925,490. Rotary compressors. BECKER G.m.b.H. GEB. May 10, 1961 [May 24, 1960], No. 17076/61. Class 110 (2). A rotary sliding vane compressor has a settling chamber 32 formed in its base, downstream of which is a cooler 34 and an oil separator (Fig. 3, not shown). The compressor is lubricated by oil forced into the working chamber and the bearings from an oil tank 19 by a pump 18. 50% of the oil in the delivery air is removed in the settling chamber 32, and flows back to the oil tank 19 under delivery pressure. The cooler 34 consists of cooling chambers 35 connected in series to form a continuous passage, and downstream of this is provided the oil separator comprising a ceramic filter (Fig. 3, not shown) which removes a further 45% of the oil. The compressor, which is driven by a motor 16 through a clutch 15, is provided with a fan 17 which blows cooling air over the cooler, which may alternatively be arranged as an annulus around the fan, and through cooling passages 14 around the working chamber. A small auxiliary air intake is provided, from which air passes, through opening 28, into the working chamber near the point of maximum suction. The intake housing contains a paper filter element and has a space 40 for the storage of spare filter elements. The intake filter and oil filter are accessibly mounted adjacent one another. |
