发明名称 Device for oil-gas separation in a crankcase
摘要 The gas purification device (10) comprises a separation element (15) rotating around an axis (A) and having a coalescing medium (12) arranged annularly around the axis, an envelope, and a system consisting of two separated parts for rotating the separating element from outside the cavity by a magnetic gear between two magnetic bodies of a first of two parts external to the cavity and two magnetic bodies of a second of two parts arranged inside the cavity and rotating with the separation element. The envelope comprises a first peripheral wall (13) around the separating element. The gas purification device (10) comprises a separation element (15) rotating around an axis (A) and having a coalescing medium (12) arranged annularly around the axis, an envelope, and a system consisting of two separated parts for rotating the separating element from outside the cavity by a magnetic gear between two magnetic bodies of a first of two parts external to the cavity and two magnetic bodies of a second of two parts arranged inside the cavity and rotating with the separation element. The envelope comprises a first peripheral wall (13) around the separating element, and a second wall (18), which extends transversely with respect to the axis (A) and defines a cavity, with the peripheral wall, inside of which the separation element is housed. The separation element defines an upstream zone of untreated gas contacting with a motor housing and a downstream area of treated gas contacting with an outlet. The separating element is removable, and comprises two flanges between which the coalescer medium is fixed. One of the flanges supports or comprises the magnetic organs of the second of two parts. The magnetic bodies of part external to the cavity are distributed around an axis defined by a first rotating shaft. Each of magnetic bodies of the part external to the cavity is magnetically coupled with one of magnetic bodies of the part arranged inside the cavity. The separating element is attached to a hollow second rotating shaft. The first rotating shaft is coaxial with the second rotating shaft, and the coalescer medium extends in a ring around the second rotating shaft. The magnetic bodies of the portion arranged inside the cavity comprise two permanent magnets each having north and south poles aligned perpendicular to the axis (A) of rotation of the separation element. The first wall and/or the second wall are non-magnetic. Independent claims are included for: (1) a separation element to cooperate with the gas purification device; and (2) a process for manufacturing the separation element.
