Abstract

PURPOSE: To increase sealing performance for sealed space and also to improve lubricating performance and mechanical performance by an arrangement wherein a soft material is installed on grooves of both scrolls and the head of a lap, and a wear resisting material is installed on the sliding face of each end plate of both scrolls.
CONSTITUTION: From depressing a fixed scroll 1 and a turning scroll 2 axially, soft materials 10a, 10b installed on the heads of laps 1b, 2b of both scrolls 1, 2 are easily deformed plastically, therefore an ideal sealed space 9 can be formed. Then, a wear resisting material 12 retained thereby through an elastic element 13 installed on the sliding face 11 of an end plate 1a of the fixed scroll 1 comes in contact ideally with the sliding face 11 of an end plate 2a of the turning scroll 2, and an ideal space sealing is retained without exerting an excessive depressing force on both laps 1b, 2b, thus improving lubricating performance and mechanical performance and also preventing a seizure from occurring at the beginning of start-up.
