Definitions
- the field of the present invention relates generally to fuel dispensers, and more particularly to vapor recovery systems for use when dispensing a volatile fuel such as gasoline.
- the volumetric flow of a vapor recovery means is controlled by programmed micropressor means. Electrical signals are derived that are related in a known way to the volumetric flow of the fuel delivery means and applied to a microprocessor. The microprocessor then determines on the basis of information stored therein the parameters of an electrical signal that can be applied to the vapor recovery means so as to make it have a desired volumetric flow.
- the volumetric vapor flow can be controlled by adjusting the speed of the motor for the recovery pump contained in the vapor recovery means, by changing its displacement or by controlling the position of a valve or damper in response to the signal from the microprocessor.
- a stepping motor drives the pump for the vapor recovery means
- the microprocessor controls the repetition rate of the drive pulses supplied to the stepping motor so as to cause the recovery pump to have the desired volumetric flow. If a different recovery pump or motor is used that requires drive pulses having a different repetition frequency to produce the desired volumetric flow, it is only necessary to make a slight change in the program controlling the microprocessor.
- volumetric flow of the vapor recovery means may be set equal to the volumetric flow of the fuel delivery means
- there are some conditions such as a difference in the temperature of the fuel in the vehicle tank and fuel from the supply tank under which it is desirable to use a volumetric vapor flow that is different from the volumetric fuel flow.
- an indication is derived as to the volumetric vapor flow, and the microprocessor compares this indication with a value of vapor flow that is normally expected and makes the required adjustment.
- a transducer generates an electrical signal correspondling to the hydraulic pressure at the inlet side of the pump for the vapor recovery means.
- the pressure will have a desired nominal value.
- the nominal pressure is restored by decreasing the volumetric flow of the vapor recovery means, and when it is greater than this value, nominal pressure is restored by increasing the volumetric flow of the vapor recovery means.
- the microprocessor is programmed to respond to the signal representing the pressure and provide signals for controlling the volumetric flow of the vapor recovery means. This is particularly easy to do if, in accordance with this invention, the motor driving the recovery pump is of the stepping type because it is driven at a speed determined by the repetition rate of drive pulses, and this can be easily changed.
- Vapor recovery systems constructed as briefly described above permit the attainment of faster fuel delivery and greater efficiency, and make it easier to handle the hose. Furthermore, expensive vapor processing units, which are required when the vapor and liquid volumetric flow rates are not the same are not required.
- FIG. 1 is a cutaway view of one embodiment of the present invention.
- FIG. 2 is a cutaway view of another embodiment of this invention.
- FIG. 3 shows the metering pulses used to indicate the volumetric flow of liquid being dispensed or delivered.
- FIG. 4 shows drive pulses used to drive the motor for the recovery pump.
- FIG. 5 is a flow chart illustrating the operation of the embodiments of FIG. 1 and FIG. 2.
- a hose 2 extends from a fuel dispensing pump housing 4 to a nozzle 6.
- the nozzle 6 has an outlet tube that is inserted in the inlet pipe for the gas tank of the automobile 8, and an accordion-like nose 10 that is coaxial with the inlet pipe forms a seal with the pipe so that any liquid and vapor that emanate from the pipe during the dispensing procedure will be conducted to a chamber or space 12 formed between a liquid delivery hose 14 and an outer hose 16 coaxial therewith.
- a liquid and vapor recovery tube 18 is inserted to an expected low point in the chamber or space 12 formed between the delivery hose 14 and the associated outer hose 16.
- the tube 18 has such a small internal diameter that vapor passes through it with enough velocity to entrain liquid fuel.
- the end of the hose 16 that is remote from the nozzle 6 is sealed at a coupler 20.
- the liquid or fuel delivery hose 14 and the vapor recovery tube 18 pass into the pump housing 4 through a wall 22 that seals the end of the hose 16, that is joined to the coupler 20.
- the liquid delivery hose 14 is connected to a flow meter 24 that is connected via a mechanical connection indicated by a dashed line 26 to a pulser 28.
- the speed of the flow meter 24 causes the pulser 28 to deliver pulses proportional to the volume of liquid flowing through inner hose 14 to microprocessor 34.
- the volumetric flow of a fuel delivery pump 32 that pumps fuel from a main supply tank, not shown, via a pipe 30 to the meter 24, is changed as the operator manually changes the opening in the nozzle 6.
