Definitions
- the invention relates to a plunger, either for a Kraftstoffh ch or duck pump for a valve train of a quality or quantity-controlled internal combustion engine, with a housing whose cam or eccentric drive end serving a roller or sliding surface immanent, wherein its a plant of a ram follower serving Output side is located on an underside of an inner jacket of the housing projecting 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, it is apparent from DE 10 2006 057 246 A1.
- a radial extension of its bridge piece which protrudes through a window of the housing (see Fig. 1 a - 1 c), serves as anti-rotation device for its housing.
- 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.
- 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 section diametrically opposed to the radial extension, over which projection is snapped and with an edge region of its bottom lying on top of it.
- the abovementioned plunger which is proposed as a roller or sliding plunger, can be actuated, for example, by a cam on its drive side, which sits on the end face of a camshaft of a valve drive of the internal combustion engine (pump plunger).
- pump plunger a cam on its drive side
- 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 bridging piece is guided, with its preferably radially in one piece extending thereon, radially over the output-side end of the housing and inserted with its radial extension into 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 dependent claim 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 technology.
- a low-cost lightweight construction material such as sheet steel
- Figure 1 shows the plunger according to the invention in an exploded view
- Figure 2 shows the plunger of Figure 1 in the assembly
- Figure 3 is an enlarged view of the inner shell of the plunger in the region of the projection
- 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 flat flanges 18 which reach up to this end 17 and are diametrically opposed. In each flat 18, a bearing eye 19 is applied.
- Figures 1, 2 reveal, sits 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 1 1.
- 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 region 14 of the radial extension 12 opposite portion 13.
- the at least one projection 15 is represented for example by a punched / embossed. It is obvious that by the one-piece connection of the radial extension 12 with the B back piece 6 for showing the rotation 1 1 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 a inexpensive ram 1 is created. 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. In addition, 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.
- the outer end 21 can be upset, for example, so that a larger guide length is provided.
- it is provided to fasten a separate insert part 23 to the outer end 21.
- the contact surface to the guide groove in the surrounding material by an ironing o- of Figure 7 by Anwinkein be increased.
