  • Low noise package storing type engine working machine
    Patent number: 6463905
    Abstract: An engine working machine formed by storing a radiator and a cooling fan, for leading heat exchange air for the radiator, in a package together with an engine and a working machine. Wherein a storage space for the engine and working machine is separate from a ventilating port, which communicates with a space between the radiator and the cooling fan. The space is shielded by partitions from an air leading space to which air is led after being passed through the radiator by the cooling fan. A cooling air leading port for externally cooling the engine and the working machine is formed in a part of the package so that outside air led from the cooling air leading port passes the storing space and is exhausted from the ventilating port to the air leading space, to which air is led after having passed through the radiator.
