Abstract
An extendable pressurized fluid coupler is disclosed. The extendable pressurized fluid coupler has a guiding portion having a central fluid channel. The extendable pressurized fluid coupler further has a piston having a central fluid channel, the guiding portion and the piston having a common central axis. The extendable pressurized fluid coupler also has a drive circuit for driving the piston. The piston is extendable with respect to the guiding portion. The guiding portion is arranged for guiding the piston along the central axis. The piston is arranged for connecting the pressurized fluid coupler to a corresponding coupler having a second fluid channel, so that a fluid passage for a main pressurized fluid circuit is established.
