Filed: 1988-01-18
Abstract: PURPOSE:To easily improve the abrasion resistance of the ends of blade portions and improve compression efficiency by integrally injecting a scroll shaped blade portion to a blade bottom portion made of a synthetic resin while insert molding abrasion resistant bodies on the ends of the blade portions. CONSTITUTION:A scroll blade consists of a fixed scroll 8 and a revolving scroll 11 which slides while being fitted to the scroll blades of the fixed scroll. In this case, a synthetic resin with high rigidity is used for the scroll blade and scroll shaped blade portions 1b are injection molded in an integrated form with the blade bottom portion (a) thereof. At the time of the injection molding, abrasion resistant bodies (c) are insert molded on the ends of the blade portions 1b.
