A washing unit for turboprops of aircraft is disclosed, which comprises a hydropneumatic accumulator suitable for supplying, at a controlled pressure, a washing fluid contained therein, and a filling member, motorized and manual, for feeding the washing fluid into the accumulator. The accumulator may be connected alternatively to the motorized filling member or to the manual filling member. A manually actuated device is also provided for pressurization of the accumulator, so that the washing unit can be used both in areas equipped for this operation and in areas not so equipped.

1. A washing unit for turboprops of aircraft, the unit comprising a hydropneumatic accumulator suitable for supplying washing fluid contained therein at a controlled flow rate and pressure, a motorized filling member and a manual filling member, for feeding the washing fluid into the accumulator, which may be connected alternatively to the motorized filling member or to the manual filling member, a manually actuated device also being provided for pressurization of the accumulator, such that the washing unit can be used both in areas equipped for this operation and in areas not so equipped, wherein the hydropneumatic accumulator includes a tank divided into a first and second chamber by an elastic membrane, the washing fluid being contained in the first chamber, the first chamber being configured so as to be connected hydraulically to the motorized filling member or, alternatively, to the manual filling member, through a connector, the washing fluid being delivered to the first chamber from the connector via a filling conduit connected to a valve and a second conduit connected between the valve and the first chamber, the second chamber containing a pressurization fluid, the second chamber being configured so as to be connected pneumatically to a motorized pressurization member or to a manual pressurization member, whereupon feeding of washing fluid into the first chamber causes an increase in pressure of the pressurization fluid in the second chamber up to a predefined value, such that the washing fluid is supplied through the second conduit and valve to a delivery conduit to supply the washing fluid. 2. The washing unit set forth in claim 1, further comprising a transportable box-shaped frame wherein the hydropneumatic accumulator and the motorized filling member are placed. 3. The washing unit forth in claim 1, wherein the manual filling member comprises a manual pump. 4. The washing unit set forth in claim 1, wherein the manually actuated pressurization device comprises a pneumatic pedal pump. 5. The washing unit set forth in claim 1, further comprising a kit of accessories for carrying out washing in areas not equipped for operation, which kit includes a manual pump, a pneumatic pedal pump and an accessory for depressurization.
