An actuator and valve assembly for a hydraulically-actuated electronically-controlled unit injector is disclosed which comprises an electrically-energizable actuator including a movable member and a poppet valve connected to the movable member. The poppet valve has a first seat and a second seat and is movable along an axis between first, second and third positions. The assembly further comprises a device for biasing the poppet valve towards its first position and a device for accommodating misalignment of the first and second seats relative to the axis. The poppet valve is advantageous because it has high fluid flow control capability in a one-piece single-stage configuration.

The invention is concerned with an improvement in a modular gas turbine engine assembly comprising a tubular case, a gasifier module detachably attachable with a first end thereof adjacent a first end of said case and a power output module detachably attachable with a first end thereof adjacent a second end of said case, said case and said modules defining a partially walled off combustion-ducting section within said engine. The improvement comprises a plurality of individually replaceable insulation packs which provide heat insulation between the combustion-ducting section walls and each of said case, said gasifier module and said power output module. In another sense the invention comprises an improved individually replaceable insulating pack comprising a high temperature resistant metallic sheet having a porous insulation blanket and including a fine mesh of wire covering the surface of the blanket which is not adjacent to the sheet and holding the blanket against the sheet.

The invention is concerned with an improvement in a movable vane assembly of the type used in a gas turbine engine or compressor for interaction with a gas stream. Most particularly, the invention is an improved temperature independent means for indicating the rotational position of a plurality of radially aligned vanes circumferentially arranged in an annular passage formed by a housing, said vanes being supported for rotation about their radial axes to vary the effective cross-sectional area of said annular passage, a plurality of rotatable gear means connected for rotation with said plurality of aligned vanes, a ring gear having teeth means adapted for simultaneous engagement with teeth means of said plurality of rotatable gear means such that rotation of said ring gear causes rotation of said plurality of vanes, actuating means including first and second link means connected at first and second diametrically opposed points on said ring gear, and motor means for simultaneously actuating said first and second link means to rotate said ring gear. The improved temperature independent means of the present invention comprises a potentiometer having a body and a stem rotatable with respect to the body with the resistance of the potentiometer being a function of the relative rotation between the body and the stem. Means are provided mounting the body to rotate a first distance in a first direction responsive to a first change in size of the first link means.

The invention is concerned with an improved individually replaceable insulation pack comprising a high temperature resistant thin flexible metallic sheet having a porous insulation blanket formed of interlaced ceramic fibers held against a side thereof and including a fine mesh of wire covering the surface of the blanket which is not adjacent to the sheet and holding the blanket against the sheet. The blanket does not contain a binder and is not bonded to the sheet.

A cooling system for a gas turbine engine having a gasifier turbine and a power turbine each interconnected by a turbine casing utilizes compressed cooling air communicated to axial cavities in the ends of the respective turbine shafts. This compressed air is directed outwardly between a flange integrally formed with the turbine shaft and the turbine wheel for communication to the turbine blades. In the gasifier turbine the cooling air passes through longitudinal passages formed in each blade, while in the power turbine the cooling air is discharged adjacent the blade root. Wheel flanges affixed on either side of the turbine wheel serve to retain the blades axially on the wheel. Compressed cooling air is also communicated to the nozzle vanes of the gasifier turbine wherein internal passages communicate the air into the main gas stream. Certain nozzle vanes are equipped with passage means to communicate air to an annular chamber surrounding the gasifier turbine.
