摘要： An improved apparatus for generating a high-pressure fluid jet includes an orifice mount (11) having a frusto-conical surface (12) that engages a frusto-conical wall in a cutting head (22), the geometry of the orifice mount (11) and cutting head (22) being selected to increase the stability of the mount and reduce deflection of the mount adjacent a jewel orifice (20), when subjected to pressure. Alignment of a nozzle body (37) and the cutting head (22) is improved by providing pilot diameters both upstream and downstream of threads on the nozzle body (37) and bore (23) of the cutting head, respectively. Accurate placement of a mixing tube(49) in a cutting head is achieved by rigidly fixing a collar (52) to an outer surface of the mixing tube (49), the collar engaging a shoulder (34) and bore of the cutting head downstream of a mixing chamber (33), to precisely locate the mixing chamber (33) axially and radially.

摘要： A self-venting seal assembly (10) for use in an ultrahigh-pressure pump is shown and described. In a preferred embodiment, a low-pressure seal (26) is used to energize a high-pressure seal (34), the low-pressure seal (26) having a "u" shaped cross-section, thereby creating a groove (32) in a first end of the low-pressure seal (26). When the first end (28) of the seal (26) is exposed to pressurized fluid, it expands outwardly thereby substantially preventing the leakage of fluid past it. To the extent that any pressurized fluid does leak past the seal (26), which would act against a second end (30) of the seal (26) when the pressure on the opposite side (28) of the seal (26) drops, the seal (26) compresses inwardly, thereby allowing the pressurized fluid to flow back past the seal (26). In a preferred embodiment, the high-pressure seal comprises a sleeve seal (34) having an annular opening (36) through which the plunger (14) reciprocates, the sleeve seal (34) being supported by a backup ring, the backup ring (38) also having an annular opening (40) through which the plunger (14) passes. The sleeve seal (34) and backup ring (38) are configured such that they may be placed in an annular bore (17) of a seal carrier (11) and an annular end surface (44) of the sleeve seal (34) and an annular surface (42) of the backup ring (38) abut each other and are substantially flush, thereby simplifying manufacturing and installation of the seal assembly (10).
摘要翻译：使用低压密封件来对高压密封件通电，低压密封件具有“u”形横截面，从而在低压密封件的第一端中形成凹槽。当密封件的第一端暴露于加压流体时，其向外膨胀，从而防止流体经过其泄漏。在任何加压流体泄漏通过密封件的程度上，当密封件的相对侧上的压力下降时，该密封件将作用于密封件的第二端，密封件向内压缩，从而允许加压流体回流经过密封件密封。高压密封件包括具有环形开口的套筒密封件，柱塞往复运动，套筒密封件由支撑环支撑。支撑环还具有柱塞通过的环形开口。套筒密封和支撑环被构造成使得它们可以被放置在密封载体的环形孔和套筒密封件的环形端表面中，并且支撑环的环形表面彼此邻接并且基本上齐平。

摘要： An apparatus (10) to remove rubber from airplane tires from an airport runway surface (28). There is a manifold arm (24) which rotates at as high as two thousand five hundred rpms over the runway surface (28), with a plurality of water jets (26) being discharged downwardly at a relatively high pressure (e.g. thirty five thousand P.S.I.) against the runway surface (28). Even though the water pressure as at a level several times higher than that at which damage to the runway surface (28) can occur, at the relatively high linear speed of the water jets (26) (e.g. ninety to one hundred eighty miles per hour), there is no noticeable damage to the runway surface (28), but yet there is quite effective removal of the accumulated rubber. Also disclosed is a particular shaft and seal assembly which is capable of operating at relatively high rotational speeds and delivering the high pressure to the manifold arm (24).

摘要： A fitting (120) for collecting or distributing high-pressure fluid via fluid transmission lines is provided. The fitting (120) includes a body (122), and a plurality of apertures (124) formed in the body (122) in a common plane, intersecting inside the body (122) such that all of the apertures (124) are in mutual fluid communication. Each of the apertures (124) is configured to receive a threaded coupling member of a respective high-pressure transmission line. The fitting (120) also includes first and second compression members (132) positioned on opposing sides of the body (122) and coupled thereto so as to exert a compressing bias to the body (122) in an axis perpendicular to the common plane. The compression members (132) each comprise a raised contact surface (135) corresponding to the region of the body (122) where the plurality of apertures (124) meet, and through which the compressing bias is exerted. The fitting (120) may be an elbow-fitting, a tee fitting, a cross-fitting, or some other configuration.
