Problems solved by technology

Such mounting of the electric motor complicates the assembly of the scroll compressor and thus increases the manufacturing cost of the scroll compressor
[0008] In addition, in order to ensure effective cooling of the electric motor, in particular of the first and second stator end windings of the stator of the electric motor, the presence of the inner casing necessitates the provision of specific flow channels on the inner casing and / or the provision of support for the drive shaft The support element at the lower end of the scroll compressor further increases the manufacturing cost of the scroll compressor

Embodiment Construction

[0055] figure 1 The scroll compressor 2 is shown in a vertical position. However, the scroll compressor 2 according to the present invention can be in an inclined position or a horizontal position without significant modification of its structure.

[0056] The scroll compressor 2 includes a hermetic casing 3 including a middle casing 4 , an upper cover 5 and a lower cover 6 . The intermediate housing 4 is substantially cylindrical and may have a constant outer diameter over the entire length of the intermediate housing 4 or a variable outer diameter along the length of the intermediate housing 4 .

[0057] The scroll compressor 2 also includes a suction port 7 configured to supply the scroll compressor 2 with refrigerant to be compressed, and a discharge port 8 configured to discharge the compressed refrigerant. Advantageously, the suction port 7 is provided on the middle housing 4 , while the discharge port 8 is provided on the upper cover 5 .

Abstract

The scroll compressor (2) includes a hermetic casing (3) comprising a mid shell (4) provided with a suction inlet (7); a compression unit (11) arranged within the hermetic casing (3); a drive shaft (27) configured to drive an orbiting scroll (13) of the compression unit (11); an electric motor (21) coupled to the drive shaft (27) and configured to drive in rotation the drive shaft (27) about its rotational axis, the electric motor (21) including a rotor (22) and a stator (23) which includes a stator stack (24), wherein the stator stack (24) is press-fitted in the mid shell (4), the suction inlet (7) is facing the stator stack (24), and the compression unit (11) includes a single suction opening (34) arranged at an opposite position in relation to the suction inlet (7).

Description

technical field [0001] The invention relates to a scroll compressor, in particular to a scroll refrigeration compressor. Background technique [0002] As we all know, scroll compressors include: [0003] - a hermetic casing comprising an intermediate casing provided with a suction inlet configured to supply the scroll compressor with refrigerant to be compressed; [0004] - a compression unit arranged in the airtight housing and configured to compress the refrigerant supplied by the suction port; [0005] - a drive shaft configured to drive an orbiting scroll of the compression unit in orbital movement, the drive shaft being rotatable about an axis of rotation; [0006] - An electric motor coupled to the drive shaft and configured to drive the drive shaft in rotation about an axis of rotation, the electric motor comprising a rotor and a stator arranged around the rotor. [0007] The electric motor of such a scroll compressor is generally arranged in an inner housing fixed...
