The invention relates to a reusable faucet for meowing or distribution of liquids in heating and air conditioning systems or the like, with inlet and outlet openings having cock chamber in which a rotatable Chick is arranged, on both sides of which each a Durohflussraum is »where is in the circumferential wall the tap chamber is located at least errfenkammer opening through an opposite end face of the chick depending on the angular position of the chick in two oppositely adjustable Durohläsee can be subdivided »the different Durohflussverbindungen are assigned, with one passage closed in one position of the plug and in one in the other position of the plug the other passage is blocked and in the intermediate positions of the plug the both passages depending on the position of the chick are open to different degrees.

A preferred field of application of such free-way taps are heating systems, and they are used here for this purpose , hot boiler feed water with cooler heating water to mix with heating flow water. The temperature of the heating flow water can here can be adjusted by turning the chick. In some In some cases, such multi-way taps can also be used as distributor taps. Especially in heating systems the liquids flowing into the tap chamber generally have considerably different temperatures on, creating a consistent seal of the

both flow spaces are made more difficult against each other, special then if the cock housing and the chick made of materials with different coefficients of thermal expansion insist · The waterproofing is also enhanced by this made difficult by the fits and tolerances of the chick must be hit in the Bahnkanmer so that the The chick always moves easily · rotates and does not tend to jam systems the water to be mixed or distributed is mostly dirty and also has a strong corrosive effect, which means the designer is considerably restricted in the choice of materials that are easy to process and cheaper. · Also This is usually the case with such free-path taps about mass-produced articles for which there is fierce competition, so that special emphasis must be placed on simple and inexpensive production options. Despite these difficulties, in practice the indispensable requirement that in all operating conditions the plug can always be turned slightly and the two flow spaces are well sealed against each other, so that Xempera ^ urfälsohungen through leakage losses " the liquid or liquids escaping from the mixer tap.

A good seal between the two flow spaces is particularly important with reusable taps of the type mentioned, in which at least one end face of the chick on one side or one

of the type mentioned initially provided according to the invention, that the chick two adjacent to the circumference of the cock chamber Has forehead parts that relate to the Kükendrehaohse radially displaceable on one around the rotary plug rotatably mounted plug middle part arranged

and duroh elastic loading means or the like in directions leading away from the plug rotation axis are pressed against the circumferential wall of the cock canister, 'and that farrier the plug has one of the end faces of the cock chamber λ at a distance opposite first end surface, which with the opposite circumferential wall of the cock chamber to mutual sealing of the two flow spaces interacts.

The invention is based on the aforementioned measure based on the consideration that the chick can be rotated on loan in all operating conditions that occur, an sloh must have both a certain radial play and an axial play · This double play would however »if no special measures are taken, in practice lead to considerable corner losses. Duroh the invention avoids this deficiency in a simple and secure ™ manner.

In some cases it can be sufficient if the first Endoheibe is integrally formed and to a tight fit between it and the Hahnkammergenause make it possible to use a material of approximately the same temperature

expansion coefficients like the neighboring Hahnkamiaerwandung consists «Here can be used for the first end of the year Due to the relatively low material requirement, high quality material can be used and / or it can be used with suitable, corrosion-insensitive coatings are provided, which may also have good sliding properties * It is better, however, if such an end « soheibe has at least one circumferential groove into which a Sealing ring or the like is inserted, so that between her and the valve chamber, if necessary, even there may be considerable play, which is compensated for by the sealing ring »

The sealing of the two thermosetting flow spaces against each other on the side of the plug opposite to the first end disk generally does not cause any particular difficulties. so that the plug is constantly pressed against the other end face of the cock chamber.In the simplest case, the plug middle part and the plug end parts can be in close contact with the named end face of the cock chamber the other end face of the cock chamber has a second end plate opposite to each other, which serves to seal the two Durohflusaräume in their area against each other. These

Avoidance of the EU, can be provided for two purposes " that the individual chick part calibrates over a central angle which is at least half the central angle corresponds to the associated valve chamber opening.

In a preferred further development it is provided that with at least one chick's forehead part its the size the front side edges, which co-determine its two seldom high passages, have a different course in relation to the liquid or distribution ratio of the currents flowing through these passages to influence in desired catfish. In this way, for example, when using the multi-way tap as a mixing tap in pickling plants, a linearization of the characteristic curve of the pickling flow temperature In can be known per se Catfish are achieved «·

The multi-way tap according to the invention can be used with advantage Be designed as a three-way cock or four-way cock. Formation as a three-way cock works in a known way only one of the two plug face parts with a cock chamber opening to divide it into two passages « When designed as a four-way cock, on the other hand, both plug front parts with associated rail chamber openings act to their Subdivision into two passages together.

The individual passage can optionally through the respective chick face in two or more on top of each other arranged partial openings be divided. In general, however, it is more advantageous if the individual
