ABSTRACT:
A scroll-type apparatus having an improved radial seal and a method for the assembly thereof is disclosed. The spiral wrap of a moving scroll and a stationary scroll are provided with gap adjusting means for providing a gap of a desired size between the top surface of the spiral wrap of each scroll and the top surface of the base plate of the opposing scroll. The gap adjustment means comprises a spiral-shaped elastic element which fits into a groove formed in the top surface of a spiral wrap or on top of a protrusion formed on the top surface of the spiral wrap, to form a nonpressurized seal. The elastic element is supported by the spiral wrap by friction, bonding, or solvent welding.
