Abstract
Scroll-type pumping apparatus comprises a stator (104) comprising a fixed scroll member (106) having an end plate with a first spiral wrap (110) extending therefrom; an orbital scroll member (108) having an end plate with a second spiral wrap (112) extending therefrom to intermesh with the first spiral wrap; a plurality of flexible supports (118) each having one end connected to the orbital scroll member and another end connected to the stator to support the orbital scroll member relative to the stator, and a linear drive system (120) for driving the orbital scroll member to orbit relative to the fixed scroll member. The use of a linear drive system in combination with the flexible supports can provide apparatus having no rotational or rubbing parts.
