I claim the ornamental design for a passive centripetal air/oil separator, as shown and described.
FIG. 1 is a perspective view of a centripetal air/oil separator, showing my new design in an assembled configuration;
FIG. 2 is an exploded perspective view of a first embodiment thereof;
FIG. 3 is a front elevational view of FIG. 1;
FIG. 4 is a rear elevational view of FIG. 1;
FIG. 5 is a right-side elevational view of FIG. 1;
FIG. 6 is a left-side elevational view of FIG. 1;
FIG. 7 is a bottom plan view of FIG. 1;
FIG. 8 is a top plan view of FIG. 1;
FIG. 9 is an exploded perspective view of a second embodiment thereof; and,
FIG. 10 is an exploded perspective view of a third embodiment thereof.
The three embodiments are understood to vary only with regard to an internal member that is visible only in the exploded view and partially through two inlet/outlet ports.
The broken line shown in the drawings are for the purpose of illustrating portions of the article that form no part of the claimed design.
