摘要： A cleaning apparatus which is of a compact construction to facilitate easy manipulation and portability includes a housing enclosing a fluid pump and a vacuum fan and mounting upon opposite sides a recovery tank and a stowage panel. The stowage panel is adapted to stow the flexible wand having a nozzle when not in use. Also, the high voltage motor driving the vacuum pump is adapted to also act as half of a transformer in order to pick off the lower voltage needed for the low voltage motor driving the fluid pump.
摘要翻译：具有紧凑结构以便于操作和便携性的清洁装置包括封闭流体泵和真空风扇的壳体，并且在相对侧上安装有回收罐和收纳板。该装载板适于在不使用时收纳具有喷嘴的柔性棒。此外，驱动真空泵的高压电动机也适用于变压器的一半，以便去除驱动液体泵的低压电动机所需的较低电压。

摘要： A fluid flow control valve according to the invention includes a base, a valve member, a trigger member and attachment means for attaching the trigger member to the valve member. The base includes a generally horizontal throat and a flange having an upwardly facing surface. The valve member has a stem, a flow level establishing member associated with the stem and biasing means for biasing the stem in a direction opposite to that in which the throat extends. The trigger member includes a pin configured to rotate against an inner end portion of the throat, a flange having a downwardly facing surface and an actuating portion. The biasing means acts in a direction through the attachment means to pull the actuating portion downwardly such that the flanges engage in order to retain the pin in the throat. In this manner, the valve may be assembled without the use of fasteners.
摘要翻译：根据本发明的流体流量控制阀包括底座，阀构件，触发构件和用于将触发构件附接到阀构件的附接装置。底座包括大致水平的喉部和具有向上表面的凸缘。阀构件具有杆，与杆相关联的流量建立构件和用于沿与喉部延伸的方向相反的方向偏压杆的偏压装置。触发器构件包括构造成相对于喉部的内端部分旋转的销，具有朝下的表面和致动部分的凸缘。偏置装置沿着穿过附接装置的方向作用，以将致动部分向下拉动，使得凸缘接合以将销保持在喉部中。以这种方式，可以在不使用紧固件的情况下组装阀。

摘要： A liquid extraction surface cleaning apparatus has an upwardly opening recovery tank and a top for the tank which contains a suction fan having a suction inlet opening into the tank. A wand connects to a source of cleaning liquid and has a dispensing and pickup head that deposits liquid on the surface to be cleaned in response to actuation of a control valve and picks up dirty fluid. A water and air separator has an arcuate surface transverse of the flow path of the air and spent liquid which gently separates them into separate streams by diverting the cleaning liquid laterally away from the air stream. A shutoff valve for preventing recovered liquid in the tank from entering the suction fan is mounted in the recovery tank rather than to the suction inlet to avoid dripping dirty liquid onto the floor when the cover is removed. A handle is mounted internal the tank and additionally serves to strengthen the tank sidewalls.
摘要翻译：液体提取表面清洁装置具有向上开口的回收罐和用于罐的顶部，其包含具有到罐中的吸入口的抽吸风扇。魔杖连接到清洁液源并且具有分配和拾取头，其响应于控制阀的致动而将液体沉积在待清洁的表面上并拾取脏流体。水和空气分离器具有横向于空气和废液的流动通道的弓形表面，其通过将清洁液体横向偏离气流而将其轻轻分离成单独的流。用于防止储罐中的回收液体进入吸风机的截止阀安装在回收罐中而不是吸入口，以避免在盖子被移除时将脏液体滴落到地板上。手柄内部安装有手柄，另外还用于加强油箱侧壁。

摘要： A vacuum extractor has a tank assembly including an outer tank and a coaxial inner tank. The inner tank has an open top which is reversibly closed by a cover assembly which includes a vacuum source and a liquid pump. The cover assembly also includes a hose connection in communication with said inner tank and said vacuum source enabling said inner tank to receive either wet or dry materials. The outer tank is substantially closed having an input port closed by a closure member configured in the form of a measuring cup. The outer tank is used for containing a cleaning material which can be accessed through a hose which passes through an aperture in the outer wall of the tank. The hose has an external connector for supplying cleaning material to the liquid pump in the cover assembly which, in turn, supplies the cleaning material to a cleaning tool. The unit is supported by casters which are recessed into the bottom of the tank assembly. A pair of opposed caster recesses are shaped to provide handholds to assist in emptying the separate tanks. The inner tank can be emptied by pouring in a first direction while both inner and outer tanks can be emptied simultaneously by pouring in a second direction opposite to the first direction.
