摘要:
A horizontally-mounted scroll compressor includes a first annular seal member (34,90,101,102,103,105) which is provided between a movable base plate and a slide-contact body (14,74) for sealing between a back-pressure region (61,82a) and a suction-pressure region (20,43,75,86). The first seal member has a plurality of first groove portions (34a-d) which connect the back-pressure region to the suction-pressure region. The shortest distance along a circumference of the first seal member between any two of the first groove portions which are the remotest from each other is set at not less than one-third of a circumferential length of the first seal member.
摘要:
A displacement control mechanism used for compressor is installed in a refrigerant circuit. The compressor has a bleed passage (27) and a supply passage (28). The displacement control mechanism includes a first control valve (CV1) and a second control valve (CV2). The first control valve (CV1) includes a first valve body (41) and a pressure sensitive member (54). The first valve body (41) adjusts the opening size of the supply passage (28). The pressure sensitive member (54) moves in accordance with a pressure in the refrigerant circuit. A pressure detection region (K) is located downstream of the first valve body (41). The second control valve (CV2) includes a second valve body (82). The second valve body (82) adjusts the opening size of the bleed passage (27). The second valve body (82) moves in accordance with the pressure of the pressure detection region (K). When the pressure of the pressure detection region (K) increases, the second control valve (CV2) decreases the opening size of the bleed passage (27). This permits to start with rapid cooling performance.
摘要:
A compressor (10) has a housing (11), a compression mechanism (35) and a partition member (60). The housing defines therein a discharge chamber (68). The compression mechanism (35) is located adjacent to the discharge chamber (68) in the housing (11). The partition member (60) faces a predetermined region, which is a portion of the compression mechanism (35) that faces the discharge chamber (68) except a specific region where a gas discharge port (37a) opens, for restraining pressure of refrigerant gas in the discharge chamber (68) to be applied to the predetermined region.
