Patent number: 10634137Abstract: A refrigeration system with two or more compressors configured to compress a flow of refrigerant with oil entrained therein. A suction flow piping arrangement is configured to supply a flow of refrigerant and oil to the two or more compressors. The suction flow piping arrangement has a suction header configured to carry the flow of refrigerant and oil, and a primary compressor supply conduit connected to the suction header. The primary compressor supply conduit supplies refrigerant and oil to a first compressor of the two or more compressors. A secondary compressor supply conduit branches off from the suction header. The secondary compressor supply conduit supplies refrigerant to a second compressor of the two or more compressors. The primary compressor supply conduit is configured to supply more oil to the first compressor than the secondary compressor supply conduit supplies to the second compressor.Type: GrantFiled: July 1, 2013Date of Patent: April 28, 2020Assignee: BITZER Kuehlmaschinenbau GmbHInventors: Bruce A. Fraser, Ronald J. Duppert, Wayne P. Beagle

Patent number: 10634138Abstract: A device for measuring flow processes of fluids includes an inlet, an outlet, a housing in which is arranged a drivable positive displacement flow meter which includes a positive displacement chamber in which a driven impeller is rotatably arranged, a first supply duct connecting the displacement chamber with the inlet, a first discharge duct connecting the displacement chamber with the outlet, a first inlet port, a second supply duct connected to the inlet, a displacement flow meter bypass with a differential pressure sensor, and an evaluation and control unit which controls the displacement flow meter based on a differential pressure applied to the pressure sensor. Cavitation wear of the positive displacement meter is reduced by the first supply duct opening into a front of the displacement chamber via the first inlet port, and the second supply duct opening into a rear of the displacement chamber via a second inlet port.Type: GrantFiled: September 15, 2016Date of Patent: April 28, 2020Assignee: AVL LIST GMBHInventors: Otfried Derschmidt, Heribert Kammerstetter

Patent number: 10634139Abstract: A scroll compressor includes a fixed scroll and an orbiting scroll, which are made of materials having different strengths and which include respective scroll laps. The scroll lap of the fixed scroll and the orbiting scroll having a lower material strength has a thickness satisfying tl=2a?, where tl represents scroll lap thickness, a represents basic circle radius, and ? represents phase angle. The scroll lap of the fixed scroll and the orbiting scroll having a higher material strength has a thickness satisfying th=2a?, where th represents scroll lap thickness, a represents basic circle radius, and ? represents phase angle. The scroll lap thickness th of the fixed scroll and the orbiting scroll having the higher material strength is set to be less than the scroll lap thickness tl of the fixed scroll and the orbiting scroll having the lower material strength.Type: GrantFiled: June 10, 2015Date of Patent: April 28, 2020Assignee: Mitsubishi Electric CorporationInventors: Kohei Tatsuwaki, Fumihiko Ishizono, Masayuki Kakuda

Patent number: 10634141Abstract: To be as lightweight and compact, for example for automotive technology, a scroll compressor further includes an axial guide that supports the movable compressor body to prevent movements in the direction parallel to a centre axis of the stationary compressor body and, in the event of movements, guides it in the direction transverse to the centre axis. A coupling prevents the movable compressor body from rotating freely. The axial guide supports a compressor body base, which carries the scroll vane, of the second compressor body against an axial support face, in that the axial support face abuts a sliding body such that it is slidable transversely to the centre axis. The sliding body is slidable transversely to the centre axis, on a carrier element that is arranged in the compressor housing.Type: GrantFiled: March 15, 2017Date of Patent: April 28, 2020Assignee: BITZER Kuehlmaschinenbau GmbHInventors: Dimitri Gossen, Muzaffer Ceylan
