According to one embodiment, a horizontal compressor comprises a container accommodating a compression mechanism unit and an electric motor unit, a first leg fixed to the container near the motor unit, a second leg fixed to an end of the container on the compression mechanism unit side, an accumulator between the legs, and a joint port in the container. The second leg includes a first support portion supporting the container in a horizontal attitude, and a second support portion supporting the container standing in a vertical attitude. The first support portion extends in a direction away from the joint port relative to the second support portion.

Horizontal compressor and refrigeration cycle system

A helical-blade fluid machine maintains a low-pressure atmosphere in a closed casing ( ) and secures a proper lubrication state for a compression mechanism ( ). The fluid machine has a drive mechanism ( ) that is installed at an upper or lower part of the casing and consists of a stator ( ) and a rotor ( ). The compression mechanism is installed at the other part of the casing. The compression mechanism has a cylinder ( ) and a roller ( ), which is swayed with respect to the cylinder by the drive mechanism. A helical blade ( ) having unequal pitches is arranged on the roller, to define compression chambers ( ). This arrangement lowers the head of lubricant. An intake pipe ( ) feeds gas into the casing so that a low-pressure atmosphere fills the casing.

Helical-blade fluid machine

A helical blade type compressor comprising a case, a cylindrical cylinder provided in the case, a roller disposed in the cylinder, and helical blades of uneven pitches for dividing a compression chamber so that the volume may be gradually smaller in the axial direction between the cylinder and roller, by revolving the cylinder and roller to move the compression chamber in the volume decreasing direction, thereby compressing the air, wherein at least one seal member is provided in the roller for separating into pressure in the case and the pressure in the compression chamber.

A helical-blade fluid machine maintains a low-pressure atmosphere in a closed casing (1) and secures a proper lubrication state for a compression mechanism (9). The fluid machine has a drive mechanism (7) that is installed at an upper or lower part of the casing and consists of a stator (11) and a rotor (15). The compression mechanism is installed at the other part of the casing. The compression mechanism has a cylinder (23) and a roller (25), which is swayed with respect to the cylinder by the drive mechanism. A helical blade (39) having unequal pitches is arranged on the roller, to define compression chambers (41). This arrangement lowers the head of lubricant. An intake pipe (5) feeds gas into the casing so that a low-pressure atmosphere fills the casing.

A rolling-piston expander has a hermetic casing 7 provided with a suction pipe 3 and a discharge pipe 5, a cylinder 13 disposed in the casing, a roller 31 eccentrically rotated in the cylinder, an expansion chamber 39 defined by the roller and communicating with a suction port 47 and a discharge port 55, a shaft 19 for supporting the roller so that the roller may eccentrically rotate, a suction timing controller 51 consisting of the ports 47 and 51, for controlling the timing of the supply of gas into the expansion chamber, and a bypass for supplying high-pressure gas into the expansion chamber when the suction timing is off.

Rolling-piston expander apparatus

In a scroll type compressor, a revolving scroll having a disc portion and a blade portion is engaged with a stationary scroll having a disc portion and a blade portion. A gas is introduced from the outer peripheral portions of these scrolls and compressed in a pair of compression chambers defined between the scrolls, and a compressed gas is discharged. A first inlet and a second inlet, which are connected by a communication path, are formed at positions corresponding to the compression chambers, where the gas is compressed. Release means is provided between one of the compression chambers and a gas suction unit. The release means returns part of the gas in one of the compression chambers directly to, and part of the gas in the other compression chamber via the first and second inlets, the communication path and the one of the compression chambers to, the gas suction unit simultaneously by equal degrees.
