De préférence le moteur utilise comme liquide aisément vaporisable du "forane 113" détendu à une pression d'environ 2 bars pour actionner le piston moteur. Selon une autre forme d'exécution de l'invention, le condenseur est refroidi par de Teau pompée par le piston de commande hydraulique et retourne le fréon condensé par une canalisation dans une chemise de longueur adaptée au volume de fréon à réinjecter par le piston de réinjection et le volume de fréon liquide à réinjecter est choisi égal à environ 1/100 de la cylindrée du moteur.Preferably the engine uses as easily vaporizable liquid "forane 113" expanded at a pressure of about 2 bars to actuate the engine piston. According to another embodiment of the invention, the condenser is cooled by water pumped by the hydraulic control piston and returns the condensed freon by a pipe in a jacket of length adapted to the volume of freon to be reinjected by the piston of reinjection and the volume of liquid freon to be reinjected is chosen to be approximately 1/100 of the engine displacement.

D'autres buts et avantages de la présente invention apparaitront à la lecture de la description suivante et des figures données à titre d'exemple, dans lesquelles :Other objects and advantages of the present invention will appear on reading the following description and the figures given by way of example, in which:
- la figure 1 représente une vue en coupe du moteur, les pistons étant au point mort haut, - la figure 2 représente une vue schématique d'une installation de pompage utilisant le moteur selon l'invention, Dans la machine selon l'invention le gaz aisément condensable ou vaporisable tel que du fréon est introduit après vaporisation dans un évaporateur la par l'intermédiaire d'un capteur solaire lb à l'entrée 1 d'un distributeur 2 dont la conduite de sortie 3 est reliée à un cylin¬ dre moteur 5a dans lequel se déplace un piston 5 animé d'un mouvement alternatif à l'intérieur du cylindre 5a.- Figure 1 shows a sectional view of the engine, the pistons being in top dead center, - Figure 2 shows a schematic view of a pumping installation using the engine according to the invention, In the machine according to the invention the easily condensable or vaporizable gas such as freon is introduced after vaporization in an evaporator la by means of a solar collector lb at the inlet 1 of a distributor 2 whose outlet pipe 3 is connected to a cylin¬ dre motor 5a in which a piston 5 moves reciprocating inside the cylinder 5a.
Selon l'invention, le piston 5 es.t relié par un axe 6 à déplacement axial avec un piston'de commande hydrau que 8 mobile dans un cylindre de pompe 8a et constituant le piston de refoulement d'une pompe destinée à absorber l'énergie fournie par le moteur. L'axe 6 est également solidaire à une extrémi é,d'un piston 12 de réinjection du fréon liquide dans son circuit d'évaporation,et à l'autre extrémité,d'un piston distributeur de vapeur 2a qui est rappelle vers la position de départ du cycle moteur par un ressort de rappel 4.According to the invention the piston 5 es.t connected by a shaft 6 axially movable with a piston 'control hydrau 8 movable in a pump cylinder 8a and constituting the delivery piston of a pump for absorbing the energy supplied by the motor. The axis 6 is also integral at one end with a piston 12 for reinjecting the liquid freon into its evaporation circuit, and at the other end with a vapor distributor piston 2a which is returned to the position start of the engine cycle by a return spring 4.
Le moteur, objet de l'invention, est alimenté à l'entrée 1, depuis Tëvaporateur la chauffé par le capteur solaire lb, par du "Forane 113" gazeux à la pression d'environ 2 bars, et vaporisé par Tintermédaire d'un échangeur de chaleur. Le circuit de sortie hydraulique 14 du cylindre de oo pe 8a est raccordé- à une pompe hydraulique 14a placée dans le puit ou le forage. La vapeur provenant de Tëvaporateur la traverse le distributeur 2 ouvert et par la conduite de sortie 3 agit sur le piston 5 lorsqu'il est en position de point mort haut et le repousse vers le bas de la figure. La descente du piston 5 provoque un transfert de Teau du circuit de commande par la canalisation du circuit 14 dans la pompe hydraulique 14a qui refoule vers la surface un volume d'eau égal à sa capacité par une canalisation 15.The motor, object of the invention, is supplied at input 1, from the evaporator heated by the solar collector lb, by gaseous "Forane 113" at the pressure of approximately 2 bars, and vaporized by means of a heat exchanger. The hydraulic outlet circuit 14 of the oo pe cylinder 8a is connected to a hydraulic pump 14a placed in the well or the borehole. The vapor coming from the evaporator crosses it with the distributor 2 open and through the outlet pipe 3 acts on the piston 5 when it is in the top dead center position and pushes it downwards in the figure. The descent of the piston 5 causes a transfer of water from the control circuit by the line of the circuit 14 into the hydraulic pump 14a which delivers towards the surface a volume of water equal to its capacity by a line 15.
