    Abstract: A compressor, characterized in that a steel is used as the base material for the other sliding material vane 10 and nitrided, a CrN or DLC film is formed on the surface by PVD treatment, and a Ni-Cr-Mo cast iron is used for the other corresponding sliding material piston 9. It is possible in such a configuration to suppress the temperature rise by sliding friction of the sliding materials, such as the vane tip region 10a and the peripheral region of the piston 9 that are vigorously slid, relax decomposition of the refrigerant, and suppress corrosion by hydrogen fluoride generated in reaction with water and oxygen, and thus to provide a compressor higher in reliability.

    Abstract: It was found that a refrigerant mainly containing a carbon-carbon double bond-containing hydrofluoroolefin has a function to suppress abrasive wear, compared to conventional HFC-based refrigerants, because the hydrofluoroolefin generates iron fluoride especially on the surface of the vane and piston, where sliding force is severe, from hydrogen fluoride, even if it is generated in reaction with water and oxygen. It is possible to reduce abrasive wear, by using a refrigerant containing as the base component a hydrofluoroolefin as operating refrigerant and a refrigeration oil 3 miscible with the refrigerant and a vane 10 made of a high-speed tool steel and sintered and quenched, because hydrogen fluoride generated by decomposition of the refrigerant in the region of a vane tip region 10a and a piston 9 peripheral surface, where sliding force is severe is converted to iron fluoride. It is also possible to obtain a hardened structure containing carbides of W, Mo, Cr and V dispersed in a fine martensite matrix and produces the rotary compressor more cost-effectively by quenching and sintering the vane 10.

    Abstract: Disclosed is a rotary compressor provided with: a cylinder (30); an eccentric part (31a) of a shaft (31), said eccentric part being disposed inside the cylinder (30); a piston (32) that is fitted around the eccentric part (31a) and has a cylindrical groove (32a) formed therein, the arc angle of said groove being greater than 180°; the piston (32), inserted in a slot formed in the cylinder (30); a slot (30b) provided in the cylinder (30); the groove (32a) provided in the piston (32); and a vane (33) having a cylindrical part (33a) provided on one end thereof. A compression chamber (39) is formed between the cylinder (30) and the piston (32). The cylindrical part (33a) fits into the groove (32a) so as to be able to swing freely. As the shaft (31) rotates, the vane (33) moves back and forth inside the slot (30b). The compression chamber (39) is partitioned by the vane (33) into a high-pressure-side space (39b) and a low-pressure-side space (39a). The groove (32a) provided in the piston (32) is formed in a cylindrical shape having an arc angle greater than 180°. The imaginary extension line (La) of the arc is located inwards of the imaginary outer circumference line (Lb) of the piston (32). Thus it is difficult for gas or oil to leak from the high-pressure-side space (39b) of the compression chamber (39) to the low-pressure-side space (39a).

    Abstract: A rotary compressor includes a cylinder 30, an eccentric portion 31a of a shaft 31 disposed in the cylinder 30, and a piston 32 which is fitted into the eccentric portion 31a. A columnar groove 32a is formed in the piston 32, and angle of an arc of the groove 32a is greater than 180°. The rotary compressor further includes a piston 32 inserted into a slot formed in the cylinder 30, a slot 30b formed in the cylinder 30, and the groove 32a formed in the piston 32, and a columnar portion 33a having a columnar portion 33a on its one end. A compression chamber 39 is formed between the cylinder 30 and the piston 32, the columnar portion 33a is swingably fitted into the groove 32a, and the vane 33 reciprocates in the slot 30b as the shaft 31 rotates. The compression chamber 39 is divided into a high pressure-side space 39b and a low pressure-side space 39a by the vane 33. The groove 32a formed in the piston 32 is formed into a columnar shape, the groove 32a has the arc and an angle of the arc is greater than 180°. A fictitious extension La of the arc is located inside of the outer periphery fictitious line Lb of the piston 32. Gas and oil are less prone to leak from the high pressure-side space 39b to the low pressure-side space 39a of the compression chamber 39.

    Abstract: To solve the conventional problems, according to a rotary compressor of the present invention, a second area surrounded by a lower inner surface angle portion which is formed on a lower end surface of the piston 32 and the end plate 35 which closes the lower end surface of the cylinder 30 is set greater than a first area surrounded by an upper inner surface angle portion which is formed on an upper end surface of the piston 32 and the end plate 34 which closes the upper end surface of the cylinder 30, and an angle formed between the lower end surface of the piston 32 and the lower inner surface angle portion is set smaller than an angle formed between the upper end surface of the piston 32 and the upper inner surface angle portion. According to this configuration, it is possible to reliably retain oil on lower end surface of the piston 32, enhance the reliability, float the piston 32 even if a range of tolerances is increased, and enhance efficiency and productivity of the rotary compressor.
