20100059000 | ARRANGEMENT RELATED TO A MOTOR-DRIVEN TOOL - An arrangement for cleaning of intake air for an air-cooled internal combustion engine of a motor-driven tool, such as a chain saw. The arrangement includes an air conductor surrounding a fan wheel arranged to propel intake air around an axis of the fan wheel. An inner wall of the air conductor is arranged for guiding air propelled by the fan wheel. An air nozzle for cleaning of intake air is arranged on the inner wall of the air conductor radially close to said fan wheel. The air nozzle serves as a passage way for providing cleaned intake air from the fan wheel to the engine of the motor-driven tool, wherein the air nozzle and the air conductor are manufactured in one piece. | 03-11-2010 |
20110308831 | BATTERY POWERED TOOL AND BATTERY PACK FOR A BATTERY POWERED TOOL - A battery pack for powering a battery powered tool may include a housing, a plurality of cells and an electrical connection assembly. The housing may include a sidewall assembly. The sidewall assembly may be configured to correspond to respective sidewalls of a battery compartment defined at a portion of the battery powered tool to facilitate insertion of the battery pack into the battery compartment. The plurality of cells may be disposed within the housing and arranged adjacent to each other such that the sidewall assembly, which extends along a direction substantially parallel to a direction of insertion of the battery pack into the battery compartment, forms an enclosure around the plurality of cells on all sides substantially parallel to the direction of insertion. The plurality of cells may be electrically connected to each other to provide a combined output. The electrical connection assembly may be disposed at a portion of the sidewall assembly to communicate the combined output to a connector disposed at a corresponding sidewall of the battery compartment. The electrical connection assembly may be arranged to engage the connector responsive to movement of the battery pack in a direction substantially parallel to the direction of insertion of the battery pack into the battery compartment. | 12-22-2011 |
