    The liquid slug projector apparatus is entirely pneumatically operated. It comprises a generator having a main housing whose main port fluidly communicates with a liquid body. A first shuttle and a second shuttle are slidably mounted inside the main housing. The first shuttle forms with the main housing a slug chamber for confining therein a liquid slug. A pneumatic source together with a pneumatically-operated valve cyclically cause the shuttles to move relative to or in locked condition with each other, thereby applying during each cycle of operation an abrupt propulsion force to the confined liquid slug which becomes expelled as a very high-velocity liquid jet through the main port.

    The invention relates to seismic exploration, to means for generating acoustic impulses in water.
    The aim of the invention is to simplify the design and facilitate maintenance.
    Fig. 1 shows a vertical section of the acoustic generator, the first core is shown in the ready to shoot position; in fig. 2 is the same when the first core is at the lowest point of its movement and the liquid pool is thrown at high speed into the surrounding water; FIG. 3 is the same when the second core is moving down; 4 is the same when the second core is at the lowest point and locks the first core; Fig. 5 shows closed first and second cores in the process, and no return movement; fig.b - pneumatic valve.
    l
    The device 1 is controlled only by compressed air and consists of an acoustic generator 2, which creates an acoustic pulse in the surrounding water 3 by means of a liquid bullet 4 ejected at a very high speed and forming a liquid jet 5 flying in direction 6 (Fig. 1 and 2 ).
    The generator 2 consists of a cylindrical housing 7, which has inside the bore small 8 and large 9 diameters. The housing 7 is provided with an upper 10 and lower 11 bottoms. In the bottom 11 there are piston seats 12 and an outlet (exhaust) channel 13 immersed in water during operation. The top plate 10 is provided with a passage 14.
    Inside the bores 8 and 9 are mounted movable first 15 and second 16 cores (Fig.1-2). The pneumatic device 17 (Fig. 6), together with the three-way valve 18, alternately controls the first 15 and second 16 cores, causing them to move jointly or relative to each other.
    The first core 15 consists of a lower piston 19, an upper main piston 20 and a connecting piston 21. Both pistons have sealing rings 22 (FIG. 1-2). The second core 16 also consists of a lower piston 23, forming a passage 24, an upper piston 25 and a connecting shaft 26, provided inside with a cylindrical bore 27. Pistons 20, 23 and
    25 are also mounted inside the cavities formed by the bores 27, 8 and 9, respectively, and are also movable and provided with sealing rings. 5 A bore 8 forms a chamber 28 with a bottom 11 and a piston 19. A main chamber 29 is formed between the piston 23 and 25 and the housing 7 with a torque of 9. The bottom 11 and the piston 23 form the piston seats 12 and 30 (Fig. 1 - 2) respectively. The bottom 11 works as a stopper dp piston 19, and hence dp piston 23.
    Inside the bore 27 and below the piston 15, a trigger chamber 31 is formed. The inner passage 32, going through the piston 25 into the chamber 31, is connected to the inner passage 33, leading through the piston 25 to the chamber 29, using a means controlled by a solenoid valve 34, mounted inside the bore of the sleeve 35, which directly emanates from the piston 25, as if it were elongated. The sleeve 35 is movably placed in the passage 14 and provided with a seal.
    The electric cable 36 is periodically fed control pulses to the solenoid valve 34. The chamber 30 29 is directly connected to the pneumatic installation 17 via the external line 37.
    The return chamber 38 is formed between the piston and the upper bottom 10
    35 (fig.Z). The housing 7 with the bore 8 forms a ventilation chamber between the pistons 19 and 23 (chamber .39). This chamber is connected to the pneumatic valve 18 through an internal passageway.
    0 which is nets longitudinally across the entire core 16 (FIG. 3).
    When the chamber 39 shrinks to its smallest size (Figures 1, 4 and 5), it begins to ventilate for 5 seconds into the external space through a normally closed: valve 34, which mechanically opens at this moment, and the internal longitudinal valve 41. Valve 42 is mounted inside the piston 23 and is provided with a plunger 43 passing through the hole in the seat of the valve 42. The valve itself is provided with a seal.
    In Fig. 6, the pneumatic installation 17 has an air compressor 44, which is provided at the outlet of the pressure regulator with a pressure 45 connected directly to the reservoir chamber 29 via line 37. Pipeline 40
    connects valve 18 to the ventilation chamber 39. Valve 18 consists of a housing having bores 46, 47 and 48, in which pistons 49, 50 and 51 are placed along the running fit, respectively. These three pistons form together the core 52 of the valve 18, the pistons 49 and 50 are provided with an o-ring seal, while the piston 51 does not have a seal and moves inside the bore 48 with some clearance.
    Above the piston 49, an upper chamber is formed, 53 and below the piston 50 - the lower chamber 54. The upper chamber 53 is permanently connected to the pneumatic installation 17 through the axial bore 55, the diametrical openings 56, the pipe 57 and the line 37. The lower chamber 54 is permanently connected to the vent camera 39. through line 40, and camera 48 - with the return chamber 38 through pipe 58.
    When the core 52 is in its lowest position (Figures 1 and 6), its central piston 51 fits snugly on the lower seat 59, and the upper saddle 60 is free, whereby the return chamber 38 is ventilated to the surrounding space through line 58, chamber 48 and handset 61.
