ABSTRACT:
A longitudinally extending housing (21) is provided with a generally cylindrical side wall (22) closed by opposed end walls (23,24). The housing side wall is ported, to connect with supply and return lines (17,18) from a source of pressurized fluid (15), and also to connect with the input and discharge lines (19,20) of a process loop. The housing contains a longitudinally extending rotary axle (33) which forms a part of a valve rotator assembly (42). The assembly includes a plurality of segmental discs (43-46) mounted for rotation with the axle. Axially aligned alternate disc edges are joined by radial longitudinally extending partitions (52,53) to form a plurality of alternating axially oppositely facing rotary chambers (I-IV) adapted to communicate with the housing ports. Two diametrically opposed chambers (II,IV) are of generally equal arcuate extent and size, while the other diametrically opposed chambers (I,III) are of differing arcuate extent and size with one chamber (III) being of substantially lesser arcuate extent than the other (I). Fluid flowing through the housing between ports is always directed across the disc faces parallel to the spaced planes, and flows through the housing generally diametrically. The entire perimeter of the valve rotator assembly is sealed to the circumferential housing side wall by seals (60,61) extending along the arcuate disc edges. In a second embodiment, longitudinal seals (62) are additionally disposed along the outer longitudinal edges of the partitions.
