Abstract
A centrifugal separator (FIG. 1) has a base adapted to be mounted to a surface of a machine, such as an engine, with internally communicating high pressure liquid lubricant supply and low pressure drain passages. The base includes a control valve to inhibit supply to the rotor via spindle so that the cover and rotor can be removed whilst the base is still connected to the source of high liquid pressure. The valve takes the form of an aperture containing a valve body rotatable by handle to close the supply passage or (FIG. 2) create a diversion passage directly to the drain passage. An interlock device may be provided to impede cover removal with the valve open and/or impede accidental closure of the valve.
