A refrigerant circuit (11) includes an oil separator (60) configured to separate oil from high pressure refrigerant, and an oil feed circuit (70) configured to feed the oil separated in the oil separator (60) to a compression mechanism (20) so as to cool the refrigerant in the course of a compression phase of the compression mechanism (20). The oil feed circuit (70) includes a recovery mechanism (40) configured to recover energy of the oil separated in the oil separator (60). In the compression mechanism (20), the refrigerant is cooled by the oil, thereby reducing power of the compression mechanism (20). Simultaneously, in the recovery mechanism (40), power required to increase pressure of the oil in the compression mechanism (20) is recovered.

A rotary compressor includes a cylinder having an annular cylinder space, a piston eccentrically disposed relative to the cylinder, and a drive shaft (53) connected to the piston. The piston has a piston portion eccentrically rotatable relative to the cylinder, and a piston end plate closing the cylinder space. The cylinder has an end plate storage space storing the piston end plate in an eccentrically rotatable manner. The cylinder space forms a main cylinder chamber, and the end plate storage space forms a sub-cylinder chamber.

There is a need to provide a high-frequency power amplifier capable of reducing a talk current and reducing a phase deviation in output. The high-frequency power amplifier includes differently sized first through fifth power amplification transistors and impedance matching circuits for example. The high-frequency power amplifier changes a signal path to be used in accordance with a power specification signal. The high-frequency power amplifier uses a signal path from the first transistor to the second transistor in high power mode. The high-frequency power amplifier uses a signal path from the first transistor to the third transistor in medium power mode. The high-frequency power amplifier uses a signal path from the fourth transistor to the fifth transistor in low power mode. The high-frequency power amplifier is configured so that each of the signal paths includes the same number of stages of power amplification transistors and impedance matching circuits.
