Abstract

【課題】　リリーフ弁機能を備えた可変容量圧縮機の容量制御弁を提供する。また、基本構成を変えずに、吸入室圧力制御特性を、吐出室圧力が上昇すると制御吸入室圧力が低下する特性、吐出室圧力が上昇すると制御吸入室圧力が上昇する特性、吐出室圧力の変化が制御吸入室圧力に殆ど影響しない特性の何れにも設定できる、可変容量圧縮機の容量制御弁を提供する。 【解決手段】　傾角可変の斜板要素１０７を含む可変容量圧縮機１００の吐出室１２０とクランク室１０５とを連通させる連通路１２１を開閉して吐出容量制御を行う可変容量圧縮機１００の容量制御弁２００であって、一端が吐出室１２０に連通し他端が弁室２１１ｂに開口する弁孔２１１ｃと、クランク室１０５に連通する弁室２１１ｂに配設され弁孔２１１ｃを開閉する弁体２１２と、弁室２１１ｂに配設され弁体２１２を閉弁方向へ付勢する第１バネ２１３と、バルブハウジング２１１に形成されたガイド孔２１１ｄに挿通され、弁孔２１１ｃに進入した一端部が弁体２１２に当接可能であり、弁孔２１１ｃから遮断された圧力室２１６に他端部が進入した伝達ロッド２１５と、圧力室２１６に配設され伝達ロッド２１５の他端部を第１バネ２１３に対向して弁体２１２へ向けて付勢する第２バネ２１８と、第１バネ２１３の付勢力と第２バネ２１８の付勢力とを受けて弁体２１２と伝達ロッド２１５とが一体化した弁体伝達ロッド組立体を付勢して弁体２１２を駆動し弁孔２１１ｃを開閉制御する弁駆動手段２２０とを備える。
