PATENTAMT.PATENT OFFICE.
Die Construction hat den Zweck, den Maximaldurchflufsquerschnitt eines Ventils jederzeit beliebig verkleinern zu können, dergestalt, dafs auch der verkleinerte Maximalquerschnitt erst beim vollen, sich stets gleichbleibenden Hub des Ventils erreicht wird.The purpose of the construction is to maintain the maximum flow area of a valve at any time to be able to reduce at will, in such a way that also the reduced maximum cross-section is only reached with the full, always constant stroke of the valve.
Es wird dies durch den Ventilkegel ν in Verbindung mit dem Regulirkolben k bewirkt, deren Spindeln mit entgegengesetzten Gewinden (die eine mit Rechts-, die andere mit Linksgewinde) versehen sind. ·This is brought about by the valve cone ν in connection with the regulating piston k , the spindles of which are provided with opposing threads (one with a right-hand thread, the other with a left-hand thread). ·
Der Regulirkolben k greift mit seiner oberen Verlängerung in die. hohle Spindel von ν derart ein, dafs er sich in axialer Richtung verschieben, aber nicht in der Spindel verdrehen kann, so dafs also beim Drehen von ν auch der Kolben k in gleichem Sinne gedreht wird, wegen der entgegengesetzten Gewinde aber in axialer Richtung die entgegengesetzte Bewegung von ν macht. Geht ν nach oben, sß geht gleichzeitig k nach unten. In seiner höchsten Stellung befindet sich k ganz innerhalb des Ventilsitzes s und füllt den Querschnitt desselben vollständig aus, da sein gröfster Durchmesser gleich demjenigen von s ist.The regulating piston k engages with its upper extension in the. hollow spindle of ν in such a way that it can move in the axial direction but cannot turn in the spindle, so that when turning ν the piston k is turned in the same direction, but because of the opposite thread the opposite one in the axial direction Makes movement of ν. If ν goes up, sß goes down at the same time k . In its highest position, k is completely inside the valve seat s and completely fills the cross section of the same, since its largest diameter is equal to that of s .
Zum Einstellen beliebiger Maximaldurchflufsquerschnitte ist das Muttergewinde von ν in dem Bügel r des Ventilgehäuses drehbar gelagert und durch die Schrauben t gegen r festgelegt; Löst man die Schrauben t, so kann man ν gleichzeitig mit seiner Mutter drehen, ohne dafs sich ν in axialer Richtung verschiebt, während der die Drehung mitmachende Kolben k seinen Abstand von ν und damit seine Lage zum Ventilsitz s ändert.To set any maximum flow cross-section, the nut thread of ν is rotatably mounted in the bracket r of the valve housing and is fixed against r by the screws t; Solving t the screws, one can ν simultaneously with its mother rotate without DAF ν in the axial direction moves, while the rotation mitmach pistons k ν its distance from and its position relative to valve seat S changes.
