Wie aus der Zeichnung hervorgeht, ist 1 der Druckzylinder, welcher durch den Stutzen 2 mit dem die Steuerungsteile aufnehmenden Gehäuse 3 in Verbindung steht. In dem Druckzylinder 1 ist der zweckmäßig als Glocke ausgebildete Schwimmer 4 angeordnet, dessen Stange 5 mit dem Ventilkörper 6 in Verbindung steht. Dieser Ventilkörper 6 legt sich, sobald der Schwimmer seine untere Lage einnimmt, auf den Boden 7 der Kammer 8, welche durch Öffnungen 50As can be seen from the drawing, 1 is the printing cylinder, which is through the Nozzle 2 is connected to the housing 3 receiving the control parts. The float 4, which is expediently designed as a bell, is arranged in the pressure cylinder 1, the rod 5 of which is connected to the valve body 6. This valve body 6, as soon as the swimmer assumes its lower position, lies down on the floor 7 of the chamber 8, which is passed through openings 50

" mit dem Zylinder 1 in Verbindung steht. Sobald der Schwimmer jedoch in seine obere Lage geführt wird, legt sich der Ventilkörper 6 gegen den Ventilsitz 10, in welchem Falle die Kammer 8 von der Kammer 9 abgeschlossen wird. Die Kammer 9 steht durch Kanal 11 mit der Kammer 12 in Verbindung, welche durch das zweckmäßig als Lippenventil ausgebildete Druckventil 13 gegen den Raum 14 und die sich an denselben anschließende Druckluftleitung .15 abgeschlossen ist. Der Raum 12 steht ferner durch das Ventil 16 mit dem Raum 17 in Verbindung, in welchen die Luftsaugleitung 18 einmündet."is in communication with cylinder 1. However, as soon as the float is in its upper Position is performed, the valve body 6 lies against the valve seat 10, in which If the chamber 8 is closed by the chamber 9. The chamber 9 stands through Channel 11 in connection with chamber 12, which by the appropriately designed as a lip valve pressure valve 13 against the room 14 and the compressed air line .15 adjoining the same is completed. Of the Space 12 is also through the valve 16 with the space 17 in connection, in which the air suction line 18 opens.

Die Wandung des Gehäuses 3 ist auf ihrer Innenseite bei 19 mit Gewinde versehen, welches das Muttergewinde für den GehäuseteilThe wall of the housing 3 is provided on its inside at 19 with a thread, which the nut thread for the housing part

20 bildet. Dieser wird bei 19 in das Gehäuse 3 eingeschraubt und legt sich mit seinem Flansch20 forms. This is screwed into the housing 3 at 19 and lies down with its flange

21 gegen den untersten Teil 22 des Gehäuses 3. Der Teil 20 steht durch Stutzen 23 mit dem Außenraum in Verbindung und nimmt bei 24 den Dreifuß 25 auf, welcher oben mit der Dichtungsscheibe 26 versehen ist. Der Innenraum· des Teiles 20 steht durch öffnungen 27 mit dem ihn umgebenden Raum des Zylinders 3 in Verbindung. In den Zylindern^, 20 ist ein Stufenkolben verschiebbar gelagert, welcher im wesentlichen aus den drei Hauptteilen 28, 29, 30 besteht. Der Teil 28 besitzt unten die Stulpendichtung 31, mit welcher er in dem Zylinder 20 gleitet, und ist oben bei 32 mit dem Teil 29 verschraubt, der unten in einen zweckmäßig konzentrisch zum Teil 28 angeordneten, bei der unteren Stellung des Kolbens 28,29, 30 auf der Dichtungsscheibe 26 aufruhenden Zylinder 33 ausläuft. Der Zylinder 33 mündet oben in den weiteren Raum 34, welcher durch die Bohrungen 35, 36 mit dem den Zylinder 28 umgebenden Raum des Teiles 20 in Verbindung steht. Der zwischen Zylinder 33 und dem Kolbenteil 28 befindliche, ringförmige Raum steht mit der im Teil 29 vorgesehenen Bohrung 37 in 'Verbindung.. Der Teil 29 ist oben mit der Stulpendichtung 3821 against the lowermost part 22 of the housing 3. The part 20 is through nozzle 23 with the Outside space in connection and takes at 24 the tripod 25, which above with the Sealing washer 26 is provided. The interior of the part 20 protrudes through openings 27 with the space of the cylinder 3 surrounding it. In the cylinders ^, 20 is a stepped piston slidably mounted, which essentially consists of the three main parts 28, 29, 30 consists. The part 28 has the faceplate seal 31 below, with which it is in the Cylinder 20 slides, and is screwed to part 29 at the top at 32, which is at the bottom in a expediently arranged concentrically to part 28, in the lower position of the piston 28, 29, 30 on the sealing washer 26 resting cylinder 33 runs out. The cylinder 33 opens up into the further space 34, which through the bores 35, 36 with the the space of the part 20 surrounding the cylinder 28 is in communication. The one between the cylinder 33 and the piston part 28 located, the annular space corresponds to that provided in part 29 Hole 37 in 'connection. Part 29 is at the top with face plate seal 38

