摘要： A rotary shaft sealing assembly in which a first fluid is partitioned from a second fluid in a housing assembly having a rotary shaft located at least partially within. In one embodiment a lip seal is lubricated and flushed with a pressure-generating seal ring preferably having an angled diverting feature. The pressure-generating seal ring and a hydrodynamic seal may be used to define a lubricant-filled region with each of the seals having hydrodynamic inlets facing the lubricant-filled region. Another aspect of the sealing assembly is having a seal to contain pressurized lubricant while withstanding high rotary speeds. Another rotary shaft sealing assembly embodiment includes a lubricant supply providing a lubricant at an elevated pressure to a region between a lip seal and a hydrodynamic seal with a flow control regulating the flow of lubricant past the lip seal. The hydrodynamic seal may include an energizer element having a modulus of elasticity greater than the modulus of elasticity of a sealing lip of the hydrodynamic seal.

摘要： The present invention is a hydrodynamically lubricated interference type rotary shaft seal suitable for environmental exclusion and high pressure lubricant retention which incorporates an environment-side groove to control and minimize interfacial contact pressure at the dynamic sealing interface, which permits optimum hydrodynamic film thickness, thereby significantly lowering the self-generated heat produced by the seal, as compared to the prior art. The cool-running nature of the present invention permits the use of higher modulus seal materials and higher surface speeds, compared to the prior art, and allows the seal to operate in applications with relatively poor heat dissipation. The controlled interfacial contact pressure of the present invention also permits effective hydrodynamic lubrication with lower viscosity lubricants, including water.

摘要： A non-locking tapered plug valve is provided which prevents taper locking of the plug member by ensuring against pressure responsive plug movement toward the small extremity thereof due to positive or negative hydraulic pressure transients. The chambers at each axial extremity of the plug member are of such volumetric relation during positive pressure transients that the chamber at the small extremity of the plug reaches equilibrium with flow passage pressure before the chamber at the large extremity of the plug member thus ensuring that any pressure responsive resultant force acting on the plug member is directed toward its large extremity. To avoid taper locking during a negative pressure transient, an equalization passage with a check valve is provided to permit unidirectional flow from the large extremity of the valve chamber to the main flow passage. This allows a quicker equalization of pressure between the large extremity of the valve chambers with line pressure, whereas the higher pressure in the small extremity of the valve chamber creates a force on the plug member away from the taper locking direction.
摘要翻译：提供一种非锁定的锥形旋塞阀，其通过确保由于正或负液压瞬变而抵抗压力响应插塞向其小端移动而防止插塞构件的锥形锁定。插塞构件的每个轴向末端处的室在正压力瞬变期间具有这样的体积关系，即在塞子的大端部处的腔室之前，在塞子的小端部处的腔室与流动通道压力达到平衡，从而确保任何作用在插塞构件上的压力响应合成力指向其大的末端。为了避免在负压瞬变期间的锥形锁定，设有具有止回阀的均衡通道以允许从阀室的大端到主流道的单向流动。这允许在具有管线压力的阀室的大末端之间更快地平衡压力，而阀室的小端部中的较高压力在插塞构件上产生远离锥形锁定方向的力。

