Abstract: A filtration apparatus has a housing that has a main housing body and a base closure member. The base closure member is releasably attached to the main housing body, wherein the housing defines an enclosed space. A filter element is disposed in the enclosed space. The housing has a fluid inlet and a fluid outlet. The base closure member has a peripheral channel extending about an entire periphery of the base closure member, wherein the peripheral channel is in communication with the fluid inlet or the fluid outlet of the housing. The base closure member has a fluid inlet passage and/or a fluid outlet passage communicating with the peripheral channel and communicating with the filter element.

Abstract: A rotor (40) for a centrifugal separator (20) used for separating solid contaminants from pressurized engine lubricant, is driven by pressure of the lubricant, a portion of which is directed to, and expelled from rotor nozzles (88). The rotor comprises an open-type vessel (42), which in operation is only partially filled with liquid as an annular layer whose radial thickness is determined by outlet passages (721 etc). The rotor is formed from a cap (62), an annular cup-like component (60) with a tubular wall (50) that in use surrounds a spindle and defines an inlet region (66) for pressurized liquid, and a drive member (84) having nozzles (88). The cap and cup-like component are individually molded from synthetic resin and joined to form a vessel (40). Inlet region (66) is connected to the cup by transfer passage (70).

Abstract: A centrifugal separation rotor (130, FIG. 1), for apparatus (110) that removes contaminants from a pumped liquid such as engine lubricant by rotating it about axis (124) at high speed, comprises a separation and containment vessel (132) having impervious side wall (134) spaced from the rotation axis and at least one end wall (138) open at (142) permit liquid to leave the vessel as fast as it can enter, so that a zone (140) is defined adjacent side wall (134) that holds a volume of liquid much less than the whole volume encompassed by the vessel walls and filled in conventional high speed separators. Lower inertia and reduced pressure gradients in the liquid permits it to be spaced further from the axis than is conventional, with improved separation efficiency.

Abstract: A rotor (10) for a centrifugal separator (12) for circulated engine lubricant formed by end walls (44, 46) and radially outer and inner side walls (42, 52) that define a separation and containment region (82). Wall (52) is defined by a tubular tension member (50) that surrounds a rotation axis (30) and extends between and through the end walls to keep them in position. Mounted within first and second ends (72, 74) of the tubular tension member are respective first and second end closure plugs (86, 88). Plug (88) has a passage (90) to admit liquid into the tubular member, but otherwise each plug is seated to inhibit passage of liquid from the member end. Each plug comprises a body seated by interference fit and an integral axially extending component (86?, 88?) that forms a mounting pin for mounting the rotor within bearing parts (24, 28) of the housing.
