  • Patent number: 10337773
    Abstract: A cooling system includes a refrigerant compressor and a first operating medium, which provides a mixture of refrigerant and lubrication oil. An oil separator reduces the percentage of the refrigerant in the operating medium to a value between 15% by weight and 50% by weight.
    Type: Grant
    Filed: November 9, 2016
    Date of Patent: July 2, 2019

  • Patent number: 10295232
    Abstract: A cooling system includes a refrigerant compressor and a first operating medium, which includes a mixture of refrigerant and lubrication oil. An oil separator reduces the percentage of the refrigerant in the operating medium so that a second lubrication oil enriched operating medium is provided by the oil separator, the provided second operating medium having at least in a second operating state a viscosity ratio of ?>1.

  • Patent number: 9670959
    Abstract: A bearing comprising a plurality of rolling elements arranged between an inner and outer raceway thereof. A rolling contact interface is between a first rolling contact surface on at least one rolling element and a second rolling contact surface formed by one of the inner and outer raceways. The first rolling contact surface has a first RMS roughness Rq1 and a first roughness pattern ?1, expressed in terms of the Peklenik number ?. The second rolling contact surface has a second RMS roughness Rq2 and a second roughness pattern ?2. To minimize micropitting in the bearing, the rolling contact interface has a surface topography wherein (a) the roughness pattern of the first and second rolling contact surfaces are oriented in the direction of rolling, whereby ?1?3.0 and ?2?10.0; and (b) the first and of the second rolling contact surfaces have substantially equal roughness heights, whereby 0.8?Rq1/Rq2?1.25.
