Abstract

The invention relates to a compressor (2) which is encapsulated in a housing (4) and which can be rotated about the axis (16) of its crankshaft (8) while maintaining the oil lubrication of the moving parts of the compressor. The interior (14) of the housing (4), in which an oil sump (18) is located, is connected flow-wise to the compressor (2). According to the invention, the interior (14) is connected to two gas lines (24, 26) which lead to a common manifold (32) via at least one shutoff valve (28, 30). The connecting openings (25, 27) of the two gas lines (24, 26) leading into the interior (14) are arranged opposite to one another in the vicinity of the axis (16) of the crankshaft (8). By these measures, the compressor can be inclined relative to the horizontal over a wide angular range without lubricating oil flow into the gas loop.
