin can also be arranged in the tappet wall such that the jet of the lubricant can strike a roller surface of the roller.
  • the guide pin can also be arranged such that the jet of the lubricant can strike a contact area where a roller is in contact with the driving camshaft.
  • a longitudinal axis of the guide pin is arranged perpendicular to the moving axis of the roller tappet body.
  • the longitudinal axis of the guide pin is arranged in an angle of between 10° to 85° to the moving axis of the roller tappet body.
  • the guide pin is arranged in an inclined manner in the tappet wall and is preferably directed to the contact area where the roller is in contact with the driving camshaft.
  • the lubrication bore comprises at least two branches exiting the guide pin into the receptacle.
  • these two branches are arranged with an angle to each other such that they are directed into different directions in the receptacle.
  • a first branch exits the guide pin such that the lubricant can strike the contact area of the roller surface and the surface of the camshaft.
  • a second branch exits the guide pin such that the lubricant can strike only the roller surface.
  • a branch which exits the guide pin such that the lubricant can strike a holding area where the roller is held in the roller tappet body.
  • three branches each of which is directed to any of the three above mentioned directions.
  • the lubrication bore is arranged to be connected to an engine lubrication circuit of a combustion engine. Therefore, an own lubrication circuit to lubricate only the roller tappet arrangement can be avoided and a synergistic effect can be attained.
  • the high pressure fuel pump is formed as a plug-in-pump and comprises the roller tappet arrangement as described above.
  • the engine block comprises a receiving bore to receive the high pressure fuel pump with its roller tappet arrangement and comprises further a pin bore connecting an outside area of the engine block with the receiving bore, wherein the guide pin is secured in the pin bore via a screw-fit-connection or via a press-fit-connection.
  • a plug-in-pump arrangement has the advantage that an own housing of the pump can be omitted making the pump more light-weight and smaller which are desirable characteristics if the space to insert a high pressure fuel pump into a combustion engine is limited.
  • an engine block provides a housing for the plug-in-pump by comprising a receiving bore into which the plug-in-pump is inserted. Therefore, the roller tappet arrangement is moving in this receiving bore.
  • this arrangement it is possible to provide as driving camshaft a camshaft of the combustion engine such that the plug-in-pump does not need its own driving camshaft. This also is advantageous as it is more space saving.
  • the guide pin is provided which is arranged in the engine block in a specially adapted pin bore.
  • This pin bore is extending from the receiving bore where the plug-in-pump is inserted into to the outside area of the engine block such that it is possible to insert the guide pin after installment of the plug-in-pump in the receiving bore.
  • a screw-fit-connection or a press-fit-connection can be used.
  • the guide pin is extending from the receiving bore into the pin bore wherein a separate plug device is extending from the outside area into the pin bore to seal the pin bore.
  • the plug device and the guide pin are arranged in a distance to each other to provide an orifice area for a connection with an engine lubrication circuit of the combustion engine. Due to this orifice area there is a complete design freedom to provide an opening in a wall of the pin wall where a connection to the engine lubrication circuit can be provided.
  • the guide pin is extending from the receiving bore to the outside area and integrally comprises a plug device and a connection nipple to be connected with an engine lubrication circuit of the combustion engine.
  • the lubrication bore extends from the receiving bore to the outside area through the plug device and the connection nipple. Therefore, the connection with the engine lubrication circuit can be provided outside the engine block which can be easier to provide.
  • the lubrication bore forms the only lubrication path in the engine block to guide a lubricant into the receiving bore. Therefore, additional lubricant pathes in the engine block can be avoided which makes the arrangement more easier to manufacture.
  • An engine box of a combustion engine comprises an arrangement of a high pressure fuel pump and an engine block as described above and a driving camshaft, wherein the camshaft is in permanent contact with the roller of the roller tappet arrangement to drive the roller tappet body along the moving axis.
  • the camshaft can e.g. be a camshaft or a crankshaft of the combustion engine.
  • Fig. 1 shows a longitudinal sectional view of an arrangement 10 of a high pressure fuel pump 12 which is arranged in an engine block 14 of a combustion engine.
  • the engine block 14 with the high pressure fuel pump 12 is arranged in an engine box 16 of the combustion engine, where also a camshaft 18 is located which can drive the high pressure fuel pump 12.
