ürems air shut-off valve

Brake air shut-off valves are used, especially for railway vehicles, used in two symmetrical designs, as a left model and a kechts model from each other below rope irdon with the venting head pointing upwards, looking in the direction of the eye on the end of the spinning belt connected to the operating lever, is the connection for the IJreinskupp] uii ;; sschlnuch in the left model left and the pipe connection for the main air ti ei do ·. on the right, on the pike model, the connection for the uremskupplurirsschlnuch on the right and the pipe connection for the main air on the left.

For the previous left and right models these taps are two different, mutually symmetrical valve bodies required both for taps for conventional, manually operated vehicle clutches as well as for taps for automatic central buffer couplings, and for taps both for the conventional al / -ua-ii Can be used for central buffer couplings.

For the taps for conventional couplings with coupling hooks,

Coupling bracket and tensioning device is the tap connection for the

for example /

Brex coupling hose inclined downwards by / 35, and the operating lever is a handle. The connections for the brake clutch hose are located on the taps for automatic central buffer couplings and for the main air line in alignment, and the operating lever is a forked lever that connects to the automatic clutch is operated. The ones for both conventional and Central buffer couplings have taps that can be used between the tap

for example /

housing and the pipe connection for the main air line at / 17.5 ^V to the vertical.

The invention is based on the object for links and Rnr-hUimoiolle to use the same housing and otherwise the same components, so that either a left or a right model can be assembled from the same components, and a left model into a Right model or vice versa, a right model can be converted into a left model in a simple manner.

BAD ORIQtNAL

This is done in the case of the Bremsluftabaperrhrihn il.-uliuvh according to the invention achieves that one spindle end is mounted on the inside of a first housing cover, the other spindle end by a second Housing cover passed through airtight and outside with the actuating lever is provided, and that the two housing covers while maintaining their assignment to the spindle ends on the tap housing with each other are interchangeable.

This cock is, depending on which side of the housing the first or the second cover was mounted, a left or a Legal model. By using the same housing for both models, the manufacturing costs are reduced, the inventory of the Individual parts are simplified, and if, for example, a left model is available but a right model is required, the Left model only partially dismantled and with interchanged covers (and accordingly swapped spindle ends) to be reassembled, whereupon a right-hand model is available instead of the left-hand model stands. Accordingly, if a right model is available, a left model can be obtained.

In the following, an embodiment of the subject matter of the invention described in more detail using the accompanying drawing. Show it:

The brake air shut-off valve shown has a substantially

cylindrical valve body 1, which has a connecting piece 2 for the

for brake clutch hose, one extension 3 / one vent plug 37

and a connector flash 4 for one with a corresponding flange

5 provided pipe connection piece 6 for the main air line. The axes of the nozzle 2 and 6 and the extension 3 run perpendicular to the cylinder axis of the housing 1, the axes of the approach

3 and the flange 4 run at right angles to one another, the flanges

4 and 5 are to the aligned axes of the nozzle 2 and

6 inclined to the right by 12.5 ° to the vertical (Fig. 1 and 3). the Flanges 4 and 5 are connected to one another by screws 7.

709838/0690

The substantially cylindrical housing 1 is on both Front ends closed by housing cover (cylinder cover) 8 and 9c · - ·· ;, each of which has an Aisn-.n sitting in one end of the cylinder space 10 or 11 and a flange 12 or 13 resting against the cylinder edge (Fig. 2). Between the approach 10 or 11 and the flange 12 and 13, a sealing ring 14 is arranged. The covers 8 and 9 are fastened to the housing 1 by screws 15. In addition, these are Housing 1 and covers 8, 9 are provided with eyes 16 and 17, respectively. The covers 8 and 9 can be interchanged on the housing 1.

The tap spindle is arranged in the cylinder axis of the housing 1. One spindle end 18 is mounted on the inside of the housing cover 8, the other spindle end 19 is airtight through the other Cover 9 passed through and provided on the outside with a square 20 on which a forked actuating lever 21a (Fig. 1) for central buffer coupling or tap handle 21b (Fig. 6) for manually operated conventional coupling is releasably attached. The spindle 18, 19 is against axial Movement secured in the housing 1, as can be seen from FIG.

The locking piece 22 of the tap, which is firmly connected to the spindle 18, 19, has the shape of a spherical cap, which is shown in the figures 2, 3 and 5 shown ventilation position of the spindle the opening of a seat ring 23 mounted in the face 4, and in a 90 ° around the Spindelachee offset the passage position the opening of one of the

709838/0690

BATH ORIGINAL Ventilation head 3 associated seat ring 24 closes.

A part 25 formed in one piece with the closure piece 22 (Figs. 2 and 5) has two near the inner surface of the housing cover 9 radial bores offset by 90 to the spindle axis 26 and 27. A pin 28 is detachably seated in the bore 26 and is in the illustrated venting position of the valve on a fixed one Stop 29 and after turning the locking piece into the through position at a fixed stop 30. The stops 29 and 30 are formed on the inside of the cover 9.

Venn the cock shown, the - as mentioned - a left model is, by swapping the housing covers 8 and 9 in a right model is converted, as described further inten, the pin 28 is det Bore 26 pulled out and inserted into bore 27. The distance of the outer end of the pin 28 from the cylindrical inner surface 31 of the housing 1 is shorter than the length section of the pin 28 seated in part 25, so that the pin 28 does not extend the bore 26 or 27 can solve and always reliably cooperates with the stops 29 and 30.

A latching device is provided on the inside of the cover 8 and on the spindle end 18; This consists of two leaf spring sets 32, the one hand on the inner projections 33 of the pool 8 and other

are supported on a square 34 firmly seated on the spindle end 18 (Pig. 2 and 3) So that the leaf spring sets 32 remain held on the cover 8 even when the spindle for interchanging the covers 8 and 9 from its bearing 35 (Pig · 2) is pulled out on the cover 8, whereupon the spring sets 32 can no longer be supported on the square 34, additional projections 36 (Pig. 3) are provided on the inside of the cover 8 opposite the projections 33. The projections 33 and 36 are beveled or. rounded to allow the leaf spring sets 32 a simple curvature when the square 34 is rotated.

Notwithstanding the illustrated embodiment, the stops and the latching device can also be on one and the same housing cover to be ordered.

In order to convert the left-hand model of the cock into a right-hand model, with the operating lever in the view of the Pig. I and 6 is to be converted not in front of but behind the tap housing, the covers 8 and 9 are to be exchanged with one another in the bit ventilation position shown, the spindle end 19 remaining in the cover 9, the spindle end 18 being reinserted into its bearing 35 on the cover 8, to move the actuating lever 21a on the square 20 by 90 ° and to move the pin 28 from the bore 26 into the bore 27.

Of course, a right-hand model can also be put together from the outset from the parts of the cock described, and such a model can also be converted into a left-hand model.

709838/0690

To the cock described in connection with FIGS. 1 to 5, the is assembled for use with automatic central buffer couplings, to be used for conventional, hand-operated couplings, the flanges 4 and 5 are detached from each other, the flange 5 is rotated together with the nozzle 6 by 180 about its axis and then screwed back to the flange 4. Thereupon the connection 2 for the brake clutch hose is directed obliquely downwards, like required for manually operated clutches. The forked operating lever 21a is replaced by the tap handle 21b. Of course, the cock can also be used from the outset from the parts described Can be assembled using hand-operated couplings.
