The problem being solved by a utility model is pumping liquids, watering crops, extinguishing fire and using it as a mover on floating vehicles.

The technical result achieved by the implementation of the claimed device is the expansion of the range of use of a pulsating pump unit for various conditions of its application.

The task with the achievement of the specified technical result is achieved due to the fact that in the known pulsating pump installation - propulsion device containing a combustion chamber with a spark plug, a channel for supplying a pumped medium, an intake and exhaust valve, a device for preparing and supplying a fuel mixture, according to the proposed useful models, the combustion chamber is made of two sections in communication with the displacement chamber through the channel, one section is connected to the device for preparing and supplying the fuel mixture and abzhena inlet

valve, in another section an exhaust clan is installed, the displacement chamber is placed in the pumped medium and has an input device made in the form of a check valve and an output device. In the embodiment of the proposed pulsating pump installation - propulsor, a float valve or non-return valve can be installed in the channel connected to the displacement chamber. The output device from the displacement chamber can be made in the form of a check valve or a resonance tube.

The figure 1 shows the proposed pulsating pumping unit - propulsion device in the embodiment, its use as a propulsion device on a floating vehicle.

The figure 2 shows an embodiment of the proposed pulsating pumping unit - propulsor in the embodiment of its use as a pump.

The figure 3 shows an embodiment of the proposed pulsating pump installation - propulsor, in the installation option of the float valve.

A pulsating pump unit - propulsor (see Fig. 1) consists of a combustion chamber 1 with a spark plug 2, channel 3 for supplying a pumped medium. Candle 2 can be glow or spark. The combustion chamber is made of two sections 4 and 5, communicating with the displacement chamber 6 through the channel 7. Section 4 is connected to the preparation and supply of the fuel mixture 8 and is equipped with an inlet valve 9. An exhaust valve 10 is installed in section 5. The displacement chamber 6 is placed in the pumped Wednesday 11 and has an input device 12 with a check valve 13 and an output device 14. The output device 14 can be equipped with a resonant tube 15 or a check valve 16 (see Fig. 2). A check valve 17 or a float valve 18 can be installed in the channel 7 (see Fig. 3).

A pulsating pump unit - propulsor operates as follows.

The fuel mixture, which may consist of a mixture of gasoline, nropane or other fuel with air from the device 8, enters through the valve 9 into section 4 of the combustion chamber 1. When the concentration of the fuel mixture in the region of the glow plug 2 reaches the lower flammability limit, the fuel mixture ignites. When using spark ignition, an electrical impulse can be supplied after a certain period of time. By the pressure of the expanding gases, the valves 9, 10, 13 are closed and a portion of the liquid is pushed out of the displacement chamber 6. The liquid flows out of the outlet device 14, entraining some of the exhaust gases with it. Valve 16 inhibits the reverse flow of fluid. When installing the resonant tube 15, the vacuum in the displacement chamber occurs due to the inertia of the moving fluid. The pressure in the combustion chamber drops, and valves 9, 10, 13 open. The exhaust gases remaining in the combustion chamber are removed through valve 10 and are displaced by a fresh portion of the fuel mixture entering through valve 9. The fluid enters the displacement chamber through valve 13. The cycle repeats. To increase the reliability of operation and increase productivity, a check valve 17 can be installed in channel 7 to prevent liquid from entering the candle 2. Instead of a check valve, a float valve 18 can be installed that performs the same function.

This embodiment of a pulsating pump unit - propulsor allows you to expand the range of its use for various conditions of its application. It can be used for pumping liquids, irrigation of crops, fire fighting and as a mover on floating vehicles.
