Definitions

  • the invention relates to a plunger, suitable for either a high-pressure fuel pump or a valve train of a quality or quantity-controlled internal combustion engine, with a housing whose cam or eccentric start serving drive side is immanent a roller or sliding surface, wherein its an abutment of a ram follower serving output side an underside of an inner shell of the housing projecting through the bridge piece, wherein in a window of the housing has an outer shell superior rotation, which is formed from a radial extension of the bridge piece.
  • Such a plunger here for the lifting operation of a pump piston of a fuel pump, goes out of the DE 10 2006 057 246 A1 out.
  • a rotation for the housing is a radial extension of its bridge piece, which projects through a window of the housing (s. Fig. 1a - 1c ).
  • the bridge piece is held in the direction of the output side on a ring element, sitting on circumferentially distributed, emanating from the inner shell of the housing lugs.
  • a bucket tappet with hydraulic lash adjuster is out of the DE-42 09 440 A1 known.
  • the plunger housing with a bottom, a sleeve and an inner guide sleeve to be made of ceramic material.
  • a cover is used, which is fixed to at least one Ausulstung on the inside of the sleeve.
  • the cover also has a horizontal projection which projects into a slot of the sleeve. The horizontal approach surpasses the slot only slightly.
  • the fact that the cover of metallic material - in contrast to the ceramic material of the bucket tappet - is made, the cover fits or the horizontal approach particularly well the diameter increase of the bore of the cylinder head in the event of heating. It follows that the horizontal approach and its dimension does not constitute an anti-rotation but are provided only for clearance compensation of the bucket tappet in its bore due to thermal expansion.
  • valve module which consists of a valve with valve disc and springs and a tappet with a flat bottom and a sleeve.
  • a clearance compensation element is installed, which is held by means of a sealing bellows in the interior of the bucket tappet, wherein the edge of the sealing bellows is fixed at the transition between the bottom and the sleeve in the bucket tappet.
  • the U.S. 5,379,730 describes a bucket tappet with a flat bottom and a sleeve in which a hydraulic valve clearance compensation element are installed should, which is held by a metal cylinder inside the tappet.
  • the sheet metal cylinder is attached to the sleeve after insertion into the tappets by a rolling process.
  • To manufacture the Rollierwulstes in the metal cylinder and the sleeve is an inner tool 47 and an outer tool 45.
  • no projections, notches or the like are provided. The fixation takes place only later by the rolling process.
  • the tappet also has no anti-rotation.
  • the object of the invention is therefore to provide a plunger of the aforementioned type, in which the disadvantages listed are eliminated.
  • this object is achieved in that on the inner surface of the plunger, only at a window diametrically opposite portion, a produced by a stamping stamping process, integrally connected projection extends in a wedge-like manner towards the drive side, wherein the existing steel sheet bridge piece, with its the radial extension diametrically opposite section, is snapped over the projection and with an edge region whose bottom is on this.
  • the aforementioned plunger which is proposed as a roller or sliding plunger, for example, can be actuated by a cam on its drive side, the front side of a camshaft of a valve train of the internal combustion engine sits (pump plunger).
  • pump plunger the front side of a camshaft of a valve train of the internal combustion engine sits
  • the impact-generating means to any shaft of the internal combustion engine, such as a balancing or crankshaft (pump tappet).
  • this plunger can communicate with a cam of an overhead or underlying camshaft.
  • the bridge piece is very simple. Thus, the production costs in mass production can be reduced.
  • the bridge piece is performed with its preferably one piece extending thereon radial extension on the output side end of the housing and inserted with its radial extension in the respective window. Subsequently, a snapping / locking of the bridge piece takes place with its radial extension diametrically opposite side over the protruding from the inner surface of the housing projection and an application to lower sides of diametrically opposed in the housing flax.
  • the aforementioned snap-in projection can be generated, for example, by a simple stamped-stamping process.
  • a separate snap-in nose can be applied.
  • the latter flax have stiffening function and serve to arrange a bolt, on which bolt a sliding or roller bearing roller runs as a contact partner for the cam or eccentric.
  • the bridge piece with the finger-like approach to the representation of the rotation can be stamped from sheet metal material, embossed and bent. Possibly. Alternative materials such as plastics or composites are conceivable and intended. Topsides of the bridge piece, which bear against undersides of the flax, expediently follow the contour of the last-mentioned undersides.
  • the bridge piece may be slightly cylindrical, which also contributes to stiffening.
  • the protruding from the bridge piece anti-rotation can, according to a further proposal of the invention, be subjected to further treatment on its front side.
  • Another proposal relates to attaching a separate component such as a pin or a pipe section in the end face of the radial extension of the bridge piece.
  • the latter components can be connected, for example by pressing, soldering, welding, etc. with the bridge piece and also increase the guide length in the groove during installation.
  • a further subclaim finally refers to the fact that the housing is made of a low-cost lightweight construction material such as sheet steel, for example by deep drawing. Thus, another contribution is made in reducing the costs.
  • the plunger 1 here as a counter-rotor for a cam of a high-pressure fuel pump.
  • the plunger 1 consists of a substantially cylindrical housing made of thin-walled sheet steel, with a driven side 3 and a drive side 7.
  • the housing 2 is limited on its drive side 7 by a drive-side end 17. It has two reaching to this forehead 17 and diametrically opposite flax 18.
  • a bearing eye 19 is applied in each flat 18.
  • FIGS. 1, 2 reveal, sitting in the bearing lugs 19 at the end a bolt 20 on which a roller bearing roller 8 extends.
  • the roller 8 communicates with a not shown cam of a fuel pump.
  • an inner jacket 5 of the housing 2 is penetrated by a bridge piece 6.
  • the bridge piece 6 is formed as a thin-walled sheet-metal component and has a finger-like radial extension 12 for representing a rotation 11.
  • the housing 2 has a window 9 through which the radial extension 12 of the bridge piece 6 protrudes.
  • the bridge piece 6 is located on the one hand in the direction of the drive-side end 17 on lower sides 16 of the flax 18.
  • the bridge piece 6 is snapped behind a protruding from the inner shell 5 of the housing 2 projection 15 with an edge portion 14 of the radial extension 12 opposite portion 13.
  • the at least one projection 15 is represented for example by a punched / embossed.
  • a cost effective plunger 1 is created by the one-piece connection of the radial extension 12 with the bridge piece 6 to represent the rotation 11 and by the same simple axial fixation of the bridge piece 6 on the projection 15 and on the undersides 16 of the flax 18 , Through the window engagement of the bridge piece 6 and its storage on the projection 15 a very simple captive for the bridge piece 6 is created.
  • the plunger 1 is reduced in terms of its number of components compared to plungers according to the prior art.
  • FIGS. 4 to 7 show special embodiments of an outer end 21 of the radial extension 12. So can after FIG. 4 the outer end 21 may be upset, for example, so that a larger guide length is given. According to the embodiment according to FIG. 5 it is provided to attach a separate insert part 23 to the outer end 21. Also, according to FIG. 6 the contact surface with the guide groove in the surrounding material by an ironing or after FIG. 7 be increased by bending.
