Document Type and Number:
WIPO Patent Application WO/2018/208024
Kind Code:
A1
Abstract:
A scroll compressor according to the present invention comprises: a casing in which the inner space is sealed; a driving motor which comprises a stator fixed in the inner space of the casing, and a rotor rotating inside the stator, and which is equipped with an inner passage and an outer passage which penetrate in the axial direction; a rotation shaft rotating by being coupled to the rotor of the driving motor; a compression part comprising a first scroll provided under the driving motor, and a second scroll which forms a compression chamber by being engaged with the first scroll, is eccentrically coupled such that the rotation shaft overlaps with the compression chamber in a radial direction, and performs a circling motion with respect to the first scroll, thereby allowing a refrigerant compressed in the compression chamber to be discharged toward the inner space of the casing; a discharge tube in communication with an upper space, of the inner space of the casing, formed above the driving motor; and an oil separation member which is provided between the driving motor and the discharge tube, and provided a space part having a depth on the upper surface to centrifugally separate oil from the refrigerant discharged from the compression part.
