    摘要： An airflow indicator for a vacuum cleaner includes a housing, a wheel chamber defined in the housing, and a rotatable wheel mounted in the wheel chamber. The wheel has protrusions which cause the wheel to rotate due to inlet air flow. The wheel further has markings which gradually increase in size along an outside perimeter of the wheel. The markings indicate movement of the wheel. An air inlet is formed adjacent a first end of the housing. An air passageway is formed within the housing adjacent the rotatable wheel and the air inlet. The air passageway is curved to facilitate air flow along the protrusions of the wheel. A valve is mounted within the housing adjacent the air passageway. The valve has a cross slit which opens in response to a change in vacuum pressure. An air outlet is formed in the housing. A window portion partially encloses the wheel within the wheel chamber. The window allows viewing of the wheel from outside of the housing.

    摘要翻译： 用于真空吸尘器的气流指示器包括壳体，限定在壳体中的轮室，以及安装在车轮室中的可旋转轮。 车轮具有突起，导致车轮由于入口气流而旋转。 轮子还具有沿车轮外周逐渐增大的标记。 标记表示车轮的运动。 在壳体的第一端附近形成空气入口。 在壳体内邻近可旋转轮和空气入口形成空气通道。 空气通道弯曲以便于沿着轮的突起的空气流动。 阀门安装在靠近空气通道的壳体内。 阀具有响应于真空压力变化而打开的横切口。 空气出口形成在壳体中。 窗部分将车轮部分地包围在车轮室内。 窗户允许从外壳的外部观察车轮。

    摘要： A hand-held vacuum cleaner includes a housing, a suction fan and a first motor assembly located in the housing and a dirt container detachably mounted on the housing. A suction nozzle is selectively mounted on the housing and is usable both in an attached position and in a detached position for cleaning. A brushroll and a second motor are mounted within the suction nozzle. An electrified hose is connected to the housing and to the suction nozzle. The dirt container includes an inlet in fluid communication with the electrified hose, and an outlet in fluid communication with the suction fan and first motor assembly. A filter assembly is releasably positioned for form an outlet of the dirt container. The dirt container has a latching mechanism for securing the dirt container to the housing. The housing further includes a hollow section formed above the suction fan and first motor assembly for storing a cleaning attachment.

    摘要： A control disk insert for a one lever mixer valve (20) contains two preferably, planar disks, whereof one fixed control disk (24) has at least one opening zone for hot water and at least one opening zone for cold water. The movable control disk (22) facing the fixed control disk (24) and movable with two degrees of freedom can both completely close and continuously completely open the opening zones in the fixed control disk (24). The opening zones of the fixed control disk (24) and the opening zones of the moveable control disk (22) are constructed in such a way that the control disk (22) can be positioned to divert a non-contaminated fluid stream to a separate outlet for connection to various devices. Or, the opening zones of the fixed control disk (24) and the opening zones of the moveable control disk (22) are constructed in such a way that the control disk (22) can be positioned to send a pressure signal or pressure relief signal to an appliance.
