摘要： An internal combustion engine is provided, and has a throttle element mounted in the intake channel of the engine so as to be pivotable, via a throttle shaft, between an idling position and a full-load position. An abutment is fixedly connected with the throttle shaft. In the idling position, the abutment rests against a stop element that is fixed in position on the intake channel. The stop element is adjustable and establishes the idling position of the throttle element. The abutment forms, with the stop element, a switch that is actuated in the idling position of the throttle element.

摘要： The invention relates to a fuel-metering arrangement for the mixture-forming unit (2) of an internal combustion engine (10) in a portable handheld work apparatus. The mixture-forming unit comprises a fuel store (30), a switchable valve (40) and a fuel channel (20) which opens into an intake region of the engine (10). The valve (40) has an inflow port (41) which is connected to the fuel store (30) and an outflow port (42) which is connected to the fuel channel (20). A fuel column is mechanically moved by the switching of the valve. In order to compensate for this fuel column, the outflow port (42) is connected via a bypass channel (45) to the inflow port (41) and a flow valve (46) is mounted in the bypass channel (45). The flow valve (46) opens in flow direction (49) from the outflow port (42) to the inflow port (41) and blocks in the direction opposite thereto.

摘要： An internal combustion engine having an intake channel that is divided by a partition into an air duct and a mixture duct. The partition has a connecting opening that at least at full throttle of the internal combustion engine is substantially closed. A main fuel opening opens out into the mixture duct. At least one further fuel opening is provided that opens out into the mixture duct at a first distance relative to the wall of the intake channel and at a second distance relative to the partition.

摘要： The invention relates to a carburetor arrangement of a portable handheld work apparatus and includes a carburetor (1), an accelerator pump (2) and a venting pump (3). The venting pump (3) acts on the accelerator pump (2) via a venting line (4). A check valve (5) is mounted in the venting line (4) in such a manner that its outlet end (6) is directed in the direction of the venting pump (3). A pretensioning device (7) is provided which holds a valve body (8) of the check valve (5) closed below a selected difference pressure between the outflow end (6) and an opposite-lying inflow end (9). A support device (10) which acts on the valve body (8) and is actuable, at one end, by pressure at the outflow end (6) without considering pressure at the other end (9) or by pressure on the inflow end (9) without considering the pressure on the other end (6).

摘要： A diaphragm carburetor for an internal combustion engine is provided, and has a housing with an impulse pressure driven fuel pump. Provided in the housing is a chamber that is divided by a diaphragm into a pump chamber and a drive chamber that is acted upon by impulse pressure fluctuations during operation of the internal combustion engine. In order with the least available impulse pressure differences of the engine to effectively deflect the diaphragm in the chamber, the freely movable diaphragm surface of the diaphragm is maximized and the conveying stroke of the diaphragm is enhanced by a spring. The movable diaphragm surface assumes a major portion of the surface of the plane of separation in which the diaphragm is disposed. For this purpose, a fuel intake valve and a fuel outlet valve are spaced from the diaphragm, and in particular are removed from the plane of separation in which the diaphragm comes to rest.
