Abstract

A pump and purge valve configuration may include an inlet, an outlet arranged downstream of the inlet and defining a portion of an operational fluid pathway, and a pump mechanism arranged along the operational fluid pathway between the inlet and the outlet. The pump and purge valve configuration may also include a purging fluid pathway having a purge inlet in fluid communication with the operational fluid pathway at a point downstream of the pump. The purging fluid pathway may extend from the purge inlet to a relief point. The pump and purge valve configuration may also include a purge valve arranged along the purging fluid pathway. The purge valve may be configured to remain open unless a triggering fluid pressure develops in the pump mechanism.
