PATENTAMT.PATENT OFFICE.
Den Gegenstand der vorliegenden Erfindung bildet eine dahingehende Verbesserung der durch das Patent Nr. 9681 5 geschützten Regulirvorrichtung, dafs dieselbe, bei Schiffsmaschinen angewendet, schon vor der Aenderung der Umdrehungszahl in Thätigkeit tritt.The subject of the present invention is an improvement to that effect regulating device protected by patent no. 9681 5, that the same, applied to ships' engines, comes into action before the number of revolutions is changed.
Die Verbesserung bezweckt also, -den Apparat nicht durch Geschwindigkeitsänderungen wirken zu lassen, sondern solche womöglich überhaupt zu vermeiden.The aim of the improvement is to prevent the apparatus from acting through changes in speed to leave, but to avoid them at all, if possible.
Die hierzu getroffene und in der Zeichnung dargestellte Anordnung ist die folgende:The arrangement made for this and shown in the drawing is the following:
Der Kolben K einer Stellhemmung, welche die Verstellung der Drosselklappe bewirkt, wird gesteuert durch einen Kolbenschieber S, der nach erfolgter Function vom Kolben K in seine Anfangslage zurückgebracht wird. Die Bewegung des Schiebers S erfolgt durch ein Solenoid S1, welches einen mit dem Querhebel Q gelenkig verbundenen Eisenkern K1 anzieht, und zwar um so stärker, je stärker der das Solenoid durchfliefsende Strom ist. Diese verschiedenen Stromstärken werden wie folgt erhalten:The piston K of a locking mechanism, which effects the adjustment of the throttle valve, is controlled by a piston slide S, which is returned to its initial position by the piston K after the function has been completed. The slide S is moved by a solenoid S 1 which attracts an iron core K 1 articulated to the transverse lever Q, the stronger the stronger the current flowing through the solenoid. These different currents are obtained as follows:
Von dem Accumulator A geht der Strom durch den Rheostaten R, dessen verschiedene Widerstände durch den Gleitcontact G geschlossen werden. Die Bewegungen dieses Gleitcontactes G werden dem Austauchen der Schraube proportional gemacht, um eine Aenderung der Maschinenleistung schon vor der Geschwindigkeitszunahme zu bewirken. Dieser Zweck wird erreicht durch eine Plattenfeder P, welche ein mit dem Meer in Verbindung stehendes Rohr C abschliefst. Taucht nun das Heck des Schiffes mehr oder weniger aus dem Wasser, so ändert sich gleichzeitig die über dem Rohr stehende Wassersäule. Die hierdurch verursachten Druckschwankungen übertragen sich auf die Plattenfeder P und von dieser mit Uebersetzung auf den Gleitcontact G, wodurch das Solenoid S' den Schieber und mit diesem den Kolben K und die Doppelklappe verstellt.The current goes from the accumulator A through the rheostat R, the various resistances of which are closed by the sliding contact G. The movements of this sliding contact G are made proportional to the displacement of the screw in order to bring about a change in the machine performance even before the increase in speed. This purpose is achieved by a plate spring P which closes off a pipe C connected to the sea. If the stern of the ship dips more or less out of the water, the water column above the pipe changes at the same time. The pressure fluctuations caused by this are transmitted to the plate spring P and from there with translation to the slide contact G, whereby the solenoid S 'moves the slide and with it the piston K and the double flap.
In dieser Weise wirkt die Vorrichtung beim Stampfen des Schiffes. Um bei einem Wellenbruch das Durchgehen der Maschine zu verhindern,, ist ein Centrifugalregulator Z angebracht, der bei Ueberschreitung einer bestimmten Maximaltourenzahl den Strom durch den kleinsten Widerstand W leitet und dadurch das Drosselventil schliefst oder aber mittelst eines besonderen Solenoids den Dampt'umsteuerungsapparat schliefst.In this way the device acts when the ship is pitched. In order to prevent the machine from running away in the event of a broken shaft, a centrifugal regulator Z is attached which, when a certain maximum number of revolutions is exceeded, conducts the current through the smallest resistance W and thereby closes the throttle valve or, by means of a special solenoid, closes the damper reversing apparatus.
Um ein wirksames Reguliren zu ermöglichen, befindet sich ein derartiges Drosselventil nicht nur in der Hauptdampfleitung, sondern auch in der Abdampfleitung vom Niederdruckcylinder zum Condensator, um den in ersterem thätigen Gegendruck erhöhen zu können.In order to enable effective regulation, there is no such throttle valve only in the main steam line, but also in the exhaust line from the low pressure cylinder to the condenser, around the in the former to be able to increase the counterpressure.
