摘要： A mechanical seal 10 provides a fluid tight seal between relatively rotatable elements such as a drive shaft and a housing. The seal includes first and second seal faces (13, 11) and transmission means (27) which engage said second seal face and extend axially therefrom in a direction away from said first seal face. Biasing means (28) bias the transmission means, and thereby the second seal face, towards the first seal face. Drive means (29) engage the transmission means and are for mounting in driving engagement with the second element. The drive means include at least one radially extending engagement portion (30) which extends into an axially enclosed opening (31) in the transmission means.

摘要： A mechanical seal has an axially floating seal face (21) in sliding contact with an axially stationary seal face (22). A biasing means (33), such as a magnet, biases the floating seal face towards the stationary seal face. The axially floating seal face and the biasing means are rotationally fixed relative to each other and the axially stationary seal face is free to rotate relative to the axially floating seal face. The seal may be used, for instance, as a bearing protector or isolator.

摘要： An isolator seal includes a stator member for placement into the stator of rotating equipment and a rotor member for placement onto a rotary shaft of the rotating equipment. The stator member and the rotor member provide respective adjacent surfaces, while a static shut-off device engages both adjacent surfaces when the rotor member is static and disengages one or more of the surfaces when the rotor member is dynamic. In one embodiment of the invention at least one of the surfaces is inclined to the longitudinal axis at an angle greater or less than 90°. In a further embodiment, the static shut-off device includes a resilient annular sealing member and an auxiliary member, which can move between a first position, when the rotor member is static, at which the auxiliary member compresses the resilient annular member into engagement with both surfaces, and a second position at which the compression on the resilient member is reduced, so that the resilient annular member disengages one or more of the rotor and stator surfaces when the rotor is dynamic.

摘要： An isolator device, which may be a bearing seal or a bearing isolator, for use hindering fluid flow between components which are rotating relative to each other about a longitudinal axis, the flow being in one direction parallel to this axis, includes a stator for securing to a rotary fixed one of the components and a rotor for securing to a relatively rotating one of the components. The stator has a surface which extends longitudinally and adjacent to a surface of a component, which rotates relative to the stator. The fluid flow is between the two surfaces and the stator surface is non-parallel to the adjacent component surface and is shaped to promote fluid flow in a direction opposing the general fluid flow direction.
