  • Patent number: 9327563
    Abstract: This invention describes a system to maintain equal pressure in a pair of dual tires, and also incorporates a valve mechanism that will prevent one dual wheel tire from going flat in the event the other dual wheel tire experiences a rapid air loss. Dual wheels are typically mounted on the vehicle hub with both wheel disc faces in direct contact with each other. To ensure equal pressure in both tires, this invention has air passageways machined into the wheels such that the air passageways meet at the interface between the wheels where the wheel disc faces are in direct contact. These junctions are sealed by a rubber seal or gasket. Both tires can then be inflated or deflated simultaneously through a standard air valve located on either wheel. Where a dual wheel arrangement requires the use of an intermediate piece between the dual wheels, air passageways can connect the two-piece wheels via intermediate air passageways going through the common intermediate piece.

  • Patent number: 7168415
    Abstract: A vehicle chassis with at least two fuel tanks with each of the fuel tanks having fuel level detector or sender. The level senders are engaged to an electronic controller. The individual tank draw lines from each tank come together at a control valve that has a single outlet that leads to an engine. The control valve can be open from one of the tanks at a time to the engine. An electronic controller takes the inputs from the fuel senders and compares levels between the tanks to control the valve. The system defaults or starts drawing from a primary tank and upon the level in the primary tank falling to a pre-specified amount below the level in a secondary tank, the electronic controller shifts the control valve to draw from the secondary tank or vice versa on a secondary tank level drop.

  • Patent number: 7121266
    Abstract: A fuel pump cutoff shuttle valve is located between a multiple fuel pump arrangement. The valve has a first tubular member with a hollow, biased sliding member inside that moves according to the fuel pressures of the pumps. The fuel that flows through the valve member passes out through a valve member central orifice so that the fuel can flow into the second tubular member en route to an engine. When the fuel pressure in a pump greatly exceeds that of another pump on the opposite side of the valve member, the valve member moves and places the valve member central orifice adjacent to the interior wall of the first tubular member, stopping the flow of fuel. Alternatively, the valve member may have an orifice at each end of the valve member to permit a reduced flow of fuel to the engine when fuel is not supplied by the central orifice.

  • Patent number: 6283142
    Abstract: A fuel system including first and second tank portions communicating with each other such that the first and second tank portions have a substantially equal vapor pressure, first and second fuel pumps in the first and second tank portions, respectively, and a crossover fuel line for transferring fuel in either direction between the first and second tank portions, the direction of transfer depending on the relative level of fuel in the first and second tank portions. Respective first and second shuttle valves control the direction of fuel flow through the single crossover line to maintain substantially equal fuel levels in both bifurcated portions until the tank is empty. First and second jet pumps communicate with the crossover fuel line and provide the suction needed for fuel transfer.

  • Patent number: 6260577
    Abstract: The dispensing assembly for transferring at least two liquid components from a remote source to a metering device and for replenishing component accumulators independently of whether the unit is metering or not, comprises a metering device for at least two components with a metering pump and a remote bulk container for each component, whereby for each component the bulk container is connected via a low pressure transfer pump and low pressure transfer hose to a pump inlet adaptor of the metering pump as well as to an accumulator assembly situated immediately before the inlet of the metering pump. This allows the use of low pressure transfer and low pressure metering systems instead of high pressure metering and high pressure transfer systems and hence lower cost dispensing assemblies.

  • Patent number: 5960809
    Abstract: A fuel equalizing method and system for equalizing the amount of fuel in a plurality of fuel tanks connected to a motor, such as the diesel engine of a truck, is described. The system includes an equalization valve having a first common passage with two fuel inlets connected to two fuel tanks and a fuel outlet connected to the motor. A valve actuator member is mounted in the first common passage for longitudinal sliding movement in response to unequal fuel pressure in the two fuel inlets sensed by two fuel pressure sensing elements, which may be spherical balls, connected to the actuator member. A second common passage is provided in the equalization valve with a return fuel inlet connected to the excess fuel outlet of the motor, and two return fuel outlets connected to the two fuel tanks.

  • Patent number: 5819776
    Abstract: The present invention is an apparatus and method for producing a salt solution suitable for use as a liquid ice and snow remover. The apparatus consists of an internal dual-tank arrangement. The exterior walls of the apparatus form an outer containment tank which holds preferably up to 110% of the volume of the internal dual-tank arrangement. The dual-tank arrangement consists of a hopper tank for holding a soluble salt and a holding tank for holding the produced salt solution. A fluid passageway leads from the hopper tank to the holding tank. Water is fed into the lower portion of the hopper tank. It rises through salt or calcium magnesium acetate pellets located in the hopper tank forming a salt solution. The solution flows through two screened outlets into pipes which lead it to the holding tank. Fresh water is introduced into the salt solution as it exits the hopper tank and enters the holding tank.

  • Patent number: 5636654
    Abstract: A fuel equalization line device couples in fluid communication vehicle tanks and has one or two conduits joined together by a removable coupling device, which provides for fluid communication between the conduits when engaged to equalize fuel levels within the tanks, and enables the fuel equalization line to be separated into two parts to free the tanks from the vehicle frame during a tank removal operation. A pair of shutoff valves enable the fuel to be retained in the tanks when they are removed from the frame.
