ABSTRACT:
An actuator, designed to be used in a pressurized enclosure, creates a relative movement between two parts, in response to a variation of hydrostatic pressure. The actuator includes a closed-cell foam block fixed to the two parts. The actuator may be used in the deployment of wheel units and antennas inside a cavity formed by a tire and a wheel rim.
