  • Device for the synchronous conveying of flowable materials in a mixing device
    Patent number: 6315442
    Abstract: Instead of a discontinuous mixing process for mixing two or more flowable materials for a paint-spraying plant, a continuous mixing and conveying process is provided. Use is made of individual conveyor pumps driven individually by hydraulic adjusting units in the form of double-acting hydraulic cylinders. Control is exerted by an electronic control device controlling a proportional governor at hydraulic connecting lines between the adjusting units to adjust the stroke of pistons of the adjusting units and thus the ratio of the flowable material conveyed.
    Type: Grant
