  • Patent number: 5316033
    Abstract: The invention concerns a coupling for connecting hydraulic lines having a first coupling part 1 with a first valve 6, which is received into a housing 3, and including means for receiving a second coupling part 2, which includes a second valve 64. The truncated conical valve body 30 of first valve 6 is urged in the closing direction by a separate closing spring 33. Valve body 30 of first valve 6 is then penetrated by an actuator, which is adjustable in the direction of second valve 64, and which actsacross an actuating surface cooperatively with an actuating shaft 7 disposed diagonally to the valve axis and penetrates housing 3 of first coupling part 1, which actuating surface, on the one hand, acts on valve body 30 of first valve 6 and, on the other hand, on an actuator 35. The actuator 35 is urged toward actuating surface 22 by means of an opening spring 37 supported by valve body 30.
