The rapid release coupling (Patent Nr. EP 161852967) at hand is a detachable, coaxial connection of hose lines for suction devices, in particular for industrial suction devices (e.g. super suction cups, canal cleaning vehicles, air conveyor systems, suction dredgers etc.).
It consists of 3 elements, made of 0,002 [m] strong stainless steel sheets, connected by joints. A foam rubber is used to ensure tightness. The foam rubber is glued inside the coupling and the blunt ends of the hoses are deposited in the middle of the open coupling.
