Title
(EN) Negating check valve
Abstract
(EN)

A positive displacement pump for dispensing fluid includes a fluid body sub-assembly including a fluid body and a negating check valve. The negating check valve includes a negating body defining a dispensing opening. The fluid body and the negating body form a flow path for the fluid. The fluid is dispensed through the dispensing opening. The positive displacement pump is primed by allowing trapped air within the flow path to flow out of the dispensing opening. The negating check valve may be fully or partially attached to the fluid body. The trapped air within the flow path flows out of the dispensing opening when the negating check valve is partially attached to the fluid body.
