Since the outlet valve shown in Pig »2 is made up of a multitude consists of individual parts that require separate manufacture and assembly, it is comparatively expensive and according to another feature of the invention is a modified form of an outlet valve conceivable, the cheaper and is shown in FIGS. 6 and 7

The principle of construction used here consists in successive elements or "layers" of the spout valve body to pour on top of each other. The supply pipe 1 can be a conventional LIe ssinrr pipe (although just as well a plastic pipe can be used), and its upper end is provided with a surface which (similar to the opening 14 and its surroundings according to FIG. 2) as a seat can serve for a sealing disk of the outlet valve. A cylindrical inner body 19 made of suitable plastic, e.g. B. glass-filled nylon, cast with a side outlet »The pipe 1 can be provided with an external thread, but over a length of 20 the pipe is unthreaded and knurled to wedge the inner body against rotation. At the height of its inner end is the inner body 19 with a step 21 and a little further up provided with a rib 22. The upper end of this rib 22 is internally threaded around the spout valve operating mechanism (as described with reference to shoulder 4 in Fig. 2).

A subsequent casting process becomes an external one The outlet valve body is cast onto the assembly consisting of the supply pipe and the inner body. The-

this outer body consists of an inner sleeve 23, which is rigidly connected to the inner body via the step 21 and the rib 22 and with an outer jacket-like Body is made from one piece, which with. the lower cylinder 3> the upper conical shoulder 4 and the laterally protruding mouthpiece 5 formed is, which is with the side outlet of the inner body 19 in Überdeokung, and its external appearance is substantially is similar to that shown in Figs. The outer jacket-like body can be made of suitable thermoplastic Material to be made. It can be used because the inner nylon body makes it different from acetal Brass pipe separates and prevents dezincification of the brass. A preferred material for the outer body if it is to be chrome plated is A.B.S., and there that Outlet valve is closed at the upper end of the brass tube 1, this body is suitable for use with hot water, which as a result of the brass tube 1 of the Plastic body is kept away and does not weaken it.

A mold for casting a spout valve body like him in Pig. 6 is shown in FIG. A lower mold half 24 takes the supply pipe 1 with a inner body 19 pre-cast thereon in a solid core 26 with an upwardly protruding cylinder on, which surrounds the inner body 19 but is at a distance from it to provide a casting space for the to create inner sleeve 23 of the outer body. The upper mold half 25 is cut out so that it surrounds the inner body 19 forms a shell which forms the casting space for the outer parts 3 and 4 of the outlet valve body

limited. Another solid core 27 in the lower mold half 24 protrudes upward into an extension of the recess into the upper half of the mold and works with it to create the casting space for the one with the parts 3 and 4 firmly connected Absohnitt of the mouthpiece 5 to limit. An L-shaped shaped section 28 is by means of one leg releasably inserted into a bore of the core 27, and another leg extends up to a preformed side hole in the interior Body 19 and through it to keep a fluid channel open through the inner end of the mouthpiece 5, when it's poured.

When the parts of the mold are assembled in the arrangement shown in Fig. 8, the plastic forms the finished outlet valve body in the unshaded areas of the figure bounded by the cores and mold sections. When the top half of the mold is then lifted off is, the outlet valve body and the supply pipe 1 together with the mold section 28 from the lower Mold half 24 lifted out. The mold section 28 can then be moved in a direction parallel to the axis of the in of the mouthpiece bore embedded leg (i.e. to the right according to FIG. 8) into a position in which it can be removed from the lower canal length of the mouthpiece downwards. The outlet valve body will then by securing a separately cast plate 15, 16 as described above under the outer one channel-shaped end of the mouthpiece completed.

In another construction according to the invention, as set out in Pig. 14 to 17 is a spout valve body made by casting a substantially cylindrical body 50 with an integral, radially protruding outlet pipe or mouthpiece 5I made of suitable plastic. The outer end of the outlet pipe 51 is open and has a short end 52 with a reduced outer diameter. The tube 51 can be substantially rectangular have inner cross-section.

A separately cast element consists of an I-shaped tube 53 with a shoulder part (Fig. 15), which is attached to a End has an internal cross-section which corresponds to that of the tube 51 (see Pig. 17) »and that with a Step 54 is provided which fits on the end 52 of the tube 51 of reduced outer diameter. On the other end it runs out into a conventional round outlet opening 55. The tube 53 is attached to the end 52 of the tube 51 and secured thereto by suitable means, e.g. B. by means of Glue or by welding.

The combined unit consisting of the cylindrical body 50, the pipe 51 and the pipe 53 is then used as a core to make an outer layer 56 from the outside Apply plastic or other material (e.g. by casting).

As described above, the body can act on one Tube 1 can be poured on, and the whole thing can be outside with Metal to be plated. The inner body, the outlet pipe and the pipe with the shoulder portion can expediently made of glass-filled, hydrolysis resistant

The drain valve can be similar in shape of those described above with reference to FIG. 8, and all of the features mentioned above can be made used in the manufacture of the outlet valve body and in the design of the outlet valve itself will. -

In accordance with yet another feature of the invention, a drain valve for water and other liquids is suitable for remote control. The control mechanism is of such a form as shown in Figs. 9 and 10 and comprises an internally toothed external gear 29 which cooperates with an internal gear 30 to rotate a worm 31 which cooperates with a rack, whereby a spindle is moved longitudinally to open and close the drain valve. A spill valve mechanism of this type is described in U.K. Pat. No. 687,558. For remote actuation of such a drain valve, the outer gear 29 is also provided with external teeth 32 which mesh with a worm or rack 33 housed in a transverse cylindrical housing 34 which is attached or fixed to the body 35 of the drain valve 'is molded.
