摘要： A scroll compressor has a closed vessel in which a compression mechanism having orbiting and stationary scroll elements in engagement with each other is accommodated. A crankshaft is coupled with the orbiting scroll element and rotatably supported by a crank bearing. The crankshaft is rotated by an electric motor having a stator and a rotor so that the orbiting scroll element may orbit relative to the stationary scroll element. A plurality of balance weights are provided for maintaining static and dynamic balances of rotary elements including the orbiting scroll element, the crankshaft, and the rotor. The static and dynamic balances are calculated using at least a clearance between the crankshaft and the crank bearing.

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： An electrically-driven closed scroll compressor has a compression mechanism accommodated in a closed vessel. The compression mechanism includes a bearing member securely mounted in the closed vessel, a stationary scroll having a stationary scroll wrap formed thereon, an orbiting scroll having an orbiting end plate and an orbiting scroll wrap formed on the orbiting end plate so as to engage with the stationary scroll wrap to define a plurality of working pockets therebetween, and an eccentric bearing for allowing the orbiting scroll to undergo an orbiting motion relative to the stationary scroll. A generally ring-shaped sealing member is mounted on the bearing member so as to be held in contact with the orbiting end plate. The sealing member may be mounted on the orbiting end plate. The orbiting end plate has first and second regions defined therein internally and externally of the sealing member, respectively, so that the first and second regions may receive first and second pressures, respectively, both forming a first thrust force. The sealing member has a center positioned so that during the orbiting motion of the orbiting scroll, when a second thrust force applied to the orbiting scroll from the working pockets takes a substantially maximum value, a distance between a central point of application of the first thrust force and a central point of application of the second thrust force takes a substantially minimum value.

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： 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： 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： Methods and non-volatile storage systems are provided for recovering data during a programming of non-volatile storage. Program data that was originally stored in one set of latches may be preserved with a combination of two sets of latches. These two sets of latches may also be used to store verify status during programming of that program data. The original program data may be recovered by performing a logical operation on the data in the two sets of latches. For example, upper page data could be initially stored in one set of latches. While the upper page data is being programmed, that set of latches and another set of latches are used to store verify status with respect to the upper page data. If a program error occurs while the upper page data is being preserved, it may be recovered by performing a logical operation on the two sets of latches.
