DEVICE TO DISMANTLE AND MOUNT PNEUMOHYDRAULIC SYSTEM WITH HYDRAULIC JOINT PLUG-IN ELEMENTS (VERSIONS) Russian patent published in 2011 - IPC B64G1/66 F16L37/00 

FIELD: transport.

SUBSTANCE: proposed device comprises pipelines 2, joints 3 and hydraulic connectors 4 connected to inlet and outlet of replaceable unit. Said hydraulic connectors consist of replaceable and unchangeable parts 5 and 6, respectively. Every joint 3 consists of union, tip, seals and cap nut (not shown). Joint axis is parallel with that of hydraulic connector 4 to rule out skew in handling hydraulic connector. In compliance with first version, sleeve is fitted on joint 3 to limit travel of its part in uncoupling hydraulic connector. Sleeve lugs are clamped with two semi-straps embracing cup but. Said cup nut has annular limiter inhibiting uncoupling of other elements on unscrewing said nut. In compliance with second version, inner space of aforesaid union is provided with support with central smoothbore jointed by union inner surface by ribs. Tip inner space has threaded support with central threaded bore engaged with tip inner surface by ribs. Screw passing through union support smooth bore is screwed in threaded support. Length of screw and other elements is selected to inhibit uncoupling in unscrewing cap nut.

EFFECT: easier of work in zero-gravity conditions, lower weight of pipelines connected to units.
