Abstract
Abstract IN PREFERRED FORM, A GAS COMPRESSOR USED IN THE CONTROL SYSTEM OF A HOT GAS ENGINE POWERING A VEHICLE WITH HIGH FREQUENCY OF LOAD CHANGE. THE COMPRESSOR PROVIDES PLURAL ACCUMULATORS WHICH ARE SEQUENTIALLY DISCHARGED BY FLUID FROM A CONSTANTLY RUNNING OIL PUMP. THE ACCUMULATORS NOT BEING DISCHARGED ARE AVAILABLE TO RECEIVE GAS FROM THE ENGINE WORKING CHAMBER, PERMITTING A QUICK REDUCTION IN GAS PRESSURE IN THE WORKING CHAMBER WITH A RELATIVELY SLOWER DISCHARGE OF GAS FROM THE ACCUMULATORS INTO A GAS STORAGE TANK.
