The flow path of a lubricating oil is modified such that oil is prevented from directly entering the engine unfiltered from an oil reservoir. The adaptor has an integral oil pressure regulator that maintains design oil pressure during conditions of low and high engine speed while directing oil through a filter before entering the engine galleries and passages. The adaptor easily installs and replaces an end plate on a pump housing on the original pump. | 10-10-2013 |
20130312711 | FUEL SUPPLY SYSTEM - A fuel supply system includes a fuel pump having a bottom inlet end configured to pick up fuel and a top discharge end configured to discharge fuel at a pressure higher than that of the inlet end. A housing defines a pressure vessel in fluid communication with the discharge end of the fuel pump. The fuel pump is secured with respect to the housing so that the pressure vessel is laterally adjacent the fuel pump and the pressure vessel and the fuel pump have overlapping heights. Exactly one check valve is positioned between the discharge end of the fuel pump and the pressure vessel, and the check valve is spaced laterally away from the discharge end of the fuel pump at an inlet to the pressure vessel. | 11-28-2013 |
20140116398 | FUEL PUMP MODULE - Provided is a fuel pump module capable of preventing the static electricity from being accumulated on a fuel pump module, and thus preventing firing and explosion, by forming lines from a pump mounting portion on which a fuel pump is mounted to a inlet port of a flange assembly with electrically conductive material and connecting them to a connector formed on the flange assembly with a ground lead line, so that the static electricity generated by the friction caused by the flow of the fuel is discharged to the outside of the fuel pump module, i.e., the chassis of a vehicle. | 05-01-2014 |
20140238359 | Fuel Tank Arrangements for Self-Priming Floating Pumps - An auxiliary fuel tank for portable self-priming floating pumps is configured to float independently of the pump while being retained therewith. The tank features an annular shape having a central opening that is sized to accommodate receipt of the pump, whereby the tank fits around the pump so as to move therewith over the body of water in which the pump is deployed. | 08-28-2014 |
20140290627 | FUEL SUPPLY DEVICE AND SADDLE TYPE VEHICLE - A fuel supply device is provided with a fuel pump and a filter. The fuel pump supplies fuel from a fuel tank to an engine. The filter is disposed upstream from the fuel pump in a fuel supply channel. The filter includes a first filter portion and a second filter portion. The first filter portion and the second filter portion filter the fuel. The second filter portion is disposed above the first filter portion when the filter is disposed inside the fuel tank. A density of gaps in the second filter portion is larger than a density of gaps in the first filter portion. | 10-02-2014 |
20140373813 | VENTING A FUEL TANK BY MEANS OF A FUEL SUPPLY PATH AND AN AIR SUPPLY PATH OF AN INTERNAL COMBUSTION ENGINE - The invention relates to a system ( | 12-25-2014 |
20150059707 | FUEL PUMP MODULE - A fuel pump module for a fuel tank having a plurality of fuel tank rooms includes a jet pump with a jet part, a suction part, and a swirling flow formation member that has relatively-small openings that are symmetrically disposed on a center axis of the jet part on one side of the member close to the suction part. The fuel passing through the openings are induced into a swirling flow that is injected into the suction part for transporting the fuel from one tank to an other tank. As a result, fuel may be efficiently transported from the one tank to the other tank without having a fuel pump in the one tank. | 03-05-2015 |
20150059708 | FUEL PUMP MODULE - A noise from a fuel pump module is reduced by housing a port injection (PI) fuel pump in a pump case of a fuel tank, in a structure in which the PI fuel pump is held with a bracket that is provided at a position between the PI fuel pump and a PI suction filter. The PI fuel pump and the bracket that engages with the pump case are interposed by an elastic member that abuts a base part of the bracket. In operation, when the PI fuel pump transmits its vibration to the pump case through the elastic member and the bracket, the elastic member dampens and reduces the vibration transmitted to the bracket, thereby reducing the noise by a reduction of transmitted vibration through the pump case to a subtank and the fuel tank. | 03-05-2015 |
20150059709 | FUEL PUMP MODULE - A fuel pump module for a fuel tank providing improved rigidity includes a first module and a second module. The first module includes a first tank having a first tank room, a direct injection (DI) fuel pump and filter, a port injection (PI) fuel pump and filter, a subtank, and a first flange supporting the filter, the pump, and the like. The second module includes a second tank having a second tank room where fuel is stored separately from the first tank room, a PI filter, a second jet pump, a second flange supporting the filter, the pump, and the like. As a result, a size of two flanges supporting two fuel pumps and two filters is reduced, thereby, reducing a size of two openings of the fuel tank. | 03-05-2015 |
20150101576 | SADDLE-RIDE TYPE VEHICLE - A saddle-ride type vehicle includes a frame, an engine, a starter motor, a predetermined component, and a coupling member. The engine is supported by the frame. The starter motor is attached to the engine. The predetermined component is disposed adjacent to the starter motor. The coupling member couples the predetermined component to the starter motor. | 04-16-2015 |
20160025055 | CYLINDER HEAD BLANK, CYLINDER HEAD AND HIGH-PRESSURE PUMP FOR FUEL INJECTION SYSTEMS - The invention relates to a cylinder head blank ( | 01-28-2016 |
20160052612 | APPARATUS AND METHOD FOR TRANSFERRING INFLAMMABLE MATERIAL ON MARINE STRUCTURE - A system for supplying fuel to an engine of a ship. The system includes a high pressure pump pressurizing a liquefied natural gas (LNG) and supplying the pressurized LNG to the engine, a hydraulic motor driving the high pressure pump and a chamber carrying the high pressure pump and the hydraulic motor. The chamber is substantially free of electric sparks. | 02-25-2016 |
