摘要： A nozzle for producing an ultrahigh-pressure fluid fan jet is shown and described. In a preferred embodiment, the nozzle has an inner surface defined by a conical bore extending from a first end to a second end, thereby creating an entrance orifice and an exit orifice in the first and second ends, respectively. A wedge-shaped notch extends inward from the second end towards the first end to a sufficient depth such that the shape of the exit orifice is defined by the intersection of the conical bore and the wedge-shaped notch. As pressurized fluid passes through the nozzle and out the exit orifice, the shape of the exit orifice causes the pressurized fluid to exit in the form of a fan jet having a substantially oval cross-section. This fan jet may be swept across a surface to be cleaned thereby selectively removing a layer of material from an underlying surface evenly and completely, without damaging the underlying surface. The fan jet may also be used to cut a fibrous or hard material.

摘要： A seal assembly for a high pressure pump where there is an O-ring positioned in a seal groove having side seal surfaces and a back seal surface, with said O-ring being exposed alternately to high and low pressures in the pumping chamber. A pressure relief passageway is provided to the O-ring at a side surface portion thereof to provide pressure relief at the back side of the O-ring and thus alleviate unwanted fluid accumulation behind the O-ring, thus extending the longevity of the O-ring.

摘要： A seal assembly having a backup ring through which a piston reciprocates. There is a seal sleeve made of a non-abrading, extrusion resistant material that surrounds the piston at a location forwardly of the backup ring. The backup ring has an opening to receive the piston, and the opening is formed to define a radially and rearwardly expanding gas between the piston and backup ring to receive and discharge any seal material which may extrude into the gap. There is a positioning flange integral with the backup ring that surrounds the seal sleeve to press the seal sleeve into engagement with the piston, and there is an outer seal portion to form a seal between the positioning flange (or the outer portion of the backup ring) and the cylinder.

摘要翻译：示出并描述了用于生产超高压流体风扇喷嘴的喷嘴。在优选实施例中，喷嘴具有由从第一端延伸到第二端的锥形孔限定的内表面，从而在第一端和第二端分别形成入口孔和出口孔。楔形凹口从第二端朝向第一端向内延伸到足够的深度，使得出口孔的形状由锥形孔和楔形凹口的交点限定。当加压流体通过喷嘴并离开出口孔时，出口孔的形状使得加压流体以具有基本上椭圆形横截面的风扇喷射器的形式离开。该风扇喷射器可以扫过待清洁的表面，从而均匀且完全地从下面的表面选择性地去除一层材料，而不会损坏下面的表面。风扇喷嘴还可用于切割纤维或硬质材料。
