Definitions

  • the present invention relates to a high-pressure piston pump for feeding fuel to an internal combustion engine.
  • the present invention relates to a high-pressure piston pump for feeding fuel to a common rail of an internal combustion diesel engine.
  • the above-identified type of high-pressure piston pumps generally comprises a pump housing; at least a piston reciprocated in a cylinder; a roller for reciprocating the piston; and a fuel suction valve to selectively let in low-pressure fuel from a fuel feeding duct in the cylinder when the piston is in the suction stage, and isolate the cylinder from the fuel feeding duct when the piston is the compression stage; the suction valve comprising a valve plate and a valve shutter cyclically impacting on the valve plate.
  • the high-pressure piston pump is made of a high number of components such as the piston, the suction valve shutter and a roller acting as a cam, which undergo high cyclic loads that may be either impacts or sliding frictions when they carry out their proper functions.
  • the pressure generated by the high-pressure piston pump reaches nowadays up to 2000 bar and it is foreseen for the next future a further increase of the fuel pressure in order to fulfil the new environmental legislation concerning the emissions of exhaust gases. Therefore, the above-mentioned cyclic loads are foreseen to stress even more severely the components of the high-pressure piston pump. It follows that the mentioned components can be rapidly worn out.
  • the above-mentioned components are made of steels, which are thermally treated so as to improve the desired properties in terms of stress and wear resistance.
  • a wear-resistant coating is applied to the surfaces of the piston, of the roller, and of the suction valve shutter.
  • the wear-resistant coating is applied only to those portions of the surfaces that are subjected to intense wear.
  • the application of the wear-resistant coating is still an expensive process that determines a high cost for the entire pump.
  • the shallow wear-resistant coating layer might delaminate, when impact loads occur.
  • a high-pressure piston pump for feeding fuel to an internal combustion engine, in particular a diesel engine;
  • the pump comprising a pump housing; at least a piston reciprocated in a cylinder; a roller for reciprocating the piston; and a fuel suction valve to selectively let in low-pressure fuel from a fuel feeding duct in the cylinder when the piston is in the suction stage, and isolate the cylinder from the fuel feeding duct when the piston is in the compression stage;
  • the suction valve comprising a valve plate and a valve shutter cyclically impacting on the valve plate;
  • the pump being characterized in that the valve shutter is made of a material selected in the group of the cemented carbides.
  • cemented carbides further to the known property of being wear-resistant to frictions, have proven to be resistant even to impacts.
  • valve shutter comprises and shutting body impacting on the valve plate and a shank sliding inside the valve plate; the valve shutter being made as a single body of said material.
  • reference numeral 1 indicates as a whole a high-pressure radial piston pump suitable for receiving fuel from a low-pressure pump (not shown) and for compressing the fuel to pressures higher than 2200 bars for feeding the fuel to a common rail of an internal combustion Diesel-engine (not shown in the enclosed figures).
  • Pump 1 comprises a pump housing 2 essentially made of a block of metallic material, in which three cylinders 3 (only one shown in figure 1), three fuel feeding duct 4, and three fuel delivery ducts 5 are machined. Pump 1 comprises for each cylinder 3 a piston 6; a suction valve 7 arranged along the feeding duct 4; and a delivery valve 8 arranged along the delivery duct 5.
  • the pump 1 comprises a camshaft 9, which has a cylindrical cam 10, and rotates about a longitudinal axis A1 perpendicular to the cylinders 3; a cylindrical chamber 11 for housing cam 10; a roller 12, which is coupled to cam 10 and is revolved along a circular path about longitudinal axis A1 by cam 10.
  • cam 10 has an axis A2, which is parallel to axis A1 and axially offset with respect to A1.
  • Roller 12 is fitted to cam 10 that has a cylindrical portion; and comprises an outer face having three flat surfaces 13, each of which faces a corresponding piston 6, and an inner cylindrical face in direct contact with a cylindrical outer face of the cylindrical portion of the cam 10.
  • the rotation of the camshaft 9 about longitudinal axis A1 determines the revolution of the roller 12 about longitudinal axis A1 and the rotation of the roller 12 about axis A2 of cam 10.
  • Roller 12 during revolution along the circular path keeps parallel to itself and determines the strokes of the pistons 6.
  • each piston 6 extends along an axis A3 and is made as a single body.
  • Each piston 6 comprises a cylindrical body 14 and a foot 15, which has substantially a shape of two superimposed discs 16 and 17 larger than the cylindrical body 14 and an end protrusion 18 defining a surface 19.
  • superimposed discs 16 and 17 define the seat for an end of a helical spring 20 for biasing the piston 6 towards roller 12.
  • the helical spring 20 is housed inside an annular seat machined in the pump housing 2 and determines the back stroke of the piston 6.
  • Pump 1 further comprises for each piston 6 a bucket tappet 21 that comprises a cylindrical wall 22 arranged about the helical spring 20 and a base wall 23 arranged between the piston 6 and the roller 12.
  • a bucket tappet 21 that comprises a cylindrical wall 22 arranged about the helical spring 20 and a base wall 23 arranged between the piston 6 and the roller 12.
  • the lateral wall 22 is reciprocated in a seat machined in the pump housing 2, whereas the base wall 23 slides along the flat surface 13 of the roller 12.
  • Each suction valve 7 comprises a valve plate 24; a shutter 25; a helical spring 26 for biasing the shutter 25 against the valve plate 24 and a screw plug 27 for fastening the valve plate 24 in a seat machined in the pump housing 2.
  • the suction valve 7 comprises a ring 28 pressed in and welded to the shutter 25.
  • the valve plate 24 is ringshaped and has a portion 29 of the fuel feeding duct 4 machined in it and a truncated cone-shaped surface 30 defining a resting seat for the shutter 25.
  • the shutter 25 has a shutting body 31 and a shank 32, which is guided by a seat matching with the shank 29 and machined in the valve plate 24; and is pressed into and welded to the ring 28.
  • Helical spring 26 is compressed between the valve plate 24 and the ring 28 so as to bias the shutting body 31 against the valve plate 24.
  • the shutting body 31 is provided with a truncated cone-shaped surface 33 matching with the truncated cone-shaped surface 30 of the valve plate 24 so as to close (when in closed position) the suction valve 7 in fluid-tight manner.
  • each suction valve 7 opens to let in low-pressure fuel in the cylinder 3 from fuel delivery duct 4, and successively closes to isolate the cylinder 3 from the fuel feeding duct 4 and to compress the fuel by the piston 6.
  • the shutter 25 impacts against the valve plate 24 and is further pressed by the fuel compressed in the cylinder 3 against the valve plate 24.
  • the ring 28 is omitted and the helical spring 26 is compressed between the piston 6 and the shutting body 31.
  • the suction valve shutter 25 is made as a single body of a material selected in the group of the cemented carbides.

  • the piston 6 is made as single body of cemented carbides.
  • roller 12 The selected materials have proven to be suitable to make an entire component of the pump 1 even with a complex shape. Since roller 12 is made of cemented carbides and highly wear-resistant to friction, the roller 12 can be coupled to cam 10 without bearing.
  • the sintered cemented carbides have proven to be compatible with the material of the pump housing that is selected among the alloys 20MnCrS5, 23MnCrMo5 and 100Cr 6.
