摘要： A static seal is utilized to provide a fluid boundary in place of a dynamiceal during underwater storage. The static seal is formed by an O-ring disposed between a threaded collar and retainer. The collar is held in alignment with a shaft by means of slots so that the collar rotates with the shaft in either rotational direction but is capable of moving independent of the shaft in the axial direction. The collar is threaded to the retainer by turning the collar with respect to the retainer in a clockwise direction. This forms the O-ring static seal permitting underwater storage of an underwater vehicle for an extended period of time. Following storage the operation of the shaft in a counter-clockwise direction disengages the collar from the retainer thereby releasing the static seal so that the dynamic seal comes into utilization.
摘要翻译：在水下存储期间，使用静态密封来代替动态密封来提供流体边界。静密封由设置在螺纹轴环和保持器之间的O形环形成。轴环通过槽保持与轴对准，使得轴环沿轴线在任一旋转方向上旋转，但是能够在轴向方向上独立于轴移动。通过相对于保持器沿着顺时针方向转动套环将套环拧到保持器上。这形成了O型圈静态密封，允许水下航行器长时间水下存储。在存储之后，轴的逆时针方向的操作使轴环与保持器脱离，从而释放静态密封件，使得动态密封件得以利用。

摘要： A shaft coaxially mounted within a cylinder is sealed with respect to that cylinder by means of an annular carrier affixed to the shaft and having its periphery facing the inner wall of the cylinder provided with an annular seal groove having an inverted L-shaped cross section and receiving two circumferentially split, radially expandable seal rings, one of which is rectangular in cross section and another of correspondingly inverted L-shaped configuration, with the L-shaped seal ring having its sliding surface facing the cylinder inclined toward a radial side face thereof at an angle equal to or greater than the angular deflection of the sliding surface towards the inner wall of the cylinder due to the deflection of the seal ring about a circular line extending through the body of the L-shaped seal ring and defining a plane perpendicular to the axis of that seal ring, said deflection occurring as a result of resilient radial expansion and applied fluid pressure on the seal.

摘要： In a rotodynamic pump intended for operation at high pressures e.g. 2000 p.s.i. and for pumping contaminated fluids e.g. corrosive water, high pressure sealing assemblies are provided at the through-openings in the pump casing for the pump shaft. Each assembly includes a pair of axially spaced mechanical seals, and each seal comprises a rotor portion fixed to the pump shaft and a stator portion axially movable into sealing engagement with the rotor portion, the stators being located intermediate the rotor portions. A busing is located between the seals and includes conduits supplying oil at a pressure above pump pressure to the innermost seal whence the oil is reduced in pressure and passed to the outermost seal, so that oil is delivered to the facing ends of the stators. The oil serves for lubrication of the sealing interfaces and for the prevention of egress of contaminated material through said innermost seal.

摘要： An end face seal especially adapted for use in severe service environments such as for sealing track pins of crawler type tractors. The seal includes a primary annular seal, having a radially extending flange portion for contacting a mating surface in face sealing engagement and an axially extending flange portion, and a secondary annular sealing member positioned in use about the axial flange portion. The cross section of the secondary annular sealing member is generally parallelogram-shaped in an unstressed condition.

摘要： A sealing arrangement for a rotary regenerative air preheater that precludes the leakage of gas or air through the clearance space between a cylindrical rotor shaft and an end plate of a relatively fixed surrounding housing structure. The sealing arrangement includes an annular flange concentrically fixed at one end to the rotor shaft and adapted to extend into spaced relation with the housing structure to provide a clearance space therebetween. The clearance space is adapted to carry a plurality of discrete bands of packing material with a pressurized air seal therebetween to resist the flow of fluid therethrough, while the annular flange is subjected to wear and attrition that would otherwise be imposed upon the rotor post.

摘要： A seal or packing engages a rotary machine part, e.g. a shaft, to be sealed off. Lubricant is drawn into the extended sealing area between the seal and the machine part and retained therebetween as a packing fluid, when the machine part rotates, regardless of the direction of rotation. Two or more sealing rings in tandem can be used as a self-lubricating packing ring or slide bearing.

摘要： A lip seal for use between two relatively-rotating surfaces, and in which the contact pressure increases with distance from the sealing lip for preventing the leakage of fluid therebetween irrespective of the direction of relative rotation. The seal has projections on the "air" side of the sealing lip (that is to say, the side remote from the fluid to be sealed) which so engage one of the relatively-rotating surfaces as to have a contact area of which two opposite sides extend away from the sealing lip portion and diverge away from each other.

摘要： An oil seal capable of pumping oil lying on a shaft or like member axially of the shaft upon rotation thereof into the sealed region. In a preferred form, the seal includes an elastomeric body having a primary lip and a plurality of individual pumping elements, an auxiliary lip which extends between elements. In the preferred form, the pumping elements are of wedge-like form and are being radially spaced relative to one another and thereby adapted for successive operative engagement with an associated shaft or other relatively movable element only after a certain amount of wear has taken place with respect to certain of the other of the elements. The auxiliary lip ordinarily lies in a plane parallel to the primary lip. In the use of the preferred form of seal, as the elements lying closer to the movable element wear and become less effective to pump oil, other of the elements will inherently be brought into cooperative working engagement with the movable element in order to provide continued pumping action throughout an extended life of the seal unit. The secondary or auxiliary lip restrains fluid from passing axially too far away from the primary lip and prevents oil from collecting on the elements. The auxiliary lip concept may also be applied to seals having other forms of pumping elements. The mold core and method of making it are also described.
摘要翻译：一种油封，其能够在其轴向旋转时将位于轴上的轴或类似构件的油泵送到密封区域中。在优选形式中，密封件包括具有主唇缘和多个单独泵送元件的弹性体，在元件之间延伸的辅助唇缘。在优选形式中，泵送元件是楔形的并且相对于彼此径向间隔开，并且因此仅在经过一定量的磨损发生之后才与相关联的轴或其它可相对移动的元件连续地操作地接合，尊重某些其他元素。辅助唇通常位于与主唇平行的平面中。在使用优选形式的密封件时，随着靠近可移动元件的元件磨损并且变得不太有效地泵送油，其他元件将固有地与可移动元件协调工作接合，以便提供持续的泵送在密封单元的整个使用寿命期间的作用。次级或辅助唇缘限制流体轴向通过离开主唇缘的太远，并防止油在元件上收集。辅助唇缘概念也可以应用于具有其它形式的泵送元件的密封件。还描述了模芯及其制造方法。
