摘要： PROBLEM TO BE SOLVED: To control thrust loading applied to a roller, and obtain sufficient high and low pressure sealing performance. SOLUTION: This helical blade type compressor is so constituted that the compressor is equipped with a case 1, a cylinder 12 in a cylindrical shape provided in the inside of the case, and with a spiral blade 17 with an unequal pitch which partitions a compression chamber 18 in such a way that its capacity is gradually made smaller in the axial direction, in a space between the cylinder 12 and the roller 14, and the revolving operations of the cylinder 12 and the roller 14 thereby allows the compression chamber 18 to be moved to the direction that its capacity is gradually made smaller, so as to allow gas to be compressed, and the compressor is provided with at least one sealing ring 19 separating the inner pressure of the case 1 from the inner pressure of the compression chamber 18.

摘要： PURPOSE: To carry out highly efficient refrigerant compression even in the case of using an alternative refrigerant by making a value found by an expression derived from an equivalent diameter of a discharge port, discharge port length and compressor excluded volume as a specific value. CONSTITUTION: A refrigerant is compressed in a compression chamber 47 partitioned by a blade 45 constantly making contact with an outer peripheral surface of each of rollers 31, 33 in accordance with eccentric rotation of the rollers 31, 33 by two cylinders 13, 15 at the time of driving a rotary compressor. At this time, the refrigerant is sucked in the compression chamber 47 through a suction port 41 from a suction pipe 39, and discharged gas after compression is discharged from a discharge port 37. In this case, when it is specified that an equivalent diameter of the discharge port 37 (discharge port cross-sectional area mm /discharge port cross-section circumferential length mm) is Dm(mm), discharge port length L(mm) and compressor excluded volume Vst (cc), a shape in which a value derived under an expression Dm .√L/Vst becomes 4-8 is formed.

摘要： PURPOSE:To reduce pressure losses and thus enhance compression ratio by disposing rectilinear portions that form one of compression chambers into a high compression chamber, inside a center end portion where the spiral bodies of fixed and turning scrolls are opposite each other, and in the area of a discharge port. CONSTITUTION:A fixed scroll 25 has a spiral body 29 that rises from an end plate. A turning scroll 27 has a spiral body 31 that meshes with the spiral body 29 of the fixed scroll 25, forms two compression chambers of gradually decreasing capacity toward a center discharge port 39, and rises from the end plate. A shaft is rotationally driven by a drive means and has an eccentric shaft portion 19 that passes through the bearing portion 33 of the turning scroll 27. Rectilinear portions 29a, 31a that form one of the compression chambers into a high compression chamber are disposed inside a center end portion where both spiral bodies 29, 31 are opposite each other, and in the area of the delivery port 39. Therefore, compression ratio can be enhanced as pressure losses are reduced.

摘要： PURPOSE:To surely feed oil without being affected by various operating conditions by providing a pump room with an oil inlet which communicates with both an oil introducing passage whose one end faces the inside of the surface of lubricating oil and an oil outlet which communicates with an oil feed passage. CONSTITUTION:In a space defined by a rotor 21, a cylinder 17 and a bearing member 19, a pump room 49 is formed by an eccentric ring 53 which is put in turning motion in conjunction with the rotor 21 and by a vane 55 which moves back and forth correspondingly to the turning motion of the eccentric ring 53. The pump room 49 is provided with an oil inlet 59 which communicates with an oil introducing passage 57 whose one end faces under the level of lubricating oil. Also, an oil outlet 63 is provided which communicates with an oil feed passage 61 through which the lubricating oil is fed to the cylinder bearing surface 18 of the bearing member 19 and the bearing surface 24 of the rotor. Therefore, the lubricating oil can surely be fed to each of the bearing surfaces 18 of the bearing member 19 without being affected by operating conditions such as delivery pressure. Thus inconvenience such as seizure does not occur and stable operating state is secured.

摘要： PURPOSE:To reduce overturning moment that is about to act upon the turning element side by providing a line, connecting the center in the height direction of a turning scroll vane to the axial center of a crank bearing part, orthogonally to the axis of a crankshaft part. CONSTITUTION:A line (c), connecting the center (a) in the height direction of a turning scroll vane 18 to the axial center (b) of a crank bearing part 19a, is provided orthogonally to the axis of a crankshaft part 8. The axial position between the action point of gas pressure load acting upon the turning scroll vane 18 during compression action and the action point Fr of reaction acting upon the crank bearing part 19a can be thereby conformed. This prevents overturning moment from acting upon the turning element side, and thereby suppresses the efficiency lowering generated by the existence of overturning moment.

摘要： PURPOSE:To prevent load from being concentrated onto a part of a blade by carrying fluid which comes in a working chamber from the inlet end side of a cylinder when a rotor is relatively turned against a cylinder, to a working chamber at a discharge end side so as to be discharged outside, and thereby making the capacity of the first chamber at the inlet end side maximum. CONSTITUTION:The cylinder 7 of a fluid compressor is made gradually small in inner diameter toward the discharge end side from the inlet end side. In addition, a rotor 21 is formed into a conical shape which is made gradually small in inner diameter toward the discharge end side from the inlet end side in such a way that the first working chamber 35 at the inlet end side is made to secure the maximum capacity even if a large twisting angle is not given to a blade 33. Excessive load is not thereby concentrated to a part of the blade 33 which is formed in the outer circumferential surface of a rotor 21 at an equal pitch, and also is fitted in a groove 31 in a spiral shape in such a way as to be freely accessed to, stable operations can thereby be secured for a long time.

摘要： PURPOSE:To enable efficient suction with an engaging part of an Oldham's coupling prevented from obstructing a gas flow by extending a side wall surface, corresponding to the engaging part of the Oldham's coupling of a fixed frame in a closed vessel, to the outer side to form gas passage space. CONSTITUTION:In a scroll compressor, the first and second disk-shaped movable scroll members 23, 24, having volute scroll blades 25, 26, are meshed placing the scroll blades 25, 26 of these scroll members in the inside with each other. By an Oldham's coupling, turning force is transmitted from the first movable scroll member 23, driven by a motor driving part, to the second movable scroll member 24 in a condition that the scroll members can be rotated around a shaft of the compressor. Here a side wall surface, corresponding to each engaging part 28 of the Oldham's coupling of the first fixed frame 22 and the second fixed frame (not shown), is extended to the outside to form gas passage spaces 31, 32. In this way, suction of refrigerant gas through a suction pipe 30 is effectively performed.
