ABSTRACT:
A multi-outlet depositor receives fluid material and displaces first and second portions of the material using first and second mechanisms, respectively, that are coupled together in a manner that causes volume of the first portion to vary according to volume of the second portion. The first portion may equal the second portion. The first and second mechanisms may be coupled using a bolt. The multi-outlet depositor may also include an output for providing the first and second portions. The first and second mechanisms may include positive displacement vane pumps. Each of the vane pumps may include a hub/chamber assembly having a hub and a plurality of vanes disposed within a cylinder. The hub/chamber assembly may have two vanes that interlock and are displaceable along their longitudinal axes.
