In order to create ( ) with a motor ( ) which is fixed to a casing ( ) and which shows an intake port ( ) which is connected with a carbureter ( ) for decoupling oscillations over an elastic suction hose ( ), the carbureter ( ) itself taking its bearing on the casing ( ) by means of fixing means ( ), which avoids the disadvantages of the solution existing up to now and which makes possible especially a vibration-free bearing of the carbureter which is simple, easy servicing and which can be realized at low cost, it is proposed that the bearing of the carbureter ( ) on the casing ( ) is carried out substantially resiliently for damping or reducing the oscillations and the bearing of the resiliently hinged carbureter is carried out by means of an one-point suspension.

A two-cycle internal combustion engine (,) with additional engine oil lubrication system comprises a fuel tank (,) which can be filled with fuel through a filling opening which can be closed with a fuel tank cap (,), as well as an engine oil tank (,) which can be filled with engine oil through a filling opening which can be closed with an engine oil tank cap (,). A regular checking of the oil-level in the engine oil tank (,) is promoted by the fact that both tanks (,) with their tank caps (,) are so configured that, when filling the fuel tank (,), the operating person's attention is drawn to the engine oil tank (,).

Two-stroke internal combustion engine with an additional engine-oil lubricating system

The invention relates to a driving device for a motor driven vegetation cutter or the like with a two cycle engine showing an injection valve (,), a coupling placed in a coupling box (,), air intake and air blow-off devices, a fuel pump (,), a starter box (,) as well as eventual other additional sets. It is proposed so as to create a compact arrangement of the parts of said driving device with an optimal cooling and combustion to place the coupling box (,) and the starter box (,) on opposed sides of the two cycle engine and to direct the injection valve (,) with its jet direction onto the cylinder head or the ignition plug (,).

Driving device for a motor scythe

The invention refers to a driving apparatus for a lawn trimmer with a two-stroke motor having an injection valve, a coupling power output, air intake and exhaust gas discharge devices and a fuel pump as well as other possible additional components. For providing a compact construction and for guaranteeing the operativeness of the motor by fuel cooling and specific air guiding, the injection valve and a cooling air fan are placed on the same side of the motor cylinder block as the output coupling with the injection valve having a nozzle jet orientation directed to the ignition plug.
