Fluid delivery system, and associated appratus and method

摘要

A fluid delivery system for an in ovo injection apparatus is provided. Such a fluid delivery system includes a plurality of fluid pumps each having a select valve, a diaphragm valve, and an outlet valve. The select valves are individually controllable such that each select valve is selectively operated via a pneumatic actuator. The diaphragm valves and the outlet valves are commonly operated via respective pneumatic actuators. An input valve is provided for each fluid pump in instances that require high pressure delivery of a fluid substance via the fluid pumps. In such instances, the input valves and the diaphragm valves are commonly controlled via high pressure solenoid valves, while the select valves are selectively controlled and the outlet valves are commonly controlled via low pressure solenoid valves. An associated apparatus and method are also provided.
