Definitions

  • the invention relates to a tappet of a valve train of an internal combustion engine, with a closed on one side by a bottom hollow cylindrical Shirt, which ground on its outer face a tread for a cam and at its inner end face a centric system for a gas exchange valve.
  • Such a tappet is considered from the considered generic JP 6-17609 (A) previously known. Its bottom has on its inner and outer Face, except for the system for the gas exchange valve, a roughly same, flat course. Due to this course, the soil must be relatively massive be formed so that the bucket tappets the dynamic u. a. Beta EVENTS grown during his operation.
  • bucket tappet relative to the diameter must be trained to a sufficient emigration area to guarantee the cam on the outer face.
  • the object of the invention is therefore to provide a bucket tappet of the known type in which eliminates the cited disadvantages by simple means are.
  • this object is achieved in that the inner end face of the floor has a radially extending, planar web, between whose edges the plant is symmetrically positioned, extending from each Edge a roof-like from the ground away beveled leg to an inside of the shirt, which legs are axially symmetric opposite.
  • the plunger as it is the subject of a subclaim is provided with means for preventing rotation and if its Ground at the same time in the direction of emigration of the cam seen a has cylindrical course.
  • the tappet Due to the cylindrical course can, with guaranteed emigration area for the cam on the outer face at the bottom, the diameter the tappets are reduced. It is as anti-rotation according to another subclaim, for example, a shirt in the tappet arranged roll needle provided which the shirt radially outward surmounted and when installing the bucket tappet thus in a longitudinal groove of a Mounting hole in the cylinder head or similar surrounding construction runs. Possibly. the bucket tappet can also be designed self-centering.
  • the system for the gas exchange valve on the Bridge to represent frustoconical or kidney segmental survey.
  • a defined contact surface which may also be specially protected against wear can be formed, created.
  • the Plant height-variable for the assembly process kept at the engine manufacturer become.
  • kidney segment-like or truncated cone-like elevation on the bridge opens up to the skilled person at this point even more embodiments, like purely cylindrical etc.
  • the plant as a plate-like or similarly trained indentation to portray in the dock.
  • the roof-like beveled thighs can indeed towards the ground seen as “solid material”, conceivable and intended, however also, this as a thin-walled and projecting from the inner end face of the soil Form ribs. Because of this measure is possibly another Contribution towards lightweight construction and lowering of the oscillating valve train masses done.
  • roof-like beveled legs proposed. These can, for example, concave or convex curved run or have a substantially planar extension. The expert is at this point by the familiar calculation and design methods find the appropriate shape of the legs for his application.
  • the figures disclose a bucket tappet 1 of a valve train of an internal combustion engine.
  • This consists of a on one side by a bottom. 2 closed hollow cylindrical shirt 3.
  • the bottom 2 has an outer end face 4.
  • This is designed as a contact surface 5 for a cam, not shown.
  • the contact surface 5 is in an emigration A of the Cam seen to have cylindrical course.
  • a recess 14 is provided in the shirt 3 .
  • Recess 14 extends a not shown in detail means 13a for preventing rotation. This can for example be pressed into the recess 14 Roller needle be that radially protrudes slightly beyond the shirt 3 and when installed the bucket tappet 1 in its corresponding receptacle in the cylinder head in one there applied longitudinal groove runs.
  • the legs 11, 12, starting from their edges 9, 10, in Direction to shirt 3 also be shown tapering to the bottom 2.
