Method of assembling volumetric infusion pump by locating elements relative to datum surface, typically shaft bore

ypically three shafts form part of the pump. By referencing all points in the pump relative to these shafts (and thereby to chassis 14) it is stated that the pump structure can be indexed without the necessity of a wide variety of precision machined parts, whilst maintaining the requisite accuracy o...

Summary:ypically three shafts form part of the pump. By referencing all points in the pump relative to these shafts (and thereby to chassis 14) it is stated that the pump structure can be indexed without the necessity of a wide variety of precision machined parts, whilst maintaining the requisite accuracy of the completed assembly.
