    rial on complexly shaped products.
    This goal is achieved by the fact that in the spray device for coating the inner stacks of a hollow product containing a spray barrel with a nozzle at its output end, the spray barrel is provided with a mounting collar for fastening it on the outer surface of the products in a predetermined position.
    In addition, the spray device is equipped with a servomotor with a time controller for providing a predetermined duration of spraying,
    FIG. 1 shows a spray gun which forms part of a spray device, a side view; on Fig.2 spray device with the processing object; in fig. 3 - flexible front part of the spray barrel; in fig. 4 is a spray device connected to the control unit.
    The spray device in the form of a spray gun for coating the inner walls of a hollow product comprises a spray barrel 1 with a nozzle 2 at its outlet end and an installation collar 3 for fastening it on the outer surface of the product 4 in a predetermined position.
    In addition, the spray device comprises a handle 5, a trigger 6, and a pneumatic servo motor 7 with a time controller for providing a predetermined spraying duration, which is controlled by the trigger 6 to adjust the flow rate valve 8. The spray device is equipped with a spray pipe 9, into which the material flows under pressure through the line 10 and the valve 8 of the material flow.
    The spray device is connected to an AND coupling unit, which has an inlet 12 for connecting to a compressed air line. The connecting unit 11 is provided with means 13 for quick connection, as well as through other means 14 for quick connection, it is connected to the front part 15,
    Compressed air can be supplied through the inlet 12 to facilitate the flow of material for spraying through the front part 15 of the spray barrel 1.
    To obtain the desired position of the jet, the spray barrel 1 is introduced and the cavity of the product 4 through the inlet 16.
    FIG. 2 shows a product, the cavity of which has a special shape and, when the inlet 16 has a certain location relative to the cavity, it is quite essential that
    the spray barrel 1 was inserted precisely to obtain the required coating on the inner walls of the product.
    The spray barrel 1 must be fastened precisely with respect to the cavity of the product in the direction, angle and depth of insertion. This is achieved by means of an installation collar 3, which is rigidly attached to the spray barrel 1. The adjustment collar 3 is designed so that the spray barrel 1 can be installed in the desired position by engaging with the outer surface of the product 4 through the opening 16.
    In order to obtain an accurate distribution of the coating material in the cavity, it is necessary that the spray barrel 1 and the installation collar 3 fit each friend at a point of entry. The configuration of the insertion point is determined by the shape of the cavity and the location of the inlet opening with respect to it. A good coverage of the cavity is obtained by inserting the spray barrel 1 through the inlet 12 and is provided by combining the mounting collar 3 with the outer surface of the product 4, and the front part 15 of the spray barrel 1 should be tough. To facilitate use of the spray device at such entry points, the front portion 15 may have a flexible section between the mounting collar 3 and the means 14 for quick connection,
    The servomotor 7 of the spraying device has two pistons 17 and 18 attached to a common rod 19. In the spraying device, the fixed intermediate wall 20 together with the pistons 17 and 18 form three separate chambers 21, 22 and 23, of which the chambers 21 and 23 are connected with a friend through a channel in stock 19.
    When all three chambers 21, 22 and 23 of the servomotor 7 are under pressure, the material flow valve 8 remains closed, and when the chambers 21 and 23 are not under pressure, the valve 8 is open.
    The control unit 24 is connected to the spray gun through the tubes 25, 26 and 27. The tube 27 is connected directly to the chambers 21 and 23 of the servomotor 7, the tube 26 is connected to the chamber 22, and also to the trigger valve 28. The tube 25 is connected only to trigger 6.
