Abstract
A mass displacement drive has at least two corresponding arms and a chamber located at a distal end of each arm, each chamber having a piston moveable therein. A fluid, which may be a gas such as air, enters and exits the chambers at defined intervals to change the buoyancy of the chambers with respect to each other, generating a mass displacement torque to move the arms about the axis.
Claims14
A mass displacement drive comprising;
- a first arm that communicates with an axis and a second arm positioned opposite the axis from the first arm, wherein the second arm communicates with the axis;
- a first chamber located at a distal end of the first arm and a second chamber located at a distal end of the second arm, the first chamber comprising a first piston movable therein and the second chamber comprising a second piston moveable therein
- wherein, in use, movement of the first piston draws fluid into the first chamber to increase buoyancy of the first chamber while movement of the second piston forces fluid from second chamber to decrease buoyancy of the second chamber, with the change in mass of the first chamber relative to the second chamber generating a mass displacement torque to move said arms about said axis.
