Abstract:
1. A self-powered centrifugal separator, comprising: a base having an inlet port and an outlet port; a housing detachably mounted on said base, said housing and said base defining a closed fluid chamber therein; a rotor arranged within said chamber and rotatably mounted and supported in said chamber for rotation about a substantially vertical axis for rotation thereabout by reaction to fluid emission from rotor nozzles, said housing and base enclosing said rotor, said rotor including a sump formed in said housing chamber at said base in an axial position below said rotor, said sump receiving fluid from said rotor; a fluid passageway arranged in said base and extending between and fluid flow interconnecting said inlet port and said outlet port to communicate fluid flow between said inlet and said outlet ports; a diversion port arranged in said base and operable to communicate fluid flow between said fluid passageway into said interior of said tubular rotation axis component to supply fluid to the interior of said rotor a drain passage arranged in said base and operable to communicate fluid flow between said sump and said fluid passageway, said drain passage for draining fluid from said sump; a spring loaded valve body including a venturi arrangement arranged in said fluid passageway of said base, said venturi arrangement including a nozzle restriction within said fluid passageway operable to develop suction pressure to draw fluid from said drainage passage into said fluid passageway; wherein said moveable valve body is hollow forming a moveable valve body fluid flow passage within said moveable valve body extending from a first end of said moveable valve body to an opposing second end of said moveable valve body, wherein said moveable valve body fluid flow passage opens into said fluid passageway of said base to receive said fluid flow from said inlet port at a first end of said moveable valve body, and wherein said venturi arrangement is provided integrally with said moveable valve body at an opposing second end of said moveable valve body.
