摘要： According to a compressor of the present invention, the compressor further comprises an oil separating mechanism 40 which separates oil from the refrigerant gas discharged from the compressing mechanism 10, the oil separating mechanism 40 includes a cylindrical space 41 in which the refrigerant gas orbits, an inflow portion 42 for flowing the refrigerant gas discharged from the compressing mechanism 10 into the cylindrical space 41, a sending-out port 43 for sending out, from the cylindrical space 41 to the one container space 32, the refrigerant gas from which the oil is separated, and an exhaust port 44 for discharging the separated oil from the cylindrical space 41 into the other container space 32. According to this configuration, efficiency of the electric motor 20 is enhanced, volumetric efficiency is enhanced, and low oil circulation is realized.

摘要： Impulsive sound of an Oldham ring is reduced and a driving noise of a scroll compressor is prevented from increasing. When a width of the key of the Oldham ring made of iron-based material is defined as t and a width of the orbiting-side key groove in the back surface of the surface plate of the orbiting scroll made of aluminum-based material and a width of the fixed-side key groove of the main bearing member made of aluminum-based material on the side of a thrust surface are defines as s, a gap d generated at s−t with respect to a key pitch L of the Oldham ring I set in a range of (6×10−5)≦d/L≦(3.5×10−4). With this, even if the key of the Oldham ring vibrates in the key groove, a collision force against the key groove is weakened, impulsive sound of the Oldham ring becomes small, and a driving noise of the scroll compressor is can be reduced.
摘要翻译：杜厄姆环的冲击声减少，并且防止涡旋压缩机的驾驶噪音增加。当由铁基材料制成的奥德姆环的键的宽度被定义为由铝基材料制成的绕动涡盘的表面的后表面中的绕轨侧键槽的宽度，以及在推力面一侧由铝基材料制成的主轴承构件的固定侧键槽的宽度定义为s，相对于奥德姆环I的键间距L在第st处产生的间隙d 在（6×10 -5）<= d / L <=（3.5×10 -4）的范围内。这样，即使键槽中的十字键的键振动，对键槽的碰撞力减弱，十字形环的冲击声变小，也能够减小涡旋压缩机的驱动噪音。

摘要： It is an object of the present invention to reduce impulsive sound of an Oldham ring and to prevent a driving noise of a scroll compressor from increasing.When a width of the key of the Oldham ring 57 made of iron-based material is defined as t and a width of the orbiting-side key groove 19 in the back surface of the surface plate 12a of the orbiting scroll 12 made of aluminum-based material and a width of the fixed-side key groove 32 of the main bearing member 51 made of aluminum-based material on the side of a thrust surface are defined as s, a gap d generated at s−t with respect to a key pitch L of the Oldham ring 57 is set in a range of (6×10−5)≦d/L≦(3.5×10−4). With this, even if the key of the Oldham ring 57 vibrates in the key groove, a collision force against the key groove is weakened, impulsive sound of the Oldham ring becomes small, and a driving noise of the scroll compressor is can be reduced.

摘要： A crankshaft directly connected to an electric motor and operably connected to a drive load is supported at two locations with bearings that are respectively subject to different amount of bearing loads. A resilient member is interposed between the inner race of one or both of the bearings and the crankshaft for applying an axial pre-load to the bearings. The weight of the crankshaft and the rotor, and/or a magnetic attractive force generated in the electric motor is/are applied to the bearing as an axial pre-load in addition to the pre-load by the resilient member.
