Line coupling, especially for automatic vehicle couplings «

The subject of the invention is an air line coupling for automatic vehicle couplings that connect to one another a compressed air line is provided with a transition piece that monitors the connection of a pneumatic actuator with the compressed air line and that monitors the transition piece.

In an air line coupling of this known type The shut-off valve works purely mechanically when! both coupling pins of the vehicle coupling driving organs open. Since it is wished, the "shut-off valve" first to open after the meohaniache connection of the two Coupling halves were already preferred, it was necessary to use the Motion transmission between the said drive members and to train the shut-off valve so that the latter-only at the end of the Adjustment of the drive elements was opened. As also the shut-off valves for the compressed air lines of vehicles considerable Durohlass cross-sections and therefore, relatively have large openings, this led to complicated and fault-prone movement transmissions between the drive elements and the shut-off valve.

. The invention aims to eliminate this disadvantage. According to the invention speaks to the closing of the coupling halves the auxiliary valve on and changed with a Glegerkupplungshalfte thereby the connection of the actuating element coupled to the shut-off valve with the compressed air line in such a way that the actuator is under the influence of the pressure of the compressed air line responds and the shut-off valve opens.

Since the auxiliary valve only monitors the connection of the actuator with the Druokluftleltung, while the pressure of the compressed air line _{for the Ver f position of the actuator}

The erfindungsgeraaß training also has the further advantage that the auxiliary valve can be made in any way the distance from the actuator for the shut-off valve resulting from the shape of the coupling halves "

When the two coupling halves to be coupled move together, the transition pieces 11, 12 first come into contact with the transition pieces 93 * 9 ^ opposite them and are pressed into their housing against the action of the springs 17 and 25. The teeth of the slide then engage 95 into the teeth of the slide 88, these slides also being displaced from the rest position shown in FIG. 3 into a working position When the coupling process for the mechanical connection of the two vehicles is terminated, the flange 85 grips the plunger 81 and thereby brings the valve body 73 to rest against the action of the spring 65 on the valve seat 76. At about the same time, the pawl 91 engages behind the flange 85. The actuation of the auxiliary valve 73 terminates the bore 75 and thus the chambers 67. » 69 from the valve chamber 72 and the connection of the latter and thus the chambers 66, 68 with the bore 82 and thus with the outside air continues to have access, the pistons 64, 65 are displaced against the action of the springs 25 and the two shut-off valves 16 are opened * 9 ^ of the mating coupling half made.

To release the air line coupling, it is sufficient * to release the mechanical connection between the two carriages and move them apart. The transition pieces 11, 12 separate from the transition pieces 93, 94 of the adjacent car, whereby the two lines 8, 9 are opened. If the shut-off valves 14 are to be closed, the crank 92 must be actuated. The flange 85 is rotated into a position in which it is out of contact with the plunger 81 and the pawl 91. The slide 88 and the auxiliary valve 73 therefore return to their rest positions shown in FIG. 3. The resulting connection of the chambers 66, 67 respectively. 68, 69 enables the springs 25 to move the pistons 64, 65 until the valve bodies 16 rest on their seats 14 «
