<p>A pressurized fluid device for operation of a device by generation of a desired pressure in a fluid in the cylinder space (70, 72) of a cylinder such as a double-acting servo-cylinder. The pressure is a function of a signal emitted via an operated device. A fluid pump (74) is supplied with the fluid from a reservoir (20) and delivers the fluid to the cylinder spaces (70, 72) via respective magnetic valves (80, 82) with two operational positions. A computer (58) controls the magnetic valves (80, 82) and is arranged to receive the signal. Pressure sensors (92, 94) are arranged to establish the fluid pressure in the cylinder spaces and transmit corresponding electrical signals to the computer (58). On the basis of the received signals the computer is arranged to transmit electric signals to the magnetic valves (80, 82).</p> |
