In order to prevent the rotating sleeve 26 from being separated from the central shaft 24 during rotation, the end of the central shaft 24 away from the connecting frame 23 extends out of the rotating sleeve 26, and the part of the central shaft 24 extending out of the rotating sleeve 26 is detachably connected with a limiting piece.
[0058] In addition, the utility model discloses a second aspect provides a kind of compressor comprising the horizontal liquid accumulator of any one embodiment described above. According to the compressor of the utility model embodiment, the sedimentation effect of liquid refrigerant can be effectively improved to reduce back liquid, effectively improve liquid knock and overcompression and other adverse phenomena, ensure the performance of compressor.
[0059] In the description of the utility model, it is understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "left", "right", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential" and the like are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and not to indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the utility model.
[0060] The above embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but can not therefore be understood as the limitation to the range of the utility model horizontal liquid accumulator and compressor. It should be pointed out that for ordinary skilled person in the art, under the premise of not departing from the utility model concept, several modifications and improvements can be made, which all belong to the protection range of the utility model.
