Abstract:	本研究建立膜片式往覆壓縮機之性能量測，與瞬時壓力波之訊號，用以協助壓縮機之開發。當設計良好時，進氣腔之壓縮波較平緩，排氣腔之膨脹波能提昇壓力，而產生順利排氣。當設計不當時缸壓與進排氣腔不協調，其進排氣閥開啟過早，而波動增劇，增加馬達之負載。參數之探討上以進排氣閥孔大小對其排氣壓力之影響最為直接、然而有一最佳之閥孔其效率最佳。而閥片形狀之改變，可控制流體在壓縮機內進出之時序，對壓縮機效率之改變最為明顯。以目前壓縮機尺寸，其最佳之進排氣閥孔直徑為8mm，並配合閥片頸寬10mm 有最佳之效率 A performance map and instantaneous pressure measurement were used to study the design parameters on the diaphragm reciprocating compressor. Under the design point, the compression wave in the intake chamber is weak, the expansion wave in the exhaust cham
