ENGINE-DRIVEN WORK MACHINE

Document Type and Number:

WIPO Patent Application WO/2006/077774

Kind Code:

A1

Abstract:

An engine-driven work machine, wherein an engine/work machine unit (5) and an exhaust muffler (23) are stored in a box (30), a cooling air flow passage (44) passing the periphery of the engine/work machine unit (5) and the exhaust muffler (23) is formed in the box (30), and a cooling fan (15) driven by an engine (2) is disposed in the cooling air flow passage (44). A cut-off means (51) cutting off the cooling air flow passage (44) between the engine (2) and the exhaust muffler (23) when the operation of the engine (2) is stopped is installed in the box (30). Thus, the heat of the exhaust muffler at a high temperature can be prevented from affecting the unit even when the operation of the engine is stopped while securing the sound insulating property of the box in which the engine/work machine unit is stored.
