internal combustion engine includes an air suction pipe, a throttle valve located in the pipe, and a member upstream of the throttle valve, which is actuatable by air flowing through the suction pipe so as to move a piston valve to dose a quantity of fuel to a fuel injection nozzle. The...
When shutting off rocket engines which are operated with liquid fuel of a type such as, for example, kerosene and liquid oxygen, there is a danger that when the delivery of the liquid fuel stops, hot combustion gases will flow from the combustion chamber back into the injection nozzles so ...
After the first AHDRA Western round at Phoenix where the bike qualified in the middle of the field but got eliminated when an ignition kill malfunctioned shutting the bike off in the burn out, the team moved on to Las Vegas after being invited by the NHRA. No win in Vegas but the bike...
The flow sensor thus provides the monitoring system with continuous acknowledgement of whether a measure aimed at shutting off the nozzle has been successful. If a gas nozzle has not been shut off, due to a structural stipulation or because of a malfunction, or if the operator is continuing ...
A pilot fuel control system 56 delivers a metered flow of fuel via conduit 58 to a pilot fuel nozzle 60 for injection of a combustible mixture in a portion of the combustor 34. A suitable igniter 62 establishes combustion adjacent pilot nozzle 60 and keeps it established. If desired, the ...
the injection water is shut-off when T2equals the desired combustor discharge temperature T3sp. Preferably, in the downhole version, pressure downstream of the combustor is maintained by a check valve 98 (see FIG. 5) above the nozzle 32 so as to prevent well fluids from entering the combustor...
possible to instantly detect flashback, it is still necessary to turn off fuel flow to the nozzle. If the flashback event is not corrected in a very short period of time, or if the flashback causes a flame holding event within the nozzle, the nozzle can be irreparably damaged or ...
The reactor vessel of a nuclear reactor installation which is suspended from the cold leg nozzles in a reactor cavity is provided with a lower thermal insulating barrier spaced from the reactor vessel that has a hemispherical lower section that increases in volume from the center line of the rea...
In the case of past designs of burner systems, medium is jetted or sprayed into a combustion space, using a nozzle head and burnt, after ignition, using oxygen let into the combustion space. For running in the oxygen, air is sucked using a separate blower and forced into the combustion sp...
Injection pump 15 is provided with a capacity control lever 22 by means of which the pump output to nozzle 17 at any given pump speed can be regulated from zero to maximum. Lever 22 is biased toward the zero output or shut-off position by means of a helical spring 28 which, for clarit...
