摘要： PROBLEM TO BE SOLVED: To adjust the capacity of a compresser in plural stages by comprising a group of the first and second compressing cylinders respectively composed of two compressing cylinders, and opening and closing the first and second cylinder passages communicated with the group of the first and second compressing cylinders by the unload valves. SOLUTION: When the first and second unload valves (hereinafter valve) 70, 80 are not energized, the coolant flown into an intake chamber 51 from an external, is taken into a cylinder through a partially opened communication port 72a and a valve chamber 54, and only one cylinder among four cylinders, is used. Then when the communication port 72a is opened by energizing only the first valve 70, the discharge pressure acting in the second discharging chamber, is acted on a piston 83, and the communication port 82a is completely closed, thereby only two cylinders are used. Further when only the second valve 80 is energized, three cylinders are used, and when the both valves 70, 80 are energized, four cylinders are used.

摘要： PROBLEM TO BE SOLVED: To prolong the life of connecting rod small end part bearings by respectively providing a needle bearing with a grease sealed type retainer on a low pressure side piston, and a grease sealed full type roller needle bearing on a high pressure side piston. SOLUTION: In a low pressure side cylinder, force is applied to the upper part of a small end part 4 at upward stroke of the piston 1. Force is applied to the lower part of the small end part 4 at downward stroke of the piston. At the dead point changing the direction of the alternate load, a piston pin 2 and a needle bearing 5 with a grease sealed type retainer are rotated in either direction. By repeating this action, the load receiving position is changed inch by inch, and lubricating grease is also averagely used on the full circumference. A grease sealed full type roller needle bearing 15 fitted to the piston 11 of a high pressure side cylinder is provided with the more number of needle rollers 15a so as to bear the higher load, and the needle rollers 15a are mutually contacted, rotated, and moved while pushing lubricating grease. Consequently, durability can be maintained.

摘要： PROBLEM TO BE SOLVED: To reduce a load when a load of an electric motor becomes large by detecting a load condition of the electric motor during operation. SOLUTION: Two-stage compression spaces to compress and deliver intake air by a piston-cylinder mechanism actuated by a common electric motor, are arranged by connecting a delivery port 4b of a front stage compression space 2 and an intake air port 5a of a rear stage compression space 3 to each other. In a two-stage compressor where a delivery port of the rear stage compression space 3 is connected to a compressed gas storage tank 7, an exhaust port is formed between the front stage compression space 2 and the rear stage compression space 3, and an electric current value of the electric motor or a terminal voltage value of the electric motor is detected by a detecting means. When the electric current value or the voltage value exceeds a prescribed value, a solenoid valve 16 of the exhaust port is opened, and intake air side pressure of the rear stage compression space 3 is reduced.

摘要： A multi-piston swash plate type compressor for an air-conditioning system used in a vehicle such as an automobile, including a cylinder block body having a swash plate chamber formed therein for receiving a swash plate and cylinder bores formed therein for receiving pistons which are reciprocated by rotation of the swash plate. The compressor has a suction chamber which is fed with a refrigerant including lubricating oil from an evaporator of the air-conditioning system and a discharge chamber which feeds the compressed refrigerant to a condenser of the air-conditioning system. When the compressed refrigerant is discharged from the cylinder bore into the discharge chamber through a discharge reed valve, all of the discharged refrigerant is impinged on the peripheral and inner wall so as to separate the lubricating oil from the refrigerant, whereby an effective damping and sealing oil layer is formed between the discharge reed valve and the valve seat thereof.
