The lower base of the container body incorporates a check valve for the intake of water. The bottom of the third, vertical tube includes a check valve with a vertically movable obturator, extended at the bottom by means of an axial rod. The obturator is connected, by means of a flexible element, to a weight floating on the surface of the water inside. The pump functions continuously with no energy to actuate it other than that of the pressurized air entering its top part.

DESCRIPCIÓN DETALLADA DE LA INVENCIÓNDETAILED DESCRIPTION OF THE INVENTION
Los elementos designados con números en los dibujos corresponden a las partes indicadas a continuación.The elements designated with numbers in the drawings correspond to the parts indicated below.
La bomba elevadora de agua objeto de esta patente de invención comprende un cuerpo contenedor 1 de forma, por ejemplo, cilindrica de eje vertical, de paredes metálicas y resistentes a la corrosión, apta para su inmersión en una masa 2 de agua. Conviene asegurar la existencia continuada de una capa superior 3 de agua por encima del cuerpo 1.The water lift pump object of this patent of invention comprises a container body 1 of, for example, cylindrical vertical axis, metal walls and corrosion resistant, suitable for immersion in a body of water 2. It is important to ensure the continued existence of a top layer 3 of water above the body 1.
El conducto vertical 4 constituye la entrada del aire a presión en el cuerpo 1 y su extremo 5 desemboca en la parte superior de dicho cuerpo.The vertical duct 4 constitutes the entrance of the pressurized air into the body 1 and its end 5 flows into the upper part of said body.
El conducto vertical 6 constituye la salida del agua impulsada ascendente, comporta en su parte media una válvula 7 de no retorno y su extremo inferior 8 queda próximo al fondo 9 del cuerpo 1. El citado fondo 9 comprende una válvula de pié y no retorno (retención) 10 para la admisión de agua en el cuerpo 1, impidiendo la salida indeseada de la misma.The vertical duct 6 constitutes the outlet of the upwardly driven water, in its middle part comprises a non-return valve 7 and its lower end 8 is close to the bottom 9 of the body 1. Said bottom 9 comprises a foot and non-return (check) valve 10 for the admission of water in the body 1, preventing the unwanted exit thereof.
El conducto vertical 11, inserto en la base superior del cuerpo 1, sirve para la salida de aire de ventilación, y lleva asociada una válvula 12 de no retorno, cuyo elemento obturador, móvil en dirección vertical, puede adoptar dos posiciones limites: superior (válvula cerrada) e inferior (válvula abierta), según las mencionadas figuras 3 y 4.The vertical duct 11, inserted in the upper base of the body 1, serves for the ventilation air outlet, and is associated with a non-return valve 12, whose sealing element, movable in the vertical direction, can adopt two limit positions: upper ( valve closed) and bottom (valve open), according to the mentioned figures 3 and 4.
El obturador se prolonga axialmente en un vastago 13 en su parte inferior, y se une mediante un hilo o cadenilla 14 a una masa 15 de peso calculado.The plug extends axially in a rod 13 in its lower part, and is connected by a thread or chain 14 to a mass 15 of calculated weight.
La masa 15 es de forma, volumen y material adecuados para flotar sobre el agua y, en su momento, tirar hacia abajo el obturador de la válvula 12.The mass 15 is of suitable shape, volume and material to float on the water and, in turn, pull the valve plug 12 down.
El obturador tiene la forma representada en las figuras 3 y 4, su cabeza 13a es de forma cónica, conjugada de la embocadura inferior del conducto 11. Una junta tórica 17 asegura el cierre de la válvula 12 en la posición de la figura 3.The shutter has the shape shown in Figures 3 and 4, its head 13a is conical, conjugated to the lower opening of the duct 11. An O-ring 17 ensures the closure of the valve 12 in the position of Figure 3.
