Coupling for hydraulic or pneumatic hose - has stops movable radially in apertures to provide securing or release positions

摘要

The coupling is for hoses used as hydraulic or pneumatic lines. A supplementary stop is formed by stops movable in radial apertures of a second valve guide, crossways to the path of movement of this second valve body. The stops are movable between a position, in which they are held by a movable casing and a release position in which they press into recesses of the casing. The casing is held by a relatively light spring in a position in which its recesses correspond with the apertures of the second valve body guide. A flow force acting on its free face side in the direction of the opening stroke of the second valve body can cause it to displace.
