Abstract
The volumetric fluid compressor device or so-called scroll type compressor device comprises a rotary shaft mounted centrally at the front side of a housing and a movable scroll member having its scroll portion partially contacted with a scroll portion of a fixed scroll member. Sealed chambers or compression chambers delimited between the two scroll portions are contracted towards the center for compressing the refrigerant gas therein. A slider is mounted at the inner end of the rotary shaft for reciprocation radially thereof. An offset pin having an axis offset from the axis of the rotary shaft is fast with the slider and carries the movable scroll member. The slider is normally urged by a compression spring in a direction to reduce the amount of offset, that is, to reduce the radius of offset rotation of the offset pin, and may be urged by the pressure in the compression chamber in a direction to increase the radius of offset rotation of the offset pin against resiliency of the compression spring. With increase in the radius of offset rotation, the contact pressure between the movable and fixed scroll portions is increased with resulting increase of the force of sealing.
