Description

Gasdruckbremse Vielfach ist es für Gasdruckbremsen, insbesondere wenn solche, wie z. B. Notbremsen, nur selten in Gebrauch genommen werden, sehr unzweckmäßig, den den Bremsvorgang bewirkenden Druckunterschied vor und hinter dem Bremskolben durch verwickelte, einer Wartung und Beobachtung bedürfende mechanische Vorrichtungen zu bewirken. Ebenso unzweckmäßig ist es, diesen Druckunterschied durch vorrätige komprimierte Gase oder durch ein vorbereitetes Vakuum zu bewirken, denn beide können sehr leicht durch Undichtigkeiten ihre Wirkung verlieren und bedürfen daher einer ständigen Beobachtung.Gas pressure brakes It is often used for gas pressure brakes, especially when such as B. Emergency brakes, rarely used, very inexpedient, the pressure difference in front of and behind the brake piston causing the braking process by intricate mechanical devices requiring maintenance and observation to effect. It is just as inexpedient to have this pressure difference in stock to effect compressed gases or by a prepared vacuum, because both can very easily lose their effectiveness due to leaks and therefore need one constant observation.

Demgegenüber wird nach der Erfindung der erforderliche Druckunterschied im Augenblicke des Bedarfes durch chemische Hilfsmittel erzeugt, wobei die Geschwindigkeit der Entwicklung des Druckunterschiedes in an sich bekannter Weise durch chemische Veränderungen, z. B. Zusätze, oder durch Änderungen der Oberflächengrößen durch Drosselung usw. geregelt werden kann. So wird man dafür sorgen müssen, däß bei Verwendung derselben Bremse der Druckunterschied für Notbremsen von Förderkörben weit schneller anwächst als von Bahnen. Eine Vakuumbremse würde beispielsweise so beschaffen sein können, daß hinter dem mit der Außenluft in Verbindung stehenden Kalben im Zylinder selbst oder in einem damit in Verbindung stehenden Behälter sich N H3 oder S 02 von annähernd demselben Druck befindet, so daß die Abdichtung leicht ist. Durch die Einspritzung eines Absorptionsmittels, z. B. Wasser; oder andere Maßnahmen würden die genannten Gase absorbiert und mit großer Geschwindigkeit ein starkes Vakuum: erzeugt werden.In contrast, according to the invention, the required pressure difference Generated at the moment of need by chemical aids, with the speed the development of the pressure difference in a manner known per se by chemical means Changes, e.g. B. additives, or by changing the surface area Throttling, etc. can be regulated. So you will have to make sure that when you use it the same brake, the pressure difference for emergency brakes of conveyor baskets is much faster grows as from orbits. A vacuum brake, for example, would be designed in this way can that behind the calving in the cylinder in contact with the outside air itself or in a container connected to it N H3 or S 02 is of approximately the same pressure so that the seal is easy. By the injection of an absorbent, e.g. B. water; or other action would the gases mentioned are absorbed and at great speed a strong vacuum: be generated.

Bei mit komprimierten Gasen, also mit Überdruck arbeitenden Bremsen, würden die erforderlichen Gase in an sich bekannter Weise . durch chemische Reaktionen, z. B. durch Abbrennen von glicht explosiblen Gaserzeugungsmassen, erzeugt werden.In the case of brakes that work with compressed gases, i.e. with overpressure, would the required gases in a known manner. through chemical reactions, z. B. by burning off similarly explosive gas generating masses are generated.
