Title
(EN) COMPRESSOR
(FR) COMPRESSEUR
(JA) 圧縮機
Abstract
(EN)
Provided is a compressor having a structure that allows vacuuming work to be performed in the same way as before and that is able to suppress flow of liquid refrigerant and oil from an intake passage to the outside of the compressor. A compressor 100 is provided with a valve device 30 comprising a first regulation valve 40 and a second regulation valve 60 that regulate the degree of opening of an intake passage L11. The first regulation valve 40 regulates the degree of opening of a first passage 41, and the second regulation valve 60 regulates the degree of opening of a second passage 61 that branches off from the upstream area of the first passage 41 and that reaches an intake chamber H1. Biasing force for biasing a first valve body 44 of the first regulation valve 40 in a valve closing direction is set such that, when a differential pressure ΔP is less than a predetermined value C, the first valve body 44 closes the first passage 41. Biasing force for biasing a second valve body 62 of the second regulation valve 60 in a valve closing direction is set such that, when air collides with a reception surface 67, a valve-opened state in which the second valve body 62 opens the second passage 61 is maintained, and when the liquid refrigerant collides with the reception surface 67, the second valve body 62 closes the second passage 61.

L'invention concerne un compresseur présentant une structure permettant d'effectuer un fonctionnement de mise sous vide comme précédemment et pouvant supprimer l'écoulement de réfrigérant fluide et d'huile d'un passage d'admission vers l'extérieur du compresseur. Le compresseur (100) est muni d'un dispositif (30) à soupapes comprenant une première soupape de régulation (40) et une seconde soupape de régulation (60) destinées à réguler le degré d'ouverture d'un passage d'admission (L11). La première soupape de régulation (40) régule le degré d'ouverture d'un premier passage (41), et la seconde soupape de régulation (60) régule le degré d'ouverture d'un second passage (61) se bifurquant à partir de la zone amont du premier passage (41) et atteignant une chambre d'admission (H1). Une force de sollicitation, destinée à solliciter un premier corps (44) de la première soupape de régulation (40) dans une direction de fermeture de soupape, est réglée de sorte que, lorsqu'une différence de pression ΔΡ est inférieure à une valeur prédéfinie (C), le premier corps (44) de soupape ferme le premier passage (41). Une force de sollicitation, destinée à solliciter un second corps (62) de la seconde soupape de régulation (60) dans une direction de fermeture de soupape, est réglée de sorte que, lorsque l'air entre en collision avec une surface de réception (67), un état d'ouverture de soupape, dans lequel le second corps (62) de soupape ouvre le second passage (61), soit maintenu, et que, lorsque le réfrigérant fluide entre en collision avec la surface de réception (67), le second corps (62) de soupape ferme le second passage (61).

前記真空引き作業を従来と同様に行うことができると共に、液冷媒及びオイルの吸入通路から圧縮機外への流出を抑制可能な構造を備えた圧縮機を提供する。 圧縮機100は、吸入通路L11の開度を調整する第1調整弁40及び第2調整弁60からなる弁装置30を備える。第1調整弁40は第1通路41の開度を調整し、第2調整弁60は第1通路41の上流領域から分岐して吸入室H1に至る第2通路61の開度を調整する。第1調整弁40の第1弁体44を閉弁方向に付勢する付勢力は、差圧△Pが所定値Cより小さくなると、第1弁体44が第1通路41を閉止するように設定される。第2調整弁60の第2弁体62を開弁方向に付勢する付勢力は、空気が受け面67に衝突する場合、第2弁体62が第2通路61を開放する開弁状態を維持し、液冷媒が受け面67に衝突する場合、第2弁体62が第2通路61を閉止するように設定される。
