摘要： The invention is directed to a fuel pump for an internal combustion engine such as a two-stroke engine in a portable handheld work apparatus such as a motor-driven chain saw or the like. A pump chamber is connected via a suction valve to a fuel feed and via a pressure valve to a pressure line. A pump membrane delimits the pump chamber and is driven by the fluctuating crankcase pressure of the engine which is present in the work chamber. Pump operation free of disturbances over a wide rpm range is attained with the suction valve to the pump chamber being configured essentially as a valve having the shape of a part circle, The pressure valve is disposed approximately at the center of the suction valve and delimits the pump chamber in the stroke direction of the pump membrane.

摘要： The invention is directed to a fuel-injection arrangement for a two-stroke engine in a portable handheld work apparatus such as a motor-driven chain saw or the like. Fuel is drawn by suction from a fuel tank by a fuel-feed pump and is made available at the suction connection of an injection pump. The injection pump has a pressure connection which is connected to an injection line through which the engine is supplied with fuel. A rapid start of a two-stroke engine provided with this fuel-injection arrangement is achieved by providing a bypass line which conducts fuel and bypasses the injection pump. A switchable flow valve is mounted in the bypass line. The bypass line opens directly into the intake channel conducting combustion air to the engine so that even without the pump action of the injection pump, adequate fuel is made available to the engine for starting the same.

摘要： The invention is directed to a fuel-injection arrangement for a two-stroke engine in a motor-driven chain saw. An injection pump is mounted in a base housing with the injection pump including a pump piston axially displaceable in a pump cylinder. The pump piston delimits a pump chamber. The pump chamber is connected via a suction valve to a fuel tank. The fuel drawn by suction is pumped by the pump piston via a pressure valve, an injection line and an injection valve to the engine. For driving the pump piston, the latter is connected at one end to a membrane via a membrane plate. The membrane delimits a work chamber charged with fluctuating crankcase pressure. A simple assembly is provided by arranging the pump chamber, the suction valve and the pressure valve in a common valve housing which, in turn, is seated in the base housing of the injection pump in a seal-tight manner. The injection line is connected directly to the valve housing. This permits a preassembly of the valve housing with the valves provided therein which facilitates the manufacture of the fuel-injection arrangement.

摘要： A suction head is provided for the end of a fuel hose in a fuel tank of a portable implement. The suction head comprises a cup-shaped housing of polymeric material that is closed off by a cap. Provided on the cap is a connector for the end of the fuel hose. The outer surface of the housing is provided with window-like cutouts that are covered by a filter mesh. In order also with narrow, fragmented tank housings to ensure an immersion of the suction head into the fuel in every operating position, a rod-shaped weight member is disposed in the center of the housing. This weight member extends from the base of the housing to the cap, with a first end of the weight member being held on the base and a second end being held on the cap.

摘要： The invention refers to a downdraft carburetor for internal combustion engines, the choke tube cross-section being controlled by a choke tube valve whose movement is controlled as a function of the control pressure in the choke tube by means of a diaphragm and lever with spring support. The choke tube and the choke tube valve have the shape of a venturi nozzle. The control of the choke tube valve is so arranged that the closing moment increases with closing of the choke tube valve. A damping system is provided which consists of a diaphragm box placed in the float chamber of the carburetor and which is connected by means of levers with the levers controlling the choke tube valve.

摘要： A starter device for an internal combustion engine includes a starter drum which can be coupled to the crankshaft (3) of the engine via at least one catch (13, 23). The catch (23) has at least one pivotally journalled pawl (25) which coacts with an entrainer (19) in a first position (44) and connects the starter drum to the crankshaft (3). In a second position (45) of the pawl (25), the crankshaft (3) and the starter drum are decoupled from each other. A wall (28) is arranged radially outside of the rotational axis (29) of the pawl (25). A gap (34) is formed between the pawl (25) and the wall (28). In order to prevent that the movability of the pawl (25) is negatively affected by dirt collected between the pawl (25) and the wall (28), the width of the gap (34) changes with the pivoting of the pawl (25).

摘要： The invention is directed to a carburetor arrangement in a housing (1) and especially in the housing of a work apparatus such as a motor-driven chain saw or like portable handheld work apparatus. An engine (2) is mounted in the housing (1) and has an inlet channel (3) which is connected via a connecting pipe (4) to the intake channel section (5) of a membrane carburetor (6). An intake air filter (10) is mounted on the carburetor (6) on the end face (17) facing away from the connecting pipe (4). Combustion air is supplied through the intake air filter (10). To avoid a damaging warming of the carburetor, a heat-draining component (20) is mounted on the end face (17) of the carburetor which faces away from the connecting pipe (4). The component (20) projects beyond the contour of the carburetor (6).

摘要： The invention relates to a portable handheld work apparatus having an internal combustion engine and an injection pump. The work apparatus includes an injection-pump block which is mounted on the housing of the work apparatus. The injection-pump block includes a feed pump for pumping fuel from a fuel tank mounted in the housing of the work apparatus and the injection pump for injecting fuel into the engine. An interface is provided between the block and the housing through which connecting lines are passed. Each line includes a connecting receptacle and a plug-in element at the interface. The plug-in elements jointly engage corresponding ones of the connecting receptacles when the injection-pump block is seated in the housing of the work apparatus. In this way, all connections of the connecting lines are made simultaneously when fixing the injection-pump block in position. A simplified installation of the injection-pump block in the housing of the work apparatus is achieved with the invention.
