摘要： PURPOSE:To reduce noises due to the swing of an Oldham' mechanism by providing the Oldham' mechanism between a bearing section of a turning scroll and a member opposed to the bearing section. CONSTITUTION:An Oldham ring 7 formed on the upper and lower surfaces respectively integrally with a pair of keys 7a, 7b is provided as an Oldham's mechanism for blocking a turning scroll 2 under the turning movement from the rotation a bout its own axis between a bearing section 2d and an end plate 3a opposed thereto. The key 7a of the Oldham ring 7 is inserted in a key way formed on the bearing section 2d and the key 7b is slidably inserted in a key way formed on the end plate 3a. Thus, noises can be remarkably reduced which are generated by the swing of the Oldham ring 7.

摘要： PURPOSE:To increase the compression ratio with a simple arrangement by forming a through-hole in a spiral member in a stationary blade, and by forming a groove in a mirror plate in a movable blade at a position facing the through-hole so that a compression chamber may be communicated with another chamber through the hole and the groove in a short time. CONSTITUTION:A scroll compressor is composed of stationary and movable blades 1, 2. Further, a compression chamber 7 is formed between the stationary blade 1 and the movable blades 2. Further, the stationary blade 1 is formed therein with a center opening 8 through which compressed fluid is discharged. In this arrangement, a spiral member 3 in the stationary blade 1 is formed therein with a through-hole 4 in parallel with the axial direction of the spiral member 3. Meanwhile, the bottom surface 5 of a mirror plate in the movable blade 2 is formed therein with a groove 6 facing the through-hole 4. Further, the hole 4 is communicated with the groove 6, and high pressure gas is introduced selectively and respectively into and outside of the compression chamber 7 when a part of the groove 6 comes to positions inside and outside of the spiral member 3, respectively, so as to inject the fluid. With this arrangement, the compression chamber 7 is communicated with another chamber in a short time so as to increase the compression ratio.

摘要： PURPOSE:To enhance the seal effect between stationary and rotary scroll blades by setting the side surface clearance of a scroll lap on at least one of the scroll blades in such a way that it is made to be larger toward the outer peripheral section of the blade, than those of the center end of the blade and the discharge pressure area. CONSTITUTION:In a scroll compressor, stationary and rotary scroll blades each having a mirror plate on which a spiral scroll lap is planted upright, are meshed with each other. In this arrangement, the side surface clearance of a scroll lap on at least one of these scroll blades is set in such a way that it is made to be larger toward the outer peripheral section of the blade than the center end part of the blade and the discharge pressure area. That is, for example, the semi-arc 101 of the inner periphery of the first half of the second round of the scroll lap has a center O'1 which is shifted in the increasing direction by (e) from the center O1 of a basic shape 201 of the inner periphery of the first half of the second round of the scroll lap, and accordingly, the thickness of the scroll lap in this first half of the second round is decreased by 2e. Consequently, the centers O1, O2 of the semi-arcs 102 through 104 are shifted respectively in the similar manner, thereby it is possible to make the thickness of the scroll lap thinner.

摘要： PURPOSE:To reduce slide loss by introducing sucked gas into an independent space formed by a partition wall on the rear surface side of a stationary blade mirror plate so as to prevent thrust force from concentrating to the center part of the blade. CONSTITUTION:When a compressor is driven, sucked gas is introduced into a compression chamber 7 from a pipe 10 through a port 2c. At this time, a part of the sucked gas is introduced into a lower pressure chamber 9 through a communication hole 12. Meanwhile, gas discharged from a port 2c' is discharged into and outside of a closed container 1 through pipes 11, 15. As a result, the low pressure chamber 9 is held at a suction pressure so that the suction pressure is effected on the rear surface of the mirror plate 2a of a stationary blade 2. Meanwhile, the nearer to the center of a compression chamber 7, the higher the pressure in the chamber 7 becomes, and accordingly, the mirror plate 2a is deformed so as to be warped toward the low pressure chamber 9. Due to such deformation, the thermal expansion of laps 2b which increases toward the center part thereof may be relieved. Accordingly, it is possible to prevent thrust force from concentrating to the center part of the stationary blade 2.

摘要： PURPOSE:To enhance delivery efficiency, by providing a delivery port almost in a symmetrical position in each end plate of a fixed scroll and a turning scroll. CONSTITUTION:A turning scroll 7 and a fixed scroll 8 are constituted vertically providing scroll laps 7b, 8b in mutually opposed surfaces of end plates 7a, 8a. Delivery ports 10, 11, for delivering compressed gas into an enclosed vessel 1, are formed in the vicinity of the center of each end plate 7a, 8a, and both the ports 10, 11 are provided so as to hold an almost symmetrical position relation. Accordingly, a loss by excessive compression can be suppressed to a less amount by holding good balance of gas pressure in both compression chambers.

摘要： PURPOSE:To reduce a thrust force applied to a movable element and prevent a high pressure gas from leaking by providing a thrust force reducing mechanism consisting of an annular body, an annular groove, seal rings, O-rings, etc., which is oppositely positioned on the back of a panel board, on a surface positioned on the movable element side. CONSTITUTION:The main part of a thrust force reducing mechanism 140 consists of an annular body 150 which is oppositely provided on the back of a panel board 123 while in which an annular groove 151 is formed on a surface on the movable element 111 side, a pair of seal rings 152, 153 which are installed in the annular body 150 forming an annular space Q which is closed by these seal rings, the back of the panel board, and the annular groove 151, O-rings 154, 155 formed with an elastic member which gives the rings 152, 153 a pressing force for the movable element 111, and ports 158, 159 which always connect the annular space Q to the high pressure port S and the medium pressure port S' of a compression chamber P. Thereby, a downward thrust to which the panel board 123 is subjected, can be reduced, and possible leakage of high pressure gas due to a swinging motion can be securely prevented, enabling increase in input and the prevention of seizing.

摘要： PURPOSE:To achieve stable lubrication by making a through-hole for leading the lubricant from an oil chamber formed in the rear of an end plate into a compression chamber through the outercircumferential section of the end plate of a movable scroll member. CONSTITUTION:An oil sump 34 for storing the lubricant pumped through rotation of a crank shaft 6 is formed on the backface of an end plate 12 of movable scroll member 7 for scroll compressor contained in an enclosed container 1. While a through-hole 29 for leading the lubricant from the oil chamber 34 into the compression chamber is made through outercircumferential section of the movable scroll member. The opening at the compression chamber side of the through-hole 29 is opened continually through the flange section of fixed scroll member and since the diameter of said through-hole can be set properly, the lubricant necessary for formation of an oil seal film in the compression chamber can be fed properly.

摘要： PURPOSE: To improve the sealing performance of a thrust receiving chamber and improve the faculty of a compressor by forming tapered groove onto a pressure receiving ring for receiving the thrust force of a swing scroll and forming a thrust pressure receiving chamber by arranging two elastic sealing rings into the groove.
CONSTITUTION: The fluid pressure in a working chamber is introduced onto the back surface of a swing scroll 30 through a passage 36, and a pressure receiving ring 29 for supporting the thrust force of the swing scroll is arranged. A groove having the tapered inclined surface 40a and 40b is formed onto the pressure receiving ring 29, and elastic sealing rings 37a and 37b for forming a pressure receiving chamber are arranged in this groove. Therefore, even if the swing scroll moved vertically, the elastic sealing rings follow, and the leak of the fluid in the pressure receiving chamber is prevented, and the thrust force of the swing scroll can be supported stably.
