Abstract: PROBLEM TO BE SOLVED: To provide a refrigeration cycle of high reliability capable of preventing the seizure of a compressor even in poor lubricating sate and high load state of the compressor in the refrigeration cycle.
SOLUTION: In this refrigeration cycle comprising the compressor 1 for compressing and discharging a refrigerant, and having a refrigerant oil sealed in a refrigerant circulation passage for lubricating the compressor 1, fine particles 17 of approximately circular cross-section are mixed in the refrigerant circulating passage. Sliding faces of the compressor can be prevented from being directly kept into contact with each other by the fine particles 17 placed between the sliding faces. Further as the fine particles have the approximately circular cross-section, the fine particles 17 are rolled in relative movement of the sliding faces opposite to each other, thus the rolling friction is achieved. Accordingly, a coefficient of friction of a sliding part of the compressor 1 can be reduced.

Abstract: PROBLEM TO BE SOLVED: To prevent static slippage from occurring easily between a stator and a rotor and to reduce the minimum starting voltage for improving starting property, by setting the surface roughness of a stator slide surface for bringing the rotor into press contact slidably via a lining material to a value within a range between a specific lower-limit value and a specific upper-limit value. SOLUTION: A surface roughness of 10g on the upper surface (stator sliding surface) of a diaphragm part 20e of the outer periphery of a stator 10 is set to a range of 0.2-0.8 μm, and a piezoelectric element 12 is glued to the lower surface of the outer-periphery part of the stator 10 via a base ring 11. On the other hand, a lining material 16 made of a polyimide resin is glued to the lower surface of a stator contact part 1 5c being formed at the outer periphery of a rotor 15 being arranged on the upper surface of the stator 10. Then, when a high-frequency voltage of 220 V±10 V rms is applied to the piezoelectric element 12 for generating a traveling wave at a diaphragm part 10e, the rotor 15 is rotated by the traveling wave via the friction between the lining material 16 and a stator sliding surface 10g of the stator 10.

Abstract: PROBLEM TO BE SOLVED: To provide a power transmitting device with a constitution of good assembly workability without using a rolling ball whereby at overload time, a torque limiter function can be well displayed. SOLUTION: Mutually among a flange part 11a integrally molded in an inner side holding member 11, washer 13, circular arc-shaped protrusion part 7f in a flange part 7a of a hub 7, and a washer 14, by tension of a belleville spring 15, is friction engaged mutually into contact. In this way, when a compressor 4 is in ordinary operation, rotation of the inner side holding member 11 in a drive side is transmitted to a hub 7 and a rotary shaft 6 through a friction engaging mechanism. On the other hand, at overload time, between the washer 13 and the circular arc-shaped protrusion part 7f in a flange part 7a of the hub 7, which is a friction engaging surface decreasing a coefficient of friction, a slip is generated, by this slip, the washer 13 is dropped to come off in a notched recessed part of the hub 7, to be displaced in an axial direction of the rotary shaft 6, in this way, pressing force of the belleville spring 15 is reduced, the flange part 11a is raced.

Abstract: PROBLEM TO BE SOLVED: To stabilize cutoff torque for use at an overload in despite of a wide range of environmental temperature changes. SOLUTION: This power transmission device comprises a frictional engagement mechanism 7a, 11a, 13 to 16 for engaging a driving rotary member 1, 10, 11, 12 and a driven rotary member 7 with each other with frictional force. The frictional engagement mechanism uses an intermediate friction member 13 of graphite adapted to shear fracture when the transmission torque between both those rotary members reaches a set value. During normal operations of a compressor 4, this intermediate friction member 13 of the frictional engagement mechanism transmits the rotation of the driving rotary member 1, 10, 11, 12 to the driven rotary member 7. During overloaded operations of the compressor 4, meanwhile, this intermediate friction member 13 shears into fracture to set the driving rotary member 1, 10, 11, 12 idling.
