first organs only transfer that to the first valve when the manifold and the valve housing are connected to each other * so that the first valve can only be activated by moving the first organ can be opened when the distribution line is connected to the valve housing and in its operating position attached to it

Further details and advantages of the invention result from the following description of an embodiment 3 with reference to the drawing.

The drawing iat a longitudinal section through an inventive Valve arrangement,

In the drawing, the valve assembly includes a valve housing t »it a first Kaanaer 2 · The chamber 2 has a first inlet 3 and a first outlet 4 aufj the outlet 4 is normally among -ß'ed he voltage standing · first valve member 5 f eschloseen held. The outlet 4 is connected to a burner distributor T2 via a channel 6. May be the fuel, * · Β · Jfaptha can the burner manifold 12 via a fuel line, not shown here are supplied to the "ith the inlet 3 connected · The supply of fuel to the burner manifold 12 can divide by '' ere of Valve 5 can be controlled

So that the 7-valve organ 5 can be moved, praise a first movable organ or. a rod 7 is provided which has a 3ewlndeabaohnitt 7a? the rod or spindle 7 can be moved in the axial direction within the valve housing 1, with the aid of a fixed at the free end of the spindle

Hand wheel 8; the (rewinding section 7a of the valve spindle is working together with a threaded hole in a plate 9, the τοη with the valve housing 1 connected column parts 10 is carried. The burner manifold 12 carries a flexible membrane 11 ale Support for a second movable member or a Bolaen 13, so that when the burner manifold 12 with the Valve housing 1 is connected, the bolt 13 between the free end of the valve spindle 7 and the adjacent end of the valve members 5 lies. Mur when the bolt 13 is in this position, causes an axial movement of the valve spindle, the according to the drawing to the right that the valve member 5 is moved against the associated i'eder 5a to the outlet 4 to open; This «opening position is shown in the drawing; it can thus be seen that the bolt 13 serves to transmit the movement of the valve spindle 7 to the valve member 5.

The means for connecting the burner manifold 12 to the valve housing 1 comprise a toggle-operated clamping device with an actuating arm H which has an opening 14a through which the free end of the valve spindle can move, when the arm 14 is in its locked position and the valve spindle holds the valve member 5 lifted from its seat 12 can be dismantled when valve 5 has been closed. This ensures that the fuel supply must be interrupted before the valve housing is removed from the burner manifold is separated.

The ^v entilepindel 7 transmits a "wide valve member 7b whose Durchaeeeer is greater than the diameter of the valve stem; This valve organ is' wiping the ends of the

Valve spindle provided and in a second chamber 15 aas Valve housing 1 arranged · The second chamber 15 has a second inlet 16, through which steam "" is passed, and it there is a second outlet 17 and a third outlet 18. The outlet 17 is in the valve housing 1 via a channel 19 Connection to the outlet 4 leading to the valve chamber 2 and can be closed by an axial movement of the second valve member 7a of the valve spindle, which according to the drawing to the right takes place. The closing of the wide outlet 17 takes place at the same time as opening the valve 5, when that Valve housing and the burner manifold in their position of use are connected to each other "

The third outlet 18, which adjoins the second chamber 15 ″, is opened by an independent third valve element 20 controlled, which can be operated with the help of a% ndradea 21 can · The outlet 16 is connected to the burner distributor 12 via a channel 22 bit ·

During operation, the valve housing 1 and the Branner distributor 12 assume the position shown in the drawing, d * fr. the valve 5 is open, ao that the fuel dam Brannar-Vertella? is led through the inlet 3, slide ₉ Kammer2 the outlet 4, and d "n channel. 6 Steam is used to atomize the fuel, and the burner distributor can be fed through inlet 16, chamber 15, outlet 18 and channel 22 when valve 20 is open.

When it is necessary to separate the valve housing 1 from the burner manifold 12, the valve spindle 7 is moved axially to the left as shown in the drawing. At the initial axial

Movement of the valve spindle can close the first valve 5 under the influence of its element 5a, so that the supply of fuel to the burners is interrupted Inlet 16 can flow from through the channel 19 sun burner manifold. When the valve stem 7 maintains the initial position, the steam removes all of the reed fuel from the burner manifold, and this fuel is blown by the steam into the furnace where it is burned.

With a further axial movement of the valve spindle 7 to the left, the free end of the valve spindle is pulled out of the opening 14a of the arm 14, and it is caused that the sweite valve member 7b closes the inlet 16 to the chamber 15, so that the supply of dump is interrupted "Now the valve 20 is closed and the valve housing 1 can be removed from the burner distributor, because the toggle lever 14 can now be moved unhindered."

It can thus be seen that with the valve arrangement described it is necessary to interrupt the supply of fuel to the burner distributor and to blow out the burner distributor in order to remove the fuel residues before it is possible to separate the valve housing from the burner distributor. In this way, there is no risk of fuel leaking out of the burner distributor or the valve housing, which would be possible if • in
