    摘要: Arrangement in a blower including at least an engine and a fan, the fan includes a fan housing enclosing a fan wheel and a fan inlet. The engine and fan are surrounded by a casing provided with an air inlet to let air in to the fan inlet placed inside the casing. The air stream from the air inlet in the housing to the fan inlet cools the engine and components inside the casing before it enters the fan inlet and leaves the blower via a blower tube. The fan housing is provided with an opening (31) placed in the fan housing so that air is allowed to leave the fan in case of blocked air stream in the fan outlet or blower tube.

    摘要: Conventional leaf blowers have a supporting frame to where the different components are attached. In order to reduce the noise from the tool and protect some of the components are they provided with covers. This makes the tool heavy and complicated for the operator to use. The claimed invention is a covering casing (10) that also is the supporting structure for the different components in the tool. The casing reduces the amount of noise spread from the tool and protects the components inside the casing (10).

    摘要: Conventional leaf blowers that are carried on the back of the operator have a starting device placed outside an engine and an fan which means that there position will be far from the back of the operator. This position of the starting device makes it difficult for the operator to reach it and results in that the center of gravity for the tool will be far from the back of the operator. The position also means that the operator must take the tool down from the back to be able to start the tool. In this application is a new arrangement that solves the above-described problem claimed. This is done by placing the starting device (20) for the engine (11) on the side of the fan that is facing towards the back of the operator when the leaf blower is in its right position on the back of the operator. This moves the center of gravity closer to the back of the operator and makes it possible for the operator to reach the starting device without removing the tool from the back.
