Abstract: The invention relates to a volumetric compressor (100) including a container (51) for collecting the lubricant moved by an oil distribution disc (1). The compressor (100) further comprises at least two lubricant distribution channels (52), in which each lubricant distribution channel (52) extends from the collecting container (51) so that during operation, the lubricating oil flowing along the channel itself reaches a lubrication opening (82) of a lubrication duct (81) for a rolling bearing (90) of a rotor (80?, 80?). The lubrication opening (82) is arranged at a lower level with respect to the container (51).

Abstract: Volumetric compressor (1) for collection and/or treatment equipment of material in liquid, solid, dusty or muddy form. The compressor (1) comprises an operative chamber (50), defining a suction section and an exhaust section of a first fluid, a first header (61) and a second header (62), which delimit said chamber (50) on opposite parts along a longitudinal axis (101). The compressor further comprises at least two rotors (80?, 80?) with lobes (81?, 81?) housed in the chamber (50), each rotor (80?, 80?) rotating about a rotation axis (108?, 108?) substantially parallel to said longitudinal axis (101). The lobes of each rotor develop according to a helical profile. Furthermore, each of the headers (61,62) defines at least one injection opening (71?, 71?,72?,72?) communicating with a feeding device (150) of a second fluid.

Abstract: The invention relates to a suction/compression assembly for aspirating/compressing gases from/in a system to/from an external environment. The assembly comprises an operating machine, a four-way valve, an intake pipe and an exhaust pipe connecting an intake section and an exhaust section of the operating machine to said four-way valve, respectively. The assembly is characterized in that it comprises a first body, which defines, in one piece, a chamber of the operating machine, a first portion of the intake pipe and a first portion of said exhaust pipe. The assembly further comprises a second body, which defines, in one piece, a seat of the four-way valve, a second portion of the intake pipe and a second portion of the exhaust pipe. Moreover, the assembly according to the invention comprises a one-way valve arranged within the intake pipe in a position adjacent to the seat of the four-way valve.

Abstract: The invention relates to a suction/compression assembly for aspirating/compressing gases from/in a system to/from an external environment. The assembly includes an operating machine comprising a body, which defines a chamber, within which one or more rotors are housed, rotating about a corresponding rotation axis. Such a chamber has a symmetrical transverse section evaluated on a plane with respect to at least one first reference plane on which said rotation axis lies. The assembly comprises a device for injecting gas into said chamber which comprises a manifold, connectable to an external source, and a plurality of injection pipes connected to the manifold and to the body of the machine. The body defines a plurality of injection passages, each of which is configured to make one of said injection pipes communicating with the chamber of the machine.
