摘　　要：分析单螺杆式制冷压缩机常用滑阀结构的优缺点,指出目前滑阀结构在能量调节和内容积比调节方面存在的问题,提出一种通过实测压缩终了压力来调节内容积比的滑阀结构,该滑阀结构可以有效减小内外压比不等带来的不利影响。The advantages and disadvantages of the slide valve structure commonly used in single screw refrigeration compressor are analyzed,and the problems of slide valve structure existing in the respects of energy regulation and interior volume ratio regulation are pointed out.A slide valve structure to adjust the interior volume ratio by measuring the end pressure of compression is proposed,which can effectively reduce the adverse effects caused by the unequal internal and external pressure ratio.
