  • Patent number: 7052249
    Abstract: A group is provided for a compressed air distribution unit of the type including an intake regulator, an oil bath-screw type compressor, an air/oil separating tank, a minimum pressure valve, an air cooling radiator, a pressurized air collection tank, a thermostatic valve, and an oil cooling radiator, wherein the group includes the air/oil separating tank, the thermostatic valve, the minimum pressure valve, the oil cooling radiator, the air cooling radiator all connected to a cover for the air/oil separating tank resulting in a single-block group.

  • Patent number: 6811384
    Abstract: An automatic regulator of the air intake in a tank installed in a circuit for the production of compressed air wherein the regulator provides that the intake orifice (7) which aspires external air is operated in opening/closing by means of a disk shutter. The disk shutter is provided with a tang which idly slides on a central hub. The disk shutter is subjected to the biasing action of a spring which sits in the hub and to the balancing action of a flux of air removed from the separator tank.

  • Patent number: 6736884
    Abstract: An air/oil separation tank for installation in a circuit for the production of compressed air, the circuit including an intake regulator (1) which intercepts external air and sends the air to an oil bath spin compressor (2) which is activated by an electric motor (3). The pressurized air/oil mixture produced by the compressor, passes through conduit (4) to enter separation tank (5) in which the separation of the oil from the air occurs. The air under pressure passes through radiator (6) and fills accumulation tank (7) waiting to be used, while the oil (8) deposited at the bottom of the separator, is picked up by conduit (9) and passes through radiator (10) to be brought again to compressor (2). This separation tank is characterized by the fact that the entry port of the air/oil mixture is placed on the upper wall or cover of the vessel.

  • Patent number: 6715998
    Abstract: The intake regulator of air (1) in a reservoir to be installed in a circuit for the production of compressed air, intercepts the air from the exterior and conveys the air to an oil bath spin compressor (2). The regulator is characterized by the fact that it is also fed by two flows of air under pressure (13 and (14), removed from the separator reservoir (3) and intercepted by three electrovalves (15), (16) and (17).
