  • the system is additionally equipped with a control cabinet, which is also made entirely of transparent material and located outside the container.
  • the control cabinet has a bolted front access cover, also made of transparent material. Through this control cabinet pass the intake, supply and drainage pipes, having in their upper removable part, three holes - one for each of the mentioned pipes - with rubber bushings, to protect, isolate and adjust the entrance of these pipes, and at the bottom, holes with rubber bushings to protect, insulate and adjust their output.
  • control and distribution panels In this cabinet are located several control devices for the intake and supply operations [with regard to the electrical part: control and distribution panels; wiring circuit of mechanical level sensors, solenoid shutoff valve, drain pump, supply pump, pushbuttons, timer relay, selector switch, LED lights and value recorder; for the devices themselves: drain pump, supply pump, pushbuttons (operation and drain), solenoid shutoff valve, timer relay, piloted shutoff valves, one-way valves, value recorder, hose receptacle supply, etc.].

  • the selector valve located externally to the vessel, underlying the base of the vessel, connects to it through holes, properly quantified, sized and positioned to ensure proper fuel flow as well as perfect switching operation between compartments, ensuring them individual or simultaneous flow, both on admission and exhaustion.
  • This selector valve is mechanically switched by a linear motor (through the axes of both motor and valve, which are fixed parallel to each other), and such linear motor, coupled directly to the valve housing, is endowed with excellent precision in its pre-programmed stationary positioning (maximum range +/- 0.05 mm) has velocity (at 48 VDC, 4m / s; at 72 VDC, 6m / s) and precisely defined accelerations ideal for (axial) motion of the shaft, as well as the proper actuation force for the application required here.
  • the drives (both intermediate and end-of-axis positions) of this linear motor are driven by signals sent by maximum and minimum levels, bringing - in all the applications necessary for the perfect and safe operation of this system, object of the present patent - total control over the fuel flow. There is, of course, no selector valve in case the container has only one compartment.
  • the container is also provided with a filter / breather system and a safety valve, both located on its top or on the container lid itself.
  • the filter / breather system is a set where the breather serves to allow the fuel to flow freely through the container - expelling internal air during intake and allowing external air to be exhausted during exhaustion - and the filter, Directly coupled to a compartment with activated silica gel or alumina, serves to prevent the entry of dust or impurities and ensure that the humidity does not exceed its ideal limit inside the container.
  • There is only one container filter / breather system even when it is a multi-compartment container, as in this case the separator plates (or separator plate for only two compartments) of the compartments have an opening - between the edge. top of each plate and the lid of the container - narrow but sufficient, thus interconnecting all the compartments from the top.
  • the safety valve In the case of the safety valve, it exists in the event that during the process of fuel inlet in the container some failure occurs in the other elements that automatically stop the intake pump. In this specific case, the actuation of the safety valve opens the electric circuit of the inlet pump, causing the related process to be interrupted immediately. It is noteworthy that the safety valve has a reset button, whose activation can only be done by technical personnel, because the operation of this valve necessarily indicates a defect in the system, which implies its immediate impediment. The availability of the system will only be possible again after its examination and consequent repair of the defect, to be performed only by a technically qualified professional.
  • the fuel flows from the main tank of the fuel dealer to the system container object of this patent. If you have a multi-compartment container, fuel passes through the selector valve.
  • the inlet system comprises, in addition to the selector valve itself (if multicompartmental), of transparent tubing, inlet pump, a piloted valve, a one-way valve, a manual shut-off valve and a filter flowmeter. Fuel only passes through the selector valve, as described above, if the container is multicompartmented. If the container consists of only one In this compartment, the fuel will flow directly from the main tank of the station to the container, passing through all the elements mentioned, except for the selector valve, which will not exist in this case.
  • the fuel will be introduced into it (until the level reaches the minimum operating limit in all compartments - bottom demarcation line) with the selector valve in its "general" position (this being the position in which all compartments are simultaneously interconnected through it, ideally the "general" position should be the last switching position of this valve, because of the simultaneous flow of fuel, this position provides - in addition to greater operational control speed in intake and drainage - that there is always the movement of fuel between all compartments, thus preventing decantation from forming at the bottom of each compartment - which, simply put, means: fuel always renewed in all compartments).
