Reciprocating piston for a reciprocating internal combustion engine and use of a reciprocating piston in a reciprocating internal combustion engine

摘要

The invention relates to a reciprocating piston for a reciprocating internal combustion engine having a base body (12) and a combustion chamber surface (16), wherein within the base body (12) at least one cooling duct network (32) is provided, wherein the cooling duct network (32) at least one - in the radial direction of the Viewed base body (12) - arranged on the inside inflow region (34) and a plurality of - starting from the inflow region (34) - in the radial direction in each case outwardly extending mini-cooling channels (42), wherein the mini-cooling channels (42) a maximum cross-sectional width of 3 mm. In this case, the inflow region (34) comprises an annular channel (40) or a central reservoir and the mini-cooling channels (42) extend outwardly from this annular channel (40) or the central reservoir in the radial direction, wherein the annular channel (40) or the central reservoir is designed in the manner of a coolant collecting space and has a cross-sectional area corresponding to at least 1.5 times the largest cross-sectional area of the largest mini-cooling channel (42).
