    Abstract: To enable centrifugal filtration of fluids which contain abrasive contaminant particles the rotor bearing (3) must be isolated from the fluid which passes into and through the rotor chamber (21). This is achieved by a design in which the spindle (4) is connected to the rotor so as to rotate in unison with the rotor )5, 6, 7) relative to the base (1). The bearings (3) for the spindle (4) are provided in a bearing housing (2) which is fixedly mounted to the base (1) and a sealing arrangement, preferably a spring-loaded axial seal (14, 15), is provided between the spindle (4) and the base (1) at a location below the bearings (3) in the bearing housing (2).

    Abstract translation: 为了能够对含有磨蚀性污染物颗粒的流体进行离心过滤，转子轴承（3）必须与进入和通过转子室（21）的流体隔离。 这通过其中主轴（4）相对于基座（1）连接到转子以便与转子（5,6,7）一致地旋转的设计来实现。 用于主轴（4）的轴承（3）设置在固定地安装到基座（1）的轴承壳体（2）中，并且提供密封装置，优选地具有弹簧加载的轴向密封件（14,15） 在轴承壳体（2）中的轴承（3）下方的位置处在主轴（4）和基座（1）之间。

    Abstract: A self-powered centrifugal separator comprises a base (10), a rotor (11) mounted on an operably substantially vertical axis (12) for rotation thereabout by reaction to fluid emission from nozzles in the base, a housing (13) mounted on the base and enclosing the rotor, a sump (14) formed in the base (10) below the rotor (11), a fluid passageway (16) through the base extending from an inlet port (17) to an outlet port (18) and including a diversion port (19) to supply fluid to the interior of the rotor (11) by way of the rotation axis (12), and a drain passage (15) in the base for draining fluid from the sump (14) to the fluid passageway (16). A spring loaded valve body (30) is provided in the fluid passageway (16) and is configured and arranged to shut off supply of fluid to the interior of the rotor (11) when pressure of fluid entering the inlet port (17) falls below a predetermined minimum pressure value so that an engine to which the fluid is supplied as lubricating fluid is not at risk of damage. The valve body (30) is also configured and arranged (at 38, 39) to restrict and/or shut off supply of fluid to the interior of the rotor (11 ) when pressure of fluid entering the inlet port (17) rises above a second predetermined pressure value so that the rotor speed cannot be increased so much that there is risk of damage to the separator itself. Furthermore, a Venturi arrangement is provided in the fluid passageway (16) to develop suction pressure to draw fluid from the drainage passage into the fluid passageway and said Venturi arrangement (40) is conveniently provided integrally with the valve body (30). A non-return formation (50) to prevent back flow of fluid from the outlet port (18) may also be advantageously provided as part of the valve body (30).
