Description

In the proposed device, a duplex pump with back-acting valves is applied in the piston portions of the cylinder. This pump is enclosed in a reservoir for storing the stock of pumped and cooled pump fluid.

In order to supply one of the two pumped media, a piping system was used, which communicated with each other and the reservoir by means of a distribution valve.

As is known, in existing duplex pumps, a housing is usually used for cooling. In the present pump, a reservoir is used, which significantly burns the capacity of conventional casings, thereby increasing the possibility of cooling the cylinder in the upper part, working at high pressure, thereby undergoing this strong heating.

The proposed device, in contrast to the known ones, has a crane in which there is no lower appendix for displacement, and the channels in the valve are located in different planes.

The air and fluid injection device is, as depicted in the figure, a duplex pump with a pipe / pipe system.

and 2, which communicate with each other and with the liquid storage tank 3 by means of a three-way distribution valve 4. This valve has a stopper for 5 seconds. additional channel 7, which is designed to inform the discharge air valve 9 of the pump with the atmosphere. For the supply of fluid, the valve 4 has a channel 6 which communicates with the tube 2 and the through valve 10.

 If, however, it is necessary to use the pump to inject air entering through the tube (and the valve 9), then the plug 5 is rotated 90 °; the air pump then communicates with the discharge valve-valve 12 through channel 6, tube 2, as well as through the valve 10. Air is drawn in through the valve //.

The operation of the device is similar to the action of a duplex pump, in which with one stroke of the piston in one zaporshnevoy parts suction occurs, and in the other - injection, and with a different stroke of the piston - vice versa.

The subject matter of the invention is 1. A device for injecting air and liquids, e.g.

the nakatnik cylinder or into air tanks of artillery sled rails, with the duplex pump being used with the backward-acting valves in the piston portions of the cylinder enclosed in the reservoir for storing the pumped fluid and cooling the pump fluid, one of the two mediums pumped by the pump, a system of pipes / and 2 is used, communicating with each other and with the tank 3, which stores the liquid, by means of a three-way distribution valve 4, the stopper 5 of which

provided with an additional channel 7, which, when using a pump for supplying a fluid, communicate the discharge air valve 9 of the pump with the atmosphere.

2. The form of the device according to claim 1, characterized in that, in order to use an air injection pump, the tube / discharge valve 9 connected to the system is connected to the valve 5 and, when turning the plug 90 °, report the air pump with the discharge nipple the valve 12 through the channel 6, the tube 2 and the valve through the valve 10.
