Field of the Invention The present invention relates to a mechanical valve play compensating member used particularly for compensating valve play in an internal combustion engine. A valve play compensating member of this kind is supported at one end on a part fixed to the frame and at the other normally spherical end (spherical head) on the crown portion of the swiveling lever. The valve play is adjusted by the change in the distance between the end supported on the part fixed to the frame and the spherical head.

である。2. Description of the Prior Art In a mechanical valve play compensating element, which is known, for example, from DE-A 25 40 220, the corresponding bearing of the rocking lever is spring-elastically supported by means of a spring. . The corresponding bearing consists of a spherical head, which engages a spherical crown-shaped bearing cup provided at the end of the rocking lever. The spherical head has a stopper collar at its lower end, on which the bearing spring acts. The central hole of the spherical head serves to guide the pin of the bearing bolt,
A bearing bolt is adjustably retained in the cylinder head with a threaded bush by means of a self-locking screw. By adjusting the bearing bolt with respect to the valve head or the screw bush, the valve play is adjusted, for which the upper end of the bearing bolt pin is formed as a hexagonal edge. The bearing bolt pins are only needed for adjusting the valve play, they are not necessary for normal operation of the internal combustion engine, which undesirably increases the mass.

For adjusting the valve play, a commercially available hexagonal wrench is inserted into the adjusting part through the opening of the rocking lever, through the support part and the locking part. By turning the hexagonal wrench, the adjusting part pivots with respect to the support part and thus the support part is moved inward or outward with respect to the casing or frame part in correspondence with the threaded lead. After precisely adjusting the valve play, the hex wrench is disengaged (pulled out) from the adjustment part, but is still engaged with the locking part. The locking part is then tightened towards the adjustment part, so that the adjustment part is pivotally locked with respect to the support part. The tool, the hex spanner, is then removed. That is, unwanted mass is removed from the moving parts.
