FIELD: engines and pumps.SUBSTANCE: piston 1 comprises cooling chamber 4 confined by bottom 5 and web 6 isolating said chamber from engine crankcase, feed and discharge channels and extra discharge channels 8, 9, 10. End of discharge channel 9 on cooling chamber end is located in zone adjoining said web 6 so that portion of coolantis shut off by said end in cooling chamber 4 at fitting the piston on horizontal plane with its bottom upside. Extra discharge channel 10 on cooling chamber side located in zone adjoining said piston bottom 5 shuts off portion of coolantpiston being fitted on horizontal plane with its bottom downward. Valves 12, 13 are arranged in discharge channel 9 and extra discharge channel 10. Said makes control coolant masses ratio in working cycle equal towhereis coolant weight in first cylinder piston,is coolant weight in second cylinder piston, ? is crankshaft angle of turn relative to first cylinder; ? is engine mechanism constant; mis piston weight.EFFECT: lower dynamic loads at engine crank gear.4 dwg |
