Die bisher bekannten Wechselvorrichtungen für Verbund-Lokomotiven arbeiten bei der Zwillingswirkung mit Drosselung des Dampfes, deren Höhe entweder nicht bestimmt festgelegt werden kann, oder welche, falls eine Druckregulirung vorgesehenThe previously known changing devices for composite locomotives work at the Twin effect with throttling of the steam, the level of which is either not determined can be, or which, if a pressure regulation is provided

ist, die Einrichtung sois the establishment like that

complicirt macht, dafs dieselbe betriebsunsicher wird und einen grofsen Verschleifs aufweist.makes it complicated that it becomes operationally insecure and shows great wear and tear.

Der Gegenstand der Erfindung betrifft nun eine Anfahrvorrichtung für Verbund - Lokomotiven, welche ohne eine selbsttätige oder von Hand bewirkte Umschaltung der Zwillingswirkung in die Verbundwirkung, sofort beim Anfahren, beim ersten Hub eine vollständige Verbundwirkung erzielt, so dafs diese Lokomotive in ihrer Wirkung .in Bezug auf das Anfahren der Zwillingsmaschine gleichkommt, in Bezug auf Dampfausnutzung dieVortheile der Verbundwirkung für sich in Anspruch nimmt.The object of the invention now relates to a starting device for composite locomotives, which without an automatic or manually effected switchover of the twin effect into the composite effect, immediately at Starting up, achieving a complete compound effect on the first stroke, so that this locomotive in their effect. is equivalent to starting the twin machine, takes advantage of the composite effect in terms of steam utilization.

Die wesentlichen Vorzüge der vorliegenden Construction sollen darin liegen, dafs dieselbe für Rangir-Lokomotiven verwendbar ist und gestattet, die-Lokomotiven beim Anhalten durch eine passende Gegendampfwirkung schnell zum Stillstand zu bringen, ohne die Steuerung umlegen zu müssen.The essential merits of the present construction are said to be that it is the same Can be used for Rangir locomotives and allows the locomotives to stop by to bring a suitable counter-steam effect to a standstill quickly without having to flip the control to have to.

In der beiliegenden Zeichnung zeigt Fig. 1 die Vorderansicht einer mit der neuen Vorrichtung ausgerüsteten Lokomotive, während die Fig. .2 bis 6 verschiedene Lagen des Umschalthahnes und die zugehörigen Lagen des Regulatorhebels darstellen.In the accompanying drawing, Fig. 1 shows the front view of a locomotive equipped with the new device, while Figs. 2 to 6 show different positions of the switch valve and the associated positions of the regulator lever.

In das Verbinderrohr sind zwei Rundschieber s und d (Fig. 1) eingeschaltet, welche . zwischen sich einen bestimmten Theil (etwa die Hälfte) des Gesammtaufnehmervolumens, ■· von Hochdruckcylinderauslafs bis Niederdruck cylindereinlafs, abzuschliefsen gestatten. Die Schieber sind beide zwangläüfig mit dem Regulatorhebel h verbunden, d ist lediglich ein Absperrorgan, während s ein Rundschieber mit drei Kanälen ist.In the connector tube two round slides s and d (Fig. 1) are switched on, which. between them a certain part (about half) of the total pick-up volume, from high pressure cylinder outlet to low pressure cylinder inlet. The slides are both positively connected to the regulator lever h , d is only a shut-off device, while s is a round slide with three channels.

Stehen der Regulatorhebel h und der Schieber s in Stellung I, so schliefstuf den Zugang zum Niederdruckcylinder ab, während 5 durch die Kanäle f und r die Verbindung des Aufnehmers . mit dem Kessel herstellt. Der Auf_T nehmer hat alsdann die Spannung des Kessels und diese Spannung bleibt erhalten. Der Hochdruckylinder steht durch die Kanäle a und b mit dem Auspuff in Verbindung. Es entspricht diese Stellung dem längeren Aufenthalt auf Stationen oder der Fahrt im Gefälle oder allgemein der Fahrt ohne Dampf, wobei also kein Gegendruck auf den Hochdruckcylinder wirken darf.If the regulator lever h and the slide s are in position I, the access to the low-pressure cylinder is closed, while 5 the connection of the transducer is through the channels f and r. with the boiler. The On _T participants has then the power of the boiler and this tension is maintained. The high pressure cylinder is in communication with the exhaust through channels a and b. This position corresponds to a longer stay on stations or driving downhill or generally driving without steam, so that no counter pressure may act on the high-pressure cylinder.

