Abstract

The scroll compressor of the present invention includes: a main casing having a suction port for sucking refrigerant from the outside; a driving unit provided inside the main casing for generating rotational power; a scroll compression unit including an orbiting scroll and a fixed scroll, the orbiting scroll is rotated by rotational power transmitted via the drive unit and has helical rotating teeth, the The fixed scroll is engaged with the main housing to have a fixed position and includes helical fixed teeth that engage with helical rotating teeth; and a discharge housing that is engaged with the main housing and has a An inlet for receiving high-pressure refrigerant compressed in the scroll compression unit and a discharge port for discharging refrigerant received through the inlet. The discharge housing includes: a discharge passage formed spirally from the inlet and connected to an outlet formed on an outer circumference thereof outside; a communication passage along a direction connected to the discharge passage and a resonant cavity that is connected with the discharge channel through the communication channel and has an enlarged volume compared with the volume of the communication channel to reduce from Noise and pulsation of refrigerant discharged in the scroll compression unit.

Description

technical field

[0001] The present invention relates to a scroll compressor, and more particularly, to a scroll compressor capable of reducing noise and pulsation of discharged fluid. Background technique

[0002] In general, a scroll compressor is one that includes scroll teeth and compresses fluid using relative motion between a fixed scroll that is fixed regardless of the rotation of a drive shaft and an orbiting scroll that rotates with the rotation of a drive shaft. equipment.

[0003] As one of these scroll compressors, a scroll compressor having a sealing structure for a back pressure chamber disclosed in Korean Patent No. 0912515 includes: a casing, a drive unit for generating torque, a A suction unit that sucks fluid from the outside, a fixed scroll with a helical wrap for compressing the fluid sucked through the suction unit, an orbiting scroll with a helical wrap that meshes with the wrap of the fixed scroll The scroll compression unit and the discharge port thr...