  • the selector valve is immediately switched to its 01 position, continuing with the intake until the container is technically (we will explain later) with enough fuel to meet the volume requested by the customer (although it does not necessarily have to be therefore, it seems ideal that the number of the selector valve switching position is always correlated with that of the compartment, so we suggest that position 01 of the selector valve be correlated with compartment # 1 - so we have previously suggested that the "general" position the last one). Once this is done, the system is now ready to start fueling.
  • the selector valve will be switched to the second, and - if the vessel has more than two compartments. - successively, until the sum of the compartments used for this specific service is sufficient to meet the amount requested. It is clear, however, that if the volume requested by the customer is greater than the sum of the maximum operating volumes of all compartments (ie the largest of the maximum operating volume of the container), the process of supply will proceed automatically, with the system taking over as new volumes of fuel are needed in the container until such care is fully met.
  • the number of selector valve changes will always depend on the number of compartments of the vessel, the individual volume of each of these compartments and, of course, the amount of fuel requested by the customer.
  • the so-called intake pump in this case, is the pump, directly connected to the main tank of the station, which removes the fuel stored there and sends it to the intermediate system container, object of this patent.
  • the container has only a single compartment, we may consider the container itself as the "limiting compartment" for any service.
  • the customer places (or records, in the case of self-service) a cash order corresponding to 15 liters of fuel and the system is at its minimum operating level (meaning that the compartments are all at the fuel level).
  • the procedure is as follows: it enters the cash value (or fuel volume; this is optional) into the cash register and activates the operation button, which causes that value to be "memorized” and "zeroed” by the system and turns on the intake pump.
  • the operation button causes that value to be "memorized” and "zeroed” by the system and turns on the intake pump.
  • the operating pushbutton which has an integrated color LED light, will have such a light on when the fuel in the limiter compartment has reached its maximum operating limit, at which point the maximum level sensor in that compartment shuts off the intake pump and starts the pump. of supply. It is important to note that although the customer's request in the hypothetical example was 15 liters, 20 liters will be pumped - above its minimum operating level - into the container.
  • the definitive or transitory interruption of the supply occurs by deactivating the supply hose nozzle trigger, either automatic deactivation (due to the Venturi device, located in the supply hose nozzle itself, or by the command of the value register indicating that the value entered has already been fully passed to the customer's vehicle tank - interruption by the solenoid shut-off valve, as explained below) or manually triggered (in this case, customer or operator deactivating the trigger located at the supply due to transient shutdown necessary or simply to the customer's wish to change the supply value to lower).
  • automatic deactivation due to the Venturi device, located in the supply hose nozzle itself, or by the command of the value register indicating that the value entered has already been fully passed to the customer's vehicle tank - interruption by the solenoid shut-off valve, as explained below
  • manually triggered in this case, customer or operator deactivating the trigger located at the supply due to transient shutdown necessary or simply to the customer's wish to change the supply value to lower).
  • the supply is automatically interrupted by the action of a solenoid actuated shutoff valve located between the supply pump and the value register.
  • the operation button will then have its color LED light turned off.
  • the solenoid shut-off valve to be released again, it will be unconditionally required that there be a signal command sent by the limiting compartment level sensor corresponding to a new request, a command that will obviously occur only after the entering a new value in the cash register and, in a natural sequence, the completion of the entire admission process for the container (as the admission process always precedes the supply process, as has been said).
  • the full volume initially requested by the customer although the supply pump is still on, can only be continued when a new value is entered into the value register - which in practice It also means a new service, even for the same customer.
  • Supply pump shutdown occurs only when the supply hose handle is replaced in its receptacle; At that time the supply is considered to be closed.
  • the sum, daily, weekly or monthly, of the volumes supplied through the system object of this patent can naturally have its value stored in the totalizer (already existing in the current systems of the gas stations). that is, by removing it (to the totalizer), in terms of the electrical circuit, from its present position and inserting it, in the same terms, into the supply circuit of the system object of this patent.
  • the function of the timer relay (we will discuss in more detail below) is to automate the total drainage process of the system.
  • the system is considered completely drained when all the fuel in the container is returned to the main tank of the station, which occurs automatically (after time to be determined later) or manually (by actuation of the drainage button).
  • the drain pipe is also transparent and has a flow-through filter screen. If there is a new request in a short time (defined later), that is, before the timer relay activates, the process will be repeated normally, but the previous drainage occurs (as soon as the operator - or the customer - enter new value of the 5 liters left in the container from the previous supply (remembering: in the hypothetical example used, the operating volume of compartment no.
