Description
。
記スプリングリード側に折曲形成したストッパ当接部を備えるストッパとを、この順で前記各保持部を重ねて前記バルブプレートの台座部に固定した構成とし、さらに、前記スプリングリードを、スプリングリード折曲部において前記可動部が弁座部側に折り曲げられ、該可動部の先端部が前記プレート当接部に当接する構成とし、さらに前記ストッパのストッパ当接部と前記バルブプレートに形成されたプレート当接部の間に所定の間隔を設け、前記吐出リードの開放動作により、該吐出リードの開閉部が前記スプリングリードの可動部に当接し、さらに、前記吐出リードと前記スプリングリードの当接状態において、該スプリングリードの先端部が、前記ストッパのストッパ当接部に当接する構成としたもので、起動時等に吐出リードとスプリングリードの間にオイルが介在し、吐出リードに過大な荷重がかった場合においても、前記吐出リード開閉部に対応する位置において前記吐出リードに対し隙間が形成されるので、オイル介在による吸着を断ち切り、またプレート当接部に当接した状態で隙間の距離が安定することで、吐出弁装置のバネ特性を安定化させることができ、エネルギ効率の高い安定した密閉型圧縮機を提供することができる。
図1は、本発明の実施の形態1における密閉型圧縮機の断面図、図2は、同実施の形態における密閉型圧縮機の平面図、図3は、同実施の形態における吐出弁装置の閉時の側面断面図、図4は、同実施の形態における吐出弁装置の分解図、図5は同実施の形態における吐出弁装置の開時の側面断面図、図6は、同実施の形態における吐出弁装置のバネ特性図である。
