摘要： PROBLEM TO BE SOLVED: To provide a scroll compressor with twin bearing structure journaling a compression part on both sides, in which the bearing structure prevents uneven contact of a bearing part and is easy to be assembled.
SOLUTION: A main shaft of a double-sided scroll compressor is extended to penetrate an oscillating scroll and a pair of fixed scrolls, is rotated together with a slider to oscillate the oscillating scroll, and is provided with first and second support parts rotatably supported in a double support manner on both sides of the oscillating scroll by bearing parts of the fixed scrolls. The support part of the main shaft has bushes fitted to be rotatable with respect to the bearing parts of the fixed scrolls, curved surface parts abutted with an inner peripheral surface of the bushes so as to allow the main shaft to sidlingly move with respect to the bushes, and joint means making the bushes rotate together with the main shaft while allowing the main shaft move sidlingly. The curved surface parts are annular projection parts extended circumferentially around the main shaft approximately throughout a whole circumference of the main shaft and is approximately brought into line-contact with an inner peripheral surface of the bushes, and are in contact with the bushes at approximately central parts in thickness of the fixed scrolls.

摘要： PROBLEM TO BE SOLVED: To provide a scroll compressor in which poor sealeability on a part required for sealing, contact of addendum, abnormal abrasion of an elastic material, and fatigue failure are not generated, and having high performance and high reliability. SOLUTION: A peripheral protrusion 4c outward in the radial-direction is provided over the whole periphery on the outer peripheral surface of a partition plate 4. The outside diameter of the peripheral protrusion 4c is set smaller than the inside diameter of a shell main body 9 by the dimension corresponding to the contraction amount of the shell main body 9 after a shell cover 20 is sealed by welding. That is, a small clearance α is formed between the outer peripheral surface of the peripheral protrusion 4c and the inner peripheral surface of the shell main body 9 before welding. The partition plate 4 is mounted in the shell main body 9, and the partition plate 4 and a frame 3 are fixed to each other. After that, when the shell main body 9 and the shell cover 20 are welded, the outer peripheral surface of the peripheral protrusion 4c of the partition plate 4 and the inner peripheral surface of the shell main body 9 are bonded to each other by contraction of the welded shell 9. Therefore, a space between a high-pressure side space 30 and a low-pressure side space 31 is partitioned and sealed.

CONSTITUTION:A fixed scroll 1 provided with a spiral projection 1b on the bottom of a base plate 1a and an oscillating scroll 2 provided with a spiral projection 2b on the upper surface of a base plate 2a are prepared, and sealing members 8, 9 are inserted into spiral grooves 6, 7 formed on an end surface of each of the spiral projections 1b, 2b. A by-pass port 12 communicating a circular recessed part 1c provided towards the outer periphery of the base plate 1b through to a compression space 5 is provided on the fixed scroll 1. In such a scroll compressor, the sealing member 9 on the side of the oscillating scroll 2 is preliminary cut off A on a part corresponding to the by-pass port 12 of the fixed scroll 1. Then, movement of the sealing member 9 is prevented by a pin 20 set up in the spiral groove 7.

摘要： PURPOSE:To restrain the reduction in the performance of a compressor, and to prevent the seizure of bearing sliding parts by incorporating a fixed scroll, an oscillating scroll, and a motor in a shell, and by forming the lower half part of the shell in a half-rectangular columnar shape. CONSTITUTION:In the inside of a shell 31, a fixed scroll 1, an oscillating scroll 4, and a motor 9, 10 are incorporated, and further lubricating oil is stored therein. The lower half part 31b of the shell 31 is formed in a half-rectangular columnar shape, and an oil reservoir 32 is formed. Since the capacity of the oil reservoir inside the shell 31 is increased, the rising rate of the oil level is lowered, even if the oil inside the oil reservoir 32 is increased during the operation of the compressor. Thus, the reduction in the performance of the compressor can be restrained, and the seizure of the bearing sliding parts can be prevented.

摘要： PURPOSE:To obtain a small-sized bypass mechanism by installing a mechanism for discharging the fluid in a compression chamber outside the compression chamber into the base plate part of a fixed scroll and opening and closing said mechanism by a bypass valve driven by the selection of the suction pressure and discharge pressure. CONSTITUTION:When a compressor is driven with the max. faculty, a bypass hole 14 and a discharge hole 16 are closed by a bypass valve 17, using the pressure in a valve seat space 19 as discharge pressure. In the capacity control, the bypass hole 14 and the discharge hole 16 are allowed to communicate by the opening operation of the bypass valve 17, using the pressure in the valve seat space 19 as suction pressure, and a portion of fluid is discharged outside a fixed scroll 1. Therefore, the bypass mechanism for a compression chamber 5 for the capacity control can be made compact.

摘要： PURPOSE:To stabilize the oil supply by maximizing the fluid resistance of an oil groove of a last thrust bearing in an oil flow path thereby making the pressure loss between the outlet of a pump and the outlet of the thrust bearing higher than the pressure to be boosted by means of a final stage pump means. CONSTITUTION:Lubricant 17 flows through an oil cap 16-an eccentric oil supply hole-a rolling section bearing oil groove 10a-an oil groove 6d-an oil groove 32a. The length and the number of the oil grooves 32a in the thrust bearing 32 are set such that the pressure loss of the lubricant flowing through the oil groove 32a is higher than the pressure to be boosted by a final stage pump means 23. Consequently, when the lubricant flows through the bearing section, negative pressure does not occur thereby intrusion of gas is prevented.
