Fluidic device
In a fluidic drive for disposition between two components which are movable relative to each other comprising a hollow body with a duct for supplying fluid to, and discharging it from, the hollow body wherein the hollow body consists at least partially of a bellows structure, non-resilient ring elements extend around the hollow body in each of its pleats and a connecting structure extends at least at one side of the hollow body and interconnects the non-resilient ring elements.
1. A fluidic drive for disposition between two components which are movable relative to each other, comprising at least one fluid drive element having at least one force transmission area in contact with the components, said fluidic drive element comprising a hollow body with a duct for supplying fluid to, and discharging it from, said hollow body, said hollow body consisting at least partially of a bellows structure with a flexible and non-resilient wall structure consisting of an elastic inner wall and a non-resilient outer wall, non-resilient ring elements extending around said hollow body in each pleat thereof, and a connecting structure extending at least at one side of said hollow body and interconnecting said non-resilient ring elements and being connected to one of the force transmission areas.
2. A fluidic drive according to claim 1 , wherein said non-resilient wall structure consists of a fiber-reinforced material.
3. A fluidic drive according to claim 1 , wherein said hollow body is disposed between said two components which are interconnected by a joint.
4. A fluidic drive for disposition between two components which are movable relative to each other, comprising at least one fluid drive element having at least one force transmission area in contact with the components, said fluidic drive element comprising a hollow body with a duct for supplying fluid to, and discharging it from, said hollow body, said hollow body consisting at least partially of a bellows structure, non-resilient ring elements extending around said hollow body in each pleat thereof, and a connecting structure extending at least at one side of said hollow body and interconnecting said non-resilient ring elements and being connected to one of the force transmission areas, said non-resilient ring elements and said connecting structure consisting of a plastic foil.
5. A fluidic drive according to claim 4 , wherein said non-resilient ring elements and said connecting structure consist of a string.
6. A fluidic drive according to claim 4 , wherein said hollow body is disposed between said two components which are interconnected by a joint.
7. A fluidic drive for disposition between two components which are movable relative to each other, comprising at least one fluid drive element having at least one force transmission area in contact with the components, said fluidic drive element comprising a hollow body with a duct for supplying fluid to, and discharging it from, said hollow body, said hollow body consisting at least partially of a bellows structure, non-resilient ring elements extending around said hollow body in each pleat thereof, and a connecting structure extending at least at one side of said hollow body and interconnecting said non-resilient ring elements and being connected to one of the force transmission areas, said connecting structure is formed by joining adjacent pleats by one of stitching, vulcanizing and cementing.
8. A fluidic drive according to claim 7 , wherein said hollow body is disposed between said two components which are interconnected by a joint.
