摘要： A drive mechanism for delivery of infusion medium a coil capable of being electrically activated to provide an electromagnetic field. The coil surrounds a piston channel extending in an axial direction. An armature is located adjacent the coil, on one side of the axial channel. The armature is moveable toward a forward position, in response to the electromagnetic field produced by activation of the coil. A piston is located within the piston channel and is moveable axially within the channel to a forward position, in response to movement of the armature to its forward position. The armature and piston are moved toward a retracted position, when the coil is not energized. The armature may be configured with a reduced diameter by including a coil cup for supporting the coil including a shelf portion defining at least a portion of a pole surface of the coil cup.

摘要： A modulating valve is described for controlling the flow of a working fluid through a flow orifice. The valve includes a encapsulated armature having a permanent magnet and a pair of soft iron pole pieces within its interior. The armature is axially movable by the passage of current through one or a dual pair of solenoid coils surrounding the armature. A thin webbed sealing disk is stretched over the end of an armature housing extension and acts to close or modulate flow of working fluid by varying the axial clearance between the disk and a stationary annular seat of the flow orifice. The armature is supported on flexure guide springs that allow armature axial motion when axial magnetic forces are applied to the armature. These axial forces are provided by the interaction of the solenoid coil(s) and the field of the permanent magnet. A magnetic field gradient produced by the permanent magnet allows the coil to apply a force to the armature in either the valve opening or valve closing direction, depending on the coil current polarity. An armature velocity signal is used in a closed loop servo control of valve position to suppress valve oscillation and over shoot when a change in valve position is commanded.

摘要： A rotary machine includes a helical flow compressor/turbine and a permanent magnet motor/generator including a housing with a stator positioned therein. A shaft is rotatably supported within the housing. A permanent magnet rotor is mounted on a shaft and operatively associated with the stator. An impeller is mounted on the shaft and includes an impeller disk with a plurality of impeller blades extending therefrom. The housing includes a generally horseshoe-shaped fluid flow stator channel with an inlet at a first end and an outlet at a second end. The fluid in the generally horseshoe-shaped fluid flow stator channel proceeds from the inlet to the outlet while following a generally helical flow path with multiple passes through the impeller blades. The impeller disk has a plurality of axially-oriented vent holes formed therethrough to minimize a pressure differential across the impeller, thereby minimizing thrust loads applied to the impeller.

摘要： A liquid fuel pressurization and control system is disclosed which utilizes either a helical flow pump, or a helical flow pump followed by a gear pump, to pressurize liquid fuel to precisely the pressure level required by a turbogenerator's combustor injectors. This eliminates the need to overpressurize the fuel then regulate the fuel pressure down using a flow control valve or a pressure control valve. The shaft torque and shaft speed of the pump are controlled by the turbogenerator's power controller so as to assure that the turbogenerator's speed is precisely controlled (e.g. within ten (10) rpm out of one hundred thousand (100,000) rpm), and that its turbine exhaust temperature is precisely controlled (e.g. within two (2) degrees Fahrenheit out of twelve hundred (1200) degrees Fahrenheit) over the full range of turbogenerator electrical output power. The system also provides cool, high pressure air to assist atomization of the liquid fuel in the injectors utilizing a variable speed helical flow compressor. The system also adjusts the relative fuel flow through the multiple fuel injectors to aid flame stability at low turbogenerator speeds and low output power levels.

摘要： A compound shaft for a three journal bearing turbomachine which includes a first stiff shaft supported by two journal bearings, a second stiff shaft supported by one journal bearing and by one bi-directional thrust bearing, and a flexible disk shaft that operably connects the first and second stiff shafts. The flexible disk shaft utilizes a flexible disk to function as a low hysterisis joint in parallel with a non-linear trunion clock spring such that the flexible disk shaft transfers overturning support from the first stiff shaft to the second stiff shaft and transfers thrust bearing support from the second stiff shaft to the first stiff shaft. The flexible disk shaft allows the compound shaft to tolerate extremely large misalignments of the three journal bearings from a straight line axis. The dynamic characteristics of the compound shaft (especially the axial location of the flexible disk of the flexible disk shaft) are utilized to tune the frequencies of the turbomachine's rigid body and flexural criticals. All rigid body critical frequencies can be set below twenty percent of the machine's maximum operating speed and all flexural critical frequencies can be set more than thirty five percent above the turbomachine's maximum operating speed.
