ABSTRACT:
A recovery chamber for collection of dirt-laden fluid in a spray-type vacuum cleaning apparatus. The apparatus has a container for collection of the fluid, a vacuum source located at the bottom of the container and an open-ended riser tube centrally mounted in the container and connected in fluid-tight fashion to the vacuum source. The chamber includes an outer housing having a roof portion and an annular side portion. The housing is adapted to cover and be seated on the container. An inner chamber is included which has an annular wall affixed at its top portion to the underside of the roof portion of the outer housing. A fluid entry port is mounted on the side portion of the outer housing facing the annular wall of the inner chamber. The port is for connection to a hose and nozzle for dirt and fluid intake. A float mechanism is mounted on a lower portion of the inner chamber wall and alongside the riser tube. The float mechanism includes a float portion which extends into the container and is adapted to rise upon a rise in liquid level in the container. A vacuum cut-off device is attached to the float mechanism for covering the riser tube when the float mechanism rises an amount corresponding to a predetermined level of liquid in the container to prevent further vacuum action through the riser tube which, in turn, prevents further fluid from entering the container.
