220860300 | With anti-siphon means | 11 |
20090134159 | ANTI SIPHON TANK INLET - The present invention provides a fluid tank inlet assembly having an inlet pipe extending from a mounting structure located at the proximal end of the pipe. A float valve assembly is disposed beyond the distal end of the inlet pipe and includes a float member. An obstruction is located within a housing between the inlet pipe and the float member. The obstruction blocks the line of sight or direct path between the inlet pipe and the float member, but a flow path remains and is defined between the obstruction and the housing wall to allow fluid to flow around the obstruction to the float valve assembly. | 05-28-2009 |
20100206873 | ANTI-THEFT DEVICE FOR MOTOR VEHICLE FUEL TANK - An anti-siphoning device for vehicle fuel tanks includes a barrier in the form of a honeycomb with hexagonal openings located between the fuel tank inlet and the tank itself. The device includes a retractable extension to accommodate a fuel refilling nozzle and openings to allow air in and out of the tank, which makes the refilling process easier. | 08-19-2010 |
20100258560 | Anti Siphon Ball - An anti siphon device constructed of polyethylene balls and placed within a fuel filling neck, above the fuel tank. The anti-siphon device is comprised of an outer perforated ball with an inner axis mounted ball on the interior. The device will allow the free flow of fuel while blocking siphon mechanisms to pass through and reaching the fuel stored below. The device is inexpensive to manufacture and install and does not negatively affect the vehicle operation or fuel refilling capacities. | 10-14-2010 |
20100264138 | Fuel Filler Tube Anti-Siphon Device - A fuel filler tube having a plurality of spaced ribs disposed within walls of the tube, the ribs being staggered along a length of the tube. The plurality of ribs span is disposed across opposing wall portions of the tube. | 10-21-2010 |
20100270300 | STRUCTURE FOR FUEL FILLING SECTION OF FUEL TANK - A structure for a fuel filling section of a fuel tank is obtained, in which valve opening pressure of a negative pressure valve, that opens a fuel filling port when a fuel tank interior is negative pressure, can be set independently of a valve opening pressure of an opening/closing valve that opens the fuel filling port due to insertion of a fuel filling gun. A positive pressure valve ( | 10-28-2010 |
20110031245 | Anti Siphon Tank Inlet - This invention relates to inlet devices that include, for example, a tubular inlet body having a central bore defined by a tubular wall and having an axis. The tubular wall defines an open proximal end for receiving fuel. A plurality of apertures are provided through the tubular wall for egress of fuel. The distal end of the tubular body is blocked by a baffle defining a baffle surface facing into the bore of the tubular body, wherein at least a portion of the baffle surface is inclined at an acute angle relative to the axis to deflect fuel towards apertures in the tubular wall; and wherein the baffle surface is at least substantially free from apertures. | 02-10-2011 |
20120125927 | Integrated anti-siphon fuel filler assembly and method of manufacturing the same - One embodiment of an integrated anti-siphon fuel filler assembly for placement in an opening of a fuel tank includes tube means including a first end region adapted to be secured directly to the fuel tank for allowing fuel to flow therethrough into an opening of the tank, and restriction means positioned in the tube and defining apertures for the flow of fuel there through. | 05-24-2012 |
20120181275 | Anti-siphoning device for fuel tanks - An anti-siphoning device for use in the tubular fuel filling neck of a vehicle such as a large truck includes a tubular body, which is mounted in the filling neck, resilient fingers on the body for resisting removal of the body from the neck, a plate in the body with a central opening for receiving a fuel dispensing nozzle, vent openings in the plate around the central opening for discharging gases from the fuel tank during a filling operation, a tube extending downwardly from the central opening, and a cage on the bottom end of the tube for preventing insertion of a siphoning tube into the tank. | 07-19-2012 |
20130213964 | SIPHONING-OFF GUARD - A siphoning-off guard for a motor vehicle tank system that includes a filler pipe head, a tube and a motor vehicle tank, the motor vehicle tank system contains components which form an end region, the siphoning-off guard being fastened to the end region on the outside surface of the component. | 08-22-2013 |
20140034639 | ANTI-SIPHONING FUEL DEVICE, SYSTEM, AND METHOD - An anti-siphoning fuel system that includes a fuel inlet, a fuel tank, at least one fill tube or hose connecting the fuel inlet to the fuel tank such that fuel may flow from the fuel inlet to the fuel tank, and an anti-siphoning element or device coupled to the fill tube or hose that may be installed in existing boats or cars and obstructs a siphoning hose inserted into the fill tube or hose from entering the fuel tank. | 02-06-2014 |
20140263312 | FUEL THEFT PREVENTION DEVICE FOR AUTOMOBILE - A fuel theft prevention device for an automobile, which is capable of preventing extraction of fuel from a fuel tank using a fuel extraction hose. In the fuel theft prevention device, a hose intrusion prevention member is attached inside a filler pipe, and the hose intrusion prevention member has an attaching section, an intrusion preventing section and a connecting section. The intrusion preventing section has a plurality of end parts, each being brought into contact with or close to an interior surface of the filler pipe, and a plurality of holding parts adapted to hold the end parts and connect the end parts and an end of the connecting section to each other, and the intrusion preventing section is attached in a prescribed position inside the filler pipe. | 09-18-2014 |
