A third valve portion is disposed at least partly within the cavity between the first and second valve portions. The second fluid flow path fluidically connects the third valve portion to a trim cavity. A filter media extends from the first valve portion to the second valve portion and divides a third fluid flow path fluidically connecting the first and seconds fluid flow paths.

摘要： A method for determining the optimum inlet geometry of a liquid rocket engine swirl injector includes obtaining a throttleable level phase value, volume flow rate, chamber pressure, liquid propellant density, inlet injector pressure, desired target spray angle and desired target optimum delta pressure value between an inlet and a chamber for a plurality of engine stages. The method calculates the tangential inlet area for each throttleable stage. The method also uses correlation between the tangential inlet areas and delta pressure values to calculate the spring displacement and variable inlet geometry of a liquid rocket engine swirl injector.

摘要： A combustion apparatus 2 has an anti-spreading member 65 disposed below a combustion chamber 10. This anti-spreading member 65 is composed of a generally cylindrical main body 65a, an outer flange 65b and an inner flange 65c, these flanges being formed at and integral with the opposite ends of the main body 65a, respectively.

摘要： The present invention relates generally to devices designed for the combustion of liquid fuels and specifically to an improved apparatus for burning high-viscosity and waste oil. The subject invention utilizes a piston mechanism to transport fuel from its source to the subject burner. The piston mechanism, in conjunction with a pressure-sensitive valve device, also pressurizes the fuel to a predetermined level before releasing said fuel through a nozzle for pressurized dispersion atomization. The piston speed and stroke length can be adjusted in order to regulate fuel flow. After emission from the nozzle, the atomized fuel encounters a single-spark ignition device to induce flame. The atomized fuel and flame produced is enveloped by a unique retention head designed to promote complete fuel combustion and protect the burner chamber from over-heating.
