Abstract

PURPOSE: To rapidly return excessive lubricating oil to a crank chamber, to reduce an amount of oil consumed, and to prevent reduction of a blow-by gas circulating amount, by a method wherein an oil return passage, adapted to return lubricating oil from a locker arm chamber to a crank chamber, is installed, and a check valve is located in the passage.
CONSTITUTION: Lubricating oil is stored in the lower part of a crank case 1, and a splasher 6 is integrally mounted to a cap 4a adapted to connect the large end part of a connecting rod 3, connected to a piston 2, to a piston 4. Through rotation of the splasher 6 along with reciprocating movement of the piston 2, lubricating oil is splashed, and circulates in pipes 11 and 12 to lubricate each part. In this constitution, an oil return passage 25 is formed in the lower end of a containing part 24 into which a push rod 21 is inserted, and a check valve 30, allowing only a flow destined for the crank chamber, is situated in the passage 25. Lubricating oil gathering at the bottom of the containing part 24 is caused to flow through the check valve 30 down to the crank chamber.
