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。

摘要： A high pressure relief valve for use in a high pressure fluid pump is shown and described. In a preferred embodiment, a valve seat is provided with a tapered hole and with a conduit, the tapered hole and conduit being in fluid communication with each other and with fluid having a variable pressure. A tapered pin having grooves is held in the tapered hole by a control force, or control pressure acting through a plunger. When the pressure of the fluid is sufficiently high to overcome the control force or pressure, the tapered pin is forced to move sufficiently to create an annular clearance between the tapered pin and the tapered hole, thereby allowing pressurized fluid to flow past the pin to an outlet. An outer surface of the valve seat in a region of the tapered pin is tapered in an opposite direction to that of the tapered hole, thereby weakening the valve seat in that region, such that the tapered hole is able to expand and contract as the pressure of the fluid increases and decreases.

摘要： A low wear poppet valve in a high pressure reciprocating pump. Relative movement of the mating surfaces due to compressive distortion is eliminated. There is a valve seat having a flow passage and an upper mating surface, and a poppet element which sealingly abuts this. The flow passage is in communication with a low pressure zone, and the outer surfaces of the seat and element are in communication with a high pressure zone. The poppet element has a recess in its mating surface surrounded by a wall portion, and the low pressure zone is communicated from the flow passage into the interior of the recess. This enables the wall portion of the element to be displaced inwardly and outwardly in concert with the wall portion of the seat by the cyclic pressure differential which is generated between the zones by the operation of the pump. This eliminates relative movement between these parts which would otherwise cause fretting wear of their mating surfaces.

摘要： A method and apparatus for diagnosing components in high-pressure pumps to indicate when a component of the pump head is malfunctioning and to identify the malfunctioning component. In one embodiment, a high-pressure pump head incorporating a diagnostic system in accordance with the invention has a pressurization chamber and a pressurizing member at least partially received in the pressurization chamber. The pressurizing member moves within the pressurization chamber along an intake action to draw fluid into the pressurization chamber and along a pressurizing action to compress fluid in the pressurization chamber. An inlet fluid control assembly is coupled to the pressurization chamber to allow fluid to enter the pressurization chamber during the intake action, and a pressurized fluid control assembly is coupled between the pressurization chamber and an outlet chamber to selectively allow pressurized fluid into the outlet chamber during the pressurizing action. The pump head may also include a diagnostic system to indicate the operational status of each of the inlet fluid control assembly, the pressurized fluid control assembly and other components of the pump head upstream from the inlet fluid control assembly with respect to a fluid flow through the pump head during the pressurizing action.

The compression members each comprise a raised contact surface corresponding to the region of the body where the plurality of apertures meet, and through which the compressing bias is exerted. The fitting may be an elbow-fitting, a tee fitting, a cross-fitting, or some other configuration.

摘要： A high pressure fluid seal assembly is shown and described. The seal assembly includes a seal carrier having a bore through which a reciprocating pump plunger may pass, the seal carrier having a first annular groove concentric with the bore, and carrying an annular seal. The seal carrier further includes an integral annular guidance bearing positioned in a second annular groove of the seal carrier, the second annular groove and guidance bearing contained therein being axially spaced from the first annular groove and seal contained therein. An inner diameter of the guidance bearing is smaller than an inner diameter of the seal carrier in a region between the seal and the guidance bearing. The seal is therefore supported directly by the seal carrier, although the seal carrier is spaced from the reciprocating plunger by the guidance bearing. Frictional heating in the region of the seal is therefore reduced, thereby increasing the life of the seal. Materials for the plunger, seal and guidance bearing are selected to minimize friction between the plunger and seal and between the plunger and guidance bearing. Furthermore, the seal assembly is manufactured by pressing the guidance bearing into the seal carrier, and then machining the bore in the guidance bearing and in the seal carrier in the same setup, thereby improving the alignment of the elements and simplifying manufacturing.

摘要： High-pressure static seals and pressure vessels with static seals for containing fluid at high pressures are shown and described. Embodiments of the invention allow a plug to be easily, manually inserted into and removed from the pressure vessel. A metallic ring in the seal is configured to expand under pressure to prevent an O-ring in the seal from being extruded into a gap between the plug and the vessel wall, but not to expand so much as to cause galling or similar damage when the seal moves with respect to the wall under elevated pressure.
