Definitions
- Cooling duct cover and piston provided with a cooling channel cover
- a generic cooling channel cover is known from EP 1 238 191 B1.
- This known cooling channel cover has an inherently elastic feed element, which is received in an opening provided in the cooling channel cover and fastened thereto by means of a latching connection or by clipping.
- the known feeding element is elastically deformed inwardly to allow it to pass through the opening in the cooling channel cover.
- This requires that the known feeding element is provided only with very small solid locking lugs and contact surfaces, which have very little contact with the cooling channel cover.
- a safe operation of a provided with such a cooling channel cover piston is not reliably ensured due to the forces occurring in the engine operation on the locking lugs and contact surfaces and the wear occurring in the region of the locking lugs and bearing surfaces.
- Figure 3 shows another embodiment of a cooling channel cover for a
- FIG. 5 a representation of the contact surfaces on the feed element according to FIG. 4;
- FIG. 3 shows another embodiment of a suitable for the present invention cooling duct cover 130.
- the cooling duct cover 130 consists of two semicircular part covers 131, 132, which are made in the embodiment of an elastic spring plate and two end faces 133, 134; 135, 136. Two opposing end portions 143, 144; 145, 146 of the partial covers 131, 132 form an impact gap 137, 138.
- In each partial cover 131, 132 is respectively an opening 141, 142 for receiving a feed element 50 according to the invention introduced.
- Each aperture 141, 142 is located adjacent to a bump gap 138, 137.
