Abstract (en)
[origin: EP0271456A2] A device for adjusting the delivery of a pump for metering liquid products, particularly in agriculture, to be applied in precisely delivered dosed amounts, comprises an excentric bearing driving shaft (3), on which a cam (16) is mounted in an excentrically offset manner, the excentricity of which can be controlled by means of a gear driven by an operator through a control wheel (7), so that the parts with an excentric motion are reduced in number and a precise metering is ensured in view of a full turn of the wheel (7) varying the pump delivery from a minimum to a maximum.
