Claim Text:
1. A device comprising: a throughput chamber defined by a first wall and a second wall spaced a distance from the first wall; an inlet to guide liquid into the throughput chamber; an outlet to guide liquid out of the throughput chamber into a liquid chamber in fluid communication with downstream conduits leading to a liquid ejector; and a rib having a first length extending along the first wall, the rib protruding from the first wall of the throughput chamber a second length less than the distance between the first wall and the second wall such that the rib and the second wall define a narrowed section in the throughput chamber, the narrowed section extending the first length of the rib, the rib having the second length to enable formation of a meniscus in the narrowed section along the first length of the rib when the inlet is exposed to gas.