摘要： A hydrodynamically lubricating seal has a generally circular seal body defining a static sealing surface and having a dynamic sealing lip projecting from the seal body for establishing sealing relation with a relatively rotatable surface. When compressed against a relatively rotatable surface, dynamic sealing lip defines a hydrodynamic geometry which wedges a film of lubricating fluid into the interface between the seal and the relatively rotatable surface in response to relative rotation. The dynamic sealing lip geometry maintains interfacial contact pressure within the dynamic sealing interface for efficient hydrodynamic lubrication and environmental exclusion, which enhances lubrication and environmental exclusion while permitting relatively high initial compression and relatively low torque. In abrasive environments, the improved exclusionary action results in a dramatic reduction of seal and shaft wear, compared to prior art, and provides a significant increase in seal life. The invention also increases seal life by making higher levels of initial compression possible, compared to prior art, without compromising hydrodynamic lubrication. This added compression makes the seal more tolerant of compression set, abrasive wear, mechanical misalignment, dynamic runout and manufacturing tolerances.
摘要翻译：流体动力学润滑密封件具有限定静态密封表面的大致圆形的密封体，并且具有从密封体突出的动态密封唇，用于与相对可旋转的表面建立密封关系。当相对于相对旋转的表面压缩时，动态密封唇限定了响应于相对旋转将润滑流体膜楔入密封件和相对可旋转表面之间的界面的流体动力学几何形状。动态密封唇几何形状保持动态密封界面内的界面接触压力，以实现有效的流体动力学润滑和环境排除，从而增强润滑和环境排除，同时允许相对较高的初始压缩和相对较低的扭矩。在磨蚀性环境中，改进的排除动作导致与现有技术相比，密封和轴的磨损大大降低，并且密封寿命显着增加。本发明通过与现有技术相比可以实现更高水平的初始压缩而不损害流体动力学润滑来提高密封寿命。这种增加的压缩使得密封件更容忍压缩永久变形，磨损磨损，机械失准，动态跳动和制造公差。

摘要： A drilling head for the controlled operation of the drill string while diverting well fluids from the well. The drilling head incorporates a kelly drive and at least one stripper rubber which rotate with the drill string extending through the drilling head. Rotation of the drive bushing and stripper rubber are controlled by bearings disposed in a bearing chamber of the drilling head through which lubricant is circulated to reduce friction and cool the bearings. A turbine ring attached to the lock nut ring of the kelly drive circulates lubricant through the bearing chamber as it rotates in association with the drive assembly of the drilling head. The turbine pump ring forces circulation of lubricant as the drive assembly rotates in addition to the circulation by the remove lubricant pump or in the event the remote pump fails to operate. The turbine ring includes a plurality of angular slots to force circulation of the lubricant as the drive assembly rotates.

摘要： A hyrodynamic lubricant sealing element for devices such as rotary cone rock bits, shaft seals and the like which is maintained under sufficient mechanical compression to effect a seal between relatively movable structures. The sealing element defines a sealing surface establishing a seal interface with a relatively movable circular sealing surface and forms a lubricant interface and a contaminant interface at opposite sides thereof. The lubricant interface is of such configuration as to induce a hydrodynamic lubricant wedging activity causing migration of lubricant film in the seal interface from the lubricant interface to the contaminant interface for flushing away any contaminant and for lubrication between the sealing element and sealing surface. The contaminant is of a configuration developing substantially no such hydrodynamic wedging activity at the contaminant interface and yet presenting a scraping edge to remove contaminant material from the sealing surface upon relative axial movement of the sealing surface and sealing element.

摘要： The present invention is directed to a rotary shaft seal assembly and, more particularly, to an assembly including a continuous, annular, but axially variable seal for providing hydrodynamic lubrication between the seal and rotating shaft. The seal assembly uses differential pressures to maintain the seal compressed as it wears. The present system is particularly useful in drilling motors utilizing the movement of drilling fluid under pressure to operate the motor parts and thereby to drive a drill bit. The abrasive drilling fluid environment in a borehole is detrimental to the moving parts in such a system, and especially destructive to the bearings and seals. The present system utilizes a sealing member arranged in a continuous, annular, but axially variable path between the rotating shaft and housing of such a motor. Annular seal mounting members are positioned above and below the seal and have surfaces to matingly engage the seal member. The mounting elements are arranged to move relative to one another. A pressure differential developed across the motor is communicated to the respective mounting elements to urge the elements toward one another and thereby compress the seal member therebetween to accommodate wear take-up on the seal member. An oil chamber above the upper mounting element communicates drilling fluid pressure inside the drill pipe to the upper mounting element. The pressure of the annular space below the motor housing is communicated to the lower mounting element by means of a lower chamber.