    The control unit 24, which is connected to the source 29 of compressed air through a filter, contains a control valve 30, which through the tube 27 controls the air pressure in the chambers 21 and 23 of the servomotor 7. The control valve 30 has a NO operation mode, which means It is open in a free position, in which it provides communication between the chambers 21 and 23 and the source 29 of compressed air. The control unit 24 is designed to make direct contact between the air source 29 and the chamber 22 of the servomotor 7 through the tube 26. In the YES mode, the valve 30 is intended to connect the left-hand side of the valve 31 to the compressed air source 29, thereby closing the control valve 30. The left-side portion of the valve 32 operates in the NO mode and is connected to the trigger valve 28 of the spray gun through the tube 25. The left side of the valve 32 is pressed to the closed position when the trigger Left valve 28 is not actuated. When the trigger valve 28 is depressed, the left side of the valve 32 is released and the valve 32 is moved from the closed to the open position. The inlet of the valve 32 is directly connected to the source 29 of compressed air. When valve 32 is actuated, valve 31 opens. Between valves 31 and 32, a periodically operating valve 33 is installed, which is described later, and valve 34 operating in the NO mode. There is a synchronizing means 35 consisting of valve 34 and valve 33 36 variable throttling and tank 37. In addition, the spraying device has a safety valve 38 with which the tubes 25 and 26 can be interconnected. This is achieved by turning the head 39. The safety valve 38 is designed to provide continuous pressure on the left side of the valve 32, which means that the spray device does not work. The operation of the spray device is as follows. When the control unit 24 is connected to the compressed air source 29, the pressure enters the chamber 22 of the servomotor 7 through the tube 26. Due to this, the chamber 22 is under pressure. At this time, the air pressure reaches the control valve 30, which rises to the left position shown in FIG. 4. In this position, the valve 30 passes air pressure through the tube 27 and the chambers 21 and 23 of the servomotor 7. The pressure from pressure: pressure on the piston of the servo motor 7 is equal in both directions, so the pressure load acting on the left piston 17 in the chamber 21, which will be determining to obtain an exerting force for the valve 8 of the material flow rate. at the same time, the air pressure reaches the trigger valve 28, which is in the off position (see FIG. 4) and allows air to pass to the left side of the valve 32 through the tube 25. The right side and also the inlet of the valve 32 are directly connected to the source air pressure, however, due to the fact that the cross section of the right side of the valve is smaller than the cross section of the left side of the valve, the valve is kept in the closed position on the right side. A compressed air source is also connected to the right side of the valve 31, which has a YES mode of operation. Due to the fact that the left side of the valve 31 is not under pressure, the valve is held in the left position, closed. When the trigger valve 28 is actuated, the pressure applied to the left side of the valve 32 is interrupted, which means the valve is shifted to the left, to the open position. Now the air pressure can flow to the valve 33, which, in turn, allows air to reach the inlet, as well as to the right side of the valve 34. The latter is thereby displaced in the direction of the left, open floor. The air deflation can now fall into the left side of the valve 31 and, since its left side of the valve has a larger cross section than the right side, the valve 31 is displaced to the right, to the open position. As a result, the air pressure reaches the left side of the control valve 30. Due to the difference in cross section between the right and left sides of the valve 30, the latter is shifted to the right. In this position, the valve 30 is connected to the chambers 21 and 23 of the servomotor 7 and the atmosphere. The constant pressure in the chamber 22 drives the piston 18, the piston rod 19 and the material flow valve 8 to the right. When the spray device through line 10 is continuously connected to a pressure source, opening the valve 8 means the start of spraying. When the air passes through the valve 32 and the valve 33, the air is supplied to the synchronizing means 35. Due to this, the air passes the limiting valve 36 and enters the tank 37. Since it is closed, the pressure in it will increase sequentially until a full pressure. Total pressure is the pressure of the compressed air source. When the total pressure is reached, the pressure load on the left side of the valve 34 will dominate and the valve 34 will shift to the closed position.
    Now the left side of the valve 31 is without pressure and the valve 31 is displaced to the left, due to which the left side of the control valve 30 is opened. The servomotor 7 actuates the material consumption valve 8, moves it to the closed position, and spraying stops.
    The spraying time is determined by the time interval that is necessary for the formation of pressure in the tank 37 through the restrictive valve 36. The required time interval for spraying can be selected by adjusting the cross section of the restrictive valve 36.
    This spray device is fully automatic and provides a certain time interval for operation, due to which the required amount of materials passes through the trigger valve 28, while there is no problem of adjusting the duration of its operation. If, for example, the trigger valve 28 is operated for too short a period of time, then the valve 32 cuts off the air supplied to the variable valve 33, the valve 34 and the synchronizing means 35. Due to the fact that the air pressure accelerates the opening of the valve 31, the valve 33 will change position so that instead of the valve 34 and the synchronizer 35 supply air under pressure through the valve 31. As a result, the spraying operation continues until the full pressure in the tank 37 is obtained, as described earlier.
    In the event that the trigger valve 28 is activated for too long, the spraying operation is stopped as soon as the pressure in the tank 37 becomes large enough to close the valve 34, thereby stopping the supply of pressure to the left side of the valve 31. The valve 31 closes , and the pressure is continuously acting on the right side of the control valve 30, moving it to the open position.
    The use of this spraying device allows obtaining exact product positions and spraying direction in the cavity, as well as spending the required amount of material. Thereby, sputtering in the cavity can be performed very quickly and at the same time an effective and evenly distributed coating is obtained on the surface. You can achieve optimal usage time and the right amount of material.
