A filling head (12) for a fuel tank, particularly of a vehicle, the head including a tubular sleeve (16) of which a first longitudinal end (16a) defines a filling opening and of which a second longitudinal end (16b) is intended to be fixed to one end (14a) of a fuel pipe (14). The head further includes a ring (18) mounted in the sleeve and having a passage orifice for a filling nozzle, wherein the sleeve is made of HDPE and its second end is intended to be fixed by welding to the end of the fuel pipe. An annular seal (36) is mounted between the ring and the sleeve near the second end.

A method of manufacturing a high-pressure tank includes: forming a vessel body including a body portion having a cylindrical shape, a domical portion having a hemispherical shape and provided at an end of the body portion, and a neck portion extending from the domical portion in an axial direction of the domical portion; winding fibers around an outer peripheral surface of the vessel body to form a plurality of fiber layers laminated in a radial direction of the vessel body; and placing, in a mold, the vessel body around which the fibers have been wound, and then injecting a resin onto the neck portion in an axial direction of the vessel body to impregnate the fibers with the resin.

A saddle riding vehicle includes: a fuel tank supported by a body frame; a filler opening provided in an upper surface of the fuel tank; a tank cover covering the upper surface of the fuel tank; and a fuel sump collecting fuel overflowing from the filler opening. The saddle riding vehicle includes a shroud covering a side surface of the fuel tank. The fuel sump is placed around the filler opening and under the tank cover. The fuel sump includes a drain pipe discharging fuel downward. The drain pipe extends between the tank cover and the shroud.

A plastic tank having a connection device for the plastic tank. The connection device includes a connection nipple, composed of a low-emission material, which is to be inserted into or attached to, from the outside, an opening of a tank wall of the plastic tank. A counter-piece is arranged to lay flat against the inside of the tank wall around the opening. The connection nipple is connected by screw connection or clip connection to the counter-piece. A seal is arranged around the opening between the outside of the tank wall and a sealing face of the connection nipple that faces the outside of the tank wall.

The fuel tank adapter for a golf cart is configured for use with a motorized golf cart. The golf cart further comprises a fuel tank and a tank port. The fuel tank adapter for a golf cart is an extension device. The fuel tank adapter for a golf cart extends the tank port by creating a flow path that guides the liquid fuel from an inlet structure located on the exterior of the golf cart into the fuel tank through the tank port. The fuel tank adapter for a golf cart comprises a coupling structure, an extension structure, and the inlet structure. The inlet structure and the coupling structure attach to the extension structure. The coupling structure attaches the extension structure to the tank port of the fuel tank. The inlet structure receives liquid fuel from an external source and transports the received liquid fuel to the extension structure.

A filling device for an operating fluid tank, comprising a tubular outer part and an inner part which is received in the outer part and which is designed to receive an operating fluid nozzle, is characterized in that the inner part comprises a first end wall having an opening and a second end wall having an opening, the end walls being connected to one another via a shell and the shell being provided over the entire length between the end walls with a shell opening whose width corresponds substantially to the corresponding maximum inner width of the shell.

Provided is a method that is for attaching a filler pipe. The method for attaching a filler pipe attaches a filler pipe to the aperture of a fuel tank with an attachment member therebetween, and is characterized by containing: a fitting step for fitting the tubular attachment member to the inside of the aperture of the filler pipe; a contact step for contacting, to the surface at the periphery of the aperture of the fuel tank, a first flange protruding outwards in the radial direction from the outer peripheral surface of the attachment member, and a second flange protruding outwards in the radial direction from the outer peripheral surface of the filler pipe; and a welding step for welding the first flange and second flange to the surface.

A non-pressure valve is provided, and includes a tubular housing having an inlet and an outlet. The tubular housing forms a fluid flow path. The non-pressure valve also includes a sliding sleeve coupled with the outlet, a spring disposed between the sliding sleeve and the tubular housing, and a flow-through mount disposed within the tubular housing adjacent the sliding sleeve. The flow-through mount is coupled with a bulb. The bulb is configured to engage the sliding sleeve and impede the flow of fuel. The non-pressure valve also includes a hose fluidly coupling the non-pressure valve with a remote fuel vent. The flow-through mount may include a plurality of bypass openings positioned in the fluid flow path and configured to divert a portion of the fuel flow through a hose to the remote fuel vent.

The invention is based on the insight that a filling system obtained by combining a Kruse compatible threaded socket and an annular magnet as required for the operation of the Elaflex nozzle, will exhibit air exchange problems related to the difference in the positioning of the respective air intake openings of the Kruse bottle and the Elaflex nozzle. More particularly, the invention is based on the insight that by judiciously providing a chamber in fluid communication with the volume of air or vapor in the tank, filling may be made possible with a Kruse bottle as well as with an Elaflex nozzle.

The present disclosure is directed to a fuel tank fill pipe assembly configured to conduct liquid fuel from a fuel-dispensing nozzle to a fuel tank. The fuel tank fill pipe assembly includes a filler head assembly shaped to receive the fuel-dispensing nozzle and a filler pipe that extends from the filler head assembly toward the fuel tank. In illustrated embodiments, a coupler is included for attaching the filler head assembly to the filler pipe while blocking fuel vapor from escaping the fuel tank fill pipe assembly so that hydrocarbons present in the fuel vapor are not released into the environment.
