Description
本実施形態の圧縮機は、図1および図2に示すように、いわゆる回転ピストン型のロータリー圧縮機(1)で構成されている(以下、単に「圧縮機」という)。この圧縮機(1)は、ドーム型のケーシング(10)内に、圧縮機構(20)と該圧縮機構(20)を駆動する電動機(30)とが収納され、全密閉型に構成されている。また、この圧縮機(1)は、電動機(30)がインバータ制御されて容量が段階的または連続的に可変となる可変容量型の圧縮機に構成されている。そして、この圧縮機(1)は、電動機(30)によって圧縮機構(20)を駆動することにより、例えば、冷媒を吸入、圧縮した後に吐出して冷媒回路内で循環させるものである。
次に、上述した圧縮機(1)の運転動作について説明する。
以上説明したように、本実施形態によれば、吐出口(29)の入口(29a)の開口面積S0、リード弁(41)の最大リフト時における弁突起部(41b)と吐出口(29)との間に形成される流路の最小断面積S1およびリード弁(41)の最大リフト時における弁平板部(41a)とシート部(22b)との間に形成される流路の最小断面積S2が、S2≧S1≧S0の関係を満たすように吐出口(29)の形状およびリード弁(41)の形状を形成するようにしたので、圧縮室(25b)の冷媒が吐出口(29)の入口(29a)から流入してシート部(22b)と弁平板部(41a)との間隙を通過するまでの間、一度も流量を絞ることなく流すことができる。したがって、冷媒の流速が増大して流動抵抗の影響をより受ける高速運転時において、流路面積減少による流動抵抗の発生を防止できる。これにより、吐出圧力損失を効果的に低減することができる。
本発明は、上記実施形態について、以下のような構成としてもよい。
20 圧縮機構
22b シート部
29 吐出口
29a 入口
29b 出口
41 リード弁
41a 弁平板部
41b 弁突起部
