Patent number: 9517555Abstract: A battery operated handheld power tool, comprising a working tool assembly (20), a handle assembly (10) and an elongate tubular rod (30). The working tool assembly (20) comprises a motor housing (26) having a first inner space (27), comprising an electric motor (21) with a fan (25). The first inner space (27) is connected to the exterior of the working tool assembly (20) by means of at least one air outlet (28). The handle assembly (10) comprises a second inner space (19) in which a control unit (15) is positioned, the second inner space (19) being in flow communication with the exterior of the handle assembly (10). The elongate tubular rod (30) defines an air guiding channel (33), in flow communication with the first inner space (27) and the second inner space (19).Type: GrantFiled: October 27, 2011Date of Patent: December 13, 2016Assignee: HUSQVARNA ABInventors: Mikael Racov, Henrik Hvitman, Peter Gunnarsson

Patent number: 7185393Abstract: Leaf blower that is carried on the back of the operator comprising at least an engine (14) and a fan. The fan is provided with an air inlet (13) placed on the side of the fan that is facing away from the back of the operator. The air stream is passing the engine (14) on its way to the air inlet (13) so that the engine (14) is cooled.Type: GrantFiled: May 6, 2002Date of Patent: March 6, 2007Assignee: Aktiebolaget ElectroluxInventors: Göran Dahlberg, Gustaf Döragrip, Peter Gunnarsson, Marcus Kragner, Anna Sjögren, Esbjörn Ollas

Patent number: 7174991Abstract: The subject invention refers to a muffler comprising a muffler housing (1, 2) and generally a catalytic converter element (13) mounted in the housing, which muffler has at least one inner outlet (4) through which exhaust gases cleaned by the catalytic element (13) are intended to pass. Furthermore, according to the invention an outlet duct (30, 31) is arranged in connection to the outside of the housing, comprising a first section (30) for leading exhaust gases in a first direction (A) in parallel with the outside of the housing, and a second section (31) for leading exhaust gases in a second, opposite direction (B), whereby said first and second sections (30, 31) have an essentially equally large cross-sectional area. By way of this outlet duct an improved cooling of the exhaust gases before they are brought in contact with fresh air rich in oxygen can be achieved. A back-pulsation of fresh air into the muffler can also be prevented.Type: GrantFiled: November 3, 2000Date of Patent: February 13, 2007Assignee: Aktiebolaget ElectroluxInventors: Peter Gunnarsson, Esbjörn Ollas, Mattias Ossiansson

Patent number: 7159691Abstract: 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).Type: GrantFiled: May 8, 2002Date of Patent: January 9, 2007Assignee: Aktiebolaget ElectroluxInventors: Göran Dahlberg, Gustaf Döragrip, Peter Gunnarsson, Marcus Kragner, Anna Sjögren, Esbjörn Ollas
