 in der Zuleitung des Arbeitsdampfes oder der Arbeitsflüssigkeit zur Kraftmaschine D an. geordnet ist, so dass die Pumpe stehen bleibt. Ist die Pumpe elektrisch betrieben, so kann die Bewegung der Stange q auch auf einen Schalter behufs Abstellung der Maschine übertragen werden. 



   Sobald der Wasserstand und mithin der Druck sinkt, wird der Kolben p durch die Feder fl zurückgedrückt und das Absperrorgan V auf Offen gestellt. Die Maschine D beginnt wieder zu arbeiten und die Pumpe zu betätigen und es wird wieder Speisewasser in den Kessel gepresst. 



   Ist es in besonderen Fällen erforderlich, dass auch noch nach Erreichung des Normal-   wasserstandes   Speisowasser in den Kessel gedrückt werde, so wird eine in den Boden des Zylinders A mündende   Leitung'7-3   angeordnet. Durch Öffnung des in dieser Leitung beendlichen Absperrorganes a wird der Raum zwischen Kolben   L-und Zylinderboden   in offene Verbindung mit dem Kessel k gebracht, so dass ein Hinauspressen des Wassers aus dem Zylinder A bei Linksbewegung des Kolbens und daher eine weitere Förderung von Speise-   wnsser   durch das Ventil   d   und Leitung 12 erfolgt. 



   Die Leitung   1', 3 könnte auch   vom Boden des Zylinders A zum Rohre    führen,   wobei vor der   Mündung dos   letzteren in den Zylinder A ein Absperrorgan vorgesehen   sein muss, um   ein Nachströmen von Wasser in dem Zylinder A bei Speisung über den   Normalwasserstand   zu verhindern. 



   PATENT-ANSPRÜCHE : 
1. Vorrichtung zur automatischen Kesselspeisung, dadurch gekennzeichnet, dass bei   Erreichung   des Normalwassorstandes der   Zufluss   des Wassers aus der Druckleitung der

 in the supply line of the working steam or the working fluid to the engine D. is arranged so that the pump stops. If the pump is operated electrically, the movement of the rod q can also be transmitted to a switch for turning off the machine.



   As soon as the water level and consequently the pressure drops, the piston p is pushed back by the spring fl and the shut-off element V is set to open. The machine D begins to work again and to operate the pump and feed water is again pressed into the boiler.



   If it is necessary in special cases that feed water is pressed into the boiler even after the normal water level has been reached, a line 7-3 opening into the bottom of cylinder A is arranged. By opening the shut-off element a at the end of this line, the space between the piston L and the cylinder base is brought into open connection with the boiler k, so that the water is pressed out of the cylinder A when the piston moves to the left and therefore feed water continues to be conveyed takes place through the valve d and line 12.



   The line 1 ', 3 could also lead from the bottom of the cylinder A to the pipe, whereby a shut-off device must be provided in front of the opening of the latter in the cylinder A in order to prevent a flow of water in the cylinder A when it is fed above normal water level.



   PATENT CLAIMS:
1. A device for automatic boiler feed, characterized in that when the normal water level is reached, the inflow of water from the pressure line of the

Claims

2. Device for automatic boiler feed according to claim 1, characterized in that the water pressure rising when the access to the pressure valve is blocked when the feed pump continues to operate in the rooms and lines of the latter, a membrane. moves a piston or the like, overcoming its spring or weight load, and keeps the suction valve open from this membrane or the piston.

3. Device according to claims 1 and 2, characterized in that the sieve moving membrane, piston or the like. From the feed pump driving engine BEZW by shutting off the working steam or the working fluid. by EMI2.2 4. Apparatus according to claim 1, characterized by the arrangement of a lockable line (r3) leading to the boiler from the bottom dos cylinder (A), for the purpose of being able to continue the demand for feed water above normal water level. f *.

Device according to claim 1, characterized by the arrangement of a line starting from the testicle of the cylinder (and opening into the tube (r2) from the cylinder wall to the boiler, for the purpose of actuating a shut-off device arranged in the tube ('before its opening into the cylinder wall to be able to continue pumping feed water into the boiler above normal water level.
