    摘要： The present invention provides an upright vacuum cleaner (10) having an elongate body (12) and comprising a floorhead (14) on which the elongate body is mounted, the floorhead (14) having a first inlet (140) for dirty air, a wand having a second inlet for dirty air, a changeover valve (22) for selecting between a flow of dirty air from the first or second inlet, a dust collection chamber (18) also having a dirty air inlet (180), a duct (28) for conveying said flow of dirty air from the changeover valve (22) to the dust collection chamber inlet (180), and a source of suction power for drawing the dirty air from the first or second inlet through said changeover valve (22) and said duct (28) to the dust collection chamber inlet (180). The changeover valve (22) comprises a linear conduit (24) positionable in fluid flow between the first inlet (140) for dirty air of the floorhead (14) and said duct (28), the duct (28) having a sigmoid curve (30) from the changeover valve (22) to the dust collection chamber inlet (180). When the conduit (24) is positioned in fluid flow between the first inlet (140) and the duct (28), the flow of dirty air from the first inlet (140), through the changeover valve (22) and the duct (28) to the dust collection chamber inlet (180) all lies in a plane.

    摘要： A jigsaw (2) having a housing (4) and a jigsaw support shoe (16) is disclosed. A motor in the housing (4) causes reciprocating motion of a jigsaw blade, and causes a fan in the housing to emit air from the housing. Air is driven by the fan via a connector piece (22) and a bridge member (20) towards the jigsaw blade in a direction transverse to a line of cutting action of the jigsaw (2). An inlet of a suction tube, connected to a source of suction such as a vacuum cleaner, is provided on the opposite side of the jigsaw blade to the bridge member (20). Provision of a stream of air in a direction transverse to the line of cutting action of the jigsaw (2) allows the outlet of the bridge member (20) to be located close to the jigsaw blade without obscuring the user's view of the location at which the blade cuts the workpiece, while the provision of an inlet to a suction tube on the opposite side of the jigsaw blade further constrains the stream of air to improve dust extraction.
