  • Control device for controlling machines by hand or foot
    Patent number: 7032471
    Abstract: The invention relates to a control device for controlling machines, especially hydraulic machines, by hand or foot. The inventive device comprises an actuating element (1), especially a pedal or a control lever, which can be moved in several directions. The aim of the invention is to feel a resisting force when the actuating element (1) is displaced or adjusted, whereby said force is on the scale of hydraulic forces having a direct effect. The actuating element (1) engages with a transmitter device (3) which is not hydraulic or is hydraulically decoupled from the hydraulic system. A damping device (6) engages with the actuating element (1). Said damping device defies the movement in at least one direction of motion pertaining to the actuating element (1) by means of a fluid that is moved by the actuating element (1).
