Abstract

Improvements in the construction of pistons for internal combustion engines, such as large diesel engines, characterized in that they comprise a separate piston ring that is adapted to be attached to the upper end of a piston rod, which has a plurality of conduits drilled from one practically radial shape extending a short distance below the gas exposed face of the piston crown, from a coolant collection chamber located between the crown and the piston rod and in communication, through their radially outer ends, with ducts of coolant drilled axially extending behind the grooves of the piston rings or segments in the part of the skirt, said axial ducts opening at their lower ends, in an annular collecting chamber, said piston crown being of solid construction between its opposite face to gas, and its opposite face adapted to mate with the piston rod.
