Abstract
According to a scroll compressor associated with the present disclosure, the entire cross-sectional area of bypass holes formed at a compression chamber with a larger volume reduction gradient between the both compression chambers may be formed to be larger than that of bypass holes at the other compression chamber to prevent over-compression at the compression chamber with a larger volume reduction gradient, thereby enhancing the entire efficiency of the compressor.
Claims12
A scroll compressor having both compression chambers with different volume reduction gradients, wherein the entire cross-sectional area of bypass holes formed at a compression chamber with a larger volume reduction gradient between the both compression chambers is formed to be larger than that of bypass holes at the other compression chamber.
A scroll compressor, comprising:
- a fixed scroll having a fixed wrap;
- a orbiting scroll tooth-coupled to the fixed wrap to have a orbiting wrap forming a first and a second compression chamber on an outer and an inner surface thereof, and a rotating shaft coupling portion is formed at a central portion thereof to perform orbiting movement with respect to the fixed scroll;
- a rotating shaft having an eccentric portion in which the eccentric portion is coupled to a rotating shaft coupling portion of the orbiting scroll to be overlapped with the orbiting wrap in a radial direction;
- and
- a driving unit configured to drive the rotating shaft,
- wherein bypass holes passing through the first and the second compression chamber to the outside are formed at the fixed scroll, and
- the entire cross-sectional area of bypass holes passing through the second compression chamber among the bypass holes is formed to be larger than that of bypass holes passing through the first compression chamber.
A scroll compressor formed with two pairs of compression chambers in which the two pairs of compression chambers are discharged through one discharge port, and bypass holes bypassing part of refrigerant prior to discharging refrigerant compressed in each compression chamber through the discharge port are formed at the each compression chamber,
- wherein the entire cross-sectional areas of bypass holes formed at the both compression chambers are different from each other.
