Abstract: A scroll compressor includes a casing, and an internal sealed space in the casing; a drive motor configured with a stator and a rotor which rotates within the stator, and that has an internal flow passage and an external flow passage; a rotation shaft connected to the rotor; a compression unit that includes a first scroll, and a second scroll which is engaged with the first scroll to form a compression chamber, with which the rotation shaft is eccentrically combined; a discharge pipe that communicates with an upper space of the internal space; an oil separation member disposed in the upper space; and a guidance member that is provided between an upper end of the drive motor and a lower end of the discharge pipe and guides the refrigerant with which the oil is mixed, to the oil separation member.

Abstract: A scroll compressor is provided that may include a casing that contains oil in a lower space thereof; a drive motor provided at a position spaced from an upper end of the casing by a predetermined gap, such that an upper space is formed in the casing; a rotational shaft coupled to a rotor of the drive motor, and having an oil supply passage to guide the oil contained in the casing to an upper side of the drive motor; a frame provided below the drive motor; a fixed scroll provided below the frame, and having a fixed wrap; an orbiting scroll provided between the frame and the fixed scroll, having an orbiting wrap so as to form a compression chamber by being engaged with the fixed wrap, and a rotational shaft coupling portion to couple the rotational shaft to the orbiting scroll in a penetrating manner; and an oil collection unit including an oil separator provided at the upper space of the casing, and an oil guide having a first end that communicates with the oil separator and a second end that communicates with a lower space of the fixed scroll.
