A mesh filter for a fuel system of a vehicle may include: a frame for maintaining a shape thereof; a mesh member coupled to the frame so as to remove foreign substances contained in fuel, where the mesh member includes a first mesh member and a second mesh member; and an opening unit for opening and closing a fuel path in the first mesh member. In particular, the second mesh member has a mesh size smaller than a mesh size of the first mesh member such that the mesh filter inhibits clogging of the mesh filter with paraffin wax.

A canister that adsorbs and desorbs an evaporated fuel generated in a fuel tank of a vehicle includes an outer case, an inner case, a connecting port, and a sealing member. The inner case has a cylindrical shape. The inner case is fitted into the outer case. The inner case is filled therein with an adsorbent in a granular form. The inner case includes a first end and a second end. The connecting port connects an inside and an outside of the outer case to each other. The sealing member is provided to the second end of the inner case located opposite to the first end leading to the connecting port. The sealing member seals a gap between the outer case and a joining portion of the inner case. The joining portion joins the inner case to the outer case.

A tank system for a construction machine includes a fuel tank having an outer tank wall that closes off a tank volume to the outside, a withdrawal tank volume, which is separated by a partition wall from a main tank volume of the tank volume and has a fuel-exchanging connection to the main tank volume, and a fuel withdrawal arrangement having a main fuel pump and a withdrawal line opening into the withdrawal tank volume for conveying fuel by the main fuel pump via the withdrawal line from the withdrawal tank volume to a fuel-consuming system region. The tank system also includes a fuel feed arrangement having an auxiliary fuel pump for conveying fuel from the main tank volume into the withdrawal tank volume.

Various example embodiments relate to a filtration system. The filtration system includes a filter housing having a first housing end and a second housing end. The filter housing includes a housing cover defining an outlet. The housing cover includes a first guidance element extending from an internal portion of the housing cover axially away from the outlet. A second guidance element extends from the internal portion of the housing cover axially away from the outlet. A filter element has a first filter end and a second filter end. The filter element includes an end cap adjacent the first filter end and defining an end cap opening therethrough. The end cap includes a channel around the end cap opening. Filter media has a first media end and a second media end. The filter media extends axially from the first media end toward the second media end.

A filter arrangement may include a filter housing and a ring filter element arranged in the filter housing. The ring filter element may include an upper end plate, a lower end plate, and a filter material arranged therebetween. An axially projecting pin may be disposed on the lower end plate and may engage into a channel on a filter housing side. The filter arrangement may also include a tubular dome which may engage into an interior of the ring filter element. The tubular dome may have a guide contour. The guide contour may cooperate with a guide element arranged on the ring filter element and may have an axial groove. The guide contour may be configured as at least one of a circular ramp and a chamfered cannula. On the upper end plate, an axial stop may project into the interior of the ring filter element.

A fuel delivery system for controlling an inlet pressure of a prime mover in a transport climate control system is provided. The fuel delivery system includes a fuel tank, a pressure regulator, a pump disposed downstream of the fuel tank, a first filter disposed downstream of the pump, and the prime mover disposed downstream of the first filter. The prime mover is located above the fuel tank in a vertical direction. The pump is configured to provide a first fuel flow through the first filter. The prime mover is configured to accept a first portion of the first fuel flow and is configured to provide a return fuel flow. The pressure regulator is disposed downstream of the first filter. The pressure regulator is configured to accept a second portion of the first fuel flow, and to accept a pressure of the return fuel flow as a reference pressure.

The present disclosure generally relates to a multiple receptacle fuel filling and storage system in a vehicle and/or powertrain, and a method of using the same.

Filter element (1) for filtering a substance, in particular a hydrocarbon, out of a fluid flow, in particular out of a fuel container, with a substrate material (2) on which a sorbing, in particular adsorbing, surface is formed on at least one side, at least in part, wherein the filter element (1) includes multiple mutually-opposite layers of the substrate material (2), wherein the individual layers are arranged so as to be mutually spaced, and wherein the filter element (1) includes at least one spacer (6) that is provided between two layers in each case.

An in-tank fuel pump assembly and mounting system is disclosed which may be configured for mounting inside a fuel tank. The assembly includes a pump housing, pump mounted to the housing, and pressure relief valve. The housing may comprise upper and lower pump housing units coupled together. The upper housing unit is configured for mounting to a tank opening, which in one implementation may be the fuel fill opening. The lower housing unit extends into the tank to approximately the bottom of the tank. A fuel fill fluid pathway is created through the housing for adding fuel to the tank while the pump assembly remains in situ. The upper housing unit may include a removable fuel cap. The pump housing may include an integral vapor trap.
