Definitions
- the invention relates to a valve lever according to the preamble of claim 1.
- a valve lever is known from DE 195 43 657.
- strip-shaped tabs are provided for lateral guidance of the lever on the valve, which connect in the longitudinal direction to the actual valve lever o and which are folded down by 180 about an axis running transversely to the lever on the underside of the lever.
- this solution requires increased material expenditure, since the sheet metal from which the lever is formed must be extended by the strip-shaped tabs.
- the connection cross section of the strip-shaped tabs with the lever is so small that the tabs can be fixed on the lever e.g. B. is required by spot welding.
- the invention is therefore concerned with the problem of achieving a side guide with such a lever, which uses little material and has high strength.
- the sections that guide the valve lever on the valve base are integral with the valve lever. Since the sections that guide the valve lever on the valve foot are cut out of the sheet metal and folded down in the area in which the valve lever contacts the valve, this results in a guide that is stiff compared to the prior art with a large material cross section between Valve lever and section, which therefore no longer has to be fixed to the lever by special methods such as spot welding.
- the wall of the valve lever with which it contacts the valve base is defined as the lower wall, meaning below means in the direction of the valve base.
- the position of the lower wall of the valve lever is defined as approximately horizontal.
- the lever has an approximately U-shaped cross section in the longitudinal direction before and after the area in which it contacts the valve.
- the sections forming the guide can either be folded out according to claim 4 from the lower wall of the approximately U-shaped cross section or according to claim 5 from the side walls of the U-shaped cross section.
- Fig. 1 shows a valve lever, in which the sections causing the guide are folded out of the side walls, in longitudinal section
- Fig. 2 shows the valve lever of FIG. 1 in cross section
- Fig. 3 shows a valve lever, in which the sections causing the guide are folded out of the lower wall, in cross section.
- a valve lever 1 has a rear part 2, with which it is supported against a play compensation element (not shown), a middle part 3, on which it is actuated via a camshaft and a roller bearing, and a front part 4. With the wall 5 of the front part 4 pointing downwards, the valve 6 to be actuated is contacted.
- the valve lever has an approximately U-shaped cross section, which is composed of the lower wall 5 and two side walls 10 and 11.
- sections 7 and 8 are cut out of the side walls 10 and 11 on 3 of 4 sides, which are bent or rotated downwards by 180 with the fourth, not cut-out side as an axis of rotation, the distance between the two sections to each other is slightly larger than the width of the valve foot and the sections 7 and 8 together lead the valve lever 1 on the valve 6.
- the length of the area which has been cut out and folded down can be seen in FIG. 1 on the basis of the slightly curved strip above the wall 5.
- the cross section of the valve lever in the area of the folded-over sections is composed of two narrow upper webs belonging to the side walls 10 and 11, the underside of which leads to those created by folding out the sections 7 and 8 in the walls 10 and 11 Has openings and an inverted U-shaped wide lower web, which is composed of the lower wall 5 and the folded sections 7 and 8th
- the inwardly facing surfaces of the sections 7 and 8 and the underside of the wall 5, that is to say the surfaces contacting the valve, can be ground.
- the sections 12 and 13 effecting the lateral guidance of the valve lever are cut out of the lower, horizontally extending wall of the lever and folded down by 90.
- the cross section of the valve lever in the region of the folded sections is composed of the two side walls 10 and 11, and of the horizontally extending wall 5 with the sections 12 and 13 folded down from the horizontal wall, so that between the horizontally extending sections Wall 5 and the side walls 10, 11 creates a narrow opening extending in the direction of the valve lever.
- the necessary cuts can be made before folding over or with the same tool that also folds down or bends the sections down.
