摘要： A continuous, self-cleaning, rotary filtering apparatus is provided having a plurality of filter elements within a rotatable filter housing adapted for rotation between an inlet plate having an inlet manifold and an outlet plate having an outlet manifold so that the liquid to be filtered is passed from the inlet manifold through the filter elements and into the outlet manifold. The apparatus is further provided with a backflushing capability whereby the filter housing can be rotated to position where one filter element in alignment with a backflush port independent of the inlet manifold so that a part of the liquid within the outlet manifold will be caused to flow backward through that filter element and backflush port to purge contaminants from the apparatus via the backflush port without interrupting liquid flow through the other filter elements. After backflushing, the filter housing is further rotated to return the backflushed filter element to service.

摘要： A rotary diverter valve for use in diverting fluid wherein the fluid port intersections between the valve body and rotary element are all at a flat planar interface to provide a flat, zero clearance, metal to metal contact. Live bolting is provided to adjust the contact pressure through a spherical bearing arrangement as will tolerate axial misalignment due to nonparallel loading to eliminate any need for critical torquing and widen manufacturing tolerances and reduce costs. When utilizing a replaceable transition plate between the rotary element and the valve body, wear on costly components is eliminated, and the valve is easy to maintain and repair.
摘要翻译：用于转向流体的旋转分流阀，其中阀体和旋转元件之间的流体端口相交处都处于平坦的平面界面，以提供平坦的，零间隙的金属与金属的接触。提供活动螺栓以通过球面轴承装置来调节接触压力，这将允许由于不平行的负载引起的轴向不对准，以消除对临界扭矩的任何需求并且扩大制造公差并降低成本。当在旋转元件和阀体之间使用可更换的过渡板时，消除了昂贵部件上的磨损，并且阀易于维护和修理。
