Coupling element for a coupling for connecting pressure medium lines

A coupling element for a coupling for connection of pressure medium lines, comprising a housing, a flow channel for a pressure medium, a valve tappet, a pressure sleeve and an inner body, wherein the housing has a coupling axis A, wherein the valve tappet is mounted in the housing such that the valve tappet is arranged in the flow channel, wherein the valve tappet has a valve tappet head, wherein the pressure sleeve surrounds the valve tappet, wherein the pressure sleeve is held in a movable configuration along the coupling axis A between a closed position, in which the flow channel is closed by the pressure sleeve, and an open position, in which the flow channel is opened by the pressure sleeve, wherein the pressure sleeve is in at least indirect contact with the valve tappet head when in the closed position, wherein a force from the pressure sleeve parallel to the coupling axis A acts upon the valve tappet head,

• further comprising wherein the inner body or the pressure sleeve has means for limiting the force from the pressure sleeve upon the valve tappet head, the means is formed as a first limit stop on the inner body, and as a second limit stop on the pressure sleeve, wherein the first limit stop and the second limit stop interact for limiting the force, the first limit stop and the second limit stop are spaced apart from one another at least in an unpressurized closed position of the pressure sleeve.