  • the remaining fuel will drain through the selector valve in its "general"position; immediately after draining (only up to the minimum operating limit, ie normal drainage), the required new fuel volume will be admitted (in this case, as the fuel level after draining is already at the lower limit of operation, the selector valve will have been switched from its "general" position to its 01 position and will continue to be admitted from compartment no. 1 onwards (if applicable). As soon as admission ends, the system is ready for further service. All processes take place in very short time, due to the pumps for each of them.
  • the container may be constructed to any shape or volume desired and, as stated above, may also have any number of compartments desired, provided it is made of material compatible with its content and above all transparent.
  • the control cabinet which can be any size, any shape, and made of any material as long as it is transparent, and such attributes and characteristics must necessarily be compatible with the system's needs for effectiveness.
  • the central idea of the system presented here is - and nothing more - exactly to guarantee the customer one of his most legitimate and sacred rights: to be sure of what he buys. And such a goal is only achieved through total transparency.
  • Multicompartmentation and control elements both in quantity and quality, have the primary function of adding greater technical value to the system.
  • the selector valve if any
  • the station tank - it consists of an axial drainage pump, a one-way valve, a piloted valve, as well as - as stated above - clear tubing and a filter flowmeter.
  • the drainage occurs whenever there is a supply request (this, if the drainage has not already occurred due to the actuation of the timer relay), causing the remaining fuel level in the container to always return to its minimum limit. hence the requested volume (entered in the cash register by the customer or operator) is admitted to the same container.
  • Such operation is automatic, necessary for the effective operation of the system presented here, and occurs only with the selector switch (not to be confused with the selector valve) in position 01 (or position " ⁇ " - “automatic") - which is, in short , the position to be maintained during normal system operation.
  • the position 02 (or position " ⁇ " - “manual") of this same selector switch causes the drainage only to occur if it is provoked (desired), which is done by activating the drainage button (which also has colored LED light which remains lit during drainage, whether automatic or triggered).
  • the "manual" position of the toggle switch is used to enable preventive or corrective maintenance of the system.
  • the system also has a timer relay which, according to necessity, convenience, determination or standard, will cause the drainage pump to start automatically after the system has been unused for some time. Such time interval will therefore be regulated in the timer relay according to the priority situation among those mentioned above.
  • the total number of sensors per container therefore extends the number of compartments per container.
  • Each container also has a single densimeter, with a very small internal volume, located adjacent and external to the first (or only, if only one) compartment, connecting the densimeter to the lower interior of this compartment through small tubing, having such location and insertion the objective of gauging, in real time, any amount of fuel inserted in the container. Therefore, the contact of the densimeter with the fuel occurs as soon as it begins to be introduced into the container. There is no need for more than one densimeter per container because, as already mentioned, the inlet, which is made from the main tank of the station to the container, is primarily for all compartments, at which point they are all interconnected.
  • the said container (multicompartmental or single compartment) is therefore in an intermediate position between the main tank of the gas station and the tank of the vehicle.
  • the internal multi-compartmentation of the container is intended to enable the customer to further visualize (gauge) the requested and subsequently admitted and exhausted fuel volume of the container, thereby increasing , especially, the easy visual perception of the variation between quotas as the fuel is exhausted or admitted (or - because the ruler is multigrade - any units of measurement considered preferable, by use and custom, to the location; these will always be placed side by side with each other on the ruler, the first of which may be, for example, in liters, all of which, in parallel graduations, have exact proportional relations with one another.
  • the measurement of the volume supplied is then simple reading of the value visually observed in the multigrade ruler of the so-called "limiting compartment" for that service, and no account is required to reach this amount, since the total volume supplied is the one that reads directly on the ruler of that limiting compartment, or that is, at the level where the remaining fuel is in it (if any) - although we think it is important to note again that this reading corresponds to what the customer really wants to know: the volume transferred to the tank of his vehicle.
  • the fuel will be sent from the gas station tank first to the container (multi-compartment or not), and then the fuel volume requested by the customer will be transferred to the tank of your vehicle.
  • the payment of the refilled volume is made: the customer service is then terminated. It is never too much to repeat: such a process, because of its total transparency, is the only one that can give this same client - usually layman and generally not very sure about sophisticated measuring equipment - confidence and absolute certainty to be able to perform in time. the measurements repeatedly cited here: the quantity and quality of the fuel.
