Um den Wasserdiurchlaß' entsprechend der Scfoaiumleisituingjdes angewendeten Sdhaumerzieugers jeweils regeln zu können, ist der Zwisichenmischer weiterhin mit einer parallel zum Saiugstrahlapparat liegenden Drucikwasser leitung versehen, welche ein Organ besitzt, mittels dessen der Durchliaßqiuiersichnitt der Umleitung entsprechend der zur Schaumerzaugung im SdhaumsitraMrohr erforderlichen Wassermenge geregelt werden kann. Da ίο durch Veränderung des Wasserdurdhlasses in der Umleitung· die Saugleistung des Saugstrahlapparates beeinflußt wierdlen kann, ist -die Möglichkeit gegeben, mittels des Absperrorgans zugleich auch die Schaiumbildnerzufiuhr zu regieln.To the water passage 'according to the Scfoaiumleisituingj des Applied Sdhaumerzieugers To be able to regulate in each case is the intermediate mixer furthermore provided with a Drucikwasser line lying parallel to the Saiugstrahlapparat, which a Organ, by means of which the Durchliaßqiuiersichnitt the diversion corresponding to the one required for the foam extraction in the SdhaumsitraM pipe The amount of water can be regulated. Because ίο by changing the water flow in the Diversion the suction power of the suction jet device can be influenced, there is the possibility of at the same time to regulate the supply of Schaiumbildner by means of the shut-off device. In der Zeichnung ist die Vorrichtung gemäß der Erfindung veranschaulicht, nand zwiar zeigt"In the drawing, the device is according to Invention illustrated, nand zwiar shows " Fig. ι einen Zwischenmiseher in Verbinidiung mit einem schaiumerzeiugenden Strahlrohr, zum Teil im Schnitt;Fig. Ι an intermediate mixer in connection with a noise-generating jet pipe, partly in the Cut; Fig. 2 und 3 zeigen andere Ausführungsformen, gleichfalls zum Teil im Schnitt.Figs. 2 and 3 show other embodiments, also partly in the cut. Der in Fig. ι in Verbindung mit einem Schaumerzeuger vienanschaulichte Zwisehenmisciher besteht aus einem mittels Kupplungsgliediem ι, ι in 'die DruckwasBerleitung 2 einschaltbarien Rohr, in ■welchem iein Saugstrahlapparat 4 angeordnet ist. Der Saugraium: S des Sajugstrahlappiarates 4 steht mit einer Zuführleitung 6 für den Schaumbildner in Verbindung, die mit einem Schaumbildnerbehälter gekuppelt wenden kann iund ein Organ 7 zur Regelung der Schawmbildneraufuhr besitzt. Parallel zum Saugistnahlapparat 4 ist eine Druekwassieirieitung 8 angeordnet, in welcher dlas zur Regelung des Wiajsserdurchlasses dienende Organ 9 sitzt. Die Vorrichtung arbeitet in folgender Weise: Das durch das Rohr 3 und den Saugstrahlapparat 4 strömende Dnuidkwasser saugt durch idie Leitung 6 Schaumbildner lan und fließt, sich mit idem Schaumbildner vermissend, in die zum Schaumerzeuger 10 fiihreinde Leitung 2. Dier durch die Umleitung 8 fließende DTMckwassierstrom: tritt bei 11 in das Rohr 3 ein, wo er sich dem aus dem Saugsitrahlapparat 4 kommenden Wasser-Schaumbildner-Gemisch beimischt, sio daß einie gleitihmäßig verdünnte Sidhaiumbilidnerlösung erhalten wird. Der Diruckwiaisserstnom und 'die Schia'uimbüdnerzuiuhr können durch jdie Organe 7 und 9 dem jeweiligen Wasser- bzw. Schaumbildnierbedajrf lentspnadhend geregelt werden. Soll -an Stelle eines Schiaunistrahl'es 'ein Wasserstrahl verspritzt werden, Sl° kann durch Schließen, des Organs 7 die SidhaHmibildnerzuf'uhr gesperrt werdeni.The intermediate mixer illustrated in FIG. 1 in connection with a foam generator consists of a pipe which can