The sealing collar 6 could also only be in direct disengaging rotational positions of the spindle bar in a turning of the spindle 4 to form the inflow opening 2 or only the inflow opening 3 ofcincs annular gapcs and fen at their ends, so that only cold or only warm water at 9 be vulcanized close to the spindle. The anord- flows out. In all intervening rotational positions of the sealing collar in a special 5 direction of the spindle, the two inflow openings are un-Biichsc has the advantage that the sealing is open to different degrees, so that at 9 more or Sleeve together with the liner slightly out - less warm mixed water flows out. Will the can be changed. Spindel4 against the locking position shown in Fig.

The spindle 4 has moved one of its outer end faces, so the flow rate decreases. there Axial bore 30 extending from the surface, in which a plunger-type spindle section, which is increasingly connected to the inflow openings by the cylinder operating handle 22, is covered, bcn 31 is axially displaceable. The stroke of the piston when the operating handle is moved axially

31 opposite the spindle 4 is axially limited, and 22 go in the closing direction of the piston 31 and the in the exemplary embodiment in that a cross pin 32 inserted into the spindle 4 for this movement is coupled to one another in a slot direction. As soon as the breakthrough 33 engages the spindle wall. The Boh-Spindel4 has reached the closed position (Fig. 1). is tion 30 extends into the sealing collar 6 of her piston 31 in the already described receiving spindle section and is there way by stopping the coupling member 34 on become free in the embodiment by the valve housing in the spindle. Now he is leading inserted guide pin 12 closed. »° piston 31 when moving the operating

The piston 31 has an overrun in the operating handle 22 in the closing direction. the handle 22 built-in resilient coupling member 34 with by the freedom of movement of the pin 32 in the the spindle 4 is limited for its movements in the closing SchlMzdurchhruch 33. In this remediation - that is to say, for moving the operation, the piston 31 passes over with its front one handle from position F i g. 2 in the position F i g. 1 »5 sealing ring 40 the openings 42 of the spindle wall - detachable. In the exemplary embodiment, this has and then compresses in the displacement 37 Coupling member 34 two within the handle hollow-liquid-air mixture. that also includes room 43 mes on both sides of the piston 31 extending spring and the annular gaps 26 and 28 fills. That condensed donate 35. the with inwardly directed lugs 36 mixture is üiici the check valve 38. the, 3 <> space 43, the openings 44, the annular gap 28 and (FIG. 2), so that when the operating handle is moved, the openings 29 are pushed out into the annular gap 26 provided under the sealing collar towards the closed position (FIG. 1) de) 4 and the plunger 32 moved together. As a result, the sealing collar 6 is in the in will. Shortly before the spindle 4 is in the closed position in FIG has reached, the spring legs 35 slide with their 35 with great force against the wall of the valve housing ·; Ends pressed onto the cap 15 fixed on the valve housing 1, so that the inflow openings 2 and 3 spread apart more and more, the lugs 36 being casually blocked. A backflow of the under release the spindle 4. Now the piston of the sealing sleeve 6 can be compressed mixture 31 compared to the occupying the closed position is prevented in that the sealing ring 41 of the Spindle 4 shifted further in the closing direction 40 seals piston 31 behind openings 42. To until the cross pin 32 at the other end of the release of the operating handle 22 closes the Slit opening 33 of the spindle wall strikes the check valve 38. and the Kotben leads as a result (Fig. I). a back expansion into the displacement 37 a small one

The displacement 37 of the Kotbens 31 is made by a return movement. wherein the lockable after the back check valve, the check valve located at the execution 45 spaces 43, 28, 26 entrungsbeispiel is not formed by a ball 38 which are utilized, because the openings 42 in ö ~ r spindle -through a spring 39 to a Paragraph of the Spindclboh- wall between the two sealing rings 40 and 30 is pressed. ⁴ I of the piston 31 remain.

In one end section, the piston 31 has two

axially spaced from one another is moved out in the opening direction, so leads processing rings 40 and 41. see the stop of the pin, which is terminated by the one near the free piston 32 at the end of the slot 33. In this case of the sealing ring 40 located in the piston stroke forward movement of the piston 31 overflows which are overflowed. The second sealing ring 41 55 sealing ring 40 seals the openings 42 of the spindle wall in the closed position (FIG. 1) behind the. The result is that the under the Dichtungsman openings 42 from the outside. The space 43 rächschetteö compressed mixture through the opening check valve 38 is through openings 44 in gene 42 in the piston displacement 37 can relax the wall of the spindle bore with the annular gap 28 and the sealing sleeve is relieved. The connected. * ° Sealing sleeve 6 no longer presses against it

In the axial operating mode shown in FIG. 2, the housing wall and the spindle can be easily moved ment of the spindle 4 are the two inflow openings 2 push and twist. In the meantime that too and 3 completely exposed. The conical coupling member 34 with c η lugs 36 lies opposite them via the front spindle section 10. The flow area of the spindle 4 is locked back is the greatest here. As a result of the asymmetrical 65 piston 31 and the spindle 4 again for moving The conical surface of the spindle section 10 is coupled to one another by 180 ° in the closing direction.
