Abstract (en)

[origin: EP0855519A2] The unit has an intake regulator (002), an oil bath screw compressor (003) and an air/oil separator (004) and an accumulator tank (005). The distributor (001) itself comprises a one-piece metal housing with cavities for two fixed throttling valves, a rapid discharge valve, an air injection control valve, a proportional control valve and two selector valves. The valves are connected by a series of channels and branches inside the housing, and the distributor is fed through a single duct (007) which takes air from the air/oil separator, and has four outlets, two with discharge regulating screws and another with a minimum pressure control screw.
