(7a>) and a protrusion (7b) that is guided by a guide groove (6d) formed in the housing (6) at the lower part, and the center line of the guide groove (7a) and the center line of the protrusion (7b) are 6 (8) is a closed container that accommodates and supports the pressure element and the electric element consisting of the above-mentioned parts, and (9) is a closed container that is formed in a vertically extending manner. Suction pipe that supplies low pressure gas, 1+α is fixed scroll fi
This is a discharge pipe that discharges high-pressure gas discharged from the + discharge port (Ic) to the outside of the closed container αe.It is configured as described above, and the oscillating scroll (2) is moved by the rotation of the electric motor to the crankshaft (3). The oscillating scroll (2) is driven eccentrically by the protrusion (2d) of the oscillating scroll (2) inserted into the guide groove (7a) of the Oldham joint (7) which is movable in the front and back direction within the housing (6). ), each part of the oscillating scroll (2) rotates at a predetermined radius and performs a so-called oscillating movement.As a result, the fixed scroll (11 teeth (xa) The nitrogen space, that is, the compression chamber created between the teeth (2a) of the sufu 0-/I/(21) moves to the center while reducing its volume, and discharges compressed gas from the discharge port (Ic). Figure 8 shows a state in which the volume of the compression chamber decreases as the swinging motion of the swinging scroll (2) progresses, with the center point of the fixed scroll (1) set at 0 and the center side end of the swinging scroll (2). P and Tn are the center points of the oscillating scroll (2). The center point Q moves in parallel with the same radius as point P, and the length of the radius OP is determined by the eccentricity 5I (2c

一体に形成される固定ａｎ；板。As described above, the side surfaces of the teeth (ta) (2a) of the fixed scroll (1) and the swinging scroll (2) slide while maintaining contact, forming compression chambers (xia) to (lld), and As the oscillating motion continues, the pressure of the gas contained in the circular portion increases and moves to the center. However, if the shapes and dimensions of the constant scroll Ill and the oscillating scroll (2) are incorrect, compression <= (ira ) to (lid), and the ability as a pressure +1iiFA has deteriorated due to compressed scum from the 9th plate (2b) with good surface roughness on the contact surface.
), simple stability and wear resistance are required. As a result, there was a disadvantage that the time required for machining the fabric was increased, and expensive materials with excellent abrasion resistance were required, resulting in an increase in the price of the material. The purpose is to improve the shortcomings of the conventional one. Hereinafter, a sister example of this invention will be described with reference to FIG. 9. In the figure, the same reference numerals as in FIGS. 1 to 8 indicate the same or corresponding parts, and ■ indicates a fixed plate formed integrally with the teeth (1a) of the fixed scroll +11.
