    • Parallel tube type, gasoline powered, blower/vacuums with improved versatility are provided. In one possible feature, a flapper throttle adjacent to the housing for controlling the engine is pivotable from side-to-side with respect to an elongate handle. The elongate handle is sufficiently long to allow a plurality of gripping positions, while the flapper throttle is sufficiently long to allow the operator to access the flapper throttle from different gripping positions on the handle. In another possible feature, a pivotable lever throttle is provided at an interface of the handle forward portion and a transverse grip portion at the handle forward portion end. The lever throttle has a first end accessible to the operator when gripping the transverse grip portion, and a second end accessible to the operator when gripping the handle forward portion. In another possible feature, a blower/vacuum is provided with a rear handle that increases blower/vacuum versatility in that the operator has a plurality of gripping choices available to him.
    • 提供平行管式,汽油动力,提供多功能性的鼓风机/真空吸尘器。 在一个可能的特征中,与用于控制发动机的壳体相邻的挡板节流阀可相对于细长的把手从一侧到另一侧枢转。 细长手柄足够长以允许多个抓握位置,而挡板节流阀足够长以允许操作者从手柄上的不同夹持位置进入挡板节流阀。 在另一个可能的特征中,可枢转的杠杆节流阀设置在手柄向前部分的接口处,并且在手柄前部端部处设置有横向抓握部分。 杠杆节流阀具有在抓握横向抓握部分时操作者可接近的第一端,以及当抓握手柄前部时操作者可接近的第二端。 在另一个可能的特征中,鼓风机/真空机设置有后把手,其提高鼓风机/真空多功能性,因为操作者具有可用于他的多个夹紧选择。

    • A blower is provided having a plurality of tubular nozzles removably attachable to the blower enabling an operator to easily vary the velocity and air discharge pattern. The blower forms part of an operator carried power tool having a drive motor spaced from the blower assembly by a tubular boom containing a drive shaft. The blower comprises a blower housing having an axial air inlet and an air outlet defined by a tubular section. An impeller is pivotally mounted within the blower housing and driven by the drive shaft. As the impeller is rotated, air is drawn through the air inlet and discharged through one of a plurality of tubular nozzles mounted on the blower housing tubular section. Tubular nozzles have varying geometries to conveniently vary the discharge air pattern.
    • 提供鼓风机,其具有可拆卸地附接到鼓风机的多个管状喷嘴,使得操作者能够容易地改变速度和空气排放模式。 鼓风机形成操作者承载的动力工具的一部分,该工具具有驱动马达,该驱动马达通过包含驱动轴的管状悬臂与鼓风机组件隔开。 鼓风机包括具有轴向空气入口和由管状部分限定的空气出口的鼓风机壳体。 叶轮枢转地安装在鼓风机壳体内并由驱动轴驱动。 当叶轮旋转时,空气通过空气入口抽出并通过安装在鼓风机壳体管状部分上的多个管状喷嘴中的一个排出。 管状喷嘴具有不同的几何形状以方便地改变排出空气模式。
