Abstract

PURPOSE: To suppress vibration and improve the compression efficiency by forming the whole of the surface part from the iron-base alloy and forming the inside from the metal which is more lightweight, in the roller of a rotary compression element which is driven by a motor-driven element.
CONSTITUTION: As for a sealed type rotary compressor, a motor-driven element 2 and a rotary compression element 3 are housed inside a sealed container 1. As for the rotary compression element 3, a roller 10 is housed inside a cylinder 7, and is engaged with the eccentric part 11 of a rotary shaft 5 of the motor-driven element 2. In this constitution, the whole of the surface part of the roller 10 is made of the iron-base alloy 16 having the abrasion resistance, and the inside is formed from the material 17 which is more lightweight than the iron base alloy 16. Therefore, the roller 10 can be made lightweight, and the vibration accompanied with the excentric revolution can be suppressed. Further, the abrasion between the roller 10 and a slidable vane 12 can be prevented.
