Definitions
- the piston 1 in its piston crown-side area has a collecting space 12 for Kuhlol, which is delimited by the piston crown 5 and radially on the outside partly by the upper part foot 9 and partly by the hub support 11 by means arranged in the radial direction in the support foot 11 and via the Scope of distributed overflow channels 13, the collecting chamber 12 is connected to the cooling channel 6.
- the collecting chamber 12 is connected to the piston-side piston interior 15 via further outlet channels 14 lying in the radial direction
- FIG. 2 an enlarged illustration of the detail A from FIG. 1, shows in cross section the region of the upper part 9 on the shaft side, which is in contact with the bearing surface 17 on the piston base side 17 of the supporting foot 11 via its end surface 16 on the piston side.
- These overflow channels 13 are, as shown by way of example in FIG. 2, via bores 18 arranged in the axial direction with flat cross-sectionally Shaped lubrication grooves 19 connected, which are molded into the support surface 17 and have a depth of 10 microns to 500 microns
- the lubrication grooves 19 are located on the support surface 17 of the support foot 11, but they can also be molded into the end surface 16 of the upper foot 9 or in both surfaces 16 and 17
