Summary

AS ENERGY COSTS OVER THE YEARS AMOUNT TO SOME 70% OF THE TOTAL COSTS OF OWNING AND OPERATING A PISTON COMPRESSOR AND VALVE LOSSES MAY BE SIGNIFICANTLY HIGH, ESPECIALLY WITH HEAVY GASES LIKE R13, ANY IMPROVEMENT IN VALVE DESIGN CAN CONTRIBUTE GOOD SAVINGS. THE TYPE OF VALVE DESCRIBED IS A MULTI-RING DISK TYPE OF CONVENTIONAL DESIGN. TESTS WERE MADE OF PRESSURE LOSS THROUGH THE VALVE ALONE MOUNTED IN A TUBE RIG, WITH AN ADDITIONAL RESTRICTION REPRESENTING THE CYLINDER GEOMETRY, AND WITH THE VALVE MOUNTED AS NORMAL IN A CYLINDER. IT WAS FOUND THAT INCREASES IN VALVE LIFT WERE EFFECTIVE UP TO A POINT AND ALSO A BETTER GEOMETRY OF THE VALVE LIFT LIMITER OR CAGE. SMALL BENEFITS COULD ALSO BE OBTAINED BY CHANGES IN CYLINDER PASSAGE AREA. IN ALL, WITHOUT MAJOR REDESIGN, A 4% REDUCTION IN POWER CONSUMPTION COULD BE OBTAINED WHEN COMPRESSING R13 UP TO A PRESSURE RATIO OF 2.5. D.W.H.
