摘要： A resonant free-piston Stirling engine having a new and improved start-up and control method and system. A displacer linear electrodynamic machine is provided having an armature secured to and movable with the displacer and having a stator supported by the Stirling engine housing in juxtaposition to the armature. A control excitation circuit is provided for electrically exciting the displacer linear electrodynamic machine with electrical excitation signals having substantially the same frequency as the desired frequency of operation of the Stirling engine. The excitation control circuit is designed so that it selectively and controllably causes the displacer electrodynamic machine to function either as a generator load to extract power from the displacer or the control circuit selectively can be operated to cause the displacer electrodynamic machine to operate as an electric drive motor to apply additional input power to the displacer in addition to the thermodynamic power feedback to the displacer whereby the displacer linear electrodynamic machine also is used in the electric drive motor mode as a means for initially starting the resonant free-piston Stirling engine.

摘要： A free piston Stirling engine inertial cancellation system includes a displacer reciprocating in a hermetic vessel enclosing a working space to circulate working gas through a heater, regenerator, and cooler to create a pressure wave in the working space. A power piston, mechanically unconnected to the displacer, is reciprocally driven by the pressure wave to produce a power output stroke in one direction and a working gas compression stroke in the other direction. The displacer and the power piston form substantially a first mass in the working space. A second mass, outside the working space and preferably including an alternator plunger, is mounted in the vessel and is coupled to the first mass momentum exchange relationship. Spring means and tuning means cause the second mass to reciprocate out-of-phase with the displacer and the power piston so that the phase of the moving masses produces inertia phasors which substantially cancel and so that little or no inertia of the reciprocating masses is transmitted through the vessel to the mounting structure of the engine.

摘要： A two-stage harmonic reciprocating Stirling engine has a primary heater and a pair of regenerators with an intermediate heat exchanger disposed in the fluid flow between the two regenerators. High temperature heat above 5000.degree. F. is supplied to the heater head of the engine while lower temperature, otherwise wasted, heat between 500.degree. F. and 1500.degree. is supplied to the intermediate heat exchanger. The lower temperature heat can be from exhaust gases of the primary burner, or can be waste heat from another process for use in a cogeneration installation.

摘要： A phase and stroke control apparatus for the pistons of a Stirling engine includes a ring on the end of each piston rod in which a pair of eccentrics is arranged in series, torque transmitting relationship. The outer eccentric is rotatably mounted in the ring and is rotated by the orbiting ring; the inner eccentric is mounted on an output shaft. The two eccentrics are mounted for rotation together within the ring during normal operation. A device is provided for rotating one eccentric with respect to another to change the effective eccentricity of the pair of eccentrics. A separately controlled phase adjustment is provided to null the phase change introduced by the change in the orientation of the outer eccentric, and also to enable the phase of the pistons to be changed independently of the stroke change.

摘要： A free piston Stirling engine having a hermetically sealed vessel enclosing a working space which can be charged with a working gas under pressure. A displacer, mounted in the working space at the cold end by a spring diaphragm member, to circulate the working gas through a heater, a regenerator, and a cooler to create a pressure wave in the working gas which acts against a power piston to produce output power. The spring diaphragm member provides an effective decrease in the area of the cold end of the displacer which causes the thermodynamic system to provide motive power for maintaining the oscillation of the displacer, supports and centers the displacer in the working space, and functions as a spring to return the displacer towards its center position when it is displaced toward the cold or hot end.

摘要： A Rankine cycle turbine drives an electric generator and a feed pump, all on a single shaft, and all enclosed within a hermetically sealed case. The shaft is vertically oriented with the turbine exhaust directed downward and the shaft is supported on hydrodynamic fluid film bearings using the process fluid as lubricant and coolant. The selection of process fluid, type of turbine, operating speed, system power rating, and cycle state points are uniquely coordinated to achieve high turbine efficiency at the temperature levels imposed by the recovery of waste heat from the more prevalent industrial processes.

摘要： A free-piston Stirling engine usable as a heat pump has a closed vessel filled with helium working gas which is heated at the bottom end and cooled at the top end. The vessel contains a displacer supported for axial reciprocal oscillation on a gas spring post mounted on the vessel. The displacer shuttles the working gas from end to end in the vessel, alternately heating and cooling the gas. The vessel is sealed with a flexible diaphragm which flexes in response to the pressure wave generated in the vessel as the working gas is alternately heated and cooled. When the diaphragm flexes, it displaces hydraulic fluid in a hydraulic chamber and drives a power piston for driving a linear alternator and a gas compressor. A gas spring operating on a second hydraulic cylinder on the other side of the power piston stores part of the energy of the piston stroke and returns it for the return stroke. Controls are provided for balancing and controlling the hydraulic fluid pressure, for starting the Stirling engine, and for modulating its power output.

摘要： A plural fluid magnetic/centrifugal-fluid seal is provided for hermetically sealing the space between a rotated shaft member and a close fitting spaced-apart stationary housing wherein the housing and the shaft are shaped to provide magnetic pole-like close clearance gap regions between their opposed surfaces. A high viscosity ferromagnetic fluid normally is disposed in the magnetic gap region with the rotating shaft member at rest and at low rotational speeds. A permanent magnet or electromagnet is provided which forms a closed magnetic circuit through the magnetic gap region with the high viscosity ferromagnetic fluid. A circumferentially arranged centrifugal seal forming region is radially disposed outward from the magnetic gap region and is located between the rotatable shaft and the stationary housing member. A low viscosity centrifugal sealing fluid is disposed in the centrifugal seal forming region and is centrifugally thrown outwardly during high speed rotation of the rotating shaft member to form a centrifugal hermetic seal between the rotating shaft member and the housing at high rotational speeds of the rotating member.
