Abstract (en)
In a scroll-type fluid displacement apparatus, an orbiting scroll has a first and a second grooves formed on a second surface of a second circular end plate, so that the grooves are diametrically opposed to each other. An Oldham coupling is disposed between the orbiting scroll and the housing for preventing the rotation of the orbiting scroll during orbital motion thereby The Oldham coupling has a pair of engaging portions formed thereon for slidably engaging the first and second grooves of the orbiting scroll. A reinforcing device is thus located on the second surface of the second circular end plate of the orbiting scroll and extends across the first groove for reinforcing the circular end plate of the orbiting scroll. Thereby, a scroll-type fluid displacement apparatus may prevent deformation, scuffing and seizures of scroll member while simultaneously maintaining the thickness of the scroll members. <IMAGE>
