View Patent ↗An oil and air separator includes a lower housing defining in part a chamber within which oil may collect; an upper housing including a lower end threadingly engaged to an upper end of the lower housing; and a filter assembly threadingly engaged to the upper housing; wherein a lower portion of the filter assembly is disposed within the chamber when the filter assembly is threadingly engaged to the upper housing and the upper housing is threadingly engaged to the lower housing; wherein the filter assembly includes a filter block including a plurality of parallel lumens extending through the block; and wherein a continuous fluid pathway exists through the oil and air separator, the continuous fluid pathway extending from a fluid inlet port disposed in the upper housing, downward through a first passageway about the filter assembly, into the chamber, through a lower end of the filter assembly, upward through the plurality of parallel lumens extending through the filter block, through an upper end of the filter assembly, and through a second passageway leading to a fluid outlet port disposed in the upper housing.
1. An oil and air separator including:
(a) a lower housing defining in part a chamber within which oil may collect;
(b) an upper housing including a lower end threadingly engaged to an upper end of the lower housing; and
(c) a filter assembly threadingly engaged to the upper housing;
wherein a lower portion of the filter assembly is disposed within the chamber when the filter assembly is threadingly engaged to the upper housing and the upper housing is threadingly engaged to the lower housing;
wherein the filter assembly includes a filter block including a plurality of parallel lumens extending through the block; and
wherein a continuous fluid pathway exists through the oil and air separator, the continuous fluid pathway extending from a fluid inlet port disposed in the upper housing, downward through a first passageway about the filter assembly, into the chamber, through a lower end of the filter assembly, upward through the plurality of parallel lumens extending through the filter block, through an upper end of the filter assembly, and through a second passageway leading to a fluid outlet port disposed in the upper housing.
2. An oil and air separator including:
(a) a lower housing defining in part a chamber within which oil may collect;
(b) an upper housing including a lower end threadingly engaged to an upper end of the lower housing; and
(c) a filter assembly threadingly engaged to the upper housing;
wherein a lower portion of the filter assembly is disposed within the chamber when the filter assembly is threadingly engaged to the upper housing and the upper housing is threadingly engaged to the lower housing;
wherein the filter assembly includes a filter block including a plurality of parallel lumens extending through the block;
wherein a continuous fluid pathway exists through the oil and air separator, the continuous fluid pathway extending from a fluid inlet port disposed in the upper housing, downward through a first passageway about the filter assembly, into the chamber, through a lower end of the filter assembly, upward through the plurality of parallel lumens extending through the filter block, through an upper end of the filter assembly, and through a second passageway leading to a fluid outlet port disposed in the upper housing; and
wherein the filter assembly includes a collar threadingly engaged to the upper housing at an upper end of the collar and a lower cap threadingly engaged to the collar at a lower end of the collar.
3. The oil and air separator of claim 2 , wherein a first portion of the filter block is disposed within the collar and a second portion of the filter block is disposed within the lower cap.
4. The oil and air separator of claim 3 , wherein a screen is disposed between the filter block and the lower cap.
5. The oil and air separator of claim 4 , wherein the chamber is in fluid communication with an oil exit port through which oil may be removed from the chamber.
