Patent CA-2087558-A1 (CA)
Inventor: STEINER ROBERT E
IPC: A47L5/14
Filed: 1993-01-19
Abstract: A variable high/low vacuum/blower device is disclosed as including an interchangeable vacuum or blower device with high pressure/low air flow or low pressure/high air flow operation.          The device includes a housing having air flow channels.  Air inlet and air outlet ports or openings extend through the housing and are connected to the air flow channels.  Motor driven blower wheels create air flow through the air flow channels.  A first valve, operable between first and second position, can selectively change the air flow in the air flow channels from high pressure/low air flow to low pressure/high air flow, while a second valve, also operable between first and second positions, can selectively change the air flow through the air inlet and air outlet ports or openings, enabling the device to operate either as a vacuum or blower device.  The first valve, when operable in a first position, directs exhausted air from the lower blower wheel to the upper blower wheel for high pressure/low air flow operation.  In its second position, the first valve enables intake air to be directed to the upper blower wheel, in addition to the normal intake of air by the lower blower wheel.  The second valve is located at an exit area of the air flow channels for selectively changing the air flow, in order to enable the device to operate as either a vacuum or blower.
