Abstract (en)
[origin: WO03085251A1] An oil inlet (2) for a piston (1) provided with a cooling duct (4) and installed in an internal combustion engine is designed in order to enable an improved concentration of a cooling oil stream when entering the oil inlet and an improved distribution when exiting into the cooling duct. To this end, the inner wall surface (3) of the oil inlet (2) is shaped according to a function of a one-sheeted rotating hyperboloid or of a surface-delimited torus, whereby the shape is determined according to a stream position of the cooling oil stream (7), which is produced by an oil spraying nozzle (6), relative to the cross sectional opening area (B, D) of the oil inlet.
