摘要： A balance weight to equilibrate an inertial force due to reciprocation of an Oldham's ring is mounted so that a vibration due to an unbalanced inertial force of the Oldham's ring is transmitted in a direction perpendicular to or almost perpendicular to a connecting direction between the closed vessel and the accumulator, whereby a vibration resulting from an unbalanced inertial force of the compressor body due to the balance weight to equilibrate the inertial force on account of the reciprocation of the Oldham's ring is increased in a direction perpendicular to or almost perpendicular to the connecting direction between the closed vessel and the accumulator. The vibration, however, is reduced in the connecting direction or in a direction close to the connecting direction. As a result, vibrations of pipes connecting the closed vessel to the accumulator are reduced, and reduction of noise of the overall air conditioning system is attained.

摘要： A compressor includes a communication hole 42 through which lubrication oil in an oil reservoir 5 is supplied to a back pressure chamber 39 at least through an eccentrically driving bearing 15, and a communication bore 45 or gap through which the lubrication oil in the back pressure chamber 39 is fed into compression spaces, and a constricted resistance member 44 for regulating the oil flow rate is provided on the communication hole 42. The passage resistance can be made larger in comparison with the case where resistance is caused in a small space of a sliding portion of a bearing, and an accurate value of the passage resistance can be preset with the oil flow rate being low, thereby preventing flow of the lubrication oil to the compression operating spaces from increasing in quantity. Thus, there is provided a highly reliable scroll compressor which has a high compression efficiency, consumes power constantly, and has no risk of compression of the lubrication oil in the compression operating spaces.

摘要： An outlet check valve includes an output valve seat provided at an outlet port or an outlet passage for compressed air in the vicinity of an outlet port of a compression mechanism and an outlet valve body. The valve seat and valve body are biased away from each other by a gravitational force or a spring. With this arrangement, even if a compressor is rotated at a low speed during a start-up operation, it is possible to cause stagnant liquid to undergo reverse flow into an accumulator disposed on the suction side and to store the liquid temporarily, thereby removing the liquid in the compression spaces and the suction passages and facilitating the start-up operation in a normal rotational direction. A pressure difference between the pressures upstream and downstream relative to the valve body is large when the normal rotating operation is stopped. By this pressure difference, the outlet valve body is moved to close the outlet valve seat, thereby to prevent the reverse rotation of the compression mechanism.

摘要： A swirling spiral impeller portion 13 is structured such that a pressure between the suction and discharge pressures acts on a part of the rear surface thereof. The compressor includes a means for adjusting and cooling the intermediate pressure which acts on a part of the swirling spiral impeller portion 13 by means of the lubricant oil stored in a lubricant oil reservoir 26 to which the discharge pressure in the sealed container acts. The lubricant oil supplied to the compression portion is provided under any pressure condition, and is always supplied stably. As the lubricant oil is cooled, it does not reduce the efficiency greatly.

摘要： In a scroll-type compressor, the revolving motion drive shaft 16, formed on the revolving end plate 12 at the side opposite to the revolving swirl blades 11, is fitted in an eccentric bearing eccentrically disposed inside of the main shaft of the crank shaft 6. The crank shaft 6 is connected to the rotor of the electric motor and is supported at the end portion thereof opposite to the main shaft by an upper bearing of a rolling type. Above the upper bearing, a rise preventing plate 24 for preventing the crank shaft 6 from excessively rising upwards is arranged in a fixed manner. The crank shaft 6 is so shaped as to have a stepped portion where the diameter of the shaft portion mounting the rotor 5 becomes stepwise greater than that of the shaft portion fitted in the upper bearing 21. Between the stepped portion and the inner race of the upper bearing 21 is provided an elastic member 26 which can be wave shaped. Between the rise preventing plate 24 and the end portion of the crank shaft 6 opposite to the main shaft of the crank shaft 6 a narrow clearance is maintained. By applying an elastic force of the elastic member 26 on the inner race of the upper bearing in the axial direction, abnormal noises from the bearing caused by axial vibrations and resonances of the shaft system can be prevented.

摘要： A scroll-type compressor has a crankshaft connected to the rotor of an electric motor for causing an orbiting motion of an orbiting scroll member and having a main shaft formed at one end thereof and supported by a main bearing, an orbiting drive shaft formed on the side of an orbiting end plate opposite to an orbiting scroll wrap and received in an eccentric bearing disposed at an eccentricity in the main shaft, a rolling type upper bearing supporting the end of the crankshaft opposite to the main shaft, and a lift limiting plate fixed to the lower surface of the upper bearing to prevent excessive lift of the crankshaft. A step is formed on the crankshaft between a portion of a greater diameter at which the crankshaft is connected to the rotor, and a portion of a smaller diameter at which the crankshaft is received in the upper bearing. The compressor further has a support member resting on the inner race of the upper bearing and a fixing member by which the crankshaft is suspended and supported from the support member such that a small clearance is left between the surface of the step of the crankshaft and the lift limiting plate. This configuration suppresses the generation of noise in the upper bearing attributable to axial vibration and resonance of the shaft system.

摘要： A linear compressor comprises a cylinder 10, a piston 20, a linear motor comprising a movable member 40 as well as a stationary member 50, a piston body 28, a discharge mechanism 60, a spring mechanism 70, a vessel 80, a supporting mechanism 90 and the like. A cylindrical holding member 41 is contact with a flange 24 connected to the piston and supported concentrically with the piston 20. A permanent magnet 42 is sandwiched between the cylindrical holding member 41 and a cylindrical body 43. Cylindrical inner yoke 51 and outer yoke 52 of the stationary member 50 are fixed to the cylinder 10, and held concentrically with the piston 20. With the above structure, the movable 40 is smoothly moved together with the piston 20, and a fine gap between the movable member 40 and the stationary member 50 is always maintained stationary. Further, since the linear motor is in contact with the piston 20, the overall length of the linear compressor is shortened, and the linear compressor is reduced in size. Therefore, it is possible to easily mount the movable member to the piston with high precision, and it is possible to easily mount the permanent magnet of the movable member with high precision.
