Abstract:
A device for the continuous, synchronous conveying of flowable materials into a mixing device comprising:a drive motor including a drive piston for driving drive fluid;a first hydraulic adjusting unit including a first operating piston in a first operating cylinder, said first piston capable of being driven by said drive piston;a second hydraulic adjusting unit including a second operating piston in a second operating cylinder, said second operating cylinder being hydraulically connected to said first operating cylinder;a first distance position sensor sensing a stroke length of said first operating piston and providing a first measuring signal;a second position sensor sensing a stroke length for said second operating piston and providing a second measuring signal; anda control device responsive to the first and second measuring signals to provide a synchronous conveying of a constant mixture ratio-of the flowable materials,wherein the hydraulic connection between said first operating cylinder and said second operating cylinder provides hydraulic pressure to drive said second operating piston.
