Patent ID: 7726331

Claim:
A modular fluid handling device comprising: a. a block having a series of block sides extending between a block top face and an opposing block bottom face, wherein the blocks may be arrayed together in side-to-side abutting relationship with other identical blocks to form a two-dimensional array of blocks, the block including: (1) a central block bore extending between the block faces, whereby the block may be arrayed with other identical blocks in face-to-face abutting relationship to form a stacked array of blocks wherein abutting blocks have their block bores coaxially aligned; (2) one or more ducts extending between the block bore and one or more of the block faces and sides; b. an elongated shaft centrally mounted within the block bore; c. at least one of: (1) a rotor disc having: (a) opposing disc faces; (b) an outer disc circumference radially bounding the disc faces, the disc circumference being complementarily fit within the block bore; (c) a disc bore centrally defined in, and extending between, the disc faces, the disc bore having the shaft received therein; (d) one or more disc fluid passages: (i) extending between the disc faces, and (ii) situated between the disc bore and the disc circumference; (2) a star wheel having: (a) a central hub having multiple vanes extending therefrom, (b) opposing wheel faces axially bounding the hub and vanes; (c) an outer wheel circumference radially bounding the vanes, the wheel circumference being complementarily fit within the block bore; (d) a wheel bore centrally defined in, and extending between, the wheel faces, the wheel bore having the shaft received therein.
