Provided is a roll over fuel-vapor valve is provided including a housing defining a valve having a valve inlet port extending through a wall of the housing and a valve outlet port and a float member disposed between the inlet port and the outlet port and being displaceable between an open position and a closed position the hosing further comprising a fluid flow channel extending along a top portion thereof and having a first end and a second end, wherein the outlet port extending into the channel such that in the open position fluid flow is facilitated between the valve inlet port and the channel.

The invention relates to a vent valve (1) for controlling the internal tank pressure of a fuel tank, having at least one valve housing (2) having at least one first connection (3) to the fuel tank and at least one second connection (4), which can be connected to a vent line leading to a fuel vapor filter. The vent valve (1) comprises at least one valve element, which is held in a valve seat (8) in a position in which it closes the first connection (3) by the force of gravity and/or by spring loading and, after a given pressure threshold is exceeded, is raised from the valve seat (8) and, when a given pressure threshold is undershot, returns to the initial position. The valve element and/or the valve element guide has/have at least one relief opening (10), which forms a bypass for a gap flow which arises, for example, during a return movement of the valve element.

A method of monitoring a vehicle includes monitoring a precollision fuel level, detecting a collision event, and detecting a vehicle orientation based at least on the precollision fuel level and a postcollision fuel level. The method can be executed by a controller having a processor and a memory storing processor-executable instructions where the processor is programmed to monitor the precollision fuel level, detect the collision event, and detect the vehicle orientation based on at least a precollision fuel level and a postcollision fuel level.

The invention relates to a fuel tank for a motor vehicle, comprising a tank body made from thermoplastic with a tank wall which defines a tank volume which can be closed in a substantially fluid-tight manner, with at least one filler opening and with one or more functional insert components which are arranged within the tank volume, at least one blind opening with a single use closure being provided in the tank wall.

A valve, a multi-functional combination valve and a CFLVV valve simultaneously achieve the functions of a refueling limit valve and a rolling-over valve in a fuel tank. The valve body includes a valve core accommodating cavity, and first and second inflow passages, a first discharge port, and a second discharge port communicating therewith are provided. The valve core accommodating cavity includes two independent vertical-sliding first valve core assemblies and second valve core assemblies for opening or closing the first discharge port and the second discharge port. The pressure maintaining part is connected to the second discharge port and contains a certain opening pressure. After the first valve core assembly closes the first discharge port, and a certain pressure value has to be reached in the valve core accommodating cavity, the pressure maintaining part will open the second discharge port, and the fluid will flow out of the second discharge port.

A vent apparatus is described for providing filtered air intake and rollover protection for a fuel tank. The apparatus may include a housing configured to be coupled with the fuel tank, the housing including at least one air intake port and at least one air exhaust port. The apparatus may include an air intake filter disposed within the housing and configured to receive and filter air from the at least one air intake port. The apparatus may include a rollover protection valve disposed adjacent to the housing and configured to be located inside the fuel tank when the housing is coupled with the fuel tank, the rollover protection valve coupled with the at least one air exhaust port. The rollover protection valve may include a chamber and a plug configured to impede the flow of fuel from the fuel tank into the at least one air exhaust port.

A self-propelled agricultural application machine includes a chassis which carries a storage tank for the material to be applied. The chassis has a central longitudinal beam from which at least a pair of wheels is suspended. A transversely-extending boom assembly is suspended from the longitudinal beam. An engine is located to one side of the longitudinal beam and has an output drive shaft connected through the longitudinal beam to hydraulic pumps. The narrow chassis allows steerable wheels to be positioned at tolerable track widths while permitting a large steering angle and thus small turning radii.

A method of monitoring a vehicle includes monitoring a precollision fuel level, detecting a collision event, and detecting a vehicle orientation based at least on the precollision fuel level and a postcollision fuel level. The method can be executed by a controller having a processor and a memory storing processor-executable instructions where the processor is programmed to monitor the precollision fuel level, detect the collision event, and detect the vehicle orientation based on at least a precollision fuel level and a postcollision fuel level.

A fuel tank assembly having a fuel tank and a first valve assembly in fluid communication with the fuel tank configured to selectively allow air to pass through an outlet vent when the vehicle is in an operational orientation, and to restrict fuel flow from out of the gas tank if the vehicle is not in an operational orientation. The fuel tank assembly also has a second valve assembly in fluid communication with the first valve assembly configured to regulate pressure within the fuel tank by permitting air to enter the fuel tank when internal pressure of the fuel tank falls below a first threshold, and permitting air to exit the fuel tank when internal pressure exceeds a second threshold. The valve assemblies are connected in-line such that air entering or exiting the fuel tank via the outlet vent passes through both the first and second valve assemblies.
