ABSTRACT:
A multi-stage compressor has a trap between adjacent stages to collect moisture from the compressed air passing from the exit of one compression stage to the entrance of the next compression stage. Each of the traps communicates with the next of the preceding traps through a bleed valve whereby moisture passes from one trap to another without having any effect on the substantial pressure differential between the two traps. The bleed valve has a diaphragm within a housing to divide the housing into first and second chambers with the first chamber communicating with the high pressure side trap and the second chamber communicating with the low pressure side trap. The flow from the high pressure side trap to the first chamber and the second chamber is controlled so that a predetermined pressure differential of one p.s.i. is maintained across the diaphragm.
