<p>A scroll-type fluid displacement apparatus includes a pair of scroll members, each having a circular end plate and a spiral wrap element extending from an axial end surface of the circular end plate. An anti-wear plate member is disposed in the inner surface of the end plate of at least one of the scroll members and extends from a first place adjacent the radial center of the end plate to a second place positioned radially and spirally inward of the outer terminal end of the spiral wrap element of the scroll member. An axial gap is formed between the radial center of the inner surface of the end plate of the scroll member and the radial inner end of the spiral wrap element of the opposite scroll member. The radial inner end of the spiral wrap element of one scroll member is thereby prevented from contact with the radial center of the inner surface of the end plate of the other scroll member. <IMAGE></p> |
