Der Gegenstand der Erfindung betrifft eine Ventilsteuerung, bei welcher die Kraft des Steuerungsgestänges (hier Zug) dem Ventilhebel h durch eine Feder f übermittelt wird. Dieselbe ist so gewählt bezw. durch die Regulirschraube r eingestellt, dafs im zusammengedrückten Zustand, d. h. wenn oder kurz bevor sich die zwei Stahlplatten JJ1P2 berühren, ihre Spannung 0- mit dem betreffenden Arm des Ventilhebels h ein Moment M0. ergiebt, welches in Bezug auf das durch die Ventilfeder ν zusammen mit der zur Beschleunigung der Ventilmassen nöthigen Kraft und dem anderen Arm des Ventilhebels h erfolgende Moment Mv ergeben mufsThe subject matter of the invention relates to a valve control in which the force of the control linkage (here train) is transmitted to the valve lever h by a spring f. The same is chosen respectively. adjusted by the regulating screw r , that in the compressed state, ie when or shortly before the two steel plates JJ 1 P 2 touch, their tension 0 with the relevant arm of the valve lever h is a moment M 0 . it follows that with respect to the ν by the valve spring together with the valve to accelerate the masses requisite force and the other arm of the valve lever taking place moment M h v give PUFA
M, 5 Mv, M, 5 M v ,
und zwar M0. > Mv, wenn höchstmögliche .,Geräuschlosigkeit beim Arbeiten der Steuerung angestrebt wird.namely M 0 . > M v , if the highest possible., Noiselessness is aimed for when working with the control.
Durch diese Eigenschaft der Feder f wird dem Ventilhebel h ein Moment eingeleitet, das allmählich von ungefähr ο bis M0. wächst. Hierdurch wird ermöglicht, ohne Bruchgefahr für die Steuerungstheile: 1. das Ventil nach Ueberwindung des auf demselben lastenden Dampfdruckes plötzlich, also mit einer Drosselung = o, anzuheben und mit voller Geschwindigkeit wieder aufzusetzen, 2. eine gröfsere minutliche Umlaufszahl.As a result of this property of the spring f , a moment is introduced into the valve lever h that gradually increases from approximately ο to M 0 . grows. This makes it possible, without the risk of breakage for the control parts: 1. after overcoming the steam pressure on the same, suddenly to raise the valve, i.e. with a throttling = 0, and to put it back on at full speed, 2. a larger number of minutes per minute.
