摘要： A pressure enclosure includes a first component having an opening, a second component coupled to the first component in a position over the opening, a third component positioned between the first and second components and covering the opening, and a load chamber defined by a space between the second and third components and configured such that pressure in the load chamber biases the third component against the first component to seal the opening. The pressure enclosure may be a cylinder of a pump for pressurizing fluid or gas, with the first component a cylinder body, the second component an end cap and the third component a valve body, with the load chamber biasing the valve body against the cylinder body.

摘要： A fitting for collecting or distributing high-pressure fluid via fluid transmission lines is provided. The fitting includes a body, and a plurality of apertures formed in the body in a common plane, intersecting inside the body such that all of the apertures are in mutual fluid communication. Each of the apertures is configured to receive a threaded coupling member of a respective high-pressure transmission line. The fitting also includes first and second compression members positioned on opposing sides of the body and coupled thereto so as to exert a compressing bias to the body in an axis perpendicular to the common plane. 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 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： An apparatus and method for pressure processing a pumpable substance, such as a pumpable food product or slurry. In one embodiment, the apparatus includes a pressure vessel having an inlet valve toward one end and outlet valve toward the other end. A flexible bladder is coupled between the inlet and outlet valves for receiving the pumpable substance. The pressure vessel can further include a high-pressure inlet port for receiving high-pressure fluid that biases the membrane inwardly to pressure process the pumpable substance. The pumpable substance is then removed from the vessel through the outlet valve.

摘要： A method and apparatus for biasing a seal assembly in a high pressure fluid pump. In one embodiment, the fluid pump includes a reciprocating plunger, a seal carrier disposed about the plunger, and a seal supported by the seal carrier and sealably engaged with the plunger. The seal may be biased toward the seal carrier with a spring and may include a flange that engages the spring to restrict lateral motion of a spring relative to the reciprocating plunger. The flange may engage an inner and/or an outer surface of the spring. Where the spring is a coil spring, the flange may be continuous around the circumference of the spring or may include a plurality of spaced apart projections located around the circumference of the spring.

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： 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.

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。
