摘要： The present invention relates to a closure arrangement on a tank (1 ) of a hand-held working tool driven by a power unit, said tank containing an operating fluid of the hand-held working tool. The closure arrangement comprises a filler neck (10), defining an opening (2) in the tank (1 ) for filling of operating fluid, and a closure cap (20), for closing of the opening (2). The closure cap (20) is arranged to be brought from an opened position, wherein the closure cap (20) is separated from the filler neck (10), towards a closed position, wherein the closure cap (20) is tightened to the filler neck (10). The filler neck (10) has a first closure element (12) and the closure cap (20) has a second closure element (22), which first closure element (12) and second closure element (22) are arranged to interact with each other, in such a way that the user receives an indication when the closure cap (20) reaches the closed position.

摘要： A crankcase scavenged two-stroke internal combustion engine (1) having an additional air supply (2) arranged to its transfer ducts (3), connecting a crankcase volume (4) and a transfer port (5). There is at least one recess (6, 24) in a piston (7) arranged below a piston ring (10, 11), and further there is a flow channel (12; 13; 14) arranged in the piston or in a cylinder wall (29) of the engine cylinder (9), and the recess is arranged to register with the transfer port and the flow channel for certain piston positions, i.e. to create a communication between the transfer port/s and the crankcase volume. This will take away the pressure fluctuations in the transfer duct. At the same time or preferably thereafter the transfer port will be connected to an additional air supply.
摘要翻译：曲轴箱清扫的二冲程内燃机（1）具有设置在其输送管道（3）上的附加空气供应（2），连接曲轴箱体积（4）和输送口（5）。在活塞（7）下方设置有至少一个设置在活塞环（10,11）下方的凹部（6,24），并且还有一个设置在活塞或气缸中的流动通道（12; 13; 14）发动机气缸（9）的壁（29），并且凹部被布置成与传送端口和流动通道对准某些活塞位置，即在传送端口和曲轴箱体积之间形成通信。这将消除传送管道中的压力波动。同时或优选地，传输端口将连接到附加的空气源。

摘要： A hand- he Id work apparatus includes an engine housing (200). An internal combustion engine (202) is arranged in the engine housing (200) and includes a cylinder (204) and a crankshaft. A fan wheel (214) is driven directly or indirectly by the crank shaft, such that the fan wheel (214) rotates about an axis A. A fan housing (216) surrounds and cooperates with the fan wheel (214). A combustion air inlet (224) is located radially outside of the fan wheel (214) for leading air to the internal combustion engine (202). Further, the combustion air inlet (224) includes a combustion air inlet port (226) and a combustion air duct (228). The combustion air inlet port (226) is provided with a first edge (230), which first edge (230) is located radially adjacent to the periphery (220) of the fan wheel (214). An angle X between a first line L1 extending radially from the axis A in a direction parallel to a main direction of the cylinder (204) and a radius L2 extending radially from the axis A in a direction such that it intersects with the first edge (230), is less than 70° and preferably less than 66°, and even more preferably less than 62°.
