摘要： A centrifugal blower includes a main scroll portion and a scroll opening through which air is discharged. A transitional portion conducts air discharged through the scroll opening away from the blower. The transitional portion includes an internal passageway that provides for the smooth passage of air essentially without causing any abrupt changes in the direction of the flow of the air through the passageway. An impeller assembly can be mounted within the main scroll portion for rotation so as to circulate the air in a spiral path within the main scroll portion and force the air through the scroll opening and the passageway in the transitional portion. The impeller assembly can have a platen that has a perimeter and a plurality of impeller blades mounted at the platen for rotation with the platen. Each impeller blade can have a distal end that extends beyond the perimeter of the platen.

摘要： A tool with an engine, a shaft, and a recoil starter pulley coupled to the shaft for rotation about an axis. A starter pull rope for winding and unwinding around the recoil starter pulley. An air chamber shroud extending about at least a portion of the pulley, the rope extending from the pulley through the shroud. A tube enclosing a portion of the rope and extending from a location adjacent to and aligned with the pulley to a location at an exterior of the shroud that is axially offset from the pulley. The tube may have flared ends to reduce gradual wear of the rope. The tube alters a trajectory of the pull rope to be substantially offset from the plane of the starter pulley so as to avoid interfering with neighboring structures inside the tool.
摘要翻译：具有发动机，轴和反冲启动轮的工具，其联接到轴以围绕轴线旋转。用于在反冲起动滑轮周围卷绕和放卷的起动器拉绳。围绕滑轮的至少一部分延伸的气室护罩，绳索从滑轮延伸穿过护罩。包围绳索的一部分并且从与皮带轮相邻并与其对准的位置延伸到护罩外部位于轴向偏离皮带轮的位置处的管。管可以具有扩口端以减少绳索的逐渐磨损。管改变了拉绳的轨迹，以使其基本上偏离起动滑轮的平面，以避免与工具内的相邻结构的干扰。
