ATTILIO G-IAILEVER, OF S. MARGHERITA LIGURE, ITALY.

EXPLOSION-PUMP.

Specification of Letters Patent.

Patented Nov. 26, 1918.

Application filed April 27, 1915. Serial No. 24,331.

To all whom it may concern:

Be it known that I, ATTILIo GIAILEVER, engineer, subject of the King of Italy, residing at S. Margherita Ligure, Italy, have invented certain new and useful Improvements in Explosion-Pumps, of which the following is a specification.

The present invention relates to a water pumping device of the kind in which the power for the direct pumping of water is obtained by the explosion of any gas, separate chambers being provided for the compression of the gas and the production of an explosion. The subject matter of the application differs from these known devices owing to-the fact that the compression chamber is provided above the level of the liquid to be raised and is connected with the rising pipe of the explosion chamber through the medium of a compound valve controlled by thecolumn of water oscillating to and fro, while for controlling the valve for the compressed gas, for the ignition of the same and for the exhaust valve, a float is provided within the compression chamber.

An arrangement of this kind has the advantage of being very simple and having a safe operation. y

In the accompanying drawings:

Figure 1 is a sectional side elevation of my pump showing the beginning of the explosion stroke.

Fig. 2 discloses the reservoir or chamber Fig. 3 illustrates the position of the various parts of the apparatus, as the same will appear at the completion of the explosion stroke.

Fig. 4: discloses various details in side elevation and section of the explosion apparatus which serves to compress the fluid and force the same to a high level.

Fig. 5 illustrates parts, such as disclosed in Fig. 4:, but in front elevation.

Fig. 6 is a detail view disclosing the structure of the compound valve utilized in con-' nection with this device.

The device consists of an explosion chamber A which is provided with the bottom valves 8 and 9. Between the latter there terminates the rising pipe. C, D opening vinto a receptacle E provided with the outlet pipe h. 4 n

The compression chamber Bis located level, said compression chamber communicating on the one hand, with the rising pipe C and on the other, with the pipe D, and in addition thereto is provided with the outlet pipe 6 leading to the well. At the connecting point of the pipes, a compound valve 5, 6, 7 is provided which is controlled by a single spindle. The movement of the valve 5, 6,7 is effected by the levers u, of mounted on the axis 2', which levers w, u are operated by the manually actuated chain m. The chamber B is connected with the chamber A by the tube 0 provided, it its ends, with the valves 3 and 1, the formerof which is operated by a cam ac keyed on the axis 39 of a float cl located in the chamber B. Upon the ,7

The device operates in the following manner:

In the operative position, the device is plunged into the liquid to the requisite depth. The liquid enters through the valves 8, 9 into the explosion chamber A until it has reached the outer level, air escaping at the same time through the valve 2. The small body of water necessary to start the working of the apparatus is filled into the receptacle E in any desired well known manner until.

the receptacle Evand the compression chamber B and the pipe D are full and water leaves through the pipe h. At this moment the valve 5, 7 is raised from its seat by a manually operated chain m by means of;

which the lever ll, u is operated whereby the 'valve 6 is closed and thepipes D, C are opened. Water can now flow out of the chamber B through the channel I), as the valve 5 has been opened at the time the, valve 6 was closed and efl'ect a. suction of gas through the pipe 0 while at the same time the float (Z sinks and the valve 3 is closed through the medium of the cam 00. After the liquid has been'let out, the valves 5, and 7 are allowed to resume their seats by their own weight after the interruption of the manual operation of chain m whereby the valve6 is opened so that the liquid can reach the chamberBthrough the pipe 1) and raise the float (Z and effect the introduction of gas through the valve 1 into the chamber A, the gases being prevented from escaping into the pipe (4 by the valve hen the float has reassumed its original position, an electric circuit is closed by the sector 8, contact 9' and leads 7, 7" thus producing at the sparking plug 6 a spark tor the ignition of the gas contained in the chamber A.

From this moment, the device begins to operate constantly and automatically. While the explosion is being produced, the pressure resulting from the expansion of the burntgases, and acting on the surface of the liquid in the chamber A, will close the valves 8 and 9 whereas the valve 7 will open under the action of the liquid flowing through the pipes (l, D and through the outlet pipe h. The valve 5 which opens at the same time, allows the water to flow out of the chamber 13 whereby fresh gas is drawn in through the pipe a. The float (Z sinks and its cam s mounted on the axis 2) and the rod 5 connected therewith, produce the opening of the exhaust valve 2. When the pressure of the exploded gases ceases, the returning liquid is prevented from rentering the chamber A through the valve 7 which dropping down onto its seat produces the opening of the valve 6 and the closure of the valve 5. Water is thereby forced to enter the chamber B through the valve 6 and again press the gas through the pipe 0 into the chamber A, raises the float (Z and produces a spark at the sparking plug. In the meantime, the deposits of the burnt gases are expelled through the exhaust valve 2 and water can reenter through the valves 8 and 9. The explosion takes place, the above described stages are repeated and the device acts automatically and continuously.

It follows from the above description that owing to the special arrangement of the ex plosion and compression chambers and their connection by means of a compound valve, the chamber B can be readily emptied and the valves are safely operated by the liquid. The ignition is produced in a safe and adjustable manner at the required moment, directly dependent upon the action of the raised liquid. Gas is also drawn in in a uniform and safe manner independently of the height through which the liquid must be raised. Finally the exhaust of the gases takes place adj ustably and completely.
