摘要： The invention relates to a crankcase scavenged internal combustion engine (1) of two-stroke type, comprising a cylinder (2) with an inlet tube (10) for air/fuel mixture and a number of transfer ducts (20), a carburettor (12) connected to the inlet tube (10), and an air inlet (24) provided with a restriction valve (25) whereby a piston ported air passage (23, 22, 26, 21) is arranged between the air inlet (24) and the upper part of the transfer ducts (20). The engine's air inlet (24) extends at least partly below and outside the carburettor (12), resulting in a more compact engine design and improved use of the space around the cylinder. Moreover, the cooling air gets better access to the cylinder.

摘要： The invention refers to a cylinder (1) for a two-stroke, crankcase scavenged combustion engine, comprising an inlet pipe (10) for air/fuel mixture, at least one transfer port (17), and at least one outer connecting port (18) intended to be connected to a connecting duct (not shown), whereby the outer connecting port (18) is arranged so that it can be connected to the mentioned transfer port (17) via a piston ported air passage. The outer connecting port (18) is located below the inlet pipe (10) and at least one wall passage (14) extends from the mentioned outer connecting port (18), obliquely upwards through the cylinder wall, to at least one connecting port (16). This design enables the cooling air to flow freely around the cylinder above the inlet pipe (10), which improves the cooling of the cylinder.

摘要： The invention refers to carburettors for crankcase scavenged two-stroke engines utilizing additional air that is led via scavenging ducts into the combustion chamber of the engine. More particularly it refers to a valve arrangement at the inlet of the additional air duct (3; 23). The advantage of the novel valve is that it is turned around a shaft (6; 26) located outside the additional air duct, whereby it will not disturb the flow of air into this. The valve is controlled synchronically by the engine throttling by means of a link rod arrangement, or an eccentric sheave push rod construction, in both cases with mechanical connection to the turning shaft of the throttle valve.

摘要： A crankcase scavenged two-stroke engine (1) comprises a cylinder (15) including scavenging ports (31, 31') and at least one exhaust port, a piston (13), a connecting rod (17), a crankshaft (18) and a generally sealed crankcase (16). The crankcase inducts a fuel/air mixture and is connected to the scavenging ports (31, 31') by means of transfer ducts (3, 3') which, as the piston (13) is travelling from a lower position towards a higher position, are inducting pure air let in from connecting ports (8, 8') near the scavenging ports (31, 31') in the cylinder (15). The transfer duct (3, 3') volume is less than 20 % of a volume swept by the piston (13) during an entire revolution of the crankshaft (18). Recesses (10, 10') are formed in an outer periphery of the piston (13), said recesses (10, 10') co-operating with the connecting ports (8, 8') in the cylinder wall for controlling the filling of the transfer ducts (3, 3') with air. An inlet tube (22) in the cylinder wall supplies the air/fuel mixture, said inlet tube (22) being connected to the crankcase (16) and covered by the piston (13) as the piston (13) is in the lower position, and open to the crankcase (16) as the piston (13) is in the higher position.

摘要： This invention relates to a throttle control device for a hand held tool, such as a chain saw. The tool is provided with a forwardly extending wire (17) for transmitting a motion from a throttle control lever (12) turnably arranged about a first axis (14) to a throttle valve. One end of the wire is secured to a wire arm (15) that is turnably arranged about a second axis (16). The wire arm is provided with one or several teeth (19, 20) cooperating with corresponding means on the throttle control lever (12) and the second axis (16) is arranged behind the first axis (15).

摘要： Flange assembly (56) for supporting a structure that provides scavenging air supply to an internal combustion engine (40) at the carburetor (42) to the engine. The assembly includes a thin-body flange (58) that is configured to be abuttingly installed upon an end surface (48) of the carburetor. The carburetor has its combustion air intake (50) or port exposed at an outer surface for intaking air for the combustion process. The thin construction of the flange enables advantageous positioning of the adaptive flange. The relative dimensioning of the thin-body flange (58) also contributes to its low-impact as a modification to air inlet arrangement. A combustion air aperture (60) is provided that extends through the thin-body flange. The combustion air aperture (60) is located in the flange for alignment with the combustion air intake. By this alignment, fluid communication is established across the flange and into the carburetor when the flange is abuttingly installed upon the carburetor. A scavenging air aperture (64) also extends through the thin-body flange and is spaced apart from the combustion air aperture. A valve assembly (76) is operatively coupled to the thin-body flange and has a valve element (78) positioned at the scavenging air aperture (64) for opening and closing the scavenging air aperture.
