Cyclonic system for separating debris particles from fluids

Abstract

This invention discloses a particle separator adapted for use in a pressurized lubrication system for mechanical drives to separate debris particles from the fluid. Fluid tangentially injected into the housing impinges on the inner cylindrical wall in a manner which develops a downwardly directed spiral flow pattern, which generates a centrifugal force which firstly causes the entrapped gases to coalesce substantially in the center of the flow pattern and secondly selectively propels debris particles to the outer reaches of the pattern where the debris particles are segregated and trapped in a debris channel for subsequent removal from the system. A debris exit extends tangentially through the cylindrical wall. Apparatus for detecting and indicating the presence of debris particles, e.g. a magnetic particle detector, eddy current sensor, or optical particle detector, is preferably connected to the debris outlet. Outlets for the injected fluid and separated gases are also provided.