  • the high pressure fuel pump 12 does not comprise an own housing, but is arranged in a receiving bore 20 in the engine block 14 and is therefore constituted as a plug-in pump 22.
  • the high pressure fuel pump 12 comprises a high pressure generating device 24 with a pressurizing room 26 and a piston 28 which carries out a translational movement to minimize the volume of the pressurizing room 26 and thereby pressurize a fuel 30 with which the pressurizing room 26 is filled.
  • a roller tappet arrangement 32 is in contact with a cam area 34 of the camshaft 18 and due to this contact during a rotational movement of the camshaft 18 around a camshaft axis 36 the roller tappet arrangement 32 moves in the receiving bore 20 along a moving axis 38.
  • the piston 28 Via a spring 40 which biases the piston 38 onto the roller tappet arrangement 32 the piston 28 is in permanent contact with the roller tappet arrangement 32 and also moves along the moving axis 38. Hence, the roller tappet arrangement 32 transfers a driving force from the cam area 34 onto the piston 28.
  • a guide pin 42 is provided which extends through a pin bore 44 in the engine block 14 from an outside area 46 to the receiving bore 20.

  • the tappet wall 50 forms a hollow space which constitutes a receptacle 54 in which a roller 56 is provided. This roller 56 is in direct contact with a camshaft surface 58.
  • the guide pin 42 extends through the tappet wall 50 into the receptacle 54 and comprises a lubrication bore 60 in its inside through which a lubricant 62 can be guided into the receptacle 54.
  • the guide pin 42 is arranged in the tappet wall 50 and the engine block 14 such that a longitudinal axis 64 of the guide pin 42 is arranged perpendicular to the moving axis 38 of the roller tappet arrangement 32. Therefore, the lubricant 62 escaping the lubrication bore 60 strikes a roller surface 66 of the roller 56.
  • the guide pin 42 extending from the receiving bore 20 to the outside area 46 integrally comprises a plug device 68 and a connection nipple 70.
  • the plug device 68 the guide pin 42 is secured in the pin bore 44 and via the connection nipple 70 the lubrication bore 60 can be connected with a lubrication circuit 72 of the engine.
  • the lubrication bore 60 extends fully through the guide pin 52, therefore also through the plug device 68 and the connection nipple 70 to the outside area 46.
  • the guide pin 42 is secured in the pin bore 44 via a press-fit connection 74.
  • Fig. 3 shows a longitudinal sectional view of a second embodiment of the roller tappet arrangement 32 and guide pin 42 in the engine block 14 of Fig. 1 .
  • the guide pin 42 is also arranged such that its longitudinal axis 64 is arranged perpendicular to the moving axis 38, but different to the embodiment shown in Fig. 2 , the guide pin 42 is extending from the receiving bore 20 into the pin bore 44 but does not fully extend through the pin bore 44.
  • the plug device 68 is a separate device which is extending from the outside area 46 into the pin bore 44. Inside the pin bore 44 the guide pin 42 and the plug device 68 are arranged in a distance 76 to each other such that an orifice area 78 is provided.
  • the plug device 68 is secured in the pin bore 44 via screw-fit connection 81.
  • Fig. 4 shows an enlarged view of the region around the orifice area 78 of Fig. 3 .
  • an orifice 80 of the lubrication circuit 72 of the engine opens into the orifice area 78 between the guide pin 42 and the plug device 68.
  • the orifice area 78 and also the lubrication bore 60 in the guide pin 42 are connected to the lubrication circuit 72.
  • Fig. 5 shows a longitudinal sectional view of a third embodiment of the roller tappet arrangement 32 and guide pin 42.
  • the guide pin 42 - formed similar to the guide pin 42 of Fig. 2 with an integrally formed plug device 68 and connection nipple 70 - is arranged such that its longitudinal axis 64 is arranged in an angle ⁇ relative to the moving axis 38.
  • the angle alpha ⁇ lies in the region of 10° to 85°.
  • the lubricant 62 escaping the lubrication bore 60 can strike either a contact area 82 where the roller 56 is in contact with the camshaft 18 or a holding area 84 where the roller 56 is held in the roller tappet body 48.
