- a valve 16 for opening and closing the liquid discharge line 12 which in the exemplary embodiment is a check valve with a spherical closing body, which closes the liquid discharge line 12 when a flow directed against the liquid container 9 or against the pressure chamber 11 occurs
- the pressure chamber 11 has a further inlet 18 which is controlled by a valve 17 and to which a ventilation line 19 is connected.
- the inlet 20 of the gas into the pressure chamber 11 in the position of use that is to say from a frontal view of FIGS. 1 and 2, at the top and the inlet of the liquid line 13, ie the branch 14, is arranged at the bottom.
- the arrangement 10 has a connection 23 between the pressure chamber 11 and a suction line 7 of the compressor 2, the suction line 7 of the compressor 2 in the flow direction of the gas after the branching for the connection 23 to the valve 17 and further to a valve 17 controlled inlet 20 of the pressure chamber 11 has a further valve 8 for opening or closing the suction line 7 with respect to the environment.
- the liquid is pressurized by the gas with a pressure which changes so alternately between two pressure levels is that the liquid flows in at a low pressure level and is conveyed in the desired conveying direction by applying the higher pressure level.
- the arrangement 10 at the low pressure level veau there is a negative pressure so that the liquid is sucked in and there is an excess pressure when the higher pressure level is applied.
- connection with a suction line 7 of the compressor 2 it is of course also possible to generate the required negative pressure with an additional compressor and to connect this to the connection 23.
- the arrangement 10 has a connection 22 between the liquid drain 12 and the pressure vessel 4.
- a further valve 6 for controlling the introduction of the gas into the liquid discharge line 12 is arranged in the connection 22.
- Valves 5, 6, 8 and 16 are initially closed, valves 15 and 17 are open.
- the connection between the liquid container 9 and the pressure chamber 11 is arranged below the liquid level N1 of the liquid container 9, so that the liquid in the liquid container 9 to the liquid level N1 and in the pressure chamber 11 due to the suction function of the negative pressure described below to the much higher Liquid level N1 'extends.
- the valve 5 By opening the valve 5, the gas under pressure is introduced into the pressure chamber 11, whereby the liquid is displaced to a lower liquid level N2.
- the valve 15 is closed and the valve 16 is opened so that the liquid penetrates further into the liquid discharge line 12, an equal amount of liquid being moved from the liquid discharge line 12 to the corresponding liquid consumer.
- the cleaning liquid is pressurized with a gas under pressure before it emerges and is thereby additionally accelerated, as a result of which the liquid has a higher momentum after the outlet.
- the application of the flowing cleaning liquid is selected.
- the valve 5 is now closed and the further valve 6 for controlling the introduction of the gas into the liquid discharge line 12 is opened - or it can, in reverse order, first the further valve 6 for controlling the introduction of the gas opened in the liquid discharge line 12 and then the valve 5 are closed - whereby the gas is passed into the liquid discharge line 12 in both alternative method steps and the pressurized cleaning liquid is pressurized according to the invention, whereby the cleaning liquid according to the invention is additionally accelerated and the Liquid has a higher momentum after the leak. Furthermore, the liquid located in the liquid discharge line 12 is pressed again, so that liquid is again moved to corresponding liquid consumers.
- valve 16 and also the valve 6 and the valve 8 are now closed and the valve 17 is opened, as a result of which the gas located in the pressure chamber 11 is passed to the compressor 2 via the ventilation line 19 and the suction line 7 and a negative pressure is created in the pressure chamber 11. Due to the negative pressure or, in the event that the valve 15 is not a non-return valve, external control now opens the valve 15, so that liquid is sucked into the pressure chamber 11 from the liquid container 9 by the negative pressure prevailing in the pressure chamber 11. The valve 16 is held in the closed position. Now valve 17 is closed and at the same time valve 8 is opened again. This process is now repeated as long as fluid delivery is required.
