Abstract:
1. An axial compliant means for a scroll machine, wherein, a second scroll revolving around a first scroll, the pressure of a working fluid as a result of such revolution being on the increase gradually and radial-inwardly among multiple compression chambers including a low pressure chamber, a medium pressure chamber and a high pressure chamber; a force being created by the pressure of a working fluid flowing through the medium pressure chamber; a frame supporting the first and second scrolls; a piston pushed by the force pushing both of the second scroll and the first scroll to be axially in touch with each other; and an axial sealing status being achieved for both of the scrolls is characterized by multiple guiding posts being secured on the sliding travel of the piston; the sliding piston being guided by the multiple guiding posts and the slanting angle of the sliding piston being decreased to achieve better axial sealing results for both of the second scroll and the first scroll, wherein the multiple guiding posts being secured to the first scroll and to the frame by securing bolts; and corresponding multiple guided holes being provided on the circumference of the piston to receive insertion of the multiple guiding posts.
