Abstract
In an axial piston compressor for a refrigerant, in particular for a vehicle air conditioner, with a housing () in the interior of which is disposed at least one bearing (), with an output conduit () for the compressed refrigerant, and with a lubricant that is present in the interior of the housing (), the lubrication is to be improved. For this purpose there is provided in the housing at least one lubricant channel to conduct lubricant to the bearing, as well as a lubricant separator () that is connected to the output conduit () for the refrigerant and incorporates a collection chamber () that contains the lubricant separated from the compressed refrigerant and is connected to the lubricant channel () by a feed line (), such that the lubricant is propelled out of the lubricant separator and into the lubricant channel entirely on the basis of the pressure difference between the compression pressure of the lubricant and the interior pressure of the housing.
