Abstract: A scroll compressor is provided that may include an orbiting scroll having an orbiting wrap, and which performs an orbiting motion; and a fixed scroll having a fixed wrap to form a compression chamber including a suction chamber, an intermediate pressure chamber, and a discharge chamber, by being engaged with the orbiting wrap. In a state in which the orbiting scroll and the fixed scroll are concentric with each other, when a distance between the orbiting wrap and the fixed wrap is defined as an orbiting radius, there exists an offset section having an interval larger than the orbiting radius, between a side surface of the orbiting wrap and a side surface of the fixed wrap which faces the orbiting wrap. With such a configuration, even if the fixed scroll or the orbiting scroll is transformed due to thermal expansion, interference between the fixed wrap and the orbiting wrap at a portion having a large transformation amount may be prevented. This may prevent a frictional loss or abrasion between the fixed wrap and the orbiting wrap. Further, this may restrict or minimize a gap between the fixed wrap and the orbiting wrap at an opposite side to the suction chamber, resulting in enhanced compression efficiency.

Abstract: A scroll compressor is provided that may include a first wrap, and a second wrap engaged with the first wrap and coupled to be eccentric to a center of rotation of a rotational shaft to form a compression chamber, moving toward a central portion, together with the first wrap while performing an orbiting motion with respect to the first wrap. A height of at least one of the first wrap or the second wrap may be formed to have at least two inclination machining amounts which decrease toward the central portion, and the inclination machining amount of the central portion may be larger than the inclination machining amount of an edge portion or a wrap rigidity at a specific section, thereby preventing frictional loss or abrasion of the wrap and breakage of the wrap.

Abstract: A scroll compressor is provided that may include a casing; a drive motor provided at an inner space of the casing; a rotational shaft coupled to a rotor of the drive motor, and rotated together with the rotor; a frame provided below the drive motor; a fixed scroll provided below the frame, and having a fixed wrap; and an orbiting scroll provided between the frame and the fixed scroll, having an orbiting wrap se as to form a compression chamber including a suction chamber, an intermediate pressure chamber, and a discharge chamber, by being engaged with the fixed wrap, and having a rotational shaft coupling portion that couples the rotational shaft thereto in a penetrating manner. In a state in which a center of the fixed scroll and a center of the orbiting scroll are substantially the same, an interval between the fixed wrap and the orbiting wrap gradually increases towards the suction chamber from the discharge chamber.

Abstract: A scroll compressor is provided that may include a casing; an electric motor drive having a stator fixed within the casing, and a rotor rotatably provided within the stator; a rotational shaft coupled to the rotor to rotate along with the rotor; a compression device disposed at a lower portion of the electric motor drive to receive a rotational force from the rotational shaft and compress a refrigerant; and an oil storage space located within the casing. A plurality of oil discharge paths to allow oil accumulated at an upper portion thereof to be discharged to the oil storage space may be formed on an outer circumferential surface of the compression device to be separated from each other, and an overall cross-sectional area of the plurality of oil discharge paths may be about 2 to about 12% of an inner diameter cross-sectional area of the casing brought into contact with or separated from an outer circumferential surface of the compression device in the compression device.

IPC: F04C18/02
Abstract: A scroll compressor includes a casing, a drive motor arranged in an inner space of the casing, a rotary shaft coupled to the drive motor to rotate, a main frame arranged under the drive motor, a fixed scroll arranged under the main frame, an orbiting scroll engaging with the orbiting scroll to make an orbiting motion, the rotary shaft being inserted into and eccentrically coupled to the orbiting scroll, a first bearing positioned between the main frame and the rotary shaft, and a second bearing positioned between the fixed scroll and the rotary shaft, where a gap between the first and second bearings and the rotary shaft varies with a vertical position. The scroll compressor may prevent the eccentric effect occurring during rotation from deteriorating performance of the bearings, thereby preventing compression performance from being lowered.
