ABSTRACT:
A scavenging system for single screw compressors to remove residual liquid eal from an open combustion chamber prior to controlled liquid seal injection. The removal of residual liquid seal is accomplished by providing the casing with a scavenging slot which surrounds a portion of the open combustion chamber thereby allowing centrifugal force to radially remove residual liquid seal.
