摘要： The invention relates to a two cycle engine comprising a lean lubrication system, whereby the lubrication oil is only applied in the area of a contact surface between a piston and a cylinder. An oil outlet is provided in or below a running surface pertaining to the cylinder for this purpose. An oil aerosol can be applied alternately, according to the position of the piston, onto the running surface of a shaft pertaining to the piston and onto the running surface of the cylinder via said oil outlet.

摘要： The invention relates to an oil supply for an internal combustion engine, comprising an oil supply device for the supply of oil to a piston, reciprocating in a cylinder. The oil supply device is embodied such that at least at a point at which the piston is in the region of bottom dead centre, oil is introduced directly into a region below the piston, by means of the oil supply device, in particular, beneath the piston crown and within the piston skirt. The oil supply device thus comprises at least one tube element, extending into a region beneath the piston crown. The tube element terminates as close as possible to a gudgeon pin, when the piston is at bottom dead center. A targeted lubrication of the mechanically and thermally highly loaded gudgeon pin can thus be guaranteed. It is also possible by means of the oil supply to supply transfer ports of a two-stroke engine with oil, counteracting a tendency to coke up.

摘要： A tool consists of a combination engine in the form of a two-cycle engine, and a motion conversion device which is connected to said combustion engine and which is located in a housing. The housing is filled with oil for lubricating the motion conversion device. A conveying device with which the oil is conveyed from the housing to the combustion engine is provided, said combustion engine being lubricated exclusively with oil from the housing and having no separate oil supply.

摘要： A percussion tool has a cooling air channel for guiding a cooling air flow from a cooling air fan to an outside wall of a cylinder of an internal combustion engine. The cooling air channel is tapered to the extent that partial cooling air flows guided between the respective cooling fins are branched off the main cooling air flow. In such a way, the flow rate of the cooling air flow in the cooling air channel remains substantially constant, resulting in optimized engine cooling. The cooling air channel may be divided into two cooling air channels downstream of the cylinder. One of the cooling air channels guides cooling air to an exhaust gas system of the internal combustion engine, while the other cooling air channel guides cooling air to an outside wall of the guide housing of a hammer mechanism.

摘要： An implement comprises an internal combustion engine having a throttle valve. At least one handle, the inside of which is provided with a gas lever likewise in a pivotal manner, is attached to a housing surrounding the internal combustion engine. The minimum distance between the gas lever and the handle is defined by a stop. When the operator lifts the implement by the handle, the position of the gas lever also changes. Even when the gas lever is fully depressed, only a part-load position is achieved at the throttle valve. In this way, effective rotational speed limitation is achieved.

摘要： A throttle actuating device for an internal combustion engine of a soil compacting device, the internal combustion engine having a diaphragm carburetor and a connection between the fuel tank and the diaphragm carburetor, includes a control mechanism for switching the diaphragm carburetor into different operating positions including a full load position, an idle position, an intermediate position, and a turn-off position for the internal combustion engine. The intermediate position is located between the idle position and the turn-off position in the travel path of the control mechanism. The control mechanism, when being moved from the idle position toward the turn-off position, shuts off the connection 32 for interrupting fuel flow from the fuel tank to the diaphragm carburetor when passing through the intermediate position. The control mechanism, when being moved from the turn-off position toward the idle position, opens the connection to allow fuel flow from the fuel tank to the diaphragm carburetor when passing through the intermediate position.
