Abstract
Description
L'objet de l'invention concerne la réalisation d'une pompe manuelle rotative. The object of the invention relates to the production of a rotary manual pump.
Actuellement, les pompes manuelles les plus courantes sont à fonctionnement semi-alternatif, et sont par leur conception assez complexes de rdalisation et plus difficiles d'emploi que la pompe rotative qui fait l'objet du prdsent brevet. Currently, the most common manual pumps are semi-reciprocating, and are by design quite complex to realize and more difficult to use than the rotary pump which is the subject of this patent.
Ce dispositif est remarquable en ce qu'il comporte un rotor excentré muni d'un axe sur lequel viendra s'adapter une manivelle. Ce rotor entraîne deux palettes qui ont pour but de comprimer le liquide pour le refouler vers l'ext- rieur, ce qui provoque un sffet d'aspiration du liquide à pomper, derrière celle-ci. This device is remarkable in that it comprises an eccentric rotor provided with an axis on which a crank will be fitted. This rotor drives two pallets which have the purpose of compressing the liquid in order to discharge it towards the outside, which causes a suction effect of the liquid to be pumped behind it.
La réalisation de cette pompe manuelle, de par sa conception, est de beaucoup simplifier, par rapport aux pompes manuelles existantes, et ne prdsente que très peu de parties pouvant présenter une usure prdmaturde, en comparaison des pièces comme clapets, sièges, roulements, etc... que l'on retrouve sur la plupart des pompes manuelles existantes. The realization of this manual pump, by its design, is to simplify much, compared to the existing manual pumps, and presents only very few parts which can present premature wear, in comparison with parts like valves, seats, bearings, etc. ... found on most existing hand pumps.
Une forme d'exdoution de l'invention est décrite ci-après, à titre indicatif et nullement limitatif, en se référant aux dessins annexes. A form of exclusion from the invention is described below, by way of indication and in no way limitative, with reference to the accompanying drawings.
La figure I est une vue de dessus de la pompe couvercle enlevez
La figure 2 est une vue de côté suivant la coupe I.Figure I is a top view of the cover pump remove
Figure 2 is a side view along section I.
Le dispositif est constitué d'un corps de pompe cylindrique I dans lequel est prévu un trou d'aspiration 10, un trou de refoulement II et un trou d'amorçage I2 avec son bouchon 4. The device consists of a cylindrical pump body I in which is provided a suction hole 10, a delivery hole II and a priming hole I2 with its plug 4.
Ce corps de pompe I servira dgalement à recevoir un couvercle 2 dont l'axe central I3 est destins maintenir les deux palettes 8 et 9 à l'intérieur et au centre du corps de pompe I. This pump body I will also serve to receive a cover 2 whose central axis I3 is intended to maintain the two vanes 8 and 9 inside and in the center of the pump body I.
La fixation du couvercle 2 sur le corps de pompe I se fait par six vis à tête hexagonales I4, un joint 3 venant s'intercaler entre les deux parties assurera ltétanchéité de la pompe. The fixing of the cover 2 on the pump body I is done by six hexagonal head screws I4, a gasket 3 coming between the two parts will ensure the tightness of the pump.
Le mdcanisme contenu dans le corps de pompe I est cons titubé
a) d'un rotor 7, dont l'axe servira à recevoir la mani velle et éventuellement un petit volant d'entrainement facilitant la rotation. Ce rotor 7, sur lequel sont prévues deux rainures, est destiné à entratner par sa rotation, les deux palettes 8 et 9. L'axe de ce rotor se trouve excentré dans le corps de pompe I pour permettre la circulation du liquide à pomper. Une cage 5 renfermant un joint simrit 6 assurera une étanchéité du côté de cet axe de rotor 7.The mechanism contained in the pump body I is built up
a) a rotor 7, the axis of which will be used to receive the crank and possibly a small drive wheel facilitating rotation. This rotor 7, on which two grooves are provided, is intended to drive, by its rotation, the two vanes 8 and 9. The axis of this rotor is eccentric in the pump body I to allow the circulation of the liquid to be pumped. A cage 5 containing a simrit seal 6 will ensure a seal on the side of this rotor axis 7.
b) de deux palettes 8 et 9 centrées dans le corps de pompe I par l'intermédiaire de l'axe 13 du couvercle 2. Ces deux palettes 8 et 9 venant se loger dans les rainures prd- vues sur le rotor 7 seront entratndes dès la rotation de ce dernier. b) two vanes 8 and 9 centered in the pump body I via the axis 13 of the cover 2. These two vanes 8 and 9 which are housed in the grooves provided on the rotor 7 will be driven as soon as the rotation of the latter.
Ces palettes ont pour but de refouler le liquide contenu à l'intérieur de la pompe vers l'extérieur en le compressant vers l'orifice de refoulement II dont le diamètre sera inférieur à l'orifice d'aspiration 10. En même temps que la compression créée par la poussée des palettes 8 et 9, il se produit der rière celle-ci un effet d'aspiration du liquide à l'intdrieur de la pompe. Pendant que la première palette 8 compresse et aspire le liquide, la seconde palette 9 empêche ce même liquide de redescendre par le conduit d'aspiration IO. The purpose of these vanes is to discharge the liquid contained inside the pump towards the outside by compressing it towards the delivery orifice II whose diameter will be less than the suction orifice 10. At the same time as the compression created by the push of the vanes 8 and 9, there is behind the latter a suction effect of the liquid inside the pump. While the first pallet 8 compresses and sucks the liquid, the second pallet 9 prevents this same liquid from going back down through the suction pipe IO.
Les deux palettes 8 et 9 servent donc tour à tour à aspirer le liquide et à le refouler, puis de retenue pour main te- nir le liquide à l'intérieur de la pompe. The two vanes 8 and 9 therefore serve in turn to suck up the liquid and to discharge it, then to retain it to keep the liquid inside the pump.
A la première utilisation, il faudra veiller à l'amorçage de la pompe. When using for the first time, care must be taken to prime the pump.
Cette pompe rotative manuelle pourra être réalisée entièrement en matière plastique ou nylon, ne ndeessitant que très peu d'usinage, d'où un prix de revient relativement peu élevé par rapport aux pompes manuelles existantes. De par sa conception et sa réalisation, cette pompe ne nécessite aucun entretien particulier, et ne peut présenter aucun problème de non fonctionnement. This manual rotary pump can be made entirely of plastic or nylon, requiring only very little machining, hence a relatively low cost price compared to existing manual pumps. By design and construction, this pump does not require any particular maintenance, and cannot present any problem of non-operation.
I1 est bien entendu que la présente invention n'est pas limite au mode de réalisation décrit et représenté qui constitue seulement un exemple auquel de nombreuses modifications peuventêtre apportées sas qu'on s'écarte de la prdsente in Invention. I1 is understood that the present invention is not limited to the embodiment described and shown which is only an example to which many modifications can be made without departing from the present invention.
