Bucket-shaped housing for a valve tappet provided with a hydraulic self-adjusting clearance-adjusting element

摘要

In a bucket-shaped housing (1) for a valve tappet, provided with a hydraulic self-adjusting clearance-adjusting element (5), for internal combustion engines with overhead camshaft with a funnel-shaped guide part (3) for the clearance-adjusting element (5) fixed on the bore wall (2) of the housing (1) by means of welding, especially laser welding, a circumferential groove (9) with a bead-like rear wall (10) being inserted by a non-cutting process in the outer circumferential surface (8) of the housing (1), on the side face of which groove facing the open end of the housing (1) the guide part (3) is supported, the metal particles melted off during the welding are prevented from getting into the inside of the housing (1) in that the side face of the bead-like rear wall (10) has an annular plane surface (11), on which the guide part (3) bears by means of a corresponding plane surface (12). <IMAGE>
