The invention relates to obs satisfaction for the delivery of a liquid under pressure and can be used for cleaning highly contaminated internal g surfaces.

FIG. 1 shows the proposed device, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 is a view B in FIG. 1;: in FIG. 4 shows an embodiment 10 of the implementation of the radial valves of the stem and the dispensing cavities of the cylinder heads.

Fluid dispenser. under pressure, it includes a piston, double-acting, 15-soy, containing a 1DILINDR 1, inside of which a piston 2 is placed, which divides the cylinder cavity into two working chambers 3,4. Along the ends of cylinder 1, differential pistons 5, 6, 6 are arranged, which are connected to each other via feedback channel 7 and act as suction and delivery channels.

In one embodiment (Fig. 1), each of a number of radial channels 17, 18 is formed along a helical line and communicates with annular dispensing cavities 28, 29 made in its own. the turn on the surfaces of the caps 13, 14, covering the rods 15, 16.

The annular dispensing cavities 28, 29 are connected to the corresponding} outlets 11, 12 by dispensing channels 30, 31.

On the rod 6 is made of radial channels-nozzles 32.

In another embodiment (Fig. 4), each row of radial channels 33, 34 is made annular, and razdatkan: e cavity 35, 36 - along a helical line.

The covers 37, 38 have face protrusions 39, 40 so that they can accommodate the dispensing cavities along a helical line. The end protrusions 39, 40 are sealed along the edges with respect to the drive rod 41 and the suction channels 8 connect the power rod 42 with annular seals.

The barrel chambers 3.4 with the inlet 9 of the supply line, and the delivery channels 10 connect the chambers 3.4 with the outlets 11,12. The cylinder is bounded by elongated caps 1.3, 14.

The piston 2 has a drive rod 15 and the output rod is located opposite to the drive side.

16. Drive 15 and output 16 rods are made with a number of radial channels

17.18 respectively.

Each radial channel 17 communicates with its corresponding axial channel 19, which is made in the rod 15, and each radial channel 18 communicates with the corresponding 16-axial channel 20, which is made in the rod.

The device includes means for discharging fluid, made in the form of a ball head 21 connected to the output rod 16. The ball head is divided into several sectors 22-2f, on the surface of each of which a group of orifices 27 are drawn, forming several concentric circles due to the fact that nozzles 27 lying on the common radius of each sector are associated with one of the axial channels 20 of the rod 16 or channel 19 of the rod 15.

The rod 15 is connected to the mechanism, its reciprocating movement (not shown).

In one embodiment (Fig. 1), each of a number of radial channels 17, 18 is formed along a helical line and communicates with annular dispensing cavities 28, 29 made in its own. the turn on the surfaces of the caps 13, 14, covering the rods 15, 16.

The annular dispensing cavities 28, 29 are connected to the corresponding} outlets 11, 12 by dispensing channels 30, 31.

On the rod 6 is made of radial channels-nozzles 32.

In another embodiment (Fig. 4), each row of radial channels 33, 34 is made annular, and razdatkan: e cavity 35, 36 - along a helical line.

The covers 37, 38 have face protrusions 39, 40 so that they can accommodate the dispensing cavities along a helical line. The end protrusions 39, 40 are sealed along the edges with respect to the drive rod 41 and the output stem 42 with annular seals

43

The communication zone of the radial channels 33 with the dispensing cavity 35 of the rod 41 is displaced relative to the overlap zone of the radial channels 34 with the dispensing cavity 36 of the rod 42 by 180 °.

In the working chambers of the cylinder (FIG. 4), valves 43 are located. The device operates as follows.

The ball head is inserted into the throat 44 of the tanker 45, the inner surface of which should be cleaned, ji fix the device on the throat 44.

When the pump is operating, the ball head makes reciprocating movements in the cavity of the tanker 45. In the first phase of the cycle, when the ball head rises up, the differential piston-valve 6 ensures that the working chamber 4 is filled with cleaning fluid by combining one of the inlet pipes 9 with the suction channel 8, and through it with the camera 4.

At the same time, the valve, through its discharge channel 10, connects the working chamber 3 with the outlet opening 11. The washing liquid entering through the dispensing channel 30 completely fills the space of the dispensing cavity 28. At the same time

the liquid from the dispensing cavity 28 under pressure alternately injects into the radial channels 17, since as the driving rod 15 advances, the channels 17 are sequentially communicated and separated by the dispensing cavity 28. Moreover, the combination of the dispensing cavity 28 with the next radial channel 17 occurs in such a way that the radial channel 17 begins at the moment of closing the previous one, thereby a smooth transition occurs, and the possibility of hydraulic shock is eliminated.

From each radial channel 17, the fluid passes through the corresponding axial channel 19 and is ejected at high speed in the form of successive discrete jets from the nozzle openings 27 of sectors 22-26. Each jet is sprayed simultaneously by nozzles 27 located on a common radius. During the entire phase of upward movement of the rod 15, the nozzles 27 are periodically turned on along the radius and thus the jets are sequentially ejected in a circle of sectors 22-26.

In the second phase of the cycle, when schA. The head falls down, the working chambers 3 and 4 change their roles: in the chamber 3 a suction stroke occurs, and in the chamber 4 a discharge occurs. At the same time, the washing liquid from the outlet 12 through the dispensing channel 31 continuously enters the dispensing cavity 29. The radial channels 19 alternately supply discrete jets from the dispensing cavity 29 to the axial channels 2-0 and, therefore, to the nozzles 27, but in the opposite direction. direction, since the order of the connection of the radial of the ath channels 19 with the dispensing cavity 29 is reversed.

The distance between adjacent rows of nozzles 27 determines the zone of action of these jets in such a way that, with the successive action of these jets, taking into account the partial overlap of their edges, the entire inner surface of the tanker is washed. In addition, the combination of the reciprocating movement of the ball head with a periodic change in the direction of rotation of the traveling waves, is formed by

by the addition of separate jets, causes the latter to curl and, as a result, high-quality cleaning of the tank walls. The cleaning efficiency is also enhanced by the fact that the jet always acts on the contamination directly, and not through the water film. In this case, a significant fraction of the energy of discrete jets is used, since the latter do not intersect in space and therefore do not quench them with each other. Significant value

Ie-G reduction in the consumption of washing liquid.

In the embodiment of FIG. 5 by interconnecting the outlet openings 12 and 11, the radial channels 33 and 34

communicated through screw dispensing cavities 35 and 36 with both working chambers during the entire cycle. At the same time, the axial channels 19 of the rod 41 and 20 of the rod 42, lying on the common

axes communicated with each other.

The displacement of the overlapping zones of the cavities 36 with the radial channels 33, 34 by 180 ° ensures simultaneous movement in a circle of sectors of the two bottoms

metrically opposed jets, which dramatically increases the degree of cleaning of the tank walls and reduces the cleaning time.
