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. In order to attain a simplified assembly, the actuating surface is part of a separate actuating member 18, which is attached non-rotatably to an actuating shaft 7, which is divided into two partial shaft pieces 8, 9.
