Definitions
- the invention relates to bucket tappets for an internal combustion engine, that explained in the preamble of claim 1 Art.
- DE-OS 22 09 926 is a tappet for an internal combustion engine, that explained in the preamble of claim 1 kind known.
- tappet that is Pot-shaped plunger housing molded from a plastic material in which a metallic inner floor is inserted, its underside with the valve stem of a gas exchange control valve interacts and its top with interposition a game compensation tile with a Cam of a camshaft interacts.
- the lash adjuster plate inserted in the tappet housing can with its edges with the rather hard Plastic material interact with its bottom however, it is metallic on the metallic inner floor on.
- DE-AS 26 43 546 is a tappet for an internal combustion engine known, in which the inserted game compensation tiles between the inner bottom of the tappet housing and the valve stem of the gas exchange control valve with interposition a strip of calibrated, elastic Strip material (steel strip) can be arranged.
- the elastic Tape material is not a measure to put between the pestle bottom and rattling noises occurring on the game compensation tile to prevent.
- a bucket tappet for an internal combustion engine which is a disc-shaped elastomer insert between the game compensation plate and the top of the plunger bottom is arranged.
- This known embodiment has the disadvantage that the assembly of the Arrangement is more complex due to the large number of items to be arranged.
- the object of the invention is to provide a tappet for a Internal combustion engine, which in the preamble of claim 1 explained type to improve such that with little additional Effort the rattling noises occurring on the tappet avoided or at least strongly dampened.
- this object is achieved by a tappet for an internal combustion engine, which in the preamble of claim 1 explained type in the characterizing part of patent claim 1 features applied will.
- Match compensation tile at least on its outer circumference is provided with a coating of elastomeric material, are transferred from the cam to the game compensation tile radial forces that cause the game compensation tile to strike with its edges in the shot on Guide the outside floor, dampened with noise.
- insoluble is particularly advantageous Connect the elastomeric material to the respective component, the adjustment plate or the tappet if implemented in the case of a cup-shaped Tappet housing made of plastic material, the damping ribs, webs or Projections and teeth are made of uniform material from the housing material.
- FIGS. 1 to 4 for a Internal combustion engine consist of the tappets 1 and 1 ', respectively from a tappet housing 2 or 2 ', which is essentially from a cylindrical shaft part 3 or 3 'and a ram bottom 4 or 4 '.
- the game compensation tiles 6, 6 ', 6' 'and 6' '' take part the cam 7 of a camshaft 8 together, the axial and radial Forces with radial and axial play in the Admission 5 or 5 'inserted game compensation plate.
- the plunger base 4 or 4 ' has an upper side 9 or 9 'on that with the game compensation tiles 6, 6', 6 '' and 6 '' 'cooperates and an underside 10 on which with the Valve stem 11 of a gas exchange control valve (not shown) cooperates.
- Fig. 3 the top 9 'of the recesses differs 5 'compared to the explanations in FIGS. 1 and 2 through an integrated annular groove 14, which one between the Game compensation plate 6 '' and the plunger base 4 'inserted O-ring 15 picks up and centers.
- Fig. 4 acts instead of the O-ring in Fig. 3 to the Match compensation tile 6 '' 'vulcanized ring bead 16 made of elastomeric material together with the annular groove 14.
- the one used to coat the game compensation tiles Elastomer can be an elastomer from the group of nylon materials be wear-resistant and heat and oil resistant are and still have a certain damping capacity have.
- the simplest embodiment of the invention is here 2 where that for coating the outer circumference and to coat the underside of the game compensation tile 6 'applied elastomeric material e.g. by evenly spraying on the elastomeric material the exposed areas of what is passing on a conveyor Match compensation tiles are applied can.
- the thickness of the coating must be made of elastomer Material, its modulus of elasticity and other mechanical Properties precisely tailored to the requirements within be matched to an internal combustion engine.
- the elastomeric coating must have a minimum thickness, which on the one hand ensures their noise-damping function, which, on the other hand, does not result in any collision with regard to the spring forces acting on the gas exchange control valve leads.
- the elastomeric coating also be applied only in the recess of the tappet and the game compensation tile remains in its normal state untreated condition.
- Ring webs 18 are formed and are axially on the inner circumference extending resilient ribs 19 formed, the a game compensation plate 20 made of steel and in axial and resiliently support the radial direction.