  • the system object of this patent may have a multicompartmental container or a single compartment container - thus being considered “multicompartmental" when the container has two or more compartments.
  • a switching device from one compartment to another (selectivity, which occurs by means of a flow selector valve), both inlet and inlet.
  • switching occurs when the minimum operating limit of a particular compartment is reached, causing fuel to be exhausted from the next compartment.
  • Analog switching (and performed by the same selector valve) also occurs on intake; This occurs when the maximum limit is reached for this same compartment (ie during the previous filling of the container with the fuel coming from the main tank of the fueling station).
  • the selector valve located at the base of the container, covers all compartments, such valve having a number of switching positions equal to the number of compartments plus one. Except in the case where the container has only one compartment, if, for example, the number of compartments is n, the number of valve switching positions will be n + 1. That is, if there are three compartments, as n equals three, then the selector valve will have four (three plus one) switching positions. Valve switching is controlled by level sensors installed in the vessel compartments and located over the upper and lower boundary lines of each compartment. Each compartment is therefore equipped with two sensors. Such sensors control the maximum and minimum levels of operation.
  • the maximum and minimum levels of system operation are marked by horizontal and highlighted lines located on the outer wall of the container; the sensors that control these two levels are installed on these lines, ie the minimum level sensors are exactly the same height as the minimum operating line; the maximum level sensors at exactly the same height as the maximum level line of operation.
  • the minimum level such a prominent line is located just above the base of the container.
  • the highlighted line is located just below the top.
  • the upper limit is just below the top so that there is room for the safety valve float and comfortable positioning of the top level sensors (in addition to the upper interconnecting space of the compartments, such space being between separator plates). and top, in this case, a narrow opening range, but sufficient for its function).
  • the lower limit is just above the base to similarly make room for comfortable positioning of the lower level sensors, as well as reassuring the customer that there is no surplus with respect to their purchase of fuel in the container.
  • the purpose of the system object of this patent is to intermediate the transfer of fuel from the fuel station tank to the customer's vehicle tank; Therefore, it is necessary first to have the requested volume (partial or full) in the container, and only then to send it to the tank of the vehicle.
  • the intake process from the main tank to the container, if it is multicompartmentary, also takes place through the same selector valve. During the intake process, this first occurs with the selector valve in its last switching position, ie in the switching position where all compartments are interconnected through that valve.
  • the selector valve is immediately switched - by means of a command made by the minimum level sensor - to position 01 , ie position where only the first compartment is now connected to the intake system, filling this compartment until the fuel reaches its maximum level (as noted above, a prominent line located just below the top ).
  • the maximum level sensor in this compartment sends a command signal to the selector valve, switching it instantly to position 02, position where only compartment # 2 is connected to the intake system.
  • the maximum level sensor in this compartment sends a command signal to the selector valve, switching it instantly to position 03, position wherein only compartment No. 3 is connected to the intake system, and so on, where appropriate, by action of the respective maximum level sensors for the following compartments to the last compartment.
  • the selector valve will not be switched to the next compartment and, at the exact moment the sensor is activated, the intake will be interrupted. (here understood: the volume requested by the customer is exactly equal to the operating volume of one compartment or equal to the sum of the operating volume of two or more compartments. For example, a container with four compartments of 20 liters each, and the customer order is exactly 60 liters, in this hypothetical case, the limiting compartment is the third).
  • the electro / electronic circuit keeps its maximum level sensor non-operative with respect to valve switching (but operative with respect to inlet pump stop). This is due to the electro / electronic control system, which is designed to ensure that the triggering of the level sensors is in perfect correlation with the order, ie, directly related to the value entered in the value register.
  • the admission level will reach its maximum limit. This is because never any compartment during the admission process is less than full. This is because the admission process will only be interrupted when the limiting compartment level sensor is activated (compartment that is "limiting” precisely because, according to the value entered in the value register, it "recognizes” it as such) , which in this case will send a command signal to the intake pump shutdown (which will occur via the pump contactor switch).
  • the level sensors have several functions, among them, besides the valve switching function, the command to stop the intake pump.
  • the upper limit - where the level sensor is located - must be reached so that it can play its role in controlling the operation of the system. That is to say, never is any compartment (only during the admission process) partially filled with fuel; every compartment used for Completing the requested volume is always filled up to its maximum G, operation.