Wird der Regulatorhebel h nur bis zur Stellung II (Fig. 3) zurückgeführt, so kann kein Frischdampf in die Aufnehmerleitung r gelangen, während die Aufnehmergegenspannung auf den Hochdruckcylinder auch hier fortfällt. Diese Stellung gewinnt dann Bedeutung, wenn, wie weiter unten näher erläutert, Regulatorhebel h und Schieber s während einiger Kurbelumdrehungen in Stellunglll (Fig. 4) zwecks schnellen Anh$ltens belassen worden sind und somit in dem zwischen s und d abgetrennten Aufnehmervolumen die Kesselspannung schon entstanden ist, also eine besondere Frischdampfzuführung überflüssig wird. .. 'If the regulator lever h is only returned to position II (FIG. 3), no live steam can get into the sensor line r, while the counter-tension of the sensor on the high-pressure cylinder is also eliminated here. This position becomes important when, as explained in more detail below, the regulator lever h and slide s have been left in position III (Fig. 4) for a few turns of the crank for the purpose of rapid stopping, and thus the boiler voltage in the transducer volume separated between s and d has arisen, so a special live steam supply is superfluous. .. '

Claims

Regulator lever h and slide in position 111. The shut-off element in the dome still lets steam into the high-pressure cylinder, which, however, cannot get into the low-pressure cylinder because it is still shut off by d. The steam from the high-pressure cylinder is therefore pumped into the transducer and there compressed, resp. pushed back into the boiler by a safety valve. If the regulator lever h is left in this position III for a long time, a strong but permissible counter-steam effect on the high-pressure piston and thus a quick stop is achieved, without having to turn the control over. The same "steam" that occurs here as counter-steam is used again afterwards for start-up.

If the regulator lever h is brought to position IV, d gives access to the low-pressure cylinder and s connects the transducer with the high-pressure cylinder. The vapor of boiler voltage contained between s and d now expands to the total pick-up volume and its voltage goes down to the usual pick-up voltage, which is otherwise quite arbitrarily large, corresponding to the respective volume ratios. ■. .

Starting in every crank position with a certain pressure, immediately with full compound effect, without actuating a special lever, without the action of a changing device is ensured. The inevitable movement of the slide from the regulator lever h does not require any special practice on the part of the operator.

If the regulator lever h is moved beyond position IV into position V, s and d remain in their position as a result of a corresponding lever construction and suitable overlaps. This latter movement of the lever h corresponds to only one further opening of the slide in the dome.

In order to achieve the greatest possible starting torque when starting, the steam contained in the connector should not exert any counter pressure on the high-pressure piston at first. Therefore, a check valve or flap of the simplest construction is attached between the high pressure cylinder outlet and slide s, directly on the high pressure cylinder. When starting, where s is in position IV and. d the compound of the transducer producing the LP cylinder, the vapor contained in the connector, which then, as explained in detail above, the ordinary Aufhehmerspannung has (about half of the boiler voltage) ,, conclude this check valve. The high-pressure cylinder then works at this moment without counter-steam. With the next stroke, however, the steam coming from the high-pressure cylinder will open the valve, switch off its effect completely and assume the voltage of the pick-up steam.

A strong spring prevents small pressure fluctuations from causing the valve to move. ^:

Thus the locomotive constructed according to the foregoing principles is always a very, large one Have starting torque and still work as a compound machine on the first stroke.

It deserves to be particularly emphasized that the low-pressure piston and thus the linkage on the low-pressure cylinder side is never subjected to excessive stress is subjected, as is the case with many start-up devices, namely when the start-up does not take place quickly enough and so the throttled one flowing through small openings to the low-pressure cylinder Boiler steam gradually but inadmissibly high voltage in front of the low-pressure piston accepts.

Ρλτενt-AnsrRUcη:
Device for facilitating the start-up and stopping of composite locomotives, characterized in that two: slides fs and d) moved by the regulator lever and arranged in the transducer line, for the purpose of working with a composite effect when starting as during normal travel, the connection of the transducer with the high-pressure and the low-pressure cylinder and, when at a standstill, connect part of the transducer to the steam boiler, while when stopped, the part on the low-pressure side. Slide (d) shuts off the low-pressure cylinder from the transducer, so that the compression of the steam coming out of the high-pressure cylinder creates a counter-pressure by which the machine can easily be brought to a standstill.
