Patent ID: 6932046

Claim:
Use of a two cycle engine having at least one cylinder and a piston which can move in the cylinder, wherein oil is discharged exclusively in the form of an oil aerosol, in the region of a contact surface between the piston and the cylinder, onto a running surface of a piston skirt of the piston and onto a running surface of the cylinder; in or below the running surface of the cylinder, there is provided an oil outlet which is coupled to a conveying device and through which the oil aerosol is discharged onto the running surface of the piston skirt and onto the running surface of the cylinder, wherein the oil aerosol is discharged from the oil outlet alternately 1) onto the running surface of the piston skirt when the piston is located in the proximity of a lower dead center thereof, and 2) onto the running surface of the cylinder when the piston is in the proximity of an upper dead center thereof; wherein the quantity of the oil supplied is such that oil is minimized from exiting into a combustion chamber or into a crank chamber located below the piston; wherein the piston is coupled to a crank shaft via a connecting rod and a connecting rod bearing; wherein the connecting rod bearing has life-time lubrication or has a material pairing requiring no additional lubrication, wherein the tool has a movement-conversion device disposed in a housing for conversion of a rotary movement produced by the two cycle engine into a working movement; and wherein the two cycle engine is disposed on or in the housing; the housing is supplied with oil for the purpose of lubricating the movement-conversion device; and the two cycle engine is lubricated by the provision of the oil from the housing to the oil outlet.
