Patent number: 8959708Abstract: A handle for a wand of a vacuum cleaning appliance includes a handgrip portion and a conduit for receiving an air flow. The handle includes an aperture for admitting ambient air into the conduit. A first valve occludes a first portion of the aperture, and a second valve occludes a second portion of the aperture. A control mechanism moves the first and second valves away from the aperture to admit ambient air into the conduit. The second valve is supported at least partially by the first valve to occlude the second portion of the aperture.Type: GrantFiled: February 15, 2011Date of Patent: February 24, 2015Assignee: Dyson Technology LimitedInventors: Sean Ventress, David Andrew McLeod

Patent number: 8732902Abstract: A vacuum cleaning head includes a pressure chamber having a first chamber section and a second chamber section which is moveable relative to the first chamber section in response to a pressure differential thereacross from a first position to a second position, and a control mechanism located within the pressure chamber. The control mechanism has a first state for inhibiting the movement of the second chamber section in response to said pressure differential beyond a third position intermediate the first and second positions, and a second state for allowing the second chamber section to move in response to said pressure differential to the second position. The control mechanism is arranged to change between the first and second states in response to a movement of the second chamber section from the third position.Type: GrantFiled: February 22, 2011Date of Patent: May 27, 2014Assignee: Dyson Technology LimitedInventors: David Andrew McLeod, Matthew John Dobson

The handle includes an aperture for admitting ambient air into the conduit. A first valve occludes a first portion of the aperture, and a second valve occludes a second portion of the aperture. A control mechanism moves the first and second valves away from the aperture to admit ambient air into the conduit. To reduce the force required to move the valves away from the aperture, the control mechanism is configured to move the second valve away from the second portion of the aperture before moving the first valve away from the first portion of the aperture.Type: GrantFiled: February 15, 2011Date of Patent: March 18, 2014Assignee: Dyson Technology LimitedInventors: Sean Ventress, David Andrew McLeod

Patent number: 8650709Abstract: A handle for a wand of a vacuum cleaning appliance includes a handgrip portion and a conduit for receiving an air flow. The handle includes an aperture for admitting ambient air into the conduit. A first valve occludes a first portion of the aperture, and a second valve occludes a second portion of the aperture. A control mechanism moves the first and second valves away from the aperture to admit ambient air into the conduit. To vary the air flow into the conduit, the control mechanism includes a first manually operable actuator located on the handle for moving both of the first and second valves away from the aperture, and a second manually operable actuator is located on the handle for moving only one of the first and second valves away from its respective portion of the aperture.Type: GrantFiled: February 22, 2011Date of Patent: February 18, 2014Assignee: Dyson Technology LimitedInventors: David Andrew McLeod, Matthew John Dobson, Sean Ventress
