Abstract
Description
図1は、実施例1のロータリ圧縮機を示す縦断面図である。図2は、実施例1のロータリ圧縮機の圧縮部を示す分解斜視図である。
次に、実施例1のロータリ圧縮機1の特徴的な構成について説明する。実施例1の特徴には、アキュムレータ25のアキュムレータ容器26が含まれる。本実施例1において、圧縮機筐体10及びアキュムレータホルダ50は、鋼板等の金属材料によって形成されている。図1に示すように、アキュムレータ容器26は、樹脂材料によって形成された円筒状の胴部41と、金属材料によって形成されて胴部41の上端41aを塞ぐカップ状の上部42と、金属材料によって形成されて胴部41の下端41bを塞ぐカップ状の下部43と、を有する。
実施例1のロータリ圧縮機1において、圧縮機筐体10の外周面10aに固定されたアキュムレータ25のアキュムレータ容器26は、樹脂材料によって形成された筒状の胴部と、金属材料によって形成されて胴部の上端41aを塞ぐ上部42と、金属材料によって形成されて胴部41の下端41bを塞ぐ下部43と、を有し、胴部41の上端41aに上部42が接合され、胴部41の下端41bに下部43が接合されている。一般に、樹脂材料の縦弾性係数は金属材料の縦弾性係数の1/100未満であり、金属材料と比べて振動を伝え難い。このため、本実施例1によれば、金属材料と比べて制振性が高い樹脂材料によって形成されたアキュムレータ容器26を用いることが可能になり、鋼板によって形成されたアキュムレータ容器を備える構造と比べて、ロータリ圧縮機1の振動の発生を抑えて、振動に伴う騒音を減らすことができる。
実施例2によれば、実施例1と同様に、制振性が高い樹脂材料によって形成されたアキュムレータ容器226を用いることが可能になり、ロータリ圧縮機1の振動の発生を抑えて、振動に伴う騒音を減らすことができる。
実施例3によれば、実施例1、2と同様に、制振性が高い樹脂材料によって形成されたアキュムレータ容器326を用いることが可能になり、ロータリ圧縮機1の振動の発生を抑えて、振動に伴う騒音を減らすことができる。また、実施例3によれば、中間部49が支持板35を兼ねることで、実施例2における支持板35の取付け工程を省くことが可能になる。
