Definitions
- the invention relates to a valve clearance compensation device for internal combustion engines, consisting of a valve cup, a compensation element guided in the center of the valve cup and an elastomeric membrane extending from the valve cup to the compensation element, the fastening ends of which are thickened in a bead shape and interact with metal parts.
- valve lash adjuster consists of several individual parts that must be installed individually when installing the valve lash adjuster. Such systems cannot be used for tappets with a closed hydraulic system.
- the metal parts are angular clamping rings in cross section, which are positively embedded in the fastening ends of the membrane such that the respective axial leg of the clamping ring exerts a radial tension on the existing elastomer layer between the clamping ring and valve cup or compensating element and that at least the radial leg of each clamping ring has an elastomer-free surface to the side of an assembly tool and that the clamping rings in the fastening ends of the elastic membrane have a respective undercut that cooperate with the fastening ends of the elastic membrane in such a way that the clamping rings are secured against axial slipping out.
- the first clamping ring 13 is provided with an axially recessed base 16.
- the tubular area 15 of the clamping ring 13 has an undercut 17 at its ends and is positively connected to the bead 12 of the membrane 8.
- the second clamping ring 14 arranged in the bead 11 is angled and also has an undercut 17. Sealing lips 18, 19, which are bent radially in the direction of the compensating element 4, serve to support the sealing action at the fastening ends 11, 12 of the membrane 8.
- FIG. 3 shows a snap connection for axially fastening the membrane 8 in the valve cup 1.
- the membrane 8 is pressed over a circumferential radial projection 23, the projection 23 functioning as a ramp.
- the clamping ring 14 snaps against the inner circumference 9 of the valve cup 1, so that the membrane 8 is locked axially against slipping out.
