    "Water projection control system in nozzle assemblies for vehicles" which includes electronic control by automaton, which regulates and blocks the positions of the diffuser until the nozzle sections are adjusted.
    As a joint analysis of the proposals that make up the state of the art, if we focus attention on tank vehicles operating at low pressure, they meet the needs of the service sector, but with clearly improved productivity.
    In response to tank vehicles designed for medium pressure operation:
    A. The functionality for "manual sweeping" operation is not addressed. Likewise, for "short" jobs, the need for grouping dirt into piles has not been resolved. Presenting, the current systems, the problem of dirtying vertical elements such as shop windows, facades, furniture and vehicles. Remaining, ace! same, very scattered auctions, so they need more dedication of the sweeping operator.
    B. On the functionality for the operation of "mechanized scanning", the proposed invention, improves the solutions currently applied, by improving the way of applying the water jet through its section, position and pressure, achieving a better result , with greater reach and productivity.
    C. Finally, with respect to the rest of the functionalities such as irrigation, beading, washing and descaling, the proposed invention represents an improvement over the current state of the art, based on the fact that the configuration and structures designed present a substantially installation. simplified when operating on a single pressure pump, capable of servicing the aforementioned functions with an improved result by increasing water pressure.
    According to the equipment of the said tank vehicles, the state of the art in the field, provides various solutions for the same needs using different implements, devices, regulation and control systems, pressure pump and cooling pump actuation systems the motor. In summary, the possibilities of this tank vehicle in the fields of application referred to above based on the deficiencies and inconveniences listed below are not resolved:
    A. They have a significant loss of body volume, as a reserve for water loading, which also increases the TARE, both in the case of the electric flusher and in the soundproof auxiliary motor.
    B. The operability of the equipment, and therefore its functionality, is conditioned to the skill and aptitude of the operator driver. When you need selection of orientation, height and section of the injectors or water pressure. In other words, in the proposal of the present invention the optimum operability of the vehicle is guaranteed, as it has the predefined functionalities and does not depend on the skill and good aptitude of the operator.
    C. Environmental impact clearly improved. Since the proposal object of the present invention forms a better energy solution (lower water consumption), CO2 emission (the auxiliary engine is suppressed, the pump works with the vehicle's engine at idle speed) and noise (engine at idle speed) The transmission and water pressure pump operates at low rpm, simple (lower components), and therefore, with less maintenance and more reliability with less investment.
    D. The specific applications that precede the present invention for mechanized scanning or manual scanning do not explicitly solve the needs of their users or are clearly improvable.

    Then, by way of conclusion, the “Multiple services tank vehicle for mechanized sweeping and manual sweeping”, provides a unique bodywork of simple and reliable design that operates through a single water pump without auxiliary motor in which the loss is minimized of payload, while the management of control and command of the said single pump through its rpm, is accurate and stable. Thus, for the election of the different functionalities and its communication with the electronic management of the vehicle, it incorporates programmable automaton, which provides for each functionality the option of adjustment to three power levels. That is to say, by modifying the programming of the automaton, it is possible to define the adapted services the preferences of the client, without transformations or modifications.
    EXPLANATION OF THE INVENTION
    As an explanation of the "Multiple services tank vehicle for mechanized sweeping and manual sweeping", it is carried out based on the integration of the following circuits;
    A. Oil-hydraulic force transmission circuit
    It is made up of the variable flow pump mechanically coupled to the kinematic chain of the tank vehicle that feeds through the variable flow distributor to the hydraulic motor. The latter, coupled to the mechanical transmission, drags the piston pump of the flushing service. The circuit is complemented by an oil tank, cooler, filter and protections.
    B. Electronic communication, protection and command circuit.
    It is made up of a console or control panel in the cabin, which manages the electronic control unit (ECU), installed on a low-voltage hermetic cabinet that controls the proportional distributor, the water pressure pump and the distribution manifold for the choice of selected service.
    C. Water circuit for washing.
    It is formed by the inlet line from the tank of the vehicle, to the water pressure piston pump that feeds the distributor manifold, in which the service to be provided is selected by solenoid valves.
    The previous scheme complemented with the corresponding accessories must display the following functionalities or modes of operation:
    Irrigation functionality
    It is used for fixing the dust on the road and cooling the environment during hot times and situations. The vehicle works in displacement and with only one operator, and at a speed close to 20 km / hour. The cistern vehicle incorporates a water conduction from the pump, which feeds a rear bar with a series of injectors with diffuser conical jet, working with the lowest pressure, around 10 bars and with a sufficient flow to leave the road sufficiently wet . The pressure of incidence of water on the ground must be minimal, what matters is the dispersion and the discharged liters per square meter.
    Wash and wash functionality.
    It is used for cleaning roads and sidewalks by dragging dirt over short distances. When carried out with high flow, it gives the result with the quality of the irrigation functionality. They are the ones that currently have the state of the art resolved. They are solved with vehicles designed in low pressure. They are functionalities that tend to disuse due to insufficiently productive and excessive water consumption.

