Screw compressor system

Abstract

A screw compressor system which is designed to be compact and flexible with a modular design such that a screw compressor block, an oil separation container, an oil supply duct for a temperature regulator and an air intake duct are combined in a base housing having a lid. A further module component provided is a multifunction block in which a fine separator, an oil return, a minimum pressure-maintaining valve with a pure air outlet, an oil temperature regulator, an oil filter and connections for a sensor are combined.

What is claimed is: 
     
         1 - 8 . (canceled) 
     
     
         9 . A screw compressor system, comprising:
 a screw compressor block,   a pressure control valve,   an oil separation tank,   an oil circulation system with an oil temperature controller,   an oil filter and connections for a cooler,   a fine separator with an oil return apparatus, and   a minimum pressure-maintaining valve with a clean air outlet, and   at least one of a base module component comprised of a base housing with a lid in which the screw compressor block, in which the oil separation tank, the oil supply duct for the oil temperature controller and the air intake duct are combined as individual modular units, and a second module component formed of a multifunction block with which the fine separator, the oil return, the minimum pressure-maintaining valve with the clean air outlet, the oil temperature controller, the oil filter and the connections for the cooler are combined as individual modular units.   
     
     
         10 . The screw compressor system as claimed in  claim 9 , wherein both said base housing with a lid in which the screw compressor block, the oil separation tank, the oil supply duct for the oil temperature controller and the air intake duct are combined and said multifunction block with which the fine separator, the oil return, the minimum pressure-maintaining valve with the clean air outlet, the oil temperature controller, the oil filter and the connections for the cooler are combined, are provided. 
     
     
         11 . The screw compressor system as claimed in  claim 10 , wherein the multifunction block is located on an operator side of the screw compressor system. 
     
     
         12 . The screw compressor system as claimed in  claim 10 , wherein the screw compressor block is located above an oil level in the base housing. 
     
     
         13 . The screw compressor system as claimed in  claim 10 , wherein an outlet tube, ribs and baffle plates are provided and through which a compressed air-oil mixture is routed, being repeatedly deflected by the ribs and baffle plates, from a front corner of the base housing above an oil level to an outlet opening which is located diagonally on another upper corner of the base housing and into the air intake duct to the fine separator. 
     
     
         14 . The screw compressor system as claimed in  claim 10 , comprising a plurality of different lids for the base housing, separation and oil tank volumes being variable by selection of different ones of the plural lids. 
     
     
         15 . The screw compressor system as claimed in  claim 10 , wherein different multifunction blocks which comprise different components according to size and number are connectable to the base housing. 
     
     
         16 . The screw compressor system as claimed in  claim 10 , wherein the multifunction block is constructed in a manner enabling the minimum pressure-maintaining valve with the clean air outlet to be installed in different directions and set for different pressures. 
     
     
         17 . The screw compressor system as claimed in  claim 10 , wherein an oil fill fitting having vertical position which determines the oil level is located is located on a corner between an operator side and a drive side of the base housing. 
     
     
         18 . The screw compressor system as claimed in  claim 10 , further comprising an air filter apparatus.
