摘要： A vacuum hose storage system includes a housing which is mounted in a storage area of a dwelling or vehicle and connected to a vacuum source. A length of flexible, expandable cleaning hose is mounted in a looped fashion about a plurality of spaced rollers rotatably mounted within the housing. A handle is attached to one end of the hose and is seated in a cradle formed in the housing when the hose is in a fully retracted position within the housing. The cradle is mounted in the housing and receives the open end of the hose when not in use and enables other vacuum tubes in the structure to be operational without shutting off the vacuum to the stored hose. An ON/OFF switch is located in the cradle for controlling the vacuum source and is actuated when the handle is placed in or removed from the cradle. The hose has an internal helical spring which biases the hose toward a retracted position about the spaced rollers within the housing.

摘要： A central vacuum cleaning system includes an inlet valve mounted at various locations in a structure or RV and connected to the inlet end of a vacuum conduit. A section of hose is slidably mounted within the conduit and extends from the inlet valve for cleaning an adjacent area. A pair of seals within the inlet valve retains a nozzle handle mounted on the end of the hose in a stored position when the hose is in a retracted position and provides an air seal between the handle and vacuum supply conduit. A locking mechanism mounted on one embodiment of the inlet valves automatically locks the hose in a selected extended position when manually pulled from the inlet valve. A mounting bracket enables the inlet valve to be mounted at various locations in the structure and a pair of seals enables the inlet valve to be open to the ambient atmosphere.
