Kind Code:
A
Abstract:
Scroll-type pumping apparatus comprises a stator ( 104 ) comprising a fixed scroll member ( 106 ) having an end plate with a first spiral wrap ( 118 ) extending therefrom, and an orbital scroll member ( 108 ) having an end plate with a second spiral wrap ( 120 ) extending therefrom to intermesh with the first spiral wrap ( 118 ). A motor drives a drive shaft for generating orbital movement of the orbital scroll member relative to the fixed scroll member ( 106 ). The apparatus comprises a plurality of flexible rods ( 122 ) arranged about the drive shaft and each having one end connected to the orbital scroll member ( 108 ) and another end connected to the stator ( 104 ) to support the orbital scroll member ( 108 ) relative to the stator and to inhibit rotation of the orbital scroll member.
