Abstract RU 2528232 C2

FIELD: engines and pumps.

SUBSTANCE: invention relates to hand-held devices driven by ICE. Proposed device comprises housing of engine (200) and ICE (202) with cylinder (204) and crankshaft. It incorporates fan wheel (214) driven by crankshaft to run about axle A. Fan casing (216) surrounds fan wheel (214) to interact therewith. Inlet (224) for air to be combusted is arranged radially outside fan wheel (214) to direct air to ICE (202) and has inlet (226) and channel (228). Inlet (226) has first edge (230) radially abutting on has wheel (214) outer periphery (220). Angle X between first line L1 extending radially from axle A parallel with the main direction of cylinder (204) and radius L2 extending radially from axle A so that to cross said first edge (230), is smaller than 70 degrees, preferably, smaller than 66 degrees and, more preferably, than 62 degrees. Invention covers the versions of hand-held device.

EFFECT: decreased weight.

20 cl, 6 dwg