En fin de course vers le bas , le piston de réinjection 12 refoule un volume de fréon liquide dans un cylindre ou une chemise 16, vers Tëvapora teur la par la canalisation 17 vi"a un rëchauffeur 10a traversé par le fréon détendu vers le condenseur 10. En fin de course vers le bas, le distributeur 2 ferme l'alimen¬ tation en gaz du moteur, et relie le dessus du cylindre 5 au conden¬ seur 10 par la canalisation 7. Les pressions s'équilibrent et Taxe 6 est rappelle vers le haut de la figure par le ressort de rappel 4. 5 Le piston 8 remonte et la pompe hydraulique revient à sa position d'équilibre en aspirant Teau du circuit de commande 14.At the end of the downward stroke, the re-injection piston 12 delivers a volume of liquid freon into a cylinder or a jacket 16, towards the evaporator there via the line 17 vi " to a reheater 10a crossed by the expanded freon towards the condenser 10 . At the end of the downward stroke, the distributor 2 closes the gas supply to the engine, and connects the top of the cylinder 5 to the condenser 10 by the pipe 7. The pressures balance and Tax 6 is recalled towards the top of the figure by the return spring 4. 5 The piston 8 goes back up and the hydraulic pump returns to its equilibrium position by sucking the water from the control circuit 14.
En fin de course de retour vers le haut, le tiroir du distribu¬ teur 2 se referme et le' "fréon" gazeux est passé complètement dans le condenseur 10 refroidi par Teau de pompage arrivant par la canalisation 10 15. ' At the end of return stroke upwards, the drawer of distribu¬ tor 2 closes and the "Freon" past is completely gas in the condenser 10 cooled by pumping cake arriving via line 15. 10 '
Le fréon liquide condensé retourne dans le cylindre 16 par la canalisation 13 pour être réinjecté au prochain cycle.The condensed liquid freon returns to the cylinder 16 via the line 13 to be reinjected in the next cycle.
La chemise .16 présente une longueur adaptée au volume de fréon à réinjecter par le piston de réinjection 12 et de préférence le volume 15 de fréon liquide à réinjecter est choisi égal à environ 1/100 de la cylindrée du moteur.The jacket .16 has a length adapted to the volume of freon to be reinjected by the reinjection piston 12 and preferably the volume 15 of liquid freon to be reinjected is chosen to be equal to approximately 1/100 of the engine displacement.
Le diamètre du piston de commande 8 et sa course d'actionnement sont déterminés en fonction du volume d'eau à refouler par coup de piston et de la pression nécessaires à la pompe à commande hydraulique 8a. 20 Le diamètre du piston moteur 5 est déterminé en fonction de la pres¬ sion du "fréon" gazeux provenant du capteur solaire via Tëvaporateur la, du diamètre du piston de commande 8 et de la pression à exercer par celui- ci pour actionner la pompe hydraulique.The diameter of the control piston 8 and its actuating stroke are determined as a function of the volume of water to be pumped out by a stroke of the piston and of the pressure necessary for the hydraulically controlled pump 8a. 20 The diameter of the driving piston 5 is determined as a function of the pressure of the gaseous "freon" coming from the solar collector via the evaporator la, the diameter of the control piston 8 and the pressure to be exerted by the latter to actuate the pump. hydraulic.
Le diamètre du piston de réinjection 12 et la longueur de la chemise 25 16 sont déterminés en fonction du volume de "fréon" liquide à réinjecter soit comme indiqué précédemment environ 1/100 de la cylindrée du moteur.The diameter of the re-injection piston 12 and the length of the jacket 25 16 are determined as a function of the volume of liquid "freon" to be re-injected, ie as previously indicated approximately 1/100 of the engine displacement.
Le cylindre de pompe 8a comporte un orifice d'amorçage 18 et un e'vent 9 qui permet de décompresser le dessus du piston 8.The pump cylinder 8a has a priming orifice 18 and a vent 9 which makes it possible to decompress the top of the piston 8.
