According to one embodiment, a rotary compressor includes a compression mechanism unit and an electric motor. The compression mechanism unit includes a first bearing, a second bearing, first to third refrigerant compression units, a second intermediate partitioning panel, and a rotation shaft. The compression mechanism unit is fixed to the sealed container by a pair of fixing units which are provided at two locations spaced apart from each other in the axial direction of the rotation shaft, and the center of gravity of a structure comprising the compression mechanism unit and the rotor of the electric motor is positioned between the pair of fixing units.

Rotary compressor and refrigeration cycle apparatus

According to one embodiment, a rotary compressor accommodating an electric motor portion and a compression mechanism portion in a sealed case, wherein the compression mechanism portion comprises a cylinder, a roller, and a vane. The vane is disposed by stacking two divided vanes in a height direction of the cylinder, which is an axis direction of the rotation axis, and where a height dimension of one divided vane is H, and a minute gap between a height dimension of the cylinder and a height dimension of the two stacked divided vanes is L, a proportion of the minute gap L to the vane height dimension H per one divided vane is0.001&#x3c;/number of divided vanes/&#x3c;0.0015.

Rotary compressor and refrigerating cycle apparatus

In one embodiment, a compression mechanism unit of a rotary compressor includes a cylinder includes a cylinder chamber, a roller in the chamber, first and second vanes which come into contact with the roller and partition the chamber into a compression side and an absorption side, and a bias member which biases the vanes. On both end sides of a posterior end portion of the first vane, first vane side attachment portions having an equal dimension in the axial direction are provided. On both end sides of the second vane along the axial direction of the axis, second vane side attachment portions having an equal dimension in the axial direction are provided. The vanes are attached to the bias member via the attachment portions.