Unos orificios laterales 18 en la parte inferior de la válvula 12 permiten la admisión continuada (según las flechas horizontales) del aire interior del cuerpo 1 de la bomba. Cuando la válvula se halla abierta, según la figura 4, dicho aire debe escapar al exterior (según las flechas verticales y ascendentes de la parte superior) .Lateral holes 18 in the lower part of the valve 12 allow the continuous admission (according to the horizontal arrows) of the internal air of the pump body 1. When the valve is open, according to figure 4, said air must escape to the outside (according to the vertical and ascending arrows at the top).
El funcionamiento de la bomba descrita es como sigue:The operation of the pump described is as follows:
En la fase de la figura 1, con el cuerpo 1 lleno de agua, la válvula de pié 10 está cerrada, el aire comprimido entrante por el conducto 4 (ver flechas) ejerce presión sobre el agua interior y obliga a ésta a ascender por el conducto 6 de salida (ver flecha) . La válvula 16 de la entrada impide el retroceso del aire entrante y la válvula 7 de la salida evita el retroceso del agua ascendente.In the phase of figure 1, with the body 1 filled with water, the foot valve 10 is closed, the compressed air incoming through conduit 4 (see arrows) exerts pressure on the internal water and forces it to ascend through the outlet conduit 6 (see arrow). The inlet valve 16 prevents the return of the incoming air and the outlet valve 7 prevents the withdrawal of the rising water.
La válvula 12 está cerrada, en la posición superior del obturador (figura 3), por el empuje ascendente que realiza contra el obturador la masa flotante 15, que descansa sobre el nivel del agua interior del cuerpo 1 y cuya cara superior se aplica contra el extremo del vastago 13 derivado del obturador. El hilo flexible o cadenilla 14 se halla destensado e inoperante.The valve 12 is closed, in the upper position of the shutter (Figure 3), by the upward thrust that the floating mass 15 makes against the shutter, which rests on the level of the interior water of the body 1 and whose upper face is applied against the rod end 13 derived from the plug. The flexible thread or chain 14 is loosened and inoperative.
En la fase de la figura 2, el nivel del agua interior inicialmente es bajo, la masa 15 queda suspendida, gracias a su peso, por el hilo o cadenilla 14 (ahora tensado) , y la válvula 12 está abierta (figura 4); asi, el aire interior del cuerpo 1 tiene salida al exterior (flechas) por el conducto 11.In the phase of figure 2, the level of the interior water is initially low, the mass 15 is suspended, thanks to its weight, by the thread or chain 14 (now tensioned), and the valve 12 is open (figure 4); thus, the interior air of the body 1 has an outlet to the outside (arrows) through the conduit 11.
La válvula de pié (retención) 10 permite la entrada de agua e impide su salida. El aumento de nivel del agua en el interior del cuerpo 1 provocará seguidamente la elevación de la masa flotante 15 y el cierre de la válvula 12, según la figura 3, repitiéndose el ciclo.Foot valve (check) 10 allows water to enter and prevents its exit. The increase in water level inside the body 1 will then cause the floating mass 15 to rise and the closure of the valve 12, according to figure 3, the cycle being repeated.
El funcionamiento de la nueva bomba es continuo y se produce sin más aportación de energía que la entrada de aire a presión por el conducto 4.The operation of the new pump is continuous and occurs without more energy input than the entry of pressurized air through the conduit 4.
Las dos fases indicadas a continuación resumen el funcionamiento de la nueva bomba:The two phases indicated below summarize the operation of the new pump:
Fase Ia. Colocación de la bomba en un pozo y cubrimiento de agua, llenándose el interior del cuerpo 1. Entrada de aire comprimido por el conducto 4, mantenimiento de la válvula 12 y desalojo del agua interior del cuerpo 1, obligándola a ascender por el conducto vertical 6.Phase I a . Placing the pump in a well and covering of water, filling the interior of the body 1. Compressed air inlet through the conduit 4, maintenance of the valve 12 and evacuation of the internal water from the body 1, forcing it to ascend through the vertical conduit 6.
Fase 2a. Representada en la figura 2, comprende las acciones siguientes:Phase 2 a . Represented in Figure 2, it includes the following actions:
