摘要

Improvements in automatic systems for water renewal and cleaning services of airplanes in airports, of the type applied to aircraft service vehicles of airplanes in said airports, characterized in that a couple of solenoid valves are provided to operate the loading and unloading of water and detergent from the airplane, a pair of solenoid valves to operate the rise and fall of an operation and contact platform disposed on the vehicle, an electrovalve to operate the oil discharge from the hydraulic circuit to a tank, a pair of solenoid valves for use of the disinfection circuit and the circuit water and a solenoid valve for actuating the double acting cylinder, which in turn drives a reversible pump, these solenoid valves being operated automatically from a dashboard located on the platform, by means of manipulators for raising and lowering the platform, a circuit selection manipulator of water, a manipulator for selecting the disinfectant circuit, an aircraft loading manipulator and a discharge handle for hoses, which act selectively on a plurality of relays arranged in a maneuver cabinet, selectively feeding the coils of said electrovalves, which perform the maneuver chosen by the manipulator, being equipped in addition with a maneuvering safety device connected to the handbrake of the vehicle, as well as a level warning device in the sewage tank, interconnection, signaling, interruption and protection devices.
