Abstract
A guided rotor compressor that contains at least three hollow rollers, each of which has a sheath surrounding a core. The coefficient of friction of the sheath and the core is from about 0.01 to about 0.15, but the coefficient of friction of the core is at least 1.2 times as great as the coefficient of friction of the sheath. The core has a cross-sectional area that is at least about 1.5 times as great as the cross-sectional area of the said sheath. Each of the core and the sheath has a coefficient of thermal expansion of from about 1×10to about 20×10. Each of the core and the sheath has a a notch Izod impact strength of from about 50 Joule-meters to about 100 Joule-meters.
