    • A method and system for providing a ride-through reserve for a pulse tube refrigerator (PTR) (12) includes a pressurized tank (42) containing a fluid used to provide fluid pressure and auxiliary power to a PTR (12) during an electrical power supply failure. A pressure regulation valve (pressure valve) (44) releases the fluid from the pressurized tank (42) into the PTR (12). A power regulation valve (power valve) releases from the pressurized tank (12) a driving gas volume for driving a pneumatic motor (46). The pneumatic motor (46) in turn drives a rotary valve (22) of the PTR (12). A release valve (50) releases fluid from the PTR (12) so as to lower the fluid pressure to a predetermined pressure range and enable fluid oscillation in the PTR (12).
    • 一种用于为脉冲管制冷器(PTR)提供穿越储备的方法和系统包括加压罐(42),其在电力期间包含用于向PTR(12)提供流体压力和辅助动力的流体 供应故障。 压力调节阀(压力阀)(44)将流体从加压罐(42)释放到PTR(12)中。 功率调节阀(动力阀)从加压罐(12)释放用于驱动气动马达(46)的驱动气体体积。 气动马达(46)又驱动PTR(12)的旋转阀(22)。 释放阀(50)从PTR(12)释放流体,以将流体压力降低到预定压力范围,并使得PTR(12)中的流体振荡。
