Abstract

Official abstract text for this publication.

In a liquid supply apparatus, plungers which respectively expand and contract pump chambers are reciprocated linearly in an axial direction with their phases shifted to each other, thereby continuously discharging liquid. In a pump block, drive rods are mounted so as to be reciprocatable in an axial direction. At a center in an axial direction of shafts attached to the drive rods, drive rollers are mounted, and rollers are mounted at both ends of the shafts. Guide grooves which support the guide rollers are formed in guide blocks.

First claim

Opening claim text (preview).

What is claimed is: 1. A liquid supply apparatus having a plurality of pump chambers and continuously discharging liquid by expanding and contracting the pump chambers at different timings, the apparatus comprising: a pump block in which a plurality of drive rods which expand and contract the respective pump chambers are mounted so as to be reciprocatable in an axial direction; a plurality of shafts corresponding to the respective driving rods, each of the shafts having a center pa…
