Abstract (en)
Flow rate regulation arrangement for the wash liquor in a clothes washing machine comprising an outer washing tub, a recirculation conduit (1) connected with both the lower and the upper portion of said washing tub, an electromechanical actuator means (2) and an electronic microprocessor means connected to an electric printed-circuit board and arranged to detect and identify the various positions taken by a rotary selector means for letting the various detergents and laundering product into said washing tub at the correct time during the washing process. Said regulation arrangement comprising a cam (5) with a properly contoured outer profile, adapted to be operated by said actuator means (2) and capable of causing, through a cam follower (7) and an alternately displaceable lever (8), said recirculation conduit (1) to be more or less throttled under resulting variation, from a given maximum value to a given minimum one, in the flow rate of the wash liquor pumped through said conduit. <IMAGE>