Claims

which is held by the upper part 30 of the control piston. The upper Part 30 has the bore 39 through which the bolt 40 extends loosely. This lets you see itself and the wall of the bore 39. a room . of annular cross-section free, is above with the sealing washer 41 and below with the in the expanded cylindri-. see space 34 sliding stepped piston 42 firmly connected. The housing 3 is provided with the water inlet nozzle 43, which through bore 44 with the interior of the housing 3 and the housing 20, further through Channel 45 and the passage 47, which can be regulated by means of screw 46, with the upper housing part or pressure chamber 48 is in communication. The mode of operation of the subject matter of the invention is the following:

The water arrives at the point indicated in FIG Position of the control parts through connecting piece 43 and bore 44 in the Housing 20 and through the bores 27 and connecting piece 2 in the cylinder 1. To the extent that as the water in the cylinder 1 rises, the one above the water level becomes Air is compressed until the air pressure is so great that the resistance of the pressure valve (Lip valve) 13 overcome and the compressed air generated through the holes 50.50, room 9, channel 11, room 12, lip valve 13 is pressed into the space 14 and from this into the compressed air line 15. As soon the water level has reached the float 4 and partially washed around it,. 35 the float is raised and the valve body 6 pressed against the seat 10, which prevents further escape of compressed air will. In the meantime, this is the annular space between the part 28 and the Housing 20 flowing through water through holes 36, 35 also in. the space below of the piston 42 arrives, with the result that the piston 42 with the bolt 40 and the sealing washer 41 is raised somewhat 45th will. Now that which has entered the pressure chamber 48 before and a compression there can now the existing air causing water through the annular space 39, hole 37 and the annular space between the cylinder 33 and part 28 escape into the connecting piece 23. After the pressure in the space 48 has been eliminated, the pressurized water acting below the part 29 can affect the entire piston 28, 29.30 lead upwards (Fig. 2), the sealing washer 41 by abutting against the Inner wall of the upper part 49 is pressed back onto the part 30, that is to say the one Assumes a position in which the annular space 39 is blocked from the space 48 again. Now this can be done in the nozzle 43 emerging water no longer get into the pressure cylinder, since the connection of this nozzle is canceled with the pressure cylinder due to the piston displacement. That in the cylinder ι located water, which was used to generate compressed air, can through Nozzles 2 and bores 27 in the housing part 20 and out of this · between the feet of the tripod 25 get into the nozzle 23 and out of this to the outside. The water level in the pressure cylinder 1 will therefore gradually lower itself, the float 4 being released and 'will get into its lower position, in which the valve body 6 opens again the ground 7 rests. While the water is the cylinder 1 marked on the Leaves paths, passes through the bore 45 and passage 47 pressurized water into the pressure chamber 48, where by the influx of water there is a compression of what is there Air causes and a corresponding overpressure is achieved. As soon as the overpressure has reached a certain size, the piston 28, 29, 30 is moved downwards into the in Fig. Ι marked position pressed, whereupon the process described is repeated. D_by the. the openings of the valve passage 47 regulating screw 46 can Water access must be adapted to the respective conditions. It can be seen without further ado that the device works the slower, the more the passage 47 is narrowed by the screw 46 and vice versa.
