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.

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 by a locking finger engaging an adjacent section of the hose. An electric switch on the inlet valve enables a user to actuate the vacuum supply source. 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.

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 central vacuum cleaning system includes a locking collar 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 therefrom for cleaning an adjacent area. A pair of O-rings within the collar frictionally retains a 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 the collar automatically locks the hose in a selected extended position when manually pulled from the collar by a locking finger engaging an adjacent section of the hose. An electric switch on the collar enables a user to actuate the vacuum supply source. A mounting bracket enables the collar to be mounted at various locations in the structure and a ring formed on the collar enables the collar to be rotated to a desired position on the mounting bracket.
摘要翻译： 中央真空清洁系统包括安装在结构或RV中的各个位置并连接到真空管道的入口端的锁定环。 软管的一部分可滑动地安装在管道内并从其中延伸以清洁相邻区域。 当软管处于缩回位置并且在手柄和真空供应管道之间提供空气密封时，套环内的一对O形环摩擦地保持安装在软管的端部上的手柄处于存储位置。 安装在轴环上的锁定机构通过与软管的相邻部分接合的锁定手动手动地从套环拉动时，自动将软管锁定在选定的延伸位置。 轴环上的电开关使用户能够致动真空源。 安装支架使得套环能够安装在结构中的各个位置处，并且形成在套环上的环使得套环能够旋转到安装支架上的期望位置。

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.
