Disconnectable connector for high-pressure hydraulic circuits

摘要

Connector for hydraulic circuits, composed of a fixed element (10) comprising an overall cylindrical body (12) housing a valve with a seat (34) and closure capsule (42) which are frustoconical, and of a movable element (11) also comprising an overall cylindrical body (68) housing a valve with the seat (98) and closure capsule (104) which are frustoconical, one of the two elements carrying a tapped ring (132) and the other carrying a screw thread (38) on which the said ring is screwed upon coupling, characterised in that each valve closure capsule (42, 104) comprises a central rod (46, 112) forming, in the respective body, an annular flow stream and which is retained in the said body by a centring member (52, 116) equipped with axial passages (58, 126), and in that the two frustoconical valves are located substantially in the extension of one another when the two elements are coupled.
