Definitions
- the invention relates to a hydraulic support element for a valve control of an internal combustion engine, in which a piston is guided in a longitudinally displaceable manner in a housing and both parts enclose a pressure chamber between them, which is connected via a check valve arranged at the lower end of the piston to an antechamber provided in the piston is, wherein a sleeve-like inner element is arranged in the vestibule, which is supported in the axial direction on a shoulder of the piston.
- Such a hydraulic support element is previously known from US 45 84 976 in connection with a tappet or roller tappet.
- the sleeve-like inner element arranged in the anteroom has the task of preventing the oil from escaping from the antechamber when the support element is skewed.
- the sleeve-like inner element is supported in the axial direction on a shoulder of the piston, which is formed by a reduction in the diameter of the piston.
- the disadvantage here is that the piston can only be manufactured in a very costly manner by a cutting process due to the reduction in diameter, ie the piston has different inner diameters.
- the object of the invention is to develop a less cost-intensive mounting of the sleeve-like inner element in the anteroom while avoiding the disadvantages to date.
- this object is achieved according to the characterizing part of claim 1 in that the shoulder is formed by a curled step of the piston.
- the shoulder supporting the sleeve-like inner element is produced by a non-cutting process, i. H. the piston has different inside diameters over its entire length, but no different wall thicknesses. This in turn means that the elaborate machining of the piston due to its different inner diameters to form the shoulder is eliminated.
- the uncured sleeve-like inner element is pressed into the hardened piston.
- the uncured sleeve-like inner element should be caulked in the piston and both components should be subjected to an overall hardening.
- the uncured sleeve-like inner element is rolled into a groove in the hardened piston.
- the unhardened sleeve-like inner element should be held in the hardened piston by means of a locking ring.
- the sleeve-like inner element is glued or welded to the piston.
- the mounting or fastening of the sleeve-like inner element in the piston is not limited to the methods described in the subclaims. All types of connection familiar to the person skilled in the art are conceivable, it being possible for the sleeve-like inner element and / or the piston to be subjected to hardening.
- FIG. 1 shows a side view of a hydraulic support element, partially cut
- Fig. 2 u. 3 shows a fastening variant of the sleeve-like inner element.
- the hydraulic support element shown in FIG. 1 is part of a valve train (not shown), the support element being operatively connected to a gas exchange valve via a drag lever. It essentially consists of a hollow cylindrical housing 1 in which a piston 4 composed of an upper piston part 2 and a lower piston part 3 is slidably guided. This piston 4 is also hollow and has an antechamber 5 in its interior, which is connected via a bore 6 to a pressure chamber 7 enclosed between the lower piston part 3 and the housing 1. The connection between the antechamber 5 and the pressure chamber 7 is controlled by a check valve which consists of a ball 8, a spring 9 and a valve cap 10 which receives the two parts.
- the valve cap 10 is pressed against the piston lower part 3 by a helical spring 11 arranged in the pressure chamber 7 and serving to reset the piston 4.
- the upper piston part 2 ends with a spherical head 17 which is received in a socket of the mentioned rocker arm, not shown.
- Radial bores 18, 19 for an oil passage to the antechamber 5 are arranged in the upper piston part 2 and in the housing 1.
- the upper piston part 2 has a rolled-in step 12, so that a shoulder 13 is formed, on which a sleeve-like inner element 14 is supported in the axial direction.
- the upper piston part 2 has a constant wall thickness over its entire axial length, i. H. the different inner diameters or the shoulder 13 are not realized by different material thicknesses of the upper piston part 2 as described in the prior art.
- FIGS. 2 and 3 show two possible types of fastening of the sleeve-like inner element 14 in the upper piston part 2.
- the sleeve-like inner element 14 is rolled into a groove 15 in the upper piston part 2, while in the second case the inner element 14 is held by means of a snap ring 16 which snaps into the groove 15.
- valve cap 1 1 spring
