摘要： A carpet extractor includes a solution distributor, such as a spray bar 90, which delivers cleaning solution to a floor surface. A housing 10 selectively receives a recovery tank 22 for collecting dirty cleaning solution from the floor. A first tank 14 for concentrated cleaning fluid and a second tank 15 for clean water supply cleaning fluid and water to a reciprocating pump 420 through first and second fluid lines 412, 410. The pump includes a piston 428, which reciprocates between first and second ends of a cylindrical bore 430. A fluid line 432 interconnects the first and second fluid lines. As the pump reciprocates, a portion of the water is drawn into the interconnecting line during a downward stroke, where it mixes with the entering cleaning solution. As the pump moves on its upward stroke, the mixture is drawn back into the water line and is pushed onward by the pump toward the spray bar with each successive downward stroke.

摘要： A carpet extractor includes a base assembly 1 including a housing 10 which selectively receives a recovery tank 22 for collecting dirty cleaning fluid. A first supply tank 14 for concentrated cleaning fluid and a second supply tank 15 for clean water are mounted on an inverted Y-shaped handle assembly 12. The handle assembly includes a central member 334 with a hand grip 336 at its upper end and two splayed leg members 338, 342, 340, 344, which define a triangular shaped gap therebetween. The two tanks are removably mounted in the gap. The cleaning fluid tank is supported on a shelf 346, which spans the gap between the leg members. The water tank is pivotally mounted on two projections 374 on the leg members to allow for easy removal and replacement on the handle. The arrangement of tanks in the gap allows for large capacity tanks, a well-balanced handle, ease of removal of the recovery tank without the need for removing either of the two supply tanks, and ease of refill of the supply tanks.

摘要： A carpet extractor includes a base assembly 1 including a housing 10 which selectively receives a recovery tank 22 for collecting dirty cleaning fluid. A nozzle assembly 67 is mounted to the base housing and provides a fluid flowpath 182 for dirty cleaning fluid from the floor surface to the recovery tank. The nozzle assembly is pivotable from a first position, in which the fluid flowpath communicates with the recovery tank, to a second position, in which the nozzle assembly is spaced from the recovery tank to allow the recovery tank to be removed from the base housing. A second flowpath 138 is formed on the recovery tank between the tank and a nozzle plate 136. The flowpaths have openings 218, 140, respectively, at their lower ends, which are located either side of two longitudinally spaced brushrolls 60, 62. A flap valve 474 selectively closes both flowpaths during above floor cleaning.
摘要翻译： 地毯抽取器包括基座组件1，底座组件1包括壳体10，壳体10选择性地容纳用于收集脏的清洁流体的回收罐22。 喷嘴组件67安装到基座壳体上并且提供用于从地板表面到回收罐的脏的清洁流体的流体流动路径182。 喷嘴组件可从其中流体流动路径与回收罐连通的第一位置枢转到第二位置，在第二位置，喷嘴组件与回收罐间隔开，以允许回收罐从基座壳体移除。 第二流路138形成在容器和喷嘴板136之间的回收罐上。流路在其下端分别具有开口218,140，它们位于两个纵向间隔的刷卷60,62的两侧。 阀门474在地板清洁过程中有选择地关闭两个流路。
