Crankcase filter assembly
A filter assembly that includes a separator for separating gas from a fluid. The assembly includes; a base with surrounding walls that define a fluid reservoir; a baffle that overlies at least a portion of the reservoir; a filter element that is beneath the baffle and in the reservoir; and, a cover that is removably fastened to the base and includes a fluid inlet that terminates in a conical base with an unrestricted opening and the baffle includes a fluid impact cone.
1. A filter assembly comprising:
a base with surrounding walls and a recessed fluid reservoir;
a filter element that is positioned within the recessed fluid reservoir;
a baffle with a filter facing surface and a cover facing surface and the filter facing surface overlies at least a portion of the filter element and has a plurality of apertures that are open to the filter element;
the baffle has a depression that is open on the cover facing surface and closed on the filter facing side;
a removable cover that is fastened to the base, the cover has a fluid inlet tube that overlies the depression in the baffle to form a separator;
whereby a fluid entering the fluid inlet tube impact the depression in the baffle and the fluid is separated into liquid and gas and the liquid is returned to the reservoir through the plurality of apertures wherein: the baffle depression is a conical recess that has a semicircular wall on the cover facing surface, and an upstanding ring that is concentric with the semicircular wall; and, the removeable cover has a concentric section of a perimeter wall that is concentric with the semicircular wall on the upper surface of the baffle.
2. The filter assembly of claim 1 , wherein the baffle has a plurality of pin receiving apertures and the cover has a plurality of pins that are arranged to engage with a respective aperture among the plurality of apertures in the baffle in releasable press fits.
3. A gas from liquid separator comprising:
a base with surrounding walls that define a recessed filtering element receiving space within the surrounding walls;
a baffle with an outer perimeter that overlies at least a portion of the recessed space and at least a portion of the filtering element, and has a plurality of apertures;
the baffle includes a closed recess that is spaced from the recessed filtering element receiving space and is surrounded by an upstanding ring and a concentric semicircular wall of an outer perimeter of the baffle; and,
a removable cover that has a plurality of pins that are arranged to engage with a respective aperture among the plurality of apertures in the baffle and an open base;
whereby the baffle and the cover form a gas from liquid separator wherein the recess of the baffle is coaxial with the open base of the cover, and the closed recess of the baffle terminates in a flat lower end.
4. The separator of claim 3 , wherein
the removable cover has an outer perimeter wall and the baffle has a semicircular wall that mesh with each other to define a separator position.
