摘要： A scroll compressor includes a compressor housing made up of a cup-like first casing having a suction port defined therein and a cap-like second casing having a discharge port defined therein. The compressor housing accommodates a stationary scroll member having a stationary end plate and a stationary scroll wrap protruding axially from the stationary end plate, and an orbiting scroll member having an orbiting end plate and an orbiting scroll wrap protruding axially from the orbiting end plate, with the orbiting scroll wrap being in engagement with the stationary scroll wrap to define a plurality of working pockets therebetween. At least one shim is interposed between mating surfaces of the first and second casings to regulate axial gaps between axial end surfaces of the stationary and orbiting scroll wraps and the orbiting and stationary end plates opposed thereto. The stationary end plate is positioned in the proximity of the mating surfaces of the first and second casings so that a low-pressure chamber is defined between the stationary end plate and the first casing, while a high-pressure chamber is defined between the stationary end plate and the second casing. The location of the stationary end plate in the proximity of the mating surfaces of the first and second casings reduces a variation in the axial gaps referred to above.

摘要： A scroll compressor includes a stationary scroll and an orbiting scroll having respective wrap elements in engagement with each other. An inner end portion of an internal wall of one of the wrap elements is partially shaped to represent a curve identical to or approximate to an envelope curve which is obtained through circular translation of a circular arc connected with an external wall of the other wrap element. The radius of the circular arc is so chosen as to increase the shortest distance a.sub.x from each of points on the curve to the external wall of the one wrap element towards the inner end of the one wrap element.

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： The present invention provides a low-pressure scroll compressor for use in a refrigerating system of an air conditioning apparatus or the like. Lubricating oil is intermittently supplied to a compressor unit in proportional relation to the rotating number of the motor, avoiding an excessive or insufficient supply of a lubricating oil and realizing a proper supply of the lubricating oil even in high-speed rotation of the motor. Thus the compressor is highly reliable. Further, a screening plate is provided in the suction space of a compressor, so that the lubricating oil in the coolant or cooling medium can be effectively separated from the coolant, resulting in enhancement of collecting efficiency of the lubricating oil. Moreover, the screening plate is useful to prevent a hermetic terminal from being cooled by the returning coolant. Otherwise, dew condensation would occur on the hermetic terminal, and leakage or shortcircuiting would be caused, a vital obstacle to the safety of the compressor.

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.
