摘要： A self-pumping fuel injector includes a pump and a motor for, in-part, delivering fuel to a combustor at higher fuel pressures during start-up and ramping-up conditions. Each pump may include a stationary flow interuptor that intermittently and variably supplies fuel to a rotating spindle that, in-turn, expels the fuel into a nozzle of the injector for improve fuel spray distributions.

摘要： The present invention materially enhances the quality of the environment and mankind by contributing to the restoration or maintenance of the basic life-sustaining natural elements. The present invention reduces the amount of carbon monoxide introduced to the atmosphere of a combustion system. This is achieved by furnishing a systems approach to optimize the amount of oxygen to be chemically combined with fuel upon ignition of both allowing the correct amount of carbon to combine with the correct amount of oxygen thus fully release the thermal energy stored therein. By so furnishing the level of oxygen with carbon of the fuel, more carbon dioxide is produced thus proportionally reduces the amount of carbon monoxide released to the atmosphere. The present invention provides a heating system that surpasses the net and gross efficiency performance of a natural gas burner.

摘要： A fuel delivery system for a gas turbine engine that employs a technique for purging fuel delivery tubes in an effective manner. The fuel delivery system includes at least one multifunction valve that has a flow through position and a bi-directional purge position. The fuel delivery system also includes at least one flow divider that is positioned downstream from the multifunction valve and divides the flow of fuel from the valve into a number of the fuel delivery tubes, where a separate fuel delivery tube is provided for each combustor in the engine. The flow divider includes a pump element for all of the fuel delivery tubes that can operate in a forward and a reverse direction. Purge water provided downstream from the flow divider for each of the fuel delivery tubes can be pumped by the flow divider when the multifunction valve is in the purge position.

摘要： The present disclosure is directed to a mobile machine, such as hydronic surface heater designed to be transported to a potentially remote worksite and operated for an extended period of time. The machine has a fueled component, such as a burner, fueled by a fuel supply system having at least two fuel tanks that are operably connected to one another by a connection line having an electronically controlled valve therein. The valve is coupled to the machine's electrical system, such as being coupled to the output of the machine's main breaker, so as to be opened whenever the machine is operating but to be otherwise closed. The fuel supply system thus has, in effect, a single tank when the machine is running and multiple separated tanks when the machine is not running. Fuel spill risks therefore are mitigated without having to sacrifice operating time and without significantly complicating the machine's fuel supply systems or its controls.

摘要： A fuel supply system for a general purpose internal combustion engine is equipped with a sub-fuel tank that retains gasoline fuel supplied from a main fuel tank and houses the high-pressure pump in its interior. In other words, the pump is immersed in the gasoline fuel retained in the tank, so that if an air pocket should occur in the fuel supply pipe between the main fuel tank and pump, the air will be discharged from the sub-fuel tank to the exterior through a fuel return pipe etc., thereby ensuring that the pump does not suck in air. Since fuel injectors can therefore inject gasoline fuel immediately, starting performance is enhanced.

摘要： In an apparatus for supplying a fuel to a vehicular combustion heater which supplies the fuel from a fuel tank via a fuel pump to the heater which is mounted on an electric vehicle, discharging into atmosphere of fuel vapor from the fuel tank is restricted to the best extent possible. For that purpose, prevention is made of that discharging from the combustion heater of the fuel vapor which is likely to occur when the set pressure for opening a positive pressure valve in a two-way valve for the fuel tank is set high. Interposed in series between the fuel pump and the combustion heater is a one-way valve which opens when the internal pressure in the fuel supply passage has risen to a predetermined set pressure which is higher than the set pressure for opening the positive pressure valve, and a solenoid valve which is opened when the combustion heater is in operation. The solenoid valve is arranged such that the leak pressure to cause the fuel to leak through the solenoid valve at the time when the solenoid valve is kept closed is higher than the set pressure for opening the one-way valve.
