Abstract
A closure flap on a vacuum inlet valve assembly or housing pivots between an open first position and a closed second position. When the closure flap is in the open first position, it is offset from a central longitudinal axis of the vacuum inlet valve housing. When the closure flap is in the closed second position, it intersects the central longitudinal axis. The closure flap has a resilient and compressible protrusion that releasable locks the closure flap in each position.
