A lubricating system, preferably for smaller refrigerating machinery of piston compressor type (1, 2, 3) having a substantially vertically extending drive shaft (4). A disc-shaped member (11) is arranged adjacent to the lower part of the drive shaft (4) to be rotated by the rotary movement of the drive shaft (4), arranged having oil transferring means (12; 20, 20', 20'') communicating with oil in an underlying oil reservoir (10). Said oil transferring means (12; 20, 20', 20'') will during a rotary movement transfer oil from the oil reservoir (10) to the upper plane of the disc-shaped member (11), and a tubular pipe (14), having its lower open part (15) open against the rotary direction at the peripheral part of the disc-shaped member (11), moves in the manner of a Pitot pipe pump oil via the tubular pipe (14) from the disc-shaped member (11) for lubrication of the piston compressor (1, 2, 3). The lower portion of the drive shaft (4) can be arranged with a downwardly open conically reduced tubular member (9), which at a high rotary speed collects and transfers oil through a channel taken up in the drive shaft (4) for lubrication of the piston compressor. |
