ZERBRECHLICHES VENTILFITTING

摘要

A valved fluid coupling having tubular halves interconnected by frangible means. Each half includes a self-closing valve located in its passage and the valves are maintained in an open position by supports and retainers which sense the coupling connected state. Upon fracture of the connection means the halves separate permitting the valve retainers to release the valves closing the body passages. The frangible connection means takes the form of a rib formed upon one half overlapped by a projection defined on the other half having a retainer engaging the rib. Axial forces of a predetermined value on the halves cause the rib to fracture. Also, frangible means are disclosed for permitting valve half separation under radial shear forces and a sealing boot may be used to minimize fluid loss upon coupling disengagement.
