Description

pompe rotative. Lobjet de la präsente invention äst une pompe rotative, comprenant un rotor tournant dann un earter. Cette pompe äst caracteris6e en ce que ce dernier, qui repose sur un reser- voir d'huile de graissage, präsente, pres de 1'endroit oü 1e rotor touche au carter, un eanal, au moins approximativement parallele ä laxe du rotor, relie, par un tube, au fond du reservoir et communiquant par des trous, de petite section, avec 1'int6rieur du carter. rotary pump. The object of the present invention is a rotary pump, comprising a rotor rotating in a sump. This pump is characterized in that the latter, which rests on a reservoir of lubricating oil, has, near the place where the rotor touches the casing, a channel, at least approximately parallel to the axis of the rotor, connects , by a tube, at the bottom of the tank and communicating by holes, of small section, with the interior of the casing.

La dessin ei-annexe represente, ä titre d'exemple, une forme d'execution de 1'objet de la pr6sente invention. The appended drawing represents, by way of example, one form of execution of the object of the present invention.

La fig. 1 en äst une section droite; la fig. 2 äst une coupe horizontale par II-II, et la fig. 3, une coupe verticale par III-III de fig. 1. fig. 1 in äst a straight section; fig. 2 is a horizontal section through II-II, and fig. 3, a vertical section through III-III of fig. 1.

l äst un carter dans lequel peut tourner 1e rotor 2, uruni de palettes 3, mobiles dans des rainures 4. Ce oarter äst fixe sur un r6cipient ä huile de graissage 5. 6 äst 1e conduit d'aspiration et 7 Je conduit de re- foulement; lorsque 1e rotor tourne dans 1e sens de la fleche f, il aspire de Fair du Aservoir, non represente, A 1'on veut faire 1e vide et qui äst relie au conduit 6; cet air äst refou16 dass 1e r6servoir ä huile d'oü il gagne 1'atmosphere par la tubulure 8 et par 1e conduit 7. 9 et 10 sont des chicanes. 1 is a casing in which the rotor 2 can rotate, fitted with vanes 3, movable in grooves 4. This casing is fixed on a lubricating oil container 5. 6 is the suction duct and 7 is the return duct. crowding; when the first rotor rotates in the direction of the arrow f, it sucks from the air of the reservoir, not shown, A 1'one wants to make the vacuum and which is connected to the conduit 6; this air is discharged into the oil tank from where it gains the atmosphere through the pipe 8 and through the duct 7. 9 and 10 are baffles.

Le carter 1 präsente pres de 1'endroit 11, oit il äst en contact avec 1e rotor et sur sa face ext6rieure, un conduit 12 parallele ä faxe du rotor et qui präsente une tubulure 13, dans laquelle p6netre un tube 14 qui descend jusque pres du Fond du reservoir. Ce conduit communique par trois orifices 15, de petite section, avec 1'int6rieur du carter; en outre, las flasques 16 Jans lesquels tournent las tourillons du rotor, pr6sentent deux canaux verticaux 17 reliant las paliers de ces touril- lons avec las deux extremit6s du canal 12. The casing 1 presents near the place 11, where it is in contact with the rotor and on its external face, a duct 12 parallel to the axis of the rotor and which presents a pipe 13, into which a tube 14 penetrates which descends to near from the bottom of the tank. This duct communicates via three orifices 15, of small section, with the interior of the casing; in addition, the flanges 16 Jans which turn the journals of the rotor, present two vertical channels 17 connecting the bearings of these journals with the two ends of the channel 12.

Lorsque 1e rotor tourne Jans 1e sens de la fleche f, il aspire de 1'huile de graissage par 1e tube 14 et las trous 15; en outre, par capillarite, une Partie de cette huile monte dass las paliers des flasques 16 par las conduits 17. L'huile qui West pas em- ploy6e au graissage retourne Jans 1e r6ci- piept 5 oii elle Teste, les chicanes 9 et 10 empechant quelle ne sorte par la tubulure B. When the rotor rotates in the direction of arrow f, it draws in lubricating oil through tube 14 and holes 15; in addition, by capillarity, part of this oil rises in the bearings of the flanges 16 through the conduits 17. The oil which is not used for lubrication returns to the container 5 where it tests, the baffles 9 and 10 preventing it from coming out through tubing B.
