A dryer cartridge for removal of water from a liquid is provided with a cartridge body having a receiving chamber and a cartridge body wall delimiting the receiving chamber at least in sections thereof, wherein the cartridge body wall allows the liquid to flow through. A drying agent is arranged in the receiving chamber. A connection head is provided that can fasten the dryer cartridge in an opening of a housing wall of a device for receiving the liquid. The connection head has a connection opening and the connection opening connects in fluid communication the receiving chamber to an environment of the cartridge body. A drying system is provided with a device for receiving the liquid and with the dryer cartridge that can be fastened to an opening of a housing wall of a device for receiving the liquid.

A fuel tank system constructed in accordance to one example of the present disclosure includes a fuel tank and an evaporative emissions control system. The evaporative emissions control system is configured to recapture and recycle emitted fuel vapor. The evaporative emissions control system includes a liquid trap, a first device, a second device, a control module and a G-sensor. The first device is configured to selectively open and close a first vent. The second device is configured to selectively open and close a second vent. The control module regulates operation of the first and second devices to provide over-pressure and vacuum relief for the fuel tank. The G-sensor provides a signal to the control module based on a measured acceleration.

An embodiment fluid recovery structure includes a body having an interior cavity, ports integrally joined to first walls of the body and having port walls that extend away from the body, with each of the ports having a port opening that is contiguous with the interior cavity, and a drain structure integrally joined to a second wall of the body and having a drain hole that extends from the interior cavity through the drain structure.

A fuel tank system is provided. In the main tank of the system, the end of a communication pipe is located above the end of a fuel introduction pipe inserted into the main tank. The end of a first pressure relief pipe at which a first cut-off valve is provided is located above the end of the communication pipe. In the auxiliary tank, the end of the communication pipe is located above the end of the fuel introduction pipe inserted into the auxiliary tank. In the auxiliary tank, the end of a second pressure relief pipe at which a second cut-off valve is provided is located above an end of a scavenging pipe.

A closed tank system includes: a fuel tank; a canister adapted to adsorb evaporative fuel generated in the fuel tank; a fill-up limiting valve provided inside the fuel tank so as to be communicated with the evaporative fuel discharge passage and adapted to operate to close the evaporative fuel discharge passage when a fuel level reaches a predetermined full tank liquid level; a shut-off valve adapted to operate to open or close the evaporative fuel discharge passage; a fuel remaining amount sensor adapted to detect a remaining amount of fuel; and a hardware processor that causes a control section to carry out control for allowing the shut-off valve to be opened or closed. The hardware processor causes the control section to inhibit the control for allowing the shut-off valve to be opened when an engine is in operation and the detected remaining amount of fuel exceeds a predetermined threshold.

A fuel vapor recovery apparatus includes an adsorbent canister capable of capturing fuel vapor produced in a fuel tank, a purge passage connecting the adsorbent canister to an intake passage of an engine, and a purge pump for delivering fuel vapor from the adsorbent canister to the intake passage via the purge passage. The purge pump has a pump part and a motor part configured to drive the pump part. The fuel vapor recovery apparatus further includes a prevention mechanism for preventing liquid fuel liquefied from the fuel vapor in the purge passage from entering the motor part through the pump part.

An active drain liquid trap configured for use with a fuel tank system and constructed in accordance to one example of the present disclosure includes a trap body, a float and a pilot. The trap body defines a first inlet, a second inlet and an outlet. The first inlet is fluidly connected to a fuel pump. The second inlet is fluidly connected to a vapor line. The float is rotatably mounted about a float pivot. The pilot moves between an open and closed position. Rotation of the float causes the pilot to be urged into an open position and fluid to be drained from the trap body through the outlet.

An evaporative emissions control system configured for use with a vehicle fuel tank includes a purge canister, an accelerometer, first and second vent tubes that terminate at first and second vent openings, a first vent valve, a second vent valve, a vent shut-off assembly and a control module. The accelerometer senses acceleration in an x, y and z axis. The first vent valve is fluidly coupled to the first vent tube. The second vent valve is fluidly coupled to the second vent tube. The vent shutoff assembly selectively opens and closes the first and second valves. The control module estimates a location of liquid fuel based on the sensed acceleration from the accelerometer and determines which vent opening is one of submerged and about to be submerged based on the estimated location of the liquid fuel. The control module closes the vent valve associated with the determined vent opening.

An embodiment fluid recovery structure includes a body having an interior cavity, ports integrally joined to first walls of the body and having port walls that extend away from the body, with each of the ports having a port opening that is contiguous with the interior cavity, and a drain structure integrally joined to a second wall of the body and having a drain hole that extends from the interior cavity through the drain structure.

A liquid fuel catcher has a case which defines a plurality of chambers formed as depressions in a passage so that a liquid fuel is accumulated. The case has a communicating portion which communicates the chambers in series at upper portions thereof. The case has openings at each bottom portions of the chambers. The case has a return passage which returns the liquid fuel accumulated in the chambers to a fuel tank. The liquid fuel catcher has a return valve. The return valve closes the return passage, when the liquid fuel level in the fuel tank exceeds a predetermined level. The return valve opens the return passage, when the liquid fuel level in the fuel tank is less than a predetermined level. The fuel returns to the fuel tank from the chambers through the return valve.
