Abstract

The invention relates to a retractable device. The device includes a body having a wall including a damascene element. The body is deformable by pressurizing fluid within the body between a first extended state and a second contracted state in which the axial length of the body is reduced and the internal volume is increased compared to the first normal state. The tessellation element may include a series of projecting and intruding structures arranged such that the body remains substantially cylindrical by deformation between its normal and deformed states. The protruding and intruding structures of the tessellation element may be in the form of a protruding pyramid and an intruding pyramid.

Description

Background technique [0001] The present invention relates to a collapsible device, more particularly but not exclusively to a collapsible device comprising a cylindrical pressurized shape. The retractable device is typically a fluid actuator, pump or compressor. [0002] Fluid actuators, pumps and compressors are devices that convert between energy in the form of a change in volume of a pressurized fluid and energy in the form of mechanical force and displacement. Fluid bellows and McKibben actuators are examples of such devices. Fluid bellows are structures composed of substantially non-stretchable and fluid-impermeable materials formed to favor small local deformations as internal fluid pressure and volume changes result in large global displacements. Bellows actuators, pumps and compressors are designed to extend axially almost exclusively under positive internal fluid pressure. In contrast, McKibben actuators contract when subjected to positive actuating fluid pressure,...
