摘要： A filter apparatus having a filter element and a stop valve, both incorporated in a body thereof. By means of an engagement, the stop valve is coupled with a cap which is fitted to a body of the filter apparatus by thread-engagement. When the cap is removed from the body for replacement of the filter element, the stop valve rotates together with the cap to close an inlet port of the filter apparatus. On the other hand, when the cap is fitted to the filter apparatus, the stop valve directs the fluid into the filter apparatus since an opening provided in the stop valve coincides with the inlet port because of rotation of the stop valve.

摘要： A method and apparatus for automatically propelling a charge of backwash fluid by a compressed gas such as steam to backwash a filter in a filter pair. The method and apparatus provides for backwashing a filter with at least three backwash phases, a first mainly comprising a charge of backwash fluid passing through the filter with significant speed, a second relating to use of flashing steam for secondary cleaning and scrubbing of the filter elements, and a third relating to use of low pressure steam for autoclaving and sterilizing the filter.

摘要： A system is provided for feeding a process or bath with a high purity liquid and when needed upgrading or maintaining the purity of such liquid when delivered from a bulk shipping container. In the system, the liquid in which a high degree of purity is desired is pumped through a filter and sensor which detects the level of particulates while maintaining the integrity of the product against contamination. The purity of the liquid is upgraded by pumping, i.e., recirculating, the liquid through a filtration media while sensing the purity, and returning the processing liquid when the desired level of purity is reached. A gas vent filter is used to purify air or vapor passing into or out of the system avoids pressure or vacuum buildup.

摘要： First and second identical filters (6, 20) are connected in series. A backpressure unit (30) for intermittent backwashing is connected to the outlet from the second filter. Means are provided for measuring or setting the pressure P.sub.1 at the inlet to the first filter, the backpressure P.sub.2, the pressure P.sub.3 of the liquid between the two filters and the pressure P.sub.4 at the outlet from the second filter. Means (34) determine A=P.sub.1 -2P.sub.3 +P.sub.4, and B=(K/2N)(P.sub.2 -2P.sub.1 +P.sub.4), where K and N are constant coefficients, and a circuit (35) causes the backpressure unit to apply backpressure for backwashing when A=B. This amounts to comparing conditions in the first and second filters and triggering backwashing only when required, thereby avoiding wasting time with too frequent backwash operations, or conversely with dismantling and regenerating the filters due to too infrequent backwashing leading to clogging that cannot be cleaned by backwashing. The filter is particularly applicable to filtering organic liquids, such as milk, wine or beer.
摘要翻译：第一和第二相同的滤波器（6,20）串联连接。用于间歇反冲洗的背压单元（30）连接到来自第二过滤器的出口。提供了用于测量或设定第一过滤器入口处的压力P1，背压P2，两个过滤器之间的液体的压力P3和来自第二过滤器的出口处的压力P4的装置。装置（34）确定A = P1-2P3 + P4，以及B =（K / 2N）（P2-2P1 + P4），其中K和N是常数系数，并且电路（35）使背压单元施加背压用于A = B时的反冲洗。这相当于比较第一和第二过滤器的条件，仅在需要时触发反冲洗，从而避免浪费时间，反复进行过多的反冲洗操作，或者相反，由于过于少量的反洗而导致过滤器的拆除和再生，导致无法通过反冲洗清洗的堵塞。过滤器特别适用于过滤有机液体，如牛奶，葡萄酒或啤酒。

摘要： A self-cleaning filter device comprises a fluidic oscillator having a pair of passages through which fluid is directed alternately, and filter elements which fluid can flow from said passages to an auxiliary outlet. A main outlet communicates with the passages in such a way that the filter elements do not impede fluid flow to the main outlet. Between each passage and the main outlet is a device which provides a higher impedance to flow from the main outlet to the passages than to flow in the opposite direction, and assists the self-cleaning action of the filter elements by increase the difference between the fluid pressures in the passages.

摘要： Coaxial bidirectional flow control and relief valves are provided especially suited for use in hydrostat systems containing a filter or filters interposed between a pump and a hydraulic motor, to direct flow in one direction through a filter, and to direct flow in the opposite direction to bypass the filter. The valves are space-saving, can be kept closed under low biasing forces, and can be made light in weight, affording a low-mass valve that can be moved in milliseconds from a closed to an open position. The valves can control not only bidirectional forward and reverse flow paths but also a relief path for flow to bypass a filter which is clogged.
摘要翻译：提供同轴双向流量控制和安全阀，特别适用于含有介于泵和液压马达之间的过滤器或过滤器的液压稳定系统，以使一个方向上的流动通过过滤器，并引导相反方向流动以绕过过滤器。这些阀节省空间，可以在低偏压力下保持关闭，并且可以使其重量轻，从而提供可以在从闭合到打开位置的毫秒内移动的低质量阀。阀门不仅可以控制双向正向和反向流动路径，而且可以控制用于绕过被堵塞的过滤器的流动的释放路径。