    The present invention makes this functionality possible with the same circuits and implements as for mechanized and manual scanning, only increasing the R.P.M. to increase the flow and replacing the injectors with others of more section, to decrease the pressure.
    Functionality of descaling with scanning.
    It is used for cleaning roads with mud and mud, coming from streams with trawls, and in the exits of sites in works, dirty by the filming of work vehicles. The vehicle works in displacement, with only one operator and at a speed of less than 20 km / hour. The tank vehicle incorporates a water conduction from the pump, which feeds two front bars with a series of injectors with jet at an angle, working with the highest pressure, around 100 bars. What matters is the impact pressure on the ground that should be as high as possible and in the form of a continuous blade across the entire width of the vehicle. To achieve this, the injectors will be angular, will be as short as possible from the roadway and with an angle of incidence of the water jet in depression at 80 °. The two bars will be oriented with a certain angle to the advance of the vehicle in about 40 °, to give out to the descaled waste.
    Mechanized scanning functionality.
    It is used for the cleaning of roads by dragging the dirt by water jet and the grouping of linear form on the curb with long ranges. The vehicle works in displacement, with a single operator and at a speed close to 20 km / hour. The tank vehicle incorporates a water line from the pump, which feeds 4 units of water nozzles with straight jet, that is, without deformation and without air injection. The injectors are mounted in a transverse line to the vehicle, the water jets work transverse to the vehicle's progress. Working with the optimum pressure to the type of dirt, up to 100 bars. Operating in different combinations, from one jet to four, giving a possibility of combinations up to 24, depending on the type of road, road width and sidewalk and position of car parks. What matters is that the water jet has the proper shape and pressure to the weight of the residue, to be able to move it along the curb. For this, the appropriate power level of the three possible ones is selected. The water jet is almost parallel to the roadway, with an angle in depression up to 15 °, the injector is mounted on a retractable support, and flexible to avoid deformation by impacts. You can incorporate a skid or wheel to protect it from bumps and potholes.
    Manual scan functionality.
    It is used for cleaning sidewalks and plazas by dragging dirt by water jet and grouping in the form of heaps. The tank vehicle incorporates a water line from the pump to a beam and to a rear reel, with a hose section rolled. Thus, with the beam it is possible to use it in short spaces (sidewalks) and with parked vehicles, while with the rear reel, greater scopes are achieved, making it possible to clean places. It is coupled to a water jet applicator tool, to perform the manual sweep and on the basis of which the operator carries out the cleaning once the hose is unwound and the pump is pressed, with the vehicle engine running. . The operator in the operation of the drag of the dirt, projects the water jet at the maximum design pressure, close to 100 bars.
    Alternatively, the dirt is grouped in piles, by another water jet at the minimum design pressure, close to 15 bars and in the form of a cradle, which facilitates the dizziness of the water jet in the operation of grouping the dirt in

    lots. For this, the vehicle must move with short and alternative advances, depending on the advance of the cleaning front of the auxiliary operator. With this mode of operation, a greater performance of the water capacity of the tank is achieved, reducing the number of water loads and therefore avoiding the unproductive times of the operator's equipment.