Le moteur selon l'invention est appliqué de préférence au pompage 30 de Teau, notamment à des profondeurs supérieures à la profondeur d'as¬ piration de Teau par dépression. La pompe de refoulement constituée par le piston de commande hydraulique 8.alimente en eau sous pression le cir¬ cuit de commande 14 raccordé à au moins une pompe hydraulique 14a placée à distance notamment dans un puits 15a, et qui refoule un volume d'eau 35 égal à sa capacité. Le circuit de commande 14 peut être raccordé simultané¬ ment àβ plusieurs pompes hydrauliques séparées telles que la pompe 14a.The motor according to the invention is preferably applied to the pumping 30 of water, in particular at depths greater than the depth of suction of water by vacuum. The delivery pump constituted by the hydraulic control piston 8. supplies pressurized water to the control circuit 14 connected to at least one hydraulic pump 14a placed at a distance in particular in a well 15a, and which delivers a volume of water 35 equal to its capacity. The control circuit 14 can be connected simultaneously to β several separate hydraulic pumps such as the pump 14a.
L'eau pompée dans un puits étant toujours relativement froide même dans les pays chauds, Teau refoulée par au moins une pompe hydraulique placée à distance est amenée par la conduite 15 pour refroidir le condenseur 10 du moteur avant d'être déchargée vers une utilisation par une conduite de décharge 11. L'installation d'ensembles selon l'invention et tels que décrits, trouve son application dans les pays où Teau est rare et Tensoleille¬ ment important. Suivant la profondeur du forage, le débit d'eau qu'il est possible d'obtenir avec les installations en cours de réalisation varie de 500 à 1 500 litres/heure. Bien entendu, la présente invention n'est pas limitée aux modes de réalisation décrits et représentés; elle est susceptible de nombreuses variantes accessibles à l'homme de Tart sans que Ton ne s'écarte pour cela de T-asprit de l'invention. Ainsi Ton doit comprendre que la chemise 16 est disposée à -l'intérieur d'une enceinte 16a reliée par la canalisation 13 au condenseur 10, cette enceinte 16a pouvant elle-même être refroidie par Teau froide pompée. La chemise 16 ne recouvre que la partie finale de la course vers le bas du piston de réinjection 12 de telle manière qu'il est possible de suppri¬ mer le clapet d'aspiration de la pompe de réinjection, le remplissage de l'espace intérieur à la chemise 16 s'effectuant par déversement du fréon liquide 16b accumulé à l'intérieur de Tenceinte 16a sous la pression de vapeur saturée régnant à l'intérieur de Tenceinte 16a. La mise en pression de Tenceinte intérieure à la chemise 16 s'effectue par l'entrée du piston 12 à l'intérieur de cette chemise 16 en fin de course basse de l'équipage constitué par les pistons 5, 8 et 12 attelés ensemble par Taxe 6. Un clapet anti-retour non représenté et installé par exemple sur la canalisation 17 permet d'interdire le retour dans la chemise 16 du fréon refoulé par la pompe de réinjection. On peut aisément ajuster le débit de rëinjection de fréon liquide en changeant les diamètres et/ou les longueurs du piston 12 et de la chemise 16. La pompe de rëinjection constituée par le piston 12 et la chemise 16 peut être remplacée par une pompe à clapets de type connu comme représenté sur la figure 2. The water pumped from a well is always relatively cold even in hot countries, the water pumped by at least one remote hydraulic pump is brought through line 15 to cool the condenser 10 of the engine before being discharged to use by a discharge line 11. Installation of assemblies according to the invention and as described, finds its application in countries where water is scarce and very high sunshine. Depending on the depth of the drilling, the water flow that can be obtained with the installations in progress varies from 500 to 1,500 liters / hour. Of course, the present invention is not limited to the embodiments described and shown; it is susceptible of numerous variants accessible to those skilled in the art without for that reason departing from the spirit of the invention. Thus, it must be understood that the jacket 16 is disposed inside a chamber 16a connected by the pipe 13 to the condenser 10, this chamber 16a being able to be cooled by cold pumped water itself. The jacket 16 covers only the final part of the downward stroke of the re-injection piston 12 in such a way that it is possible to suppri¬ mer the suction valve of the re-injection pump, filling the interior space the jacket 16 is effected by pouring the liquid freon 16b accumulated inside the enclosure 16a under the saturated vapor pressure prevailing inside the enclosure 16a. The pressure inside the jacket 16 is pressurized by the entry of the piston 12 inside this jacket 16 at the end of the low stroke of the crew formed by the pistons 5, 8 and 12 coupled together by Tax 6. A non-return valve not shown and installed for example on the pipe 17 makes it possible to prohibit the return in the jacket 16 of the freon discharged by the reinjection pump. The rejection rate of liquid freon can easily be adjusted by changing the diameters and / or the lengths of the piston 12 and of the jacket 16. The re-injection pump constituted by the piston 12 and the jacket 16 can be replaced by a valve pump. of known type as shown in FIG. 2.
