Hose Valve Apparatus and Method for Retractable Hose Vaccum Systems |
摘要 |
A hose valve for central vacuum cleaning systems that employ retractable suction hoses of the type that retract into a system vacuum pipe. The hose valve comprises a valve box with a connection port wherein a locking assembly is secured within the valve box. The locking assembly includes a compression cylinder. A cylindrical deformable sleeve is coaxially disposed within the compression cylinder. The deformable sleeve is radially inwardly deformable responsive to an axial compressive force. A thrust means is provided for engagement with the compression cylinder to impose a compressing force on the deformable sleeve. The thrust means being axially movable from a first unlocked non-compressing position where the deformable sleeve is in its non-deformed condition, to a second locked compressed position where the deformable sleeve is compressed to cause deformation with its walls collapsing radially inward to form a seal around a retractable hose disposed through the locking assembly.
