4. The scroll compressor of claim 3, wherein an oil collecting through hole is penetratingly formed at the guide member so as to communicate the second inner space to the guide space.
5. The scroll compressor of claim 2, wherein the separation member is provided with an inlet and an outlet, and a sectional area of the inlet is different from a sectional area of the outlet.
6. The scroll compressor of claim 5, wherein the separation member is formed such that a sectional area of the outlet is smaller than a sectional area of the inlet.
7. The scroll compressor of claim 1, further comprising an oil recollection chamber located in the first inner space, wherein oil separated from the refrigerant within the second inner space is collected by gravity in the oil recollection chamber for reuse by the compressor.
8. The scroll compressor of claim 7, further comprising an oil collecting pipe in communication with the second inner space, wherein oil is separated from the refrigerant by gravity within the second inner space and drains therefrom through the oil collecting pipe to the oil recollection chamber for reuse.
9. The scroll compressor of claim 8, further comprising a capillary tube disposed on the oil collecting pipe.
10. A scroll compressor, comprising:
a casing having a first inner space and a second inner space, and having a discharge pipe connected to the second inner space;
a frame fixed between the first inner space and the second inner space of the casing;
a driving motor fixed to an inner circumferential surface of the casing in a forcible insertion manner so as to be disposed at the first inner space of the casing;
a fixed scroll fixedly-coupled to another side of the frame so as to be disposed at the second inner space of the casing, having a spiral-shaped fixing wrap for forming a compression chamber on one side surface thereof, having a discharge port penetratingly formed on another side surface thereof so as to discharge a compressed refrigerant from the compression chamber to the second inner space of the casing;
an orbiting scroll installed between the frame and the fixed scroll, having a spiral-shaped orbiting wrap engaged with the fixing wrap of the fixed scroll on one side surface thereof, and configured to form a pair of compression chambers together with the fixed scroll while performing an orbit motion as another side surface thereof is eccentrically coupled to a crank shaft of the driving motor, the two compression chambers to consecutively move together with the fixed scroll;
a check valve installed at an end of the discharge port of the fixed scroll;
a guide member having a guide space for accommodating the check valve, having one side fixed to the fixed scroll and another side fixed to an inner circumferential surface of the casing, and configured to guide a refrigerant discharged from the compression chamber through the discharge port to the driving motor; and