    When the core 52 is in its extreme upper position (Fig. 2), the piston 51 fits tightly on the upper seat 60 and releases the lower seat 59, with the result that the return chamber 38 is disconnected from the environment and connected to the pneumatic assembly 17 through the passage 58, chamber 48, passage 57 and line 37. Thus, valve 18 connects the return chamber 38 either to the environment through the passages 58 and 61, or to the pneumatic installation 17 through the passages 58, 57 and line 37.
    When the ventilation chamber 39 is reduced to its smallest volume (Figures 1, 4 and 5), the plunger 43 rises and raises the valve 42. Thus, the chamber 39 is vented to the environment through the valve 42 and the channel 41, and the lower chamber 51 of the valve 18 also vented to the environment through pipeline 40, the ventilation chamber 39, the valve 49 and the channel 41. The chamber 31 is permanently connected to the channels 41

    cut the flow hole 62 above the piston 25 (figure 2)
    11p preparing the generator for firing compressed air is supplied to line 37, passages 57, 56; 55 and chambers 29 and 53. The core 52, under the pressure applied from above, occupies the lowest position than it connects the return chamber 38 to the environment through the passage 58, the chamber 48 and the vent tube 61.
    The device works as follows.
    In figure 1, the generator 2 is shown ready for shooting. In this position, the core 52 is in the extreme lower position. The compressed air is in chamber 29, and the solenoid valve is closed.
    When the starting electrical impulse is passed through line 36 (FIG. 2), valve 34 opens for the duration of the pulse, connecting chamber 29 and 31. At this moment, the compressed air from chamber 29 enters chamber 31 and begins to press on piston 20. As soon as the piston 20 will move from its place at the extreme upper point, tightness is immediately broken between the cone 63 and the seal of the lower piston seat. The area affected by pressure instantaneously increases and becomes equal to the entire area of the piston section 19. As a result, the core 15 goes down with a sharp jerk.
    At the same time, the core 15 is separated from the core 16 and the compressed air from the chamber 29 fills the chamber 39, and the plunger 43 moves down, closes the valve 40 and the chamber 39 locks. Thereafter, the compressed air from the chamber 29 ceases to be choked into the water.
    As soon as the core 15 finishes its impact, the liquid pool, located inside chamber 28, is ejected at a very high speed and forms a liquid jet with a high internal pressure, which, exploding, creates an acoustic impulse in the surrounding water.
    When the core 16 moves downward, the valve 34 is normally closed until the end of the motion of the core 15 ends. Chamber 39 receives compressed air from chamber 29 and delivers it to the lower chamber 54 of valve 18 through passage 40 (Fig. 6).
    Since the cross-sectional area of the piston 50 is larger than the cross-sectional area of the piston 49, a force is created which drives the core 52 upwards. Moving, the core 52 reaches the uppermost position and the piston 51 fits tightly onto the seat 60.
    The passage 58 and the chamber 48 are disconnected from the vent tube 61. As a result, the return chamber 58 also begins to disconnect from the environment 3 and is connected to the pneumatic installation 17 through the passage 58, the chamber 48, the passage 57 and the line 37. Compressed air from the compressor 44 begins to flow into the return chamber 38. The cross-sectional area of the upper piston of the core 16 is adjusted so that when the pressure in the chambers 29, 39 and 38 is equalized, there is a force that moves the core 16 down (FIG. 3), which sits on the first core 15, thereby opening the valve 42 (Fig.6).
    When the piston 19 is compacted with a conical surface 63, the chamber 39 is fully ventilated into the environment through the open valve 42 and the channel 41. At the same time, the air from the chamber 31 continues to be slowly released into the environment through the passages 62 and 41 in the piston 25.
    When the cores 15 and 16 move backward, when the valve 34 is closed, the chamber 29 is filled with compressed air through line 37. With the valve 42 open, the ventilation chamber 39 and the lower chamber 54 of valve 18 are ventilated through the channel 41 to the environment, which allows the core 52 move to the lowest position while the return chamber 38 begins to disconnect from the pneumatic installation 17 and switch to the surrounding environment.
    The compressed air contained in the return chamber 38 will be ventilated to the environment. When the chamber 38 is fully ventilated, the first and second cores 15 and 16 closed together return to their uppermost positions ((ng.5) due to the difference in the areas of the pistons 23 and 25. The generator 2 is now ready for the next cycle of operation.
    . The compressor 44 and the pneumatically controlled valve 18 are connected to the generator 2 and the compressor delivers
    compressed air into the main chamber 29. A normally closed, electrically controlled valve 34 is connected between the main chamber 29 and the trigger chamber 31. After the valve 34 has been activated, the compressed air from the main chamber 29 rushes into the trigger chamber 31 and sharply advances the first core 15, which leads to the ejection of a liquid bullet and the formation of a liquid jet.
    The pneumatically controlled valve 18 supplies compressed air from the compressor 44 to the return chamber 38,
    causing the movement of the second core 16 towards the core 15 and to locking it, thus stopping the entry of compressed air into the main chamber 29. This causes movement
    closed cores 15 and 16 back to their original position, which completes one cycle of operation of the generator.
    The application of the invention allows to simplify the design and facilitate the maintenance of the generators of acoustic signals in a liquid.
