Abstract

A delayed shutoff device comprises a conduit configured to allow a fluid to flow through, wherein the conduit includes a conduit start and a conduit end. The device further comprises a plug configured to be placed inside the conduit at the conduit start; move inside the conduit from the conduit start toward the conduit end when the fluid flows through the conduit; and reduce the fluid flow upon reaching the conduit end. The device is configured to allow a pass-through quantity of the fluid to pass through the conduit while the plug moves from the conduit start to the conduit end. The conduit end may form a seat, the plug being configured to stop moving upon reaching the seat. The plug may be configured to fit the seat imperfectly, to allow a seepage of the fluid after reaching the seat.
