Summary

A TEST RIG HAS BEEN BUILT TO MEASURE THE GAS FORCE ON THE VALVE PLATE AND THE OIL STICKING FORCE BETWEEN THE PLATE AND VALVE SEAT OF A REFRIGERATION RECIPROCATING COMPRESSOR. THE CONCLUSIONS ARE: 1) THE THEORETICAL GAS FORCE = C X PRESSURE DIFFERENCE ACROSS THE VALVE X PLATE SURFACE AREA CAN BE SUBSTITUTED FOR THE MEASURED REAL GAS FORCE IF THE VALUE OF THE COEFFICIENT OF PRESSURE DRAG C = 0.6 IN THE MATHEMATICAL MODEL ; 2) THE TIME DELAY OF VALVE ACTION FROM THE SEAT DUE TO THE OIL STICKING HAS SIGNIFICANT INFLUENCE ON THE PERFORMANCE OF A COMPRESSOR AND ITS VALVES.
