mechanical entsperrbare fluidkupplung for mehrwegbehältnisse with external forced ventilation for the transport, storage and withdrawal of fluids, as well as the connection and to secure a fluidsystem

摘要

The unlockable fluid coupling has two connections, two successively cut-off valves arranged in parallel, a mechanical operation and/or a mechanical coupling. At least one assembly (1) arranged on the suction side (2) of a fluid system (3) contains a coupling half (4) on the container (5) with a cut-off valve (7), together with a venting valve (8) connected in parallel. It also contains a further coupling half (9) in the system suction line (10), with a suction valve, together with a parallel-connected back unloading valve (12), both connected to a venting channel (13) for the venting valve (8), in front of which is a moisture filter (14) and/or a venting filter, together with a mechanical operating device (16). Both coupling halves (4, 9) are provided with a mechanical coupling arrangement. USE/ADVANTAGE - An unlockable fluid coupling for multi-path containers, partic. for engine oils, with protection against hydraulic excess pressure whilst the system is at rest.
