    • An improved mechanical seal assembly is provided for sealing rotating shafts with respect to their shaft housings, wherein the rotating shafts are subject to substantial axial vibrations. The mechanical seal assembly generally includes a rotating sealing ring fixed to the shaft, a non-rotating sealing ring adjacent to and in close contact with the rotating sealing ring for forming an annular seal about the shaft, and a mechanical diode element that applies a biasing force to the non-rotating sealing ring by means of hemispherical joint. The alignment of the mechanical diode with respect to the sealing rings is maintained by a series of linear bearings positioned axially along a desired length of the mechanical diode. Alternative embodiments include mechanical or hydraulic amplification components for amplifying axial displacement of the non-rotating sealing ring and transferring it to the mechanical diode.
    • 提供改进的机械密封组件用于相对于它们的轴壳体密封旋转轴,其中旋转轴受到显着的轴向振动。 机械密封组件通常包括固定到轴的旋转密封环,与旋转的密封环相邻并紧密接触的非旋转密封环,用于围绕轴形成环形密封;以及机械二极管元件,其施加偏压 通过半球形接头对非旋转密封环施力。 机械二极管相对于密封环的对准由沿着机械二极管的期望长度轴向定位的一系列直线轴承来维持。 替代实施例包括用于放大非旋转密封环的轴向位移并将其转移到机械二极管的机械或液压放大部件。

    • Provided is a mechanical seal, in which a pressing mechanism configured such that two bellows expand and contract in accordance with fluid pressure inside an annular sealed space that is formed by the two bellows is included, that enables downsizing in a radial direction. A mechanical seal (100) is configured such that an annular sealed space (S1) is formed by a first bellows (141), a second bellows (151), and members respectively provided on both end sides of the first bellows (141) and the second bellows (151), and that the first bellows (141) and the second bellows (151) expand and contract in a central axial direction of a rotating shaft (200) in accordance with fluid pressure inside the sealed space (S1). The first bellows (141) and the second bellows (151) are arranged at positions distant to each other in the central axial direction, and are arranged such that a part of the first bellows (141) on a radially inward side and a part of the second bellows (151) on a radially outward side overlap when viewed in the central axial direction.

    • A water pump, in particular for application in the cooling system of a combustion engine for a car, equipped with a housing (1) with a space for fluid (2) which contains a pump device (3). The latter is placed on a shaft (4) which projects outside of the housing (1), and rotates while being supported by a bearing assembly (6) with a stationary outer ring (11) mounted on the housing (1). The fluid space (2) is sealed in relation to the shaft (4) by means of a sealing unit (7) equipped with a first ring (13) connected to the shaft (4), and a stationary second ring (14) mounted on the outer ring (11) of the bearing assembly (6). These rings (13-14) are equipped with sealing surfaces (15-16) which face one another or are about axial, and which are adjacent and sealed in relation to one another, whereby the first ring (13) is loaded by a spring device (17) in the direction of the second ring (14). The first ring (13) is placed on the shaft (4) by means of an elastic dampening and centering element (23) located between the inner circumference of this ring (13) and the outer circumference of the shaft (4), and distributed over the circumference of the shaft (4).
