ABSTRACT A scroll type fluid displacement apparatus is disclosed in which a pair of scrolls interfit at an angular and radial offset, each scroll including a circular end plate and a spiral element. The outer wall surface of each spiral element, which extends from an outer terminal end of the spiral element to the point of contact with the outer terminal end of the opposed spiral element at the orbital posi- tion where the sealed off fluid pockets are initially formed, is a rough unfinished surface. Accordingly, the time for manufacturing each spiral element is reduced and waste of material which is pro- duced when the scroll surfaces are finished by turning is decreased.
