Eine an den Hängeböcken 1 und 2 befestigteOne attached to hanging trestles 1 and 2

Pumpe 3 bekannter Art (Fig. 3) ist durch das über die Seilscheiben 4 und 5 geführte Seil 6 mit der Wagenachse 7 verbunden und versetzt bei der in der Pfeilrichtung (Fig. 2) stattfindenden Bewegung" des Wagens 8 eine in Rohren 9 und IO und in der Pumpe 3 selbst befindliche Flüssigkeit in einen Kreislauf. Jedes der Rohre 9 und 10 ist einerseits mit dem Gehäuse der Pumpe, andererseits mit einem Gehäuse verbunden, in dessen Hohlraum ein Kolben 19 verschiebbar ist. Außerdem sind beide Rohre durch ein Rohr 13 miteinander verbunden. Die Flüssigkeit schließt durch ihren Druck ein im Rohre 10 befindliches Ventil 11 und versperrt den Durchfluß durch das Zwischenröhr 13 durch ein in das Rohr eingefügtes Kugelventil 15. An der Stelle, wo das Kugelventil liegt, ist das Rohr 13 mit dem den Kolben 19 aufnehmen-,den Gehäuse durch - ein Rohr an den Zylinder 17 in der Weise angeschlossen, daß eine Verbindung des Gehäuses 17 mit dem einen Rohr 9 oder 10 vorhanden ist, während das andere Rohr 10 oder 9 durch die Kugel des Ventiles vom Zufluß 16 des. Gehäuses 17 abgeschlossen ist. Bei Bewegung" der Flüssigkeit m der Richtung der Pfeile 2 (Fig. 2) tritt demnach die Flüssigkeit nach Schluß des Ventiles 11 und Abschluß der mit dem Rohr 9 verbundenen Hälfte durch das Kugelventil 15 in den Zylinder 17 ein. Hier treibt die stetig nachdrückende Flüssigkeit den nach Art der hydraulischen Pressen im Zylinder 17 angeordneten und durch die Liderung 18 angedichteten Kolben 19 nach außen, bis sie durch die freiwerdende Öffnung 20 und durch das mit Ventil 12 versehene Rohr 9 nach der Pumpe 3 zurückfließt. Die in den Leitungen 9 und 10 angeordneten Ventile 11 und 12 können u. U. in Wegfall kommen, da erst mit dem Freiwerden der Öffnung 20 die in gleicher Höhe befindliche öffnung 21Pump 3 of a known type (Fig. 3) is guided by the pulleys 4 and 5 Cable 6 connected to the carriage axis 7 and offset in the direction of the arrow (Fig. 2) movement "of the carriage 8 taking place in pipes 9 and IO and in the pump 3 self-contained liquid in a circuit. Each of the tubes 9 and 10 is on the one hand connected to the housing of the pump, on the other hand with a housing, in its cavity a piston 19 is displaceable. In addition, both pipes are through a pipe 13 connected with each other. The pressure of the liquid causes it to close in the tube 10 Valve 11 and blocks the flow through the intermediate tube 13 through a into the Tube inserted ball valve 15. This is where the ball valve is located Tube 13 to receive the piston 19, the Housing through - a pipe connected to the cylinder 17 in such a way that a Connection of the housing 17 with the one pipe 9 or 10 is present, while the other pipe 10 or 9 closed by the ball of the valve from the inlet 16 of the housing 17 is. When moving "the liquid m the direction of the arrows 2 (Fig. 2) occurs accordingly, the liquid after the closure of the valve 11 and the completion of the Pipe 9 connected half through the ball valve 15 into the cylinder 17. Drifting here the steadily pressing down fluid is like hydraulic presses in cylinder 17 arranged and sealed by the Liderung 18 piston 19 to the outside until they through the opening 20 that has become free and through the pipe 9 provided with valve 12 the pump 3 flows back. The valves 11 arranged in lines 9 and 10 and 12 can, under certain circumstances, be omitted, since only when the opening 20 becomes free the opening 21 located at the same height

Claims

becomes free; consequently, the can then enter the openings 16 and 21 at the same time, hydraulic fluid that escapes does not cause any harmful fluctuations on the piston. Due to the constant circulation of the liquid generated during the journey, the Piston 19 held at a certain height; and the cylindrical inside Steel spring 22 against the one on the hanging trestle 1 and 2 attached piston guide 23 pressed.

With the at the head of the piston 19 means the bolts 24 movably arranged levers 25 are on shafts 28 and 29 .sitzende Lever 26 by the bolts 27 in an articulated connection, so that by means of the lever pairs 25 and 26 the rectilinear movement of the piston 19 on the shaft 28 as clockwise and is transmitted to the shaft 29 as a counter-clockwise motion. At the other ends of the under the car body in bearings 30 held shafts 28 and 29 are levers 31 and 32 attached, which with the in the walls displaceably mounted tie rods 34 and 35 by slots 53 (Fig. 2) are connected in such a way that they at Rotation of the lever can be moved axially. By moving the tie rods 34 and 35 are connected to this double-armed lever 36, which laterally to the Car doors rotatably mounted in the interior of the walls by means of the pin 37 and attached to the upper ends are hook-shaped, shifted in such a way that they are hook-shaped with their Grasp heads over the latched latch 38 of the doors and thus secure them against opening. In addition, the upper lever arms 36 each have a mandrel 39 attached, which when one of the levers deflects

engages in the opening 40 of the door and secures it against opening, even if the bolt 38 is not properly latched.

If one of the doors secured in this way is to be opened while driving, then by means of

4-5 any shaped key 41 one through a spiral spring 42 pressed thumb disk 43 down to the stop 44 turned around; the disc pushes the lever 36 sideways so that the door is unobstructed can be opened.

Since the tie rods 34 and 35 move the lever 36 or one of the same do not allow, the slots 45 located in the same are expanded in the shape of a frame (Fig. 1) and in them with cylindrical steel springs 46 connected, slidable blocks 47 used, so that by pressing together the springs 46 influenced slide 47 to give way to the levers 36 pressing sideways.

6a after the turning back of the disc 43 of the spring 46 connected to the slider 47 pushes the lever 36 back and secures the door ¹ so against opening.

To offset 35 also zu.derselben to 90 ^0, the movement of the tie rod to transmit under the weighing housing 52 in slidably mounted rod 48 is at the relevant point of the former a wedge-like, ini angle slotted disc 49 used. The rod 48 engages in the slot with a pin or roller 50, so 'that when the pull rod 35 is displaced along its side, the rod 48 is displaced perpendicular to it. The connection of this rod to the locking devices for the door is the same as for rod 35.

When the carriage and the pump 3 come to a standstill, the piston 19 presses located steel spring 22 the same in its starting position and with it by the Linkage 25, 26, 28, 29, 31, 32, 34 and 35 connected lever 36 back so that the opening the doors can be done. The balancing of those located in the tubes 9 and 10 Columns of liquid take place instantaneously, since the columns stored in the intermediate pipe 13 Ball 15 and that seated in valve 11 Cone 54 fall back into their previous position due to their gravity and the related Release openings.

If the direction of movement of the carriage 8 and therefore also that of the pump 3 is opposite directed, the fluid cycle also takes place in the opposite direction Senses. ■
