Definitions
- the parts or a rotary engine, especially the rotor, are subjected to a thermal flux and also to heat stresses which make special cooling arrangements necessary.
- a known solution consists of arranging a circulation of a cooling liquid in the interior of the rotor, this circulation being effected by starting from the hottest zones.
- the present applicants have proposed to arrange inside the rotor two conduit systems for the cooling liquid, each of these comprising a radial intake conduit leading the liquid to a peripheral conduit which rst passes round a hot lobe and then a cold lobe, before bringing the said cooling liquid baclt to a radial outgoing conduit.
- the present invention has for its object an improved circuit arrangement for the cooling liquid, for the purpose of reducing the weight and simplifying the assembly of ⁇ the rotor.
- the liquid is brought in from the hub through radial conduits directly to the summits of the hot lobes, from which it passes into chambers located on eac-h side and extending under the cold lobes, but without any lperipheral circulation channel being provided, the liquid returning through passages opening from these chambers into the hub.
- FIG. 1 is a transverse section of a rotor
- FIG. 2 is a cross-section taken along the line lI-II of FIG. 1;
- FIG. 3 is a cross-section along the line III-lll of FIG. 1.
- the rotor 1 comprises four lobes 2, 3, d, 5, two of which, 2 and 4 having opposite summits and intended to function as hot lobes, are provided radially wit-h hollow arms 6, '7, forming passages for the cooling liquid and opening into the hub 8.
- the interior portion ot' the rotor is divided-up by the arms 6 and 7 and the partitions 9 and 10 into our chambers 11, 12, 13 and 14, into which the cooling liquid passes through the extremities of the arms 6 and 7 which communicate respectively with the two adjacent chambers, and from which the said liquid is evacuated through the openings 15, 16, 17 and 18, after 'having passed through the cold lobes, but without any denitely established circulation being produced in this Zone.
- Transverse webs 19, 20, 21 and 22, couple together the sides 23 and 24 of the rotor.
- the cores which serve for casting the hollow portions can be given large central bearing surfaces which enable them to be held easily in position in the mould and further ensures easy cleaning of the cast parts.
