Abstract
To improve a compressor for refrigerant, comprising an outer casing, a scroll compressor disposed in the outer casing, a drive unit, disposed in the outer casing, for the second compressor body, having an eccentric drive, a drive shaft running in lying arrangement or approximately horizontally in the outer casing and a drive motor, which includes a stator and a rotor seated on the drive shaft, as well as a lubricant supply, in such a manner that the minimum possible quantity of lubricant is required, it is proposed that a lubricant collection space is disposed in the outer casing, that the lubricant supply has a delivery wheel which delivers lubricant from a delivery sump into a feed space for the drive shaft, and that a lower pressure prevails in a lubricant delivery space accommodating the delivery sump than in the lubricant collection space, so that the lubricant which collects in the lubricant space, on account of the pressure difference, passes into the delivery sump.
