Definitions

  • the invention relates to an automatically hydraulically adjusting valve tappet according to the preamble of claim 1.
  • the invention has for its object to eliminate this disadvantage with simple constructive measures and in particular hardly cause additional costs and to achieve a permanent and independent of the floor deflection of the sleeve against the oil reservoir.
  • the invention solves this problem by the features specified in the characterizing part of claim 1. This ensures that the point at which the connection between the sleeve on the one hand and the cup-shaped housing takes place on the other hand is at a point which is unaffected by the floor deflections during operation.
  • the flange is expediently provided on its radially outer edge with a short cylindrical collar which faces axially away from the ground and which fits snugly in the bore of the hollow cylindrical wall.
  • a short cylindrical collar which faces axially away from the ground and which fits snugly in the bore of the hollow cylindrical wall.
  • the radially outward flange starting from the sleeve bear against the bottom of the cup-shaped housing, or to arrange it at a short distance from the floor, in order to ensure that any influence of the floor deflections on the flange and thus switch off to the weld seam that may be provided.
  • the flange can be slightly inclined so that it is only in its radially outermost region in contact with the inner surface of the floor. But it can also be supported on a shoulder of the hollow cylindrical wall so that it has no contact with the inner surface of the bottom. It is also possible to design the sleeve so that its end facing away from the ground is supported on the disk part. This creates a clamp connection that provides a secure hold for the sleeve and the flange connected to it.
  • the invention can also be used with advantage in a known valve tappet in which a cylinder jacket bears against the bore of the hollow cylindrical wall, which is attached to the wall in a liquid-tight manner at its end facing away from the floor and which delimits a longitudinal channel with the wall at at least one circumferential point , which is connected to an oil feed hole at its end facing away from the floor, and which opens into the oil reservoir at its bottom end.
  • a tappet it is expedient to design and dimension the cylinder jacket in such a way that it supports the cylindrical collar of the radial flange with its bottom end face.
  • the plunger shown consists of the cup-shaped housing 1, which consists of the hollow cylindrical wall 2 and the bottom 3, which is integral therewith.
  • this housing an inner part 4 is arranged, which is formed from the disc part 5 and the cylindrical guide sleeve 6.
  • the disk part 5 lies against the circumferential groove 8 formed in the hollow cylindrical wall and, on the other hand, is covered by the bead 9 formed out of the hollow cylindrical wall.
  • the hydraulic lash adjuster 10 is mounted, which consists of the outer piston 11, which is slidably guided in the guide sleeve 6, and on the other hand, in turn, slidably and tightly receives the inner piston 12.
  • This has at its end facing the bottom 3 a central oil storage space 13, which is in fluid communication with an annular space 16 by means of the recess 14 in the inner surface 15 of the bottom 3, which is delimited by the inner piston 12 on the one hand and a sleeve 17 on the other, which starting from the bottom 3, it extends over the cylindrical guide sleeve 6 into the vicinity of the disk part 5.
  • the sleeve 17 is dimensioned such that it overlaps the guide sleeve 6 on the outside with its bore and has at least one circumferential point with a longitudinally extending groove-shaped formation 18 which, together with the guide sleeve 6, delimits a longitudinal channel 19 via which oil from the outside annular oil storage space 20 in the annular space 16 and from there can finally get into the central oil storage space 13. From there, the oil is fed into the high-pressure oil chamber 22 in a known manner via the check valve 21.
  • the sleeve 17 is connected to the housing 1 in that at its end adjacent to the base 3 it has a slightly inclined flange 23 which extends outwards to the bore of the hollow cylindrical wall 2 and there in a short, passes axially away from the bottom 3 cylindrical collar 24 which fits snugly in the bore of the hollow cylindrical wall 2 and thereby creates a durable connection. If it is deemed necessary, the cylindrical collar 24 can additionally be welded to the bore of the wall 2 at its free end.
  • Figure 2 differs from Figure 1 in that the flange 23 is supported against a shoulder 25 of the hollow cylindrical wall 2 so that it has no contact with the inner surface 15 of the bottom 3. At the same time, the sleeve 17 is supported with its end facing away from the bottom 3 on the disk part 5, so that a firm clamping connection is provided.
  • the ring stamp 31 is shown in its position before the material deformation of the wall 2, while the right half shows the ring stamp 31 in the position after the bead 30 has been shaped out of the wall 2.
  • retaining lugs for the sleeve 17 can also be formed out of the wall 2 at individual circumferential locations.
  • the ring stamp 31 has projections, the outer edges of which lie on a diameter that is larger than the diameter of the collar 24.
  • a cylinder jacket 26 adjoins the radially outer edge of the disk part 5, which lies against the bore of the hollow cylindrical wall 2 and which in the example shown is produced in one piece with the inner part 4.
  • this cylinder jacket 26, together with the wall 2 delimits a longitudinal channel 27 which is connected to an oil feed bore 28 at its end facing away from the bottom 3 and which opens into the oil reservoir 20 at its bottom end.
  • the cylindrical collar 24 of the flange 23 is supported on the bottom end face of the cylinder jacket 26 and is therefore sufficiently fastened without additional measures being required for this.