be switched into the pressurized water pipe 2 by means of coupling members, in which a suction jet device 4 is arranged. The suction area: S of the suction jet apparatus 4 is connected to a feed line 6 for the foaming agent, which can be coupled to a foaming agent container and has an element 7 for regulating the amount of foaming agent. A pressure water line 8 is arranged parallel to the suction device 4, in which the organ 9 used to regulate the water passage is seated. The device works in the following way: The dnuidk water flowing through the pipe 3 and the suction jet device 4 sucks through the line 6 foaming agent and flows, missing each other with the foaming agent, into the line 2 leading to the foam generator 10 : enters the pipe 3 at 11, where it is mixed with the water-foaming agent mixture coming from the suction nozzle 4, so that a lubriciously diluted Sidhaium-bilidner solution is obtained. The Diruckwiaisserstnom and the Schia'uimbüdnerzuiuhr can be regulated by the organs 7 and 9 in accordance with the respective water or foaming requirement. -An target point, a jet of water be sprayed Schiaunistrahl'es a ', S ° can 7 SidhaHmibildnerzuf'uhr werdeni locked by closing, of the organ. Bei dem in/ Fig1.2 dargesiteülten Ausführungs1-In the dargesiteülten in / Figure 1 .2 execution 1 - beispiel ierfoilg1! .die Umleitung des Drudkwajssers durch einen Hiohlriaum'-i 2, welchier durich das Rohr 3 bzw. den -Saqgsitrahiapparat 4 iund einen denselbien umgiebeniden (Mantel 13 -gebildet wind. Dier umgeleiteite Teil des Druckwassers strömt hierbei durch Öffinlungen 14 des Rohres 3 in den Hohlraum' 12 und tritt durch hinter dem Saiugstrahlapparat 4 angeordnete; Öffnungen 15 wieder in das1 Rohr 3 eint.example ierfoilg 1 ! .the diversion of the Drudkwajssers through a Hiohlriaum'-i 2, which is surrounded by the pipe 3 or the -Saqgsitrahiapparat 4 i and a denelbien (jacket 13 - formed. The diverted part of the pressurized water flows here through openings 14 of the pipe 3 in the cavity '12 and passes through behind the Saiugstrahlapparat 4 arranged; openings 15 back into the tube 1 3 one. Zur Regelung - des Wasserdurchliaases ist in 'dem Hohlraum 12 eine mit Öffnungen 16 versehene Scheibe 17 vorgesehen, gegen welche eine zweite, mit entsprechendien Öffnungen versehene Scheibe 18 verschiebbar ist, durch deren Verstellung der Durchlaßquerschnitt der Öffnungen 16 verändert bzw. 'dieselben geschlossen werden können. Die Verstellung der Scheibe 18 'erfolgt beispielsweise durch 'ein Kegelrad 19, welches mit einer Verzahniung der Scheibe· 18 im Eingriff ist 'und welches mittels einies Hebels 20 gedreht werden kann.To regulate the water throughput, an opening 16 is provided in the cavity 12 Disk 17 is provided, against which a second disk 18 provided with corresponding openings is displaceable, by adjusting the passage cross-section of the openings 16 changed or 'the same can be closed. The adjustment of the disk 18 'takes place, for example by 'a bevel gear 19, which with a toothing the disc 18 is engaged 'and which can be rotated by means of a lever 20. Um 'die Saiugleitung des ZwisAenmisehers zu erhöhen, kann derselbe 'eine zusätzliche Saugstnahlpuimpe aufweisen, in welcher mittels eines abgezweigten Teiles des Druckwassers Sdiäumibildner angeslaiugt |und das Wasser-Schaiumbildner-Gemisich in dien Salugnaum des im Drudkwiasserhaupfatriom angeordneten Saiugstrahlapparates hineingeleitet wird.
