摘要： PROBLEM TO BE SOLVED: To improve the durability of a connecting rod.
SOLUTION: A compression means 4 is formed of a pre-stage compressing part 11a and a post-stage compressing part 11b to compress carbon dioxide. A piston 41 of the compression means 4 is connected to the connecting rod 26, and the connecting rod 26 is connected to a crank 25 so that the piston reciprocates. At the time, in order to reduce abrasion of a connecting part of the piston 41 or the crank 25 to which the connecting rod 26 is connected due to great load from the piston 41, the connecting part is provided with a wear resisting part 49. To be concrete, the connecting rod 26 is formed of an aluminum-base alloy having a large quantity of silicon, whereby the strength of the connecting rod 26 itself can be improved, and the strength of the connecting part is improved to form the wear resisting part 49.

摘要： PROBLEM TO BE SOLVED: To reduce a motor load, prevent application of a large load to a connecting rod, and cool the motor in compressing carbon dioxide.
SOLUTION: A compression means 4 is formed of a pre-stage compressing part 11a and a post-stage compressing part 11b to compress carbon dioxide. A refrigerant introduction pipe 74 is provided to communicate a pre-stage discharge chamber 52 to which the refrigerant compressed by the pre-stage compressing part 11a is discharged with a motor chamber 18 for disposing the motor 2. The motor chamber 18 is communicated with a crank chamber 19 for storing a crank 25, and the crank chamber 19 and a post-stage intake chamber 53 are communicated with each other by a refrigerant return pipe 75. Thus, while the motor 2 is cooled, the pressure in the crank chamber 19 is made substantially equal to the pressure in the pre-stage discharge chamber 52 to reduce the load of the motor 2 and prevent application of a large load to the connecting rod 26 or the like.

摘要： PROBLEM TO BE SOLVED: To restrain increase of weight and cost by minimizing increase in thickness of a casing member or the like even in the case of compressing carbon dioxide.
SOLUTION: Two or more casing members are bolted and assembled through a sealing material to form a casing 5. In the casing 5, a pre-stage compressing part 11a and a post-stage compressing part 11b for compressing a carbon dioxide refrigerant are formed, and a motor 2 and cranks 25a, 25b for converting the rotary power of the motor 2 to the reciprocating power are stored in the closed state. At the time, a motor chamber 18 for storing the motor 2 and a crank chamber 19 for storing the cranks 25a, 25b are set lower than at least the pressure of a refrigerant discharged from the pre-stage compressing part 11a. Thus, the member constituting the casing 5 is reduced in thickness and weight.
