Abstract

956,764. Suction cleaners. LICENTIA PATENT-VERWALTUNGS G.m.b.H. April 18, 1963 [April 24, 1962], No. 15351/63. Heading A4F. In a suction cleaner of the kind having a built-in fan operated by an electromotor and a dust bag arranged in the interior of the apparatus casing, a manually adjustable valve for regulating the suction also acts as an automatic safety valve for the delivery of by-pass cooling air to the fan motor. The valve operating knob 4 is turned manually to rotate the valve plate 6 in contact with the curved wall 1 of the apparatus casing to open the valve to the desired extent to allow air into the apparatus casing to reduce the suction. Should the flow of cooling air for the fan motor be reduced when the valve is closed, e.g. due to an obstruction in the air duct or to the filling of the dust bag, the resulting increased suction at the fan inlet side will draw the plate 6 downwardly against the action of a spring 7 to open the valve.
