Patent ID: 8479353

Claim:
A hose valve for central vacuum cleaning systems having retractable suction hoses that retract into a system vacuum pipe, the hose valve comprising: a valve box formed to define an interior volume, and a connection port arranged and disposed for communication with the interior volume; a locking assembly secured to the valve box, the locking assembly defining a passage for receiving and guiding a retractable hose that extends through the interior volume, and through the locking assembly, the locking assembly comprising: a compression cylinder having a radially inner cylinder surface disposed about a longitudinal axis, and a sleeve seat formed around the radially inner cylinder surface, the compression cylinder also having a radially outer cylinder surface; a cylindrical deformable sleeve coaxially disposed within the compression cylinder, the deformable sleeve having a compression end arranged to engage the sleeve seat, and a flange end formed to be secured to the connection port of the valve box, the deformable sleeve being radially inwardly deformable responsive to an axial compressive force directed parallel to the longitudinal axis of the compression cylinder; and thrust means engageable with the compression cylinder to impose a compressive 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 compressing position where the deformable sleeve is axially compressed to cause deformation with its walls collapsing radially inward to form a seal around a retractable hose disposed through the locking assembly.