- the pump 32, a motor 33 that drives it, and the manual control just described, constitutes a fuel delivery means.
- the vapor recovery tube 18 is coupled to the inlet side of a vapor recovery pump 36, and a transducer 38 produces an electrical signal indicative of hydraulic pressure at that point that is conveyed to the microprocessor 34. Vapor and liquid withdrawn from the chamber 12 via the recovery tube 18 and the recovery pump 36 are conveyed to the underground supply tank, not shown, via a tube 40.
- the vapor recovery pump 36 is preferably of the displacement type in which volumetric flow is directly proportional to the speed of operation.
- the pump 36 is mechanically driven via a shaft 42 by an electrical motor 44 that is preferably of the stepping type.
- the pump 36 and the motor 44 constitute a vapor recovery means.
- a drive pulse source 46 supplies drive pulses to the motor 44 at a repetition rate controlled by the microprocessor 34.
- the housing 4 is divided into upper and lower sections by a vapor barrier panel 48, and the only electrical component below it is the pressure transducer 38 that may easily be made explosion proof.
- FIG. 1 Before discussing how the embodiment of FIG. 1 operates, reference is made to the differences of a very similar embodiment shown in FIG. 2.
- the principal differences are that the coaxial hose 16 is eliminated so as to make handling easier and that both the liquid delivery hose 14 and the vapor recovery tube 18 extend to the nozzle 6.
- the nozzle 6 contains a chamber, corresponding in function to the chamber 12 of FIG. 1.
- the recovery tube 18 extends into the low point of the chamber, however formed, and sucks up any vapor or liquid therein.
- FIGS. 1 and 2 is as follows. Assume that the signal supplied by the pulser 28 is a series of pulses 47 as shown in FIG. 3, and that they have a repetition rate F proportional to the volumetric flow in the delivery hose 14.
- a series of pulses 49 shown in FIG. 4 have a repetition rate V that is equal to the repetition rate F.
- Pulses 49 are applied to the motor 44 for the recovery pump 36 so as to cause the latter to have the same volumetric flow for vapor and entrained liquid as occurs for fuel in the delivery hose 14.
- the pulses 47 and 49 could have different repetition rates for the same volumetric flow, in which case means for changing the repetition rate of the pulses 49 could be used or the microprocessor 34 could be suitably programmed.
- volumetric vapor flow greater or less than the volumetric fuel flow. If the temperature of the fuel delivered to the vehicle tank is the same as the temperature of the fuel in the vehicle tank, satisfactory operation may be attained by making the volumetric flow of the vapor recovery means equal to the volumetric fuel flow, but, if for example, the fuel in the vehicle tank is cooler, it will be warmed up as the delivery continues so as to produce more vapor than it would if the temperatures were the same so that the volumetric flow of the vapor recovery means 36, 44 should be increased. The inverse of this situation occurs if the temperature of the fuel in the vehicle tank is warmer than the fuel being delivered.
- a pressure transducer 38 provides a signal P corresponding to the pressure at the inlet of the vapor recovery pump 36.
- P would have a known nominal value X if the volume of vapors emitted from the tank equalled the volume of fuel being delivered, as might be the case if the temperature of the fuel in the vehicle tank and the fuel being delivered were the same. But, if the volume of vapor is greater than the volume of fuel being delivered, the pressure P would be greater than X, and conversely, if the volume of the vapor is less than the volume of the fuel being delivered, P would be less than X. Referring again to .[.FIG. 3.]. .Iadd.FIG. 5.Iaddend., we find the following.
- the recovery pump 36 is running too fast, and the repetition rate V of the drive pulses is reduced, for example, by one pulse a second, step 62, i.e. to (V-1).
- the repetition rate V is increased, for exampie, by one pulse a second, i.e. to (V+1), step 66, but if P>Y, the dispenser is shut down, via step 52. Thus if P>Y, the dispenser is shut down.
- the recovery pump could be driven by a D.C. motor rather than a stepping motorin which case the microprocessor 34 could be programmed to provide a signal that would select an appropriate one of a number of different D.C. voltages for application to the motor.
- the vapor recovery means 36, 38 could have a valve or damper that is controlled by the microprocessor 34 so as to suck out the desired volume of vapor.
- the center hose could be the vapor hose, and the space between the inner and outer hose can be used to convey fuel in a system including the invention.
