Relief valve and fuel vapor valve assembly

Номер: US20120024265A1
Автор: Robert Dean Keller
Принадлежит: Eaton Corp

A valve assembly is provided that can perform an overpressure relief function to vent fluid from a first component, such as to vent fuel vapor from a fuel tank, to a second component, such as a carbon canister, without being affected by the vapor pressure in the vent line to the second component. That is, the valve opens to provide pressure relief when needed regardless of the vapor pressure against which it opens. The valve assembly may also include a solenoid that is controllable to allow fluid flow separately from the movement in response to vapor pressure.

Принадлежит: Denso Corp

An ultrasonic element generates an ultrasonic wave and converts an input ultrasonic wave into an electric signal. A transmission circuit outputs a drive signal to the ultrasonic element. A comparator circuit outputs a first detection signal when the electric signal becomes larger than a threshold value and outputs a second detection signal when the electric signal becomes smaller than the threshold value. An arithmetic circuit computes a distance of a propagation path of the ultrasonic wave based on a time difference between an output timing, at which the ultrasonic element outputs of the ultrasonic wave, and a liquid level timing, at which the comparator circuit outputs the first detection signal, and based on a propagation speed of the ultrasonic wave. A storage unit stores a time difference between the first detection signal and the second detection signal. The transmission circuit increases the drive signal, as the time difference decreases.

LIQUID LEVEL GAUGE WITH INTEGRAL ELECTRONIC DISPLAY

Номер: US20190033119A1
Автор: JR. Herbert G., Lease Benjamin Neal, Ross
Принадлежит:

An electronic liquid level gauge assembly includes an electronic display located in a housing connected to a tank. The display has first and second display portions for indicating liquid level condition. A first electronic sensor senses a change in magnetic field of a magnet associated with a liquid level transducer, with magnet rotation being proportional liquid level change. A processor determines a temperature-compensated liquid level condition by correlating the liquid level signal with temperature measurement of the liquid. A temperature-compensated vapor space can also be calculated based on tank information and properties of the liquid. Signals related to the temperature-compensated liquid level and vapor space are sent to the display and wirelessly transmitted to a smart phone or the like for remotely viewing the tank information. The smart phone also includes a special app for sending information, firmware updates, and display configuration data to the electronic gauge assembly. 120-. (canceled)21.

A fuel ejector assembly for a vehicle. A second fluid passage extends into a first fluid passage so that a nozzle opening is arranged inside the first fluid passage facing an outlet flow port such that a first flow of fuel in the first fluid passage flows around the nozzle opening. A flow shape unit is disposed within the first fluid passage in connection to the nozzle opening. 1. A fuel ejector assembly for a vehicle , comprising:a first fluid passage having an inlet flow port and an outlet flow port in fluid communication with each other, enabling a first flow of fuel to flow in the first fluid passage;a second fluid passage connected to the first fluid passage, the second fluid passage having a suction flow port arranged outside the first fluid passage and a nozzle opening, where the suction flow port and the outlet flow port are in fluid communication with each other, wherein the suction flow port is connectable to a fuel tank suction passage enabling a second flow of fuel to flow in the second fluid passage from the fuel tank suction passage via the suction flow port to the outlet flow port;a flow shape unit disposed within the first fluid passage between the inlet flow port and the outlet flow port, where the flow shape unit is configured to raise the flow velocity of the first flow of fuel flowing in a direction from the inlet flow port to the outlet flow port when a first pressure level is applied to the inlet flow port, thereby subjecting the second fluid passage to a second pressure level, which is lower than the first pressure level;wherein the second fluid passage is extending into the first fluid passage so that the nozzle opening is arranged inside the first fluid passage facing the outlet flow port such that the first flow of fuel in the first fluid passage is flowing around the nozzle opening, and wherein the flow shape unit is disposed within the first fluid passage in connection to the nozzle opening.2. A fuel ejector assembly according to claim 1 ...
