摘要： A central vacuum system includes a primary valve box or inlet and a secondary inlet. The central vacuum system includes a hose with a hose plug at the end thereof. The hose is stored in the primary valve box and may be extracted and attached to the secondary inlet. The secondary inlet includes features that enable the hose plug to connect with the secondary inlet. The secondary inlet includes at least one flex member that is configured to connect, in a releasable manner, with a channel formed in the hose plug. The flex member on the secondary inlet includes a section or portion thereof that moves radially relative to a longitudinal axis of the secondary inlet. The portion that moves radially may include a curved profile. This enables the flex member to wrap around a circumferential portion of the hose plug.

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. The hose includes a hose plug connected with a distal end of the hose. The hose plug includes an annular channel and an orthogonally aligned slot. The hose plug may also include a first seal and a second seal.

摘要： 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.

摘要： A vacuum hose storage system includes a housing which is mounted in a storage area of a dwelling and connected to a vacuum source. A length of flexible, expandable hose is mounted in a looped fashion about a plurality of 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. A vacuum source ON/OFF switch is located in the cradle and is actuated when the handle is placed in or removed from the cradle. A control valve on the cradle enables the strength of the vacuum source to be manually controlled by a user.

摘要： A hose cuff on a vacuum hose for connection with at least one inlet valve of a central vacuum system includes a first end, a second end opposite the first end, a longitudinal axis between the first end and the second end, a first section adjacent to the first end, and a second section adjacent to the second end. The first section is adapted to connect to a first inlet valve and the second section is adapted to connect to a different second inlet valve. The first section includes a metal portion adapted to contact pins of the first inlet valve.

摘要： A central vacuum cleaning system includes an inlet valve mounted at various locations in a structure 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.
