摘要： A retractable hose central vacuum cleaning system comprising a retractable vacuum hose configured to retract through a valve assembly, into a system vacuum pipe responsive to the vacuum communicated from a vacuum source. The valve assembly comprising a static valve seal adapted for coupling a system vacuum pipe to the vacuum hose to create a substantially air-tight sealed communication between the system vacuum pipe and the vacuum hose. The static valve seal being adjustable from a first unsealed configuration where the vacuum hose can move freely through the valve assembly and system vacuum pipe, to a second sealed configuration where the vacuum hose is in sealed communication with a system vacuum pipe, and where the vacuum hose is substantially fixed in relative position to the valve assembly. Wherein movement from first configuration to the second configuration locks the vacuum hose in place relative to the valve assembly.

摘要： A retractable hose vacuum cleaning system comprising a retractable vacuum hose configured to retract through a dual port valve assembly, into a system vacuum tube responsive to the vacuum communicated from a vacuum source. The dual port valve assembly comprising one port adapted to receive the full length of a retractable vacuum hose into a system vacuum tube for storage, a second port adapted to connect to the hose end fitting and supply electrical grounding, electrical power and vacuum to the hose for use, valve seals to stop air flow through the port that is not in use and a third port to connect the valve to the system vacuum source. The dual port valve assembly also comprises a debris trap.

摘要： An adaptable vacuum cleaning unit featuring adjustable debris can egress direction, a filter canister assembly having multiple canister doors and vacuum inlet ports, a canister mounted vacuum producer, and a debris can lifting and locking bar. The vacuum cleaning unit separator assembly includes a separator filter canister assembly mounted to a rotatable base assembly having a debris can, whereby rotation of attachment of the base assembly to the filter canister assembly allows the orientation of the debris can to be rotated relative to the position of the separator filter canister assembly. The casing of the separator filter canister assembly has multiple access doors and vacuum inlets. The vacuum cleaning unit further features lifting lugs around the top edge of the filter canister assembly and forklift slots in the base of the unit. The adaptable vacuum unit also includes an adjustable speed vacuum producer that permits control of the rate of air flow.

摘要： A hose retractor valve for central vacuum cleaning systems that utilize retractable suction hoses that retract into a system vacuum tubing for storage. The hose retractor valve includes a vacuum assisted hose lock and seal assembly comprising a tapered cylinder and an elastomeric cylinder which restrain the vacuum hose from being drawn into the system vacuum tubing while in use, and seals around the hose outer diameter to prevent air from passing between the inside of the system vacuum tubing and exterior of the hose at the valve assembly. The hose lock and seal assembly is self-locking and vacuum assisted, while also permitting additional hose to be extracted by pulling on the hose.
