摘要： Disclosed is a labyrinth seal assembly for sealing an annular gap defined between a bore of a housing and an outer surface of a cylindrical shaft, wherein the housing and shaft are relatively movable. The seal assembly includes radially inner and radially outer shield rings. The radially inner shield ring has an inner surface which is adapted and configured for support by the shaft. The radially outer shield ring is partially disposed within the sealing channel of the inner shield ring. The outer shield ring includes a casing member, foam seal elements, and a shield element retainer. The foam seal elements depend radially inward into the sealing channel so as to form a circuitous sealing labyrinth therein. The seal elements are formed preferably from polyurethane. A highly viscous fluid is disposed within the circuitous sealing labyrinth.

摘要： A seal system is provided for a bearing. The bearing includes a housing having two sides and a bearing element disposed within the housing. The bearing element is disposed to facilitate motion of a rotating shaft. The seal system includes a seal carrier which is adapted to be mounted on the bearing housing. The seal carrier has a groove in an inner periphery wherein a seal is disposed within the seal carrier groove. The seal has a soft flexible lip which contacts the rotating shaft. A groove is formed in an outer periphery of the seal for receiving a retaining device. The seal and the seal carrier are mountable on either side of the bearing even when the two sides experience dissimilar environments such as vacuum on one side and a liquid spray on the other. The seal and/or the seal carrier may be split for facilitating simpler in-field installation.

摘要： A seal arrangement for a shaft having a broad rpm range, supported in a housing, in particular for axle drives. A radial shaft seal, arranged in the housing bore hole, seals the shaft bearing space from loss of lubricant. A baffle plate, joined to the shaft, and having a lip seal, is aligned radially to the inside, which under the effect of centrifugal force lifts off from its sealing surface at higher rotational speeds of the shaft.

摘要： A rotating connection device forming a seal between an inner element (1) and an outer element (14) of larger diameter than the inner element, these two elements being co-axial, cylindrically symmetric and rotating in relation to one another. It comprises a shell (16) placed in the annular space between the two elements, at least a first ring-type seal (19) secured to the shell, placed between the latter and inner element (1), at least a second ring-type seal (23) placed between two opposite walls (22, 18) of shell (16) and of outer element (14), both perpendicular to the axis of rotation, and means (24-26) for pressing the two walls against one another by means of the ring-type seal with an adjustable application force. This connection device allows substantial motions between the two elements, radial as well as longitudinal. The device can be used: for example for connecting a pipe linking an outer device and the central part of the rotating ring gear of a heat exchange and/or incineration system.

摘要： A rocket engine shaft seal which prevents leakage from escaping from the pump to the turbine along the shaft 1. The seal has a bellows spring 8 for pushing the floating ring seal 2 into contact with the mating ring 4 when the rocket engine is off, thus sealing the liquid in the pump section more reliably. When the engine is on, the pressure of the fuel will overcome the force of the bellows spring 8, moving the floating ring seal 2 away from contact with the mating ring 4, so as to save wear on the face contact portion 5 of the floating ring seal and preserve a good seal when the engine is off. The floating ring seal 2 has an inner diameter 11 for forming a seal with the shaft 1. The shaft 1 may have a labyrinth on it for forming a labyrinth seal with the floating ring seal 2, or with the floating ring seal and the bellows adapter's arm portion 13 for forming a longer labyrinth seal.

摘要： The choke arrangement comprises an elastic choke ring which consists of a single piece with a gap formed by a parting joint. The choke arrangement: further comprises a support ring which is arranged directly adjacent to the choke ring in the axial direction, with the support ring serving, among other things to cover over the gap of the choke ring. An advantage of the choke arrangement with an elastically resilient choke ring is to be seen wherein the choke ring reacts to dynamic pressure changes and thereupon changes its sealing properties. A peak in pressure produces an increased difference in pressure at the choke arrangement, whereby the elastic choke ring is pressed against the sliding surface of a piston rod and effects an increased sealing action, so that the pressure peak cannot propagate to a sealing ring placed after the choke arrangement. The choke arrangement thus behaves analogously to a frequency selective filter known from electrical engineering in that high-frequency pressure changes are sealed off, whereas static or slowly varying pressure components are not sealed off.
摘要翻译：扼流装置包括弹性阻风圈，其由具有由分离接头形成的间隙的单件构成。扼流装置还包括一个支承环，该支撑环在轴向方向上直接邻近扼流圈布置，其中支撑环用于覆盖扼流环的间隙。可以看到具有弹性弹性阻塞环的扼流装置的优点在于其中扼流环对动态压力变化作出反应，并随后改变其密封性能。压力峰值在扼流装置处产生增加的压力差，由此弹性阻风圈被压靠在活塞杆的滑动表面上并且产生增加的密封作用，使得压力峰值不能传播到放置在窒息安排。因此，扼流装置类似于从电气工程已知的频率选择滤波器，其中高频压力变化被封闭，而静态或缓慢变化的压力分量不被密封。

摘要： The regulator connects to a high pressure fluid supply and regulates the pressure to a downstream apparatus. If an over-pressure occurs, it is vented to atmosphere. A segmented body reduces production cost. An elongate control stem engages a supply seal assembly and a vent seal assembly and moves axially with respect to these seal assemblies to achieve regulation and venting. Both the supply seal assembly and the vent seal assembly are bi-directional and operate when forces are applied from opposing directions.

摘要： A segmented labyrinth seal assembly and method according to which a plurality of arcuate segments extend around a rotating shaft with the shaft being engaged by a sealing portion of each segment, thus sealing against the movement of fluid in an axial direction along the shaft. An engagement member extends from one end of at least one segment and is adapted to engage the corresponding end of the adjacent segment. The engagement member is urged in a direction towards the corresponding end to apply a separation force between the ends, and the separation force is adjustable.
