    • A fluid jetting apparatus, such as nozzle, includes a support on which an orifice member is rotatably mounted. Orifices in the member are eccentric so that fluid exiting the orifices gives a driving force to rotate the orifice member relative to the support. To prevent the member from rotating too fast, a magnetic flux is provided to induce eddy currents in the support or the orifice member to produce a resisting torque opposing the speed-increasing torque resulting from the force of the fluid exiting the orifices. The eddy currents arise in response to relative motion between the magnetic flux and either the orifice member or the support.
    • 诸如喷嘴的流体喷射装置包括其上可旋转地安装有孔构件的支撑件。 构件中的孔眼是偏心的,使得离开孔的流体产生使孔口构件相对于支撑件旋转的驱动力。 为了防止构件旋转太快,提供磁通以在支撑件或孔口构件中引起涡流,以产生抵抗由离开孔口的流体的力产生的增速扭矩的阻力扭矩。 响应于磁通量与孔口构件或支撑件之间的相对运动而产生涡流。

    • A self-contained cleaning system particularly suited for use with motor vehicles comprising a storage tank filled with cleaning fluid and containing a pump and a D.C. electric motor, a hose, and an external power cord, and a pistol shaped sprayer head. Depressing a trigger shaped control piece on the sprayer head opens a valve disposed therein and closes an electrical switch that activates the D.C. electric motor which drives the pump, sending cleaning fluid through the hose to the sprayer head. Cleaning fluid is emitted from one of several nozzles on a rotatable nozzle selector on the front of the sprayer head. A locking mechanism, which can hold the control piece in one of several pre-determined positions, along with a magnet in the base of the handle of the sprayer head enables hands free operation of the unit, with the sprayer head secured by the handle to a steel surface such as a car body. The 12 volt D.C. power required by the motor can come directly from a car's electrical system, connected with the external power cord, or dry cells stored in an internal compartment in the storage tank can be used.
    • 特别适合用于机动车辆的独立清洁系统,其包括填充有清洁流体并包含泵和直流电动机,软管和外部电源线的储罐以及手枪式喷雾头。 将喷发器头上的触发形状的控制件压下,打开设置在其中的阀,并关闭电动开关,该电开关激活驱动泵的直流电动机,将清洁流体通过软管送到喷雾头。 清洁流体从喷雾头前部的可旋转喷嘴选择器上的几个喷嘴中的一个喷出。 可以将控制件保持在几个预定位置之一中的锁定机构以及在喷雾器头部的手柄的基部中的磁体使得单元能够手动操作,其中喷雾头由手柄固定到 钢表面如汽车车身。 电机所需的12伏直流电源可以直接来自汽车的电气系统,与外部电源线连接,也可以使用储存在储罐内部的干电池。
