Abstract
A suction cleaner includes a nozzle body having a suction inlet and a handle pivotally connected to the nozzle body. A suction creating device is located in one of the handle and the body. An air passageway leads from the suction inlet to the suction creating device. A valve member is located in the air passageway. The valve member includes a shaft pivotally mounted in the nozzle body and a valve element fixedly mounted on the shaft. The valve member is selectively pivoted in a first direction by a lever pivotally mounted on the nozzle body and actuated by a movement of the handle of the suction cleaner. A link member, having a first end secured to the lever and a second end secured to the shaft, connects the lever to the valve member. A biasing member, preferably mounted on the shaft, urges the valve member in a second direction.
