Das auf der Zeichnung dargestellte Ein- und Auslafsventil unterscheidet sich dadurch von dem im Haupt-Patente Nr. 63533 beschriebenen, dafs an Stelle eines an der biegsamen Platte befestigten Ventils hier ein von der Platte unabhängig selbstthätig wirkendes Ventil angeordnet· ist. Die biegsame Platte wird nicht unmittelbar durch die Niederschraubspindel, sondern unter Zwischenschaltung der die biegsame Platte belastenden Federn niedergedrückt. Das mit der nach oben gerichteten Ventilstange al ausgerüstete Ventil α wird durch die Feder/ nach oben gegen seinen Sitz geprefst. Oberhalb dieses Ventils α ist das mit der Ventilstange r1 versehene Ventil r angeordnet, das durch die Feder t ebenfalls nach oben gegen seinen Sitz gehalten wird. Der Stutzen d wird mit dem Behälter für die Druckflüssigkeit oder das Gas verbunden.The inlet and outlet valve shown in the drawing differs from the one described in the main patent no. 63533 in that, instead of a valve attached to the flexible plate, a valve that operates independently of the plate is arranged here. The flexible plate is not pressed down directly by the screw-down spindle, but with the interposition of the springs loading the flexible plate. The valve α equipped with the upwardly directed valve rod a l is pressed upwards against its seat by the spring /. Above this valve α , the valve r provided with the valve rod r 1 is arranged, which is also held up against its seat by the spring t. The nozzle d is connected to the container for the pressure fluid or the gas.

Beim Einlassen durch den Stutzen c drückt die Druckflüssigkeit das Ventil α nach unten und öffnet sich dadurch den Weg nach dem Druckbehälter, in den sie in der Richtung der Pfeile 2-2 einströmt. Gleichzeitig wird das durch die Feder t schon nach oben gehaltene Ventil r durch die Druckflüssigkeit fest gegen seinen Sitz geprefst. Dadurch wird das Eintreten der Druckflüssigkeit in den Raum unter die biegsame Platte i und eine Beschädigung dieser Platte verhindert. .When it is let in through the nozzle c , the pressure fluid presses the valve α downwards and thereby opens the path to the pressure vessel, into which it flows in the direction of the arrows 2-2. At the same time, the valve r , which is already held up by the spring t, is pressed firmly against its seat by the hydraulic fluid. This prevents the pressure fluid from entering the space under the flexible plate i and damaging this plate. .

Sobald der Druck der einströmenden Flüssigkeit aufhört, wird das Ventil α wieder geschlossen. As soon as the pressure of the inflowing liquid ceases, the valve α is closed again.

Beim Auslassen mufs die Druckflüssigkeit den umgekehrten Weg in der Richtung der Pfeile 1 nehmen. Da aber in diesem Falle die Druckflüssigkeit bestrebt ist, das Ventil α zu schliefsen, so mufs dieses Ventil geöffnet werden. Zu diesem Zweck wird die mit dem Handrad s1 versehene Druckspindel s niedergeschraubt und hierbei die Scheibe χ niedergedrückt. Dadurch werden die Federn h h zusammengeprefst und die biegsame Platte i durch die Platte y nach unten gedrückt. Die biegsame Platte überträgt den Druck auf die Ventilstange r1, die behufs Verhinderung einer Beschädigung der Platte i eine Metallscheibe r2 trägt. Das Ventil. r drückt weiter die Ventilstange a1 nach unten und öffnet dadurch das Ventil a. Nun strömt die Druckflüssigkeit in der Richtung der Pfeile 1 aus dem Druckbehälter und biegt dabei die Platte i so weit nach oben durch, bis der Druck der ausströmenden Flüssigkeit gleich dem Druck der die Platte i niederhaltenden Federn h h ist. Man hat es also ganz in der Hand, durch Verstellung der Spindel s die Federn h h so anzuspannen, dafs die Druckflüssigkeit mit geregeltem Druck ausströmt. Beim Ueberschreiten des eingestellten Druckes der ausströmendenWhen discharging, the hydraulic fluid must take the opposite path in the direction of the arrows 1. Since, however, in this case the pressure fluid tries to close the valve α , this valve must be opened. For this purpose the pressure spindle s provided with the handwheel s 1 is screwed down and the disk χ is pressed down. This compresses the springs hh and pushes the flexible plate i downwards through the plate y. The flexible plate transmits the pressure to the valve rod r 1 , which carries a metal disc r 2 to prevent damage to the plate i. The valve. r continues to push valve rod a 1 down, thereby opening valve a. Now the pressure fluid flows in the direction of the arrows 1 out of the pressure vessel and bends the plate i so far upwards until the pressure of the outflowing liquid is equal to the pressure of the springs hh holding down the plate i . It is entirely up to you to tighten the springs hh by adjusting the spindle s so that the hydraulic fluid flows out at a controlled pressure. When the set pressure is exceeded, the outflowing

Flüssigkeit wird die Platte i gehoben und infolge dessen das Ventil α durch die Feder f geschlossen. Beim Nachlassen dieses Druckes drücken die Federn h h die biegsame Platte wieder nieder und öffnen dadurch das Ventil a. Liquid, the plate i is lifted and as a result, the valve α is closed by the spring f. When this pressure is released, the springs hh press the flexible plate down again and thereby open the valve a.

Patent-Anspruch:Patent claim: Ein Ventil zum Ein- und Auslassen von unter Druck stehenden Gasen und Flüssigkeiten der durch Patent Nr. 63533 geschützten Art in der Weise abgeändert, dafs das Ventil (r) unterhalb der biegsamen Druckplatte von dieser getrennt ist und bei der Einströmung (Pfeile 2) durch den Druck des Gases oder der Flüssigkeit selbstthätig geschlossen wird behufs Fernhaltung des Druckes von der Druckplatte, während bei der Ausströmung (Pfeile 1) durch die mittels der Federn (h) eingestellte Belastung der biegsamen Platte (i) beide Ventile mittels der Ventilstangen (rl al) gemeinsam geöffnet oder geschlossen werden, je nach der den Druck regelnden Wirkung der auf den beiden Seiten der biegsamen Druckplatte angeordneten Federn (h tf). A valve for the inlet and outlet of pressurized gases and liquids of the type protected by patent no. 63533 modified in such a way that the valve (r) is separated from the flexible pressure plate below and upon the inflow (arrows 2) the pressure of the gas or liquid is automatically closed in order to keep the pressure away from the pressure plate, while during the outflow (arrows 1) due to the load on the flexible plate (i) set by means of the springs (h) , both valves are operated by means of the valve rods (r l a l ) are opened or closed together, depending on the pressure-regulating effect of the springs (h tf) arranged on the two sides of the flexible pressure plate.
