Improved piston for quick-running internal combustion engines
Реферат: 146,416. Mõdler, F. L. April 8, 1918, [Convention date]. Pistons, cooling.- Pistons for internal-combustion engines are made with an aluminium &c. bottom provided with cooling-ribs. Air is circulated through fixed pipes g, h, over which the piston reciprocates. The aluminium bottom d is screwed into the piston and secured by burring over the end of the screw thread. The air circulated is thus free from oil-vapour &c. contained in the crank-casing.
