  • Patent number: 10350521
    Abstract: A filter includes an outlet from a container, the outlet transverse to said inlet and a filter screen within the container that partially surrounds the outlet. In a further embodiment of the foregoing embodiment, the filter screen prevents passage of particles greater in size than 40 to 6000 microns. In a further embodiment of any of the foregoing embodiments, the filter screen provides a pressure drop of less than 0.5 psi. In a further embodiment of any of the foregoing embodiments, the filter screen defines a tortuous path with a bypass there around. In a further embodiment of any of the foregoing embodiments, the filter screen is cylindrical and extends parallel to a length of said container.

  • Publication number: 20120074069
    Abstract: An enhanced system for monitoring clogging of a fluid filter. A differential pressure sensor connects to fluid lines on opposite sides of the filter to measure a pressure difference across the filter. A viscosity-indicating property sensor connects to one of the fluid lines to measure a viscosity-indicating property of the fluid. A filter monitor in communication with the differential pressure sensor and the viscosity-indicating property sensor issues an operator alert when the pressure difference across the filter exceeds a differential pressure set point. The differential pressure set point is a function of the viscosity-indicating property of the fluid in the fluid line. In one embodiment, a fluid flow rate device in communication with the filter monitor indicates a flow rate of the fluid through the filter. The differential pressure set point is additionally a function of the flow rate of fluid through the filter.

  • Publication number: 20090077973
    Abstract: A fuel system for a gas turbine engine comprises a set of starting fuel injectors that operate in a fuel pressurised atomisation mode to atomise fuel that flows therethrough during an ignition and a post-ignition phase and a set of main fuel injectors that operate in an air blast mode to atomise fuel that flows therethrough during the post-ignition phase and a high altitude ready to load phase and an air assist mode to control the pattern of fuel atomisation during a loaded phase.

  • Patent number: 4900233
    Abstract: The presence of a lubricant in compressed gas from a reciprocating compressor including at least one cylinder 76 reciprocally receiving a piston 74 mounted on a rod 60 and connected to a rotary shaft 12 by a rotary to reciprocating motion converting mechanism 44 is avoided by placing a bellows 130 between the cylinder 76 and various components, including a piston rod guide 64, requiring lubrication.
