PURPOSE:To heighten the efficiency of a closed cycle air systym by utilizing a gear compressor and a gear motor which change the speed steplessly by a pulse- like input/output adjusting method. CONSTITUTION:Load of a gear compressor 1 is adjusted by a pulse bypass valve, and a high-pressure system is operated by gear motors 5, 6, whereby high-pressure gas is stopped pulse-like in quick cycle by pulse stop valves 9, 10. Thus, the valves for bypassing and stopping in quick cycle are disposed so that speed change operation can be performed without loss. |
