Abstract
Abstract A method of separating the constituents of a fluid where the constituents have different physical characteristics including mass, weight, coefficient of friction and the like. The method comprising impeding the flow of the fluid for causing the fluid to move in a curvilinear path. By moving in a curvilinear path, the fluid is effected by centrifugal forces. The centrifugal forces cause the separation of the constituents of the fluid. Further, the effected fluid is slowed for further enhancing separation of the constituents of the fluid.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
193 words
A method of separating more dense constituents of a fluid from less dense constituents of a fluid, a housing is provided having a first end, a second end, a wall there between and an inlet in the wall adjacent the first end, the housing comprising therein an exterior chamber and an interior chamber separated by a conical baffle, the conical baffle arranged in the housing such that the exterior chamber decreases in volume from the first end to the second end of the housing, the method comprising the steps of: (a) impeding the flow of the fluid accepted in the exterior chamber of the housing via the inlet and causing the fluid to move in a curvilinear path by the fluid striking the conical baffle such that the fluid is effected by centrifugal force which force enhances the separation of the fluid constituents, and (b) reducing the centrifugal force by the fluid migrating from the first end of the housing to the second end of the housing such that the fluid moves into a portion of the exterior chamber having increasing volume to further enhance the separation of the constituents of the fluid.
Claim 2
Independent Claim

A method of separating more dense constituents of a fluid from less dense constituents of a fluid, a housing is provided having a first end, a second end, a wall there between and an inlet in the wall adjacent the first end, the housing comprising therein an exterior chamber and an interior chamber separated by a conical baffle, the conical baffle arranged in the housing such that the exterior chamber decreases in volume from the first end to the second end of the housing, the method comprising the steps of: (a) impeding the flow of the fluid accepted in the exterior chamber of the housing via the inlet and causing the fluid to move in a curvilinear path by the fluid striking the conical baffle such that the fluid is effected by centrifugal force which force enhances the separation of the fluid constituents, and (b) reducing the centrifugal force by the fluid migrating from the first end of the housing to the second end of the housing such that the fluid moves into a portion of the exterior chamber having increasing volume to further enhance the separation of the constituents of the fluid.
Claim 3
Dependent Claim
42 words
The method as defined in claim 1 further comprising the step of decelerating the fluid such that the more dense fluid constituents move in a radial direction with respect to the centrifugal force and in a downward direction with respect to gravity.
