Abstract: A scroll compressor is disclosed. A scroll compressor according to an embodiment of the present invention comprises: a compression part for discharging, to the inner space of a casing, a refrigerant compressed in a compression chamber; a discharge port for forming a flow path through which the refrigerant compressed in the compression chamber is discharged to the outside of the compression chamber; and a valve member, which has, at one end portion thereof, a root part fixed to a valve seat part of the compression part, forms a free end on the other end portion thereof, and has a head part to open/close the discharge port. A spacing part is provided between the head part of the valve member and the valve seat part to space the head part from the valve seat part in a state in which the compression part stops.

Abstract: A rotary compressor is provided that may include a cylinder having an inner circumferential surface with an annular shape to form a compression space; a roller having a plurality of vane slots disposed at predetermined intervals along an outer circumferential surface thereof, and rotatably inserted into the compression space of the cylinder; and a plurality of vanes slidably inserted into the respective vane slots to rotate together with the roller and by which the compression space is divided into a plurality of compression chambers. At least one of the vane slots is unequally spaced in a circumferential direction. Accordingly, periodicity of noise may be reduced to thereby increase the effect of noise reduction of the compressor.

Abstract: The present disclosure relates to a compressor including a branch part for reducing vibration and noise caused by a refrigerant flowing inside a muffler by expanding an enclosed space formed by a compression part and the muffler in the direction of a rotation axis.
