Appl. No.:

8/036716

Inventors:

Daniel M. Allen - Middletown OH

Assignee:

Dover Corporation - New York NY

International Classification:

F16L 3700

US Classification:

285312

Abstract:

A quick connect/disconnect coupling comprises locking levers. Pull rings facilitate pivoting of the locking levels to a release position. The pull rings are resiliently mounted on the levers in positions that prevent the pulls rings from interfering with movement of the locking levers to their locking positions.

International Classification:

F16L 3728

US Classification:

13761406

Abstract:

A coupling for connecting fluid conduits comprises a coupler and an adapter. The coupler has a frusto-conical seat at its distal end. Fixed and pivotal jaws project beyond the frusto-conical seat and are engageable with a clamping surface on the adapter. A lever operated, cam member swings the pivotal jaw to a position in which the coupler is locked in sealed relation on the adapter. An interlock rod prevents rotation of the lever from this rest position unless the coupler is positioned to be locked on the adapter. The coupler and adapter each comprise normally closed poppet valves. When the operating lever is swung from its rest position to a ready position, the pivotal jaw is swung to its locking position. When the operating letter is swung to a further angular extent, to a full flow position, the coupler poppet is displaced outwardly by a crank/link mechanism. When the coupler poppet is so displaced, it engages the adapter poppet and positions both poppets in open positions, interiorly of an adapter housing passageway.
