| Zusammenfassung: | A fluid dispensing system for use in consistently depositing relatively thick and lumpy materials (12) onto receiving surfaces (230) which employs a supply path (14,16,18,20) to a plurality of pump/valve combinations (21-27 + 41-47) and a feedback pressure line (80) to assure an adequate pressure at the point of deposit. There are positive displacement pumps (21-27) which operate continuously through the plurality of valves (41-47) with an additional feedback path (62) to assure constant flow of the material. |
