Claims (3)
- 吸入管(15)を保持しており、該吸入管の出口ノズル(15a)が内部へと開いており、該出口ノズル(15a)を通って気相および液相の少なくとも一方を含む冷媒流体の流れが内部へと吐き出される密閉シェル(10)と、
シェル(10)の内部に取り付けられ、バルブプレート(13)とヘッド(14)とによって閉じられた端部を有する圧縮室(CC)を定めているシリンダブロック(11)と、
シリンダブロック(11)へと取り付けられ、吸入管(15)へと向けられた入口ノズル(22)を備える導入管(21)と、圧縮室(CC)に連通した出口管(23)とを外部に備えている吸入マフラ(20)とを備える形式の冷凍圧縮機の吸入機構であって、
導入管(21)の入口ノズル(22)が、吸入管(15)の出口ノズル(15a)の輪郭の軸方向の投影に近接して該軸方向の投影の外側に設けられているとともに、出口ノズル(15a)の輪郭の軸方向の投影の軸に直交し、入口ノズル(22)の前方に位置する該軸方向の投影の領域に向かう方向(A)と、吸入管(15)の出口ノズル(15a)の輪郭の軸方向の投影の軸(X)に対して傾斜し、出口ノズル(15a)と入口ノズル(22)との間に画定される冷媒流体の流れが入るシェル(10)の内部領域に向かう方向(B)とのいずれか一方に向けられており、
入口ノズル(22)が、冷媒流体の流れに存在しうる気相を、入口ノズル(22)の内部の負圧の状態のもとで受け入れる一方で、冷媒流体の流れに存在しうる液相は、入口ノズル(22)の外部のシェル(10)の領域へと導かれることを特徴とする、前記吸入機構。 - 導入管(21)の入口ノズル(22)が、冷媒流体の流れの輪郭に接する輪郭を有することを特徴とする、請求項1に記載の吸入機構。
- 導入管(21)の入口ノズル(22)が、吸入管(15)の出口ノズル(15a)の輪郭の軸方向の投影に接する輪郭を有することを特徴とする、請求項1に記載の吸入機構。
