  • Coupling part for a coupling for pressure medium lines
    Patent number: 9709199
    Abstract: A coupling part coupling with a corresponding coupling part of a coupling for pressure medium lines has a housing having a flow channel and a coupling axis, and a sleeve-like closing valve displaceable back and forth axially within the flow channel, for closing off the flow channel in the uncoupled state of the coupling part. The closing valve has a closed valve position and an open valve position, closing off and not closing the flow channel, respectively. A plunger within the flow channel displaceable back and forth axially drives the closing valve in a valve opening direction during coupling. A plunger pin between the plunger and the closing valve within the flow channel, displaceable back and forth axially, transfers the movement of the plunger in the valve opening direction to the closing valve. The plunger pin is connected with the closing valve so as to be non-displaceable axially.
