Abstract: Filling machine including multiple valve groups, each having a supply channel connected to a containment tank, a first shutter actuatable by a first actuation body in order to open and close the supply duct, a return tube placed in the supply channel, and an evacuation chamber connected to the return tube and traversed by the first actuation body. In addition, each valve group comprises a first flexible membrane, placed as an upper hermetic closure of the supply channel to separate the latter from the evacuation chamber, and a second flexible membrane, placed as an upper closure of the evacuation chamber. The membranes are arranged for being deformed by the moving first actuation body.

Abstract: Bottling plant comprising a first transport system which moves containers through different machines, and a storage apparatus, which comprises a storage unit, a second transport system which extracts the containers from the first transport system to feed the storage unit, and a third transport system which picks up the containers in the storage unit to feed the first transport system. The first transport system comprises an upstream conveyor actuated at a first operative speed, and a downstream conveyor actuated at a second operative speed. The plant further comprises a control unit programmed with: a by-pass mode, in which it commands the conveyors with equivalent operative speeds, a storage mode, in which it commands the conveyors with the first operative speed greater than the second operative speed, and a recovery mode, in which it commands the conveyors with the first operative speed lower than the second operative speed.
