Vorrichtung zur Druckregelung in Brems-und Presszyiindern.
Beiden bisher zur Verwendung gelangenden Vorrichtungen zur Druckregelung in Broms-bezw.
Presszylindern unddergl., durch die der Druckindiesen Zylindern bis zu einem bestimmten Maximum je nach Auslage des Handhebels bezw. Betätigungsorganes beliebig verändert wird, besteht der übelstand, dass entweder ein zu grosser Verlust an Druckmittel (Dampf, Luft, Wasser ete,.) oder

mittelverlust den spezifischen Druck in einem Brems-bezw. Presszylinder oder dergl. je nach Auslage des Betätigungsorganes zu verändern und zwar bis zu einer Hohe, welche dem Drucke im Vorratsbehälter entspricht. Dazu wird ein entlasteter Kolbenschieber verwendet, bei dem das

Das Öffnen des Einströmkanals b erfolgt durch ein äusseres Betätigungsorgan z. B. mittels des Winkelhebels \ wobei der Kolbenschieber in der Pfeilrichtung I bewegt wird. Das Schliessen des Kanals b geschieht durch den Arbeitsdruck im Zylinder Z selbst, indem dieser Druck durch den Regelungskanal hindurch bis unter den Kolbenschieber K in den Raum e sich fortpflanzt und bewirkt, dass der Kolbenschieber in der Pfeilrichtung II bewegt wird. Bei dieser letzteren Bewegung (also in der Pfpilrichtung II) mu (3 durch den in dem Zylinder herrschenden Druck die Schraubenfeder'S zusammengedrückt werden. Je grösser also der Arbeitsdruck im Zylinder ist.

wird Kanal d durch die Schraubenfeder S wieder geschlossen.
Der auf die bchieberstange i von der Schraubenfeder S ausgeübte achsiale Stützdruck wird dadurch aufgenommen, dass der im Zylinder Z herrschende Arbeitsdruck auf die Fläche I

Device for regulating pressure in brake and press cylinders.
Two devices for pressure control in bromine and / or bromine that have been used so far.
Press cylinders and the like. By which the pressure in these cylinders up to a certain maximum depending on the position of the hand lever respectively. Actuator is changed at will, there is the problem that either too great a loss of pressure medium (steam, air, water, etc.) or

medium loss the specific pressure in a brake resp. Press cylinder or the like to change depending on the display of the actuator and up to a height that corresponds to the pressure in the storage container. A relieved piston valve is used for this, in which the
EMI1.2
The opening of the inflow channel b is carried out by an external actuator z. B. by means of the angle lever \ whereby the piston slide is moved in the direction of the arrow I. Channel b is closed by the working pressure in cylinder Z itself, in that this pressure propagates through the control channel to below piston valve K in space e and causes the piston valve to move in the direction of arrow II. During this latter movement (i.e. in arrow direction II) the helical spring'S must be compressed by the pressure prevailing in the cylinder. The greater the working pressure in the cylinder.
EMI1.3
channel d is closed again by the helical spring S.
The axial support pressure exerted on the slide rod i by the helical spring S is absorbed by the fact that the working pressure prevailing in the cylinder Z is applied to the surface I.
