    摘要： A back pack for carrying a gas operated blower. The back pack has a frame and straps for supporting the frame on the back of an operator. The frame has a dual wall construction forming an internal fuel storage tank. Thus, the blower does not need a separate fuel tank. This reduces the weight and cost of the back pack and blower.

    摘要： A hand held portable blower/vacuum assembly includes a gasoline engine mounted on a blower housing that is interchangeably operable as a blower or vacuum unit and is symmetrically arranged for right or left hand use. A U-shaped carrying handle is secured to an upper housing enclosing the engine by means of a mounting structure that includes anti vibration elements. For eliminating the effect of both gyroscopic and centrifugal forces, the engine is arranged with the piston and crankshaft in horizontal and vertical orientations respectively, while both exhaust and cooling air are discharged from the front of the unit away from an operator so as to provide a balanced unit operable with either the right or left hand. A multi-position throttle located on the backside of the unit removed from the handle is incrementally settable for operating the unit at preselected fixed speeds. The vacuum inlet is located on the underside of the housing and is generally closed by a hinged cover providing only for induction air flow when the unit is used in the blower mode. Included about the vacuum inlet is a connecting flange for attaching a vacuum intake tube when the cover is hingedly moved outward for using the unit in the vacuum mode. A discharge opening on the front side of the unit includes a connecting flange to which either a blower tube and nozzle can be attached for the blower mode or tubing and bag can be attached for the vacuum mode.

    摘要翻译： 手持便携式鼓风机/真空组件包括安装在鼓风机壳体上的汽油发动机，其可互换地用作鼓风机或真空单元，并且对称地布置用于右手或左手使用。 通过包括防振元件的安装结构将U型携带手柄固定到封闭发动机的上壳体。 为了消除陀螺和离心力的影响，发动机分别与活塞和曲轴分别布置在水平和垂直方向上，同时排气和冷却空气从操作者的前方排出，以便提供一个 平衡单元可以用右手或左手操作。 位于从手柄移除的单元的背面上的多位置节流器可递增地设定，以便以预选的固定速度操作该单元。 真空入口位于壳体的下侧，并且通常由铰接盖封闭，该铰接盖仅当在鼓风机模式中使用该单元时才提供感应空气流。 包括真空入口的是连接凸缘，用于在盖子铰接地向外移动以在真空模式中使用该单元时连接真空进气管。 在该单元前侧的排放口包括连接法兰，可将鼓风机管和喷嘴连接至鼓风机模式或管路和袋可连接到真空模式。
