摘要： A self-venting seal assembly for use in an ultrahigh-pressure pump is shown and described. In a preferred embodiment, a low-pressure seal is used to energize a high-pressure seal, the low-pressure seal having a "u" shaped cross-section, thereby creating a groove in a first end of the low-pressure seal. When the first end of the seal 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, which would act against a second end of the seal when the pressure on the opposite side of the seal drops, the seal compresses inwardly, thereby allowing the pressurized fluid to flow back past the seal.In a preferred embodiment, the high-pressure seal comprises a sleeve seal having an annular opening through which the plunger reciprocates, the sleeve seal being supported by a backup ring, the backup ring also having an annular opening through which the plunger passes. The sleeve seal and backup ring are configured such that they may be placed in an annular bore of a seal carrier and an annular end surface of the sleeve seal and an annular surface of the backup ring abut each other and are substantially flush, thereby simplifying manufacturing and installation of the seal assembly.
摘要翻译：示出并描述了用于超高压泵的自排气密封组件。在优选实施例中，使用低压密封来激励高压密封件，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，从而基本上防止流体经过它的泄漏。在任何加压流体确实泄漏通过密封件的情况下，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。在优选实施例中，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面中，并且支撑环的环形表面彼此邻接并且基本上齐平，从而简化制造并安装密封组件。

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.
