Patent number: 8695159Abstract: A vacuum cleaner (1, 21, 31) comprises an air inlet opening (3), an air outlet opening (6) and a rotatable separator (9) for separating air and airborne particles. The separator (9) comprises at least one air entrance opening (109) located between the air inlet opening (3) and the air outlet opening (6). The vacuum cleaner (1, 21, 31) is provided with air-guide means (15, 22, 37) for guiding at least part of the air towards the separator (9). In use, the air-guide means (15, 22, 37) provides an at least partially closed boundary in axial direction for a column of rotating air (17) around the separator (9). The minimum distance (Rag) of an edge (115, 122) of the air-guide means (15, 22, 37) to the rotating axis (11) of the separator (9) is larger than a distance (Rs) of the air entrance opening (109) of the separator (9) to the rotating axis (11) of the separator (9).Type: GrantFiled: December 3, 2010Date of Patent: April 15, 2014Assignee: Koninklijke Philips N.V.Inventors: Johannes Tseard Van Der Kooi, Fokke Roelof Voorhorst, Bastiann Johannes De Wit, Joldert Maria Boersma

Patent number: 8679214Abstract: The present invention relates to a separator and more specifically, but not exclusively, to a centrifugal separator for the cleaning of a gaseous fluid. A centrifugal separator is provided as comprising a housing defining an inner space, and a rotor assembly for imparting a rotary motion onto a mixture of substances to be separated. The rotor assembly is located in said inner space and is rotatable about an axis relative to the housing. The rotor assembly comprises an inlet for receiving said mixture of substances, an outlet from which said substances are ejected from the rotor assembly during use, and a flow path for providing fluid communication between the inlet and outlet, wherein the outlet is positioned more radially outward from said axis than the inlet.Type: GrantFiled: January 10, 2012Date of Patent: March 25, 2014Assignee: Alfa Laval Corporate ABInventor: Mats-Orjan Pogén

Patent number: 8673063Abstract: A particulate loader separation device including a particulate and air inlet for receiving a flow of air and particulate. A separation chamber for separating the air and the particulate is connected to the particulate and air inlet. An air outlet is connected to a suction mechanism for providing suction to the separation chamber. A particulate outlet is connected to a particulate conveyor for conveying the particulate from the separation chamber. An inlet air extractor is connected to the particulate and air inlet and is connected to one of the suction mechanism and a second suction mechanism. The inlet air extractor is connected to the particulate and air inlet at a predetermined location thereof such that in operation a portion of the air of the flow of air and particulate is extracted prior entering the separation chamber.Type: GrantFiled: August 5, 2011Date of Patent: March 18, 2014Assignee: REM Enterprises Inc.Inventor: Paul J.
