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.

A particle separator for use in a pressurized three-phase flow system to separate debris particles from liquids and or gases and to segregate them for subsequent removal comprising: a housing having a top end cap, a smooth inner cylindrical wall, and a bottom, together defining a chamber therein; a fluid inlet constructed to tangentially inject fluid into said housing near the top end cap and to cooperate with said housing such that when the fluid is injected through the fluid inlet it impinges on the inner cylindrical wall in a manner such that a downwardly directed spiral flow pattern is developed, said flow pattern generating a centrifugal force field which firstly causes the entrapped gases to coalesce substantially in the center of said flow pattern and secondly propels debris particles to the outer reaches of said pattern for eventual separation, capture and removal; fluid removal means having a fluid outlet in the bottom of said housing, said bottom having a funnel-shaped surface on the interior thereof, the funnel-shaped surface extending from a wide mouth beginning near but spaced apart from the inner cylindrical wall and tapering to a narrower fluid channel communicating with the fluid outlet; means for maintaining the separation of debris particles from the fluid, extending upwards a short distance into the chamber from said mouth and forming an annular debris channel between the exterior surface thereof and the portion of the cylindrical inner wall immediately adjacent to the bottom, whereby debris particles are segregated and trapped in the debris channel for subsequent removal from the system; a debris exit comprising a debris outlet from the debris channel extending tangentially through the cylindrical inner wall, the debris exit being arranged for receiving separated debris particles after they have been propelled out of said flow pattern by the force field, and means for capturing debris particles, connected to said debris outlet.
