Abstract
1380760 Rotary positive-displacement machines AGINFOR AG FUR INDUSTRIELLE FORSCHUNG 11 Dec 1972 [10 Dec 1971] 56980/72 Heading F1F A rotary positive-displacement machine comprises a displacement chamber divided into two sections 10, 11 each section having a partcylindrical ring-shape and being defined by an inner convex surface 23, 24, an outer concave surface 22, 25 and axial end plane closure surfaces. The sections are joined by a passage 15 and section 10 has inlet 13 and section 11 has outlet 18. A displacement device comprises two rigidly interconnected vanes 20, 21 of part-cylindrical ring- shape, the device being rotable in a circle so as to move the vanes in a circular motion in direction 33. The vanes and chamber sections each extend over 270 degrees and are displaced in orientation with respect to each other by 90 degrees. In Fig. 1 vane 20 is shown as contacting the inner and outer walls 23, 22 at points 29, 30 respectively whilst vane 21 touches only the outer wall 25 at point 31. Thus there is flow communication between passage 15 and outlet 18 whilst vane 20 blocks off inlet 13 from passage 15 and acts alone as a pumping or driving member. Fig. 2 shows the situation after movement in direction 33 of the displacement member through 45 degrees. Here the vane 20 contacts only the inner surface 23 at point 29, thus permitting through flow from inlet 13 to passage 15, but communication between passage 15 and outlet 18 is cut off by vane 21 which engages both walls 24, 25 at points 32, 31 and thus acts as the pumping or driving member. Other embodiments employ three vanes and three chambers Figs. 3 and 4 (not shown), two pairs of vanes and chambers arranged in parallel, each pair being of the type shown in Figs. 1 and 2, Fig. 5 (not shown), two vanes in each chamber Fig. 6, (not shown), and a machine of the type in Figs. 1 and 2 but with the chambers arranged axially in a stacked construction Fig. 7, (not shown).
