Claims

[Scope of utility model registration request]

In a scroll fluid system in which a fixed scroll 7 and a revolving scroll 8 are disposed side by side in mesh with each other, and a rotary shaft 10 is connected to the back surface of an end plate 12 of the revolving scroll 8 eccentrically from the center of the revolving scroll, the rotary shaft 10 is A fitted fixed frame 21 is arranged adjacent to the back side of the revolving scroll end plate 12, and between the end plate 12 and the fixed frame 21, a scroll key 32b and a frame key 32c are inserted into a ring 32a into which the rotating shaft 10 is fitted. An Oldham joint 32 with a protruding cross shape is interposed,
a keyway 34 into which each of the keys 32b, 32c fits;
A counter member 3 is provided with a pair of keys 33b protruding from the ring 33a corresponding to the ring 32a and the frame key 32c.
3 is provided in contact with the Oldham joint 32, and an eccentric plate 37 eccentric in the direction opposite to the eccentric direction of the revolving scroll 8 is provided on the rotating shaft 10 in contact with the inner peripheral surface of the ring 33a of the counter member 33, Due to the rotation of the rotating shaft 10, the Oldham joint 32 is moved toward the frame key 32c toward the counter member 33.
A scroll fluid device characterized in that the two reciprocate in opposite directions relative to the Oldham joint 32.
