Abstract

733,511. Fluid-pressure servomotor control systems. CARRIER ENGINEERING CO., Ltd. March 30, 1953 [Sept. 6, 1952], No. 8799/53. Class 135. In a system for controlling the capacity of a reciprocating compressor, more especially for refrigerating plant, as described in Specification 654,451, and comprising a valve 20 sensitive to compressor load as detected by intake pressure and controlling a distributing valve 16 which directs oil under pressure sequentially to spring- loaded pistons 39 associated with each cylinder and coacting with abutments 32 for holding open the compressor inlet valves, the response of the system to change of load is retarded by transmitting the intake pressure to the pressuresensitive element 63 of the valve 20 through a capillary tube 24 and surge chamber 23. The capillary tube opens to the compressor crankcase, which is at intake pressure, below the level of lubricating oil therein. The lower part of the surge chamber 23 contains oil and the upper part refrigerant gas.
