A fully-integrated, flow-control module for top-fill fuel tanks is designed to operate with a fuel line attached that supplies fuel under constant pressure. A main flow control valve within the flow-control module closes automatically when the fuel tank is full, and automatically opens when the fuel level drops a certain amount below the full level. A spring-biased valve plunger of the main flow control valve has a bleed aperture that diverts a small amount of incoming fuel to a bleed path that is controlled by a fuel level float that operates on a lever arm that either opens or closes the bleed path. When closed, fuel pressure beneath the valve plunger increases sufficiently that the plunger biasing spring is able to exert a force sufficient to close the valve plunger. Bleed path control hysteresis prevents rapid cycling of the main flow control valve.

A personal vaporizer has a hollow tube that extends from an atomizer through a tank for holding vaporization media. The hollow tube has a filling hole formed through a side wall thereof. To fill the tank, vaporization media can be injected into a mouthpiece and flows into the hollow tube. A divider wall in the hollow tube deflects vaporization media through the filling hole and into the tank. After the tank is filled with vaporization media, vaporizer is moved to an assembled configuration in which the filling hole is blocked.

A method for determining a filling stop during a filling process of an operating fluid container whose operating fluid container interior can be filled with an operating fluid via a filling pipe opening into said interior, wherein a pressure sensor for determining a pressure within the filling pipe is arranged in the filling pipe, wherein the method has the following method steps: acquiring the time profile of pressure values acquired by means of the pressure sensor; and outputting a filling stop signal in accordance with the time profile of the pressure values. In addition, the present invention discloses an operating fluid container system having an operating fluid container and a filling pipe, opening into an operating fluid container interior, for filling the operating fluid container with an operating fluid, wherein the operating fluid container system has a pressure sensor arranged within the filling pipe and is coupled via a data line to an electronic control device for transmitting data, representing the pressure within the filling pipe, to the electronic control device, wherein the control device is designed to carry out the method according to the invention for determining a filling stop.

A method and a system are disclosed for filling an LPG tank equipped with a spit valve and a fill assembly, the method comprising providing an indication of a level in the LPG tank upon detection of a filling vehicle in a vicinity of the LPG tank, the filling vehicle having a filling hose; initiating a filling of the LPG tank once the filling hose is connected to the fill assembly of the LPG tank; determining when a current level reaches a given level in the LPG tank and stopping the providing of the LPG to the LPG tank once the current level reaches the given level in the LPG tank.

An automated diesel exhaust fluid (DEF) system and method for refilling DEF. The automated DEF system provides DEF refilling after an initial setup and without manual intervention. The automated DEF system includes a electric DEF flow control device that controls the flow of DEF. The electric DEF flow control device may include control circuitry, an electrics enclosure that encloses the control circuity, an electric fluid sensor, a valve, a beacon light, a status light, a button, a threaded swivel connection, and a mandrel on the inside of the threaded swivel connection.

A product system for an agricultural sprayer includes a product tank configured to store an agricultural product. A reclaim system can be configured to provide the agricultural product within a flow assembly to a product tank. A computing system can be communicatively coupled to the reclaim system. The computing system can be configured to receive information indicative of one or more characteristics of the agricultural product inputted into the fill station during a fill mode; detect termination of the fill mode; and activate a reclaim mode to move the agricultural product from the flow assembly to the product tank through activation of the reclaim system, wherein one or more operating conditions of the reclaim mode are based on the one or more characteristics of the agricultural product.

An agricultural method for preventing roll-back of an agricultural vehicle may include receiving a roll-back prevention input from a speed setting device indicative of a command to increase the transmission speed of the hydrostatic transmission while a service brake of the agricultural vehicle is engaged. Further, the method may include adjusting a speed mapping for the speed setting device from a predetermined speed mapping to a roll-back speed mapping in response to the roll-back prevention input, with the roll-back speed mapping being associated with a reduced speed range. Additionally, the method may include determining a transmission control command associated with a current position of the speed setting device based on the roll-back speed mapping and controlling an operation of the hydrostatic transmission to adjust the transmission speed based at least in part on the transmission control command.

A product delivery vehicle system includes a product delivery vehicle with at least one tank compartment. The system includes an internal valve fluidly coupled to the tank compartment, a control valve, and an air system comprising a main air valve and a solenoid valve fluidly coupled to the main air valve and to the internal valve. The solenoid valve is operable to open and close the internal valve. The system includes an electronic control unit communicatively coupled to the control valve, the main air valve, and the solenoid valve. The system includes a tank tag reader operable to read a tank tag and transmit a tank tag indicator associated with the tank tag, the tank tag indicator indicative of a stored liquid type in a distribution tank. The electronic control unit may maintain the internal valve closed and the control valve locked when a product type mismatch is detected.

An overfill valve associated with a drop tube segment fluidly connected to a fluid reservoir is described. The overfill valve includes a valve body positioned within the drop tube segment and a non-contact valve actuator positioned exterior to the drop tube segment and operable to actuate the valve body from an open position to a closed position without requiring any physical penetration through the wall of the drop tube segment. The non-contact valve actuator has a first position in which the non-contact valve actuator does not actuate the valve body from the open position to the closed position in a second position, achieved when the liquid reservoir reaches a predetermined level approaching the capacity of the liquid reservoir, the non-contact valve actuator actuating the valve body from the open position to the closed position when the non-contact valve actuator obtains the second position.
