Description

GERMAN

The invention relates to a new, advantageous embodiment of an upper valve part with a non-rising Spindle, which together with a profile rubber ring arranged in an annular groove of the spindle in the Valve upper part is stored.

Among other things, the spindle is installed in known designs by inserting it into the Upper part of the valve from above until a spindle collar hits a lower shoulder of the upper part bore and subsequent definition or protection against axial displacement visible at the top with a the upper valve part screwed on cap or nut or a fixed by a nut, in a Milling of the spindle engaging blanking disk or the like.

In contrast, the invention consists in that the spindle in the inserted position by an invisible inside the upper part arranged lock is set, which is preferably ring-shaped, d. H. as a one-part or multi-part ring, from the upper part of the valve in a corresponding annular groove of the spindle to Snaps into place. The locking of the ring can take place automatically, for. B. through training as resilient snap ring. But it can also be done by hand, ζ. B. by means of radially or tangentially acting screws be feasible.

The embodiment according to the invention has the advantage that the upper part head is free of any fasteners, screws, washers, etc. So the handle can, apart from the simplification of the construction, can be pulled down to the head of the valve upper part, whereby an Construction height is gained and transitions that are excellent in terms of taste and hygiene are created can.

Figs. 1 and 2 each illustrate the invention in an example of an insertable by screwing and an automatically acting lock, wherein the handle with the spindle advantageously as a one-piece Assembly unit is executed. (All metal or metal spindle with cementing, spraying, Screws, etc. attached porcelain, plastic or similar handle.) This is in the images In each case 1 the upper part housing, 2 the handle with the spindle 4 carrying the rubber profile sealing ring 3, 5 the closure piece with seal 6.

In Fig. 1, 7 is the lock designed as a two-part ring. After inserting it from below into the The screw hole 8 of the upper part housing becomes the ring by screwing in the guides 9 for the closure piece bearing screw sleeve 10, which carries a conical shoulder 11, so narrowed that it is in the The ring groove 12 of the spindle engages, with the result that the spindle is axially fixed on both sides.

In Fig. 2, a lock is used below the seal guide in an annular groove 14 in the upper part housing 1 arranged spring snap ring 13th diameter and incision width are dimensioned with him so that he. in the relaxed state into the bore of the upper part housing without the guide in the annular groove 14 to lose. The spindle has a corresponding annular groove 15 into which the snap ring at Pushing in the spindle engages and thus axially fixes the spindle on both sides. By arrangement of conical surfaces 16 on the snap ring, 17 on the spindle collar and 18 on the head of the upper part bore This makes it easier to insert the snap ring and to press the spindle through until it clicks into place. Of course, in this special embodiment, the spindle can be replaced at a later date not possible anymore.

After the concept of the invention has been disclosed, the most diverse are so for the relevant person skilled in the art Versions of the invisible locking of the spindle in the upper part of the valve are possible.

Claims (7)

PATENT CLAIM: 1. Upper valve part with non-rising spindle, which together with one in an annular groove of the Spindle arranged profile rubber sealing ring is mounted in the valve upper part, characterized in that that the axial fixing of the spindle by means of a located in the interior of the upper valve part (1), preferably annular lock takes place, which is brought into engagement with the spindle either by hand or automatically when the valve is assembled will. 2. Upper valve part according to claim 1, characterized in that the lock below the ring 909 728/302 groove for the rubber sealing ring is arranged in the spindle. 3. Upper valve part according to claim 1 and 2, characterized in that the lock is one in one The ring groove in the interior of the upper part of the valve is a split ring (7) which, by radial force, is so is narrowed so that it engages in an annular groove (12) of the spindle. 4. Upper valve part according to claim 1 to 3, characterized in that the radial force for Narrowing of the ring (7) preferably by a screw to be screwed into the upper valve part (1) from below Screw sleeve (10) is exercised, which for this purpose has a corresponding conical shoulder (11) carries and at the same time contains the guides (9) for the closure piece (5). 5. Upper valve part according to claim 1 and 2, characterized in that the lock is a inside the valve upper part is the annular groove (14) inserted snap ring (13), weleher engages resiliently in a spindle ring groove (15) when the spindle is pushed in. 6. Upper valve part according to claim 1 and 2 and 5, characterized in that the upper end of the bore in the upper valve part, the snap ring (13) and the spindle collar which comes into contact first with the snap ring during assembly, facilitating the insertion of the snap ring and the spindle { 18, 16., 17) wear. 7. Upper valve part according to claim 1 to 6, characterized in that the handle (2) and Spindle (4) form a one-piece assembly unit, the lower annular end face of the handle and the upper circular face of the upper valve part have the same outer diameter to have.
