摘要： The air cleaner (32) comprises a base member (41) including a base wall (41A) extending substantially horizontally, and a cover member (42) attached to an upper side of the base wall to jointly define a filter chamber (70) for receiving a filter element (43) therein. The air cleaner further includes a passage member (44) communicating with the filter chamber and incorporated with a plurality of air ejection pipes (44C) each surrounded by an annular air inlet passage (44E) fitted with guide vanes (44D) for rotating the air flow, and a case member (45) defining separation chambers (45C) for separating dust from the rotating air flow. The passage member (44) is interposed between the cover member (42) and the case member (45).

摘要： Herein a control system (10) for controlling an internal combustion engine of a hand-held power tool (2) is disclosed. The control system (10) comprises an electronic control logic (24), a first and a second sensor (26, 28). A first conductive path (36) comprises the first sensor (26). A second conductive path (38) comprises the second sensor (28). The first and second conductive paths are connected to an input (40) of the electronic control logic (24). The first and second conductive paths are connected to a fixed voltage potential. The first conductive path (36) has a first electrical property and the second conductive path (38) has a second electrical property. The first electrical property and the second electrical property together are different from at least one of the first electrical property and the second electrical property, such that the electronic control logic (24) is able to detect different states.

摘要： To improve responsiveness of fuel supply control, a rotary carburetor 100 has a nozzle 8 including a fuel discharge port 8a and a needle 10 disposed coaxially with the nozzle 8 and disposed with a portion inserted into the nozzle 8. The needle 10 can be displaced relative to the nozzle 8 to change an effective area of the fuel discharge port 8a. The rotary carburetor 100 has an electric motor 14 for displacing the needle 10 along an axis, and a drive mechanism component 12 interposed between the electric motor 14 and the needle 10 and converting a rotational movement of the electric motor into a linear movement.

摘要： A two-cycle engine (10) includes a crankshaft (13) that has shafts (17, 18) on both sides and a crankcase (12) that pivotally supports the shafts (17, 18) of the crankshaft (13) through bearings (21, 26). A collar (29) is circumferentially provided on an outer ring of one of the bearings (26) that supports one of the shafts (18) on a side at which a low load is applied. The crankcase (12) is provided with an inserting portion (24) into which the one of the bearings (26) is inserted. The inserting portion (24) penetrates the crankcase (12) while keeping a constant diameter. An engaging portion (27) with which the collar (29) is engaged from an inner side is provided in an inner portion of the inserting portion (24).

摘要： Eine Anwerfvorrichtung (8, 108) für einen Verbrennungsmotor (9) besitzt ein Anwerfseil (34), an dem ein Anwerfgriff (35) festgelegt ist. Die Anwerfvorrichtung (8, 108) besitzt eine Seilführung (38) für das Anwerfseil (34), die das Anwerfseil (34) von einer Seilrolle (23) der Anwerfvorrichtung (8, 108) zu einer Seilaustrittsöffnung (36, 136) führt. Die Seilführung (38) umfasst mindestens eine Umlenkrolle (40, 41, 42). Die Seilaustrittsöffnung (36, 136) ist am Umfang der Umlenkrolle (40) der Seilführung (38) angeordnet und erstreckt sich über einen Umfangswinkel der Umlenkrolle (40) von mindestens 60°. Dadurch kann der Anwerfgriff (35) in unterschiedlichen Richtungen aus der Seilaustrittsöffnung (36, 136) austreten und ermöglicht so ein ergonomisches Anwerfen. Die Anwerfvorrichtung (8, 108) ist vorteilhaft für den Verbrennungsmotor (9) eines rückengetragenen Arbeitsgeräts vorgesehen.
