Abstract: A compressor is provided. The compressor may include a fixed wrap, and an orbiting scroll having an orbiting wrap engaged with the fixed wrap to form compression chambers. The fixed wrap and the orbiting wrap may have irregular wrap curves. At least one interference avoiding portion at which a spacing between the wraps is greater than an orbiting radius or at least one gap compensating portion at which the spacing between the wraps is smaller than the orbiting radius, in a state in which a center of the fixed scroll and a center of the orbiting scroll are aligned with each other, may be provided on a sidewall surface of the fixed wrap or the orbiting wrap, whereby frictional loss or abrasion due to interference between the wraps or a refrigerant leakage due to a gap between the wraps may be prevented.

Abstract: A compressor includes a driving motor, a centrifugation space, a discharge pipe, a rotary shaft, a compression portion, a pump assembly, and an oil pickup. The centrifugation space is defined inside a case by a downstream side of the driving motor and the case, and enables centrifugation of a compressed refrigerant and a lubricant oil. The discharge pipe can discharge the refrigerant from the centrifugation space outside the case. The rotary shaft is coupled to a rotor of the driving motor and defines an oil supply path. The compression portion is provided at an upstream side of the driving motor and can compress the refrigerant as the rotary shaft rotates. The pump assembly is provided below the rotary shaft and can pump oil as rotated with the rotary shaft. The oil pickup defines an oil supply path between the pump assembly and a low oil space formed inside the case.

Abstract: A compressor, more particularly, a scroll compressor provides structures that may enhance centrifugal stiffness at a contact point between a fixed scroll and an orbiting scroll. The compressor may include an orbiting scroll having an orbiting scroll wrap wound around a radial-direction inner area from a radial-direction outer area; and a fixed scroll having a fixed scroll wrap wound around the radial-direction inner area from the radial-direction outer area. A surfacing part may be configured to narrow a distance between the orbiting scroll wrap and the fixed scroll wrap may be formed in a predetermined section of the orbiting scroll or fixed scroll wrap.

Abstract: Provided is a scroll compressor. The scroll compressor may be provided with at least one refrigerant accommodating groove recessed to a preset depth in at least one from a side surface of a fixed wrap constituting a compression chamber and a side surface of an orbiting wrap. Thus, a volume of the compression chamber in a discharge area may be increased in correspondence with a volume of the at least one refrigerant accommodating groove, and a space into which liquid refrigerant, etc. may escape may be ensured to resolve excessive compression in the compression chamber. Then, a stress exerted on the fixed wrap is reduced, and a damage to the fixed wrap due to pressure in the compression chamber may be suppressed.

Abstract: A scroll compressor includes a flow path guide disposed between a motor unit and a compression unit to separate a refrigerant flow path and an oil flow path. A guide discharge hole communicating with a discharge passage of the compression unit is formed axially through the flow path guide and a guide passage communicating with the guide discharge hole is annularly defined, such that a discharge guide protrusion surrounding the guide discharge hole extends toward the motor unit. Accordingly, inner and outer spaces of the flow path guide can communicate with each other while the refrigerant flow path and the oil flow path are separated, which results in securing a space of an oil recovery passage to allow quick oil recovery and simplifying a structure of the flow path guide to reduce manufacturing costs.
