Abstract

A start device for a small-sized engine, which can start the engine in an appropriate start time and which is ultimately reduced in size and weight by rational design. The start device has a small-sized electric motor (131) and secondary batteries. The batteries are used as the power source necessary for the drive of the small-sized engine, have a relatively large capacity, and are extremely reduced in size. A reduction gear mechanism (132) with a reduction ratio of 1 / 30 - 1 / 90 is placed between the electric motor (131) and a cushioning and force storage section (110). The start device can start the engine in an extremely short time of 0.4 - 1.3 seconds which does not cause any inconvenience to the operator.

Description

technical field [0001] The present invention relates to a battery pack incorporating a compact and high output battery capable of driving an extremely small electric motor used to start a variety of manual work machines such as portable brush trimmers, chain saws, lawn mowers, knapsack Small motors on brush trimmers, power-driven sprinklers, motor-driven blowers, dust collectors, hedge trimmers, etc., also to engine starters powered by such batteries, and also to motor-starters equipped with such Manual working machines for engine starters. Background technique [0002] Most engine starting devices for small air-cooled petrol engines fitted to the increasing use of manual work machines such as bush trimmers and chainsaws include: recoil drive sections; The clutch is connected to the driven section of the engine crankshaft; and the buffer / power storage section arranged between the driving section and the driven section, the buffer / power storage section is used to buffer the ...
