摘要： A carburetion arrangement for an internal combustion engine of a manually guided implement is provided. The arrangement includes a carburetor having an air channel, the cross-section of which is variable via a butterfly valve. An auxiliary carburetor having an auxiliary air channel is, in a flow conducting manner, connected in parallel to the air channel, whereby the auxiliary air channel opens into the air channel downstream of the butterfly valve. Disposed in the auxiliary air channel is a starting valve that includes a flow control device, wherein the starting valve alters the flow resistance of the flow control device as a function of the differential pressure that is present.

摘要： A pressure compensating valve is configured as a pressure control valve for a fuel tank. The valve body is operatively connected to a membrane via a two-arm valve lever so that, when there is an underpressure in a control chamber, which is bounded by the membrane, the membrane is displaced in the direction toward the lever. The lever is then pivoted and opens the valve for pressure compensating the fuel tank by allowing air to flow in.

摘要： A diaphragm carburetor for a combustion engine having a manual starter has a housing and a control chamber arranged in the housing and filled with fuel. A suction channel is arranged in the housing and has a venturi section. A throttle flap is rotatably supported in the suction channel downstream of the venturi section in the flow direction of combustion air sucked into the suction channel. A main valve path connects a control chamber to the venturi section. An idle valve path connects the control chamber to the suction channel and opens into the suction channel at a location downstream of the throttle flap in the flow direction. A choke flap is rotatably supported in the suction channel and positioned upstream of the venturi section. The choke flap has identical cold start and warm start positions and allows a flow volume of combustion air into the suction channel sustaining engine operation after the engine has been started.

摘要： A closure arrangement of a container has fill socket with an inner thread and a closure cap with a cylindrical base body having an outer thread matching the inner thread of the fill socket of the container. The cylindrical base body has an annular flange adjacent to the outer thread. An annular seal, connected to one side of the annular flange facing the outer thread, is provided for sealingly resting on the rim of the fill socket when the closure cap is threaded into the fill socket. The outer thread has a resilient tongue extending in the circumferential direction of the cylindrical body and has a radial projection cooperating with the abutment of the matching inner thread. The radial projection, when the closure cap is threaded into the fill socket, catches in a catch position behind the abutment before a fully closed position of the closure cap in the fill socket is reached.

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 relates to a handheld portable tool driven by a two-stroke engine equipped with a pneumatically actuated injection pump. Injection pumps for two-stroke engines are generally rigidly connected to the engine so that the injection line can be rigid and as short as possible. This, however, leads to operational disturbances in the injection pump. To eliminate these disturbances, the injection pump is mounted in a thermally insulated handle housing portion of the tool which is damped with respect to the vibrations of the engine and is connected to the latter via flexible connecting lines.

摘要： The invention is directed to a pump for use as a lubricating oil pump in internal combustion engines of handheld portable tools such as motor-driven chain saws or the like. The pump includes a body forming the stator and a body forming the rotor. These bodies lie coaxial with respect to each other and have respective surfaces which lie seal-tight against each other. A screw-shaped spiral slot is formed in one of these surfaces and has an input end connected to a suction connection and an output end connected with a pressure connection. According to a feature of the invention, at least the screw-shaped wall structure is made of an elastomer. This wall structure defines the spiral slot and lies against the smooth surface lying opposite thereto. An absolutely seal-tight contact engagement of the wall structure defining the spiral slot against the opposite-lying surface is assured by the elasticity of the elastomer. The service life of the pump is increased and its production and assembly simplified.

摘要： The invention relates to a fuel injection arrangement wherein the pump piston of the fuel pump is driven by the pressure in the crankcase of the engine. The fuel injection arrangement includes an opening for tapping the crankcase pressure for actuating a diaphragm in the fuel pump. This opening is controlled by a moving part of the engine such as a crank web or the piston. The moving part closes the opening at least for a portion of the time during which injection occurs thereby delaying the onset of injection to permit a complete combustion during the previous combustion cycle.

摘要： A two-stroke engine is disclosed which is controlled by a carburetor throttle valve and has a crankcase subjected to continuously alternating overpressure and underpressure. A pneumatic control member responsive to a signal dependent on the rotational speed of the engine is in pressure communication with the inner chamber of the crankcase via a valve. The output member of the pneumatic control member is connected with the throttle flap of the carburetor. The valve provided between the crankcase and the pneumatic control member is responsive to a signal for controlling the pressure in the pneumatic control member. This valve can be configured as a resonance control valve fixedly mounted to the housing of the engine. The resonance control valve has a mass oscillator which, at a correspondingly high engine speed and as a result of the vibration frequency associated therewith, acts upon a sealing diaphragm in the resonance control valve to open a pass-through opening communicating with the pneumatic control member.
