Abstract
In an internal combustion engine with a motor block (6) and a longitudinal extending anti-rotation guide (5), which includes receiving recesses situated at apportioned spatial distances, one from the other to receive valve tappets and is affixed in a receiving groove of the motor block (6). The guide (5) is constructed as an injection molded component with a one-piece, molded-on, elastically expanded or deformable clip, which engages in a complementary receiving contour on the motor block (6).
Claims6
An internal combustion engine with a motor block (6) and a longitudinally extending anti-rotation guide (5) including spaced apart receiving openings (2) adapted to receive valve tappets, the anti-rotation guide (5) is fastened in a receiving groove of said motor block (6), the guide (5) is constructed as an injection molded component with a one-piece, molded on. elastic outwardly expanding or deforming tubular clip which engages in a matching motor block receptacle;
- and
- the clip is formed from a plurality of tongues (7) disposed in a tubular arrangement, which are circumferentially separated from each other by axial parallel slots (8) and include on their free ends radially projecting rims (9).
