  • Patent number: 10857876
    Abstract: Methods and systems are provided for a filler inlet of a fuel fill line of a motorized vehicle. In one example, a filler inlet includes a fuel/air separation chamber extending at an angle relative to an opening of the filler inlet, with the opening adapted to receive a fuel nozzle. Fuel may be guided from the fuel nozzle toward a curved wall of the fuel/air separation chamber by a flow guide, and the fuel may separate from entrained air within the fuel/air separation chamber.

  • Patent number: 9249893
    Abstract: A valve device has a movement element, which is cylindrical at least in sections, and a guide element, which has a guide recess for guiding the movement element and is pressed into a valve housing. The guide element comprises a radially inner ring-like section and a radially outer ring-like section. The guide recess is arranged in the inner ring-like section. On its outer circumference, the outer ring-like section has a number of contact sections which are arranged distributed uniformly over the circumference and by means of which the outer ring-like section is pressed into the valve housing. The inner ring-like section is connected to the outer ring-like section via an identical number of connecting sections, which are arranged distributed uniformly in the circumferential direction, wherein, as viewed in the circumferential direction, the connecting sections are offset radially by an angle of 180 DEG/N in relation to the contact sections.

  • Publication number: 20100116128
    Abstract: A liquid/gas separator device for separating the liquid and gaseous phases of a fluid, the device having first and second vertically-disposed elongate reservoirs. The first reservoir has a first bottom orifice connected to an arrival pipe for the fluid that includes a pressure-lowering device, at least one first top orifice, and a plurality of first intermediate orifices. The first reservoir is connected to a plurality of second reservoirs via a plurality of first transfer pipes, and via at least one second transfer pipe. Each of second reservoirs has a second top orifice connected to a common gas discharge pipe, and a second bottom orifice connected to a common degassed fluid discharge pipe.

  • Publication number: 20090007635
    Abstract: Floating bubble jar gas dryer include a container floating in glycol on top of input gas sample pipe. The gas flow pressure regulates the depth of sinking of the floating container in the drying liquid (glycol for water). Small holes at the bottom of the floating container disperse the gas into the liquid where the diffusion process absorbs the moisture from the gas sample.

  • Patent number: 7141100
    Abstract: A low flow rotary separator includes a housing that defines a separator chamber and a liquid/gas mixture inlet. A shaft driven by a motor includes a plurality of disks in frictional contact with the mixture to drive the liquid outward against an inner wall of the separator and displace gas to a central region about the shaft. The liquid exits through a liquid outlet valve into a high-pressure storage container. The pressure of the liquid is increased to allow flow into the high-pressure storage container by a pump driven by the shaft. A level control valve closes in response to a predetermined pressure differential between liquid in the feed line and liquid within the separator chamber to allow liquid flow through an outlet check valve.

  • Patent number: 6251167
    Abstract: An enclosed tank with a liquid inlet, a liquid outlet, a gas inlet, and a gas outlet. A liquid is forced to flow turbulently through the tank. Simultaneously a scrubbing gas is pumped through the tank. Turbulence induced in the liquid encourages gasses dissolved in the liquid to transfer to the scrubbing gas and thence to exit the gas outlet. Liquid pressure is provided externally to the invention, such as by a water utility or house water pump. The liquid inlet has a nozzle that injects the liquid against baffles in the tank to create turbulence. The liquid level in the tank is stabilized by controlling the scrubbing gas pressure. A lower layer of liquid and an upper layer of scrubbing gas are maintained in the tank as they flow through the tank together. Various liquid level stabilizing means are shown as examples. An electronic feedback system optionally controls the scrubbing gas flow rate according to the contamination level of the liquid.

  • Patent number: 5902382
    Abstract: A degassing system for a hydrocarbon dispenser including a hydrocarbon circulating pump (12). The system includes a degassing assembly (16) having an inlet connected to the outlet of the pump, a degassed hydrocarbon outlet (90), a takeoff outlet (20) for taking off the hydrocarbon/gas mixture, a degassing vessel (24), and a duct (38, 60") for connecting the takeoff outlet to the degassing vessel. The end of the duct which opens out into the degassing vessel has an adjustable effective flow section. The system also includes a valve arrangement (110, 118) for modifying the effective flow section as a function of the gas content of the hydrocarbon.

  • Patent number: 5858070
    Abstract: An apparatus for cleaning hydraulic fluid includes a centrifugal fluid-spinning disk arranged in a housing, of which an upper portion forms a vapor chamber and a lower portion forms a fluid collecting basin. A vacuum pump is connected to the housing through an oil mist separator, such that water vapor is vacuumed away and hydraulic fluid collects in the oil mist separator to then be pumped away. The apparatus further includes preferably a single container that contains both the contaminated hydraulic fluid that is to be cleaned and the cleaned hydraulic fluid. A flexible inlet line and a flexible outlet line with respective hydraulic quick connectors are provided to connect the apparatus and particularly the oil container to a hydraulic system of an aircraft, for example. A high pressure pump connected to the outlet line pumps the cleaned hydraulic fluid into the aircraft hydraulic system and a pressure maintaining valve in the inlet line maintains the system pressure.

  • Patent number: 5728200
    Abstract: A compact deaerator unit used in combination with a boiler feedwater receiver to eliminate corrosion in the feedwater receiver and in other components of a boiler system. The deaerator unit is mounted external to the feedwater receiver for receiving makeup water and return condensate through a spray nozzle, the deaerator unit in one embodiment having a water level overflow supplying the feedwater receiver with deaerated water and a submerged steam supply and temperature control for maintaining water in the deaerator unit at deaeration temperature, with the water level overflow being separated from the spray nozzle by a baffle, the steam supplied to the deaerator unit first passing through the feedwater receiver to continuously purge the receiver of any corrosive gases and maintain a positive steam pressure.
