Abstract: An opposed piston gamma type Stirling machine has its displacer driven by a linear electromagnetic transducer that is drivingly linked to the displacer and is located on the opposite side of the power piston's axis of reciprocation from the displacer preferably in the bounce space. The linear transducer is controlled by an electronic control as a function of sensed inputs of Stirling machine operating parameters. In addition to allowing improvements in stability and efficiency, such a Stirling machine operated as a cooler/heat pump can also be controlled so that its displacer can be driven at (1) a phase angle that pumps heat in one direction through the machine or (2) at another phase angle that pumps heat in the opposite direction through the machine and allows selectively switching between the heat pumping directions.

Abstract: A bearing support system for a piston and its connecting rod in which the bearing system supports the combined piston and connecting rod by only two bearings, a gas bearing at the piston and a radially acting spring bearing at its connecting rod. A non-compliant connecting rod is fixed to an end of a piston which has a clearance seal length in the range of 0.3 times the diameter of the piston and 1.5 times the diameter of the piston. The distance from the gas bearing to the effective point of connection of the radially acting spring bearing to the connecting rod is greater than the seal length of the piston. The piston and connecting rod unit is not supported by additional bearings that introduce additional alignment problems.

Abstract: A beta-type free-piston Stirling cycle engine or cooler is drivingly coupled to a linear alternator or linear motor and has an improved balancing system to minimize vibration without the need for a separate vibration balancing unit. The stator of the linear motor or alternator is mounted to the interior of the casing through an interposed spring to provide an oscillating system permitting the stator to reciprocate and flex the spring during operation of the Stirling machine and coupled transducer. The natural frequency of oscillation, ωs, of the stator is maintained essentially equal to ω p ⁢ 1 - α p k p and the natural frequency of oscillation of the piston, ωp, is maintained essentially equal to the operating frequency, ωo of the coupled Stirling machine and alternator or motor. For applications in which variations of the average temperature and/or the average pressure of the working gas cause more than insubstantial variations of the piston resonant frequency ωp, various alternative means for compensating for those changes in order to maintain vibration balancing are also disclosed.

Abstract: The invention provides a compact and inexpensive cooling device with high heat transfer efficiency and with easy maintenance. The cooling device includes a condenser (10), an evaporator (20), and a pair of refrigerant flow passages between them. In each of the condenser (10) and the evaporator (20), through holes (11a, 21a) are formed in parallel with each other. The condenser (10) is formed in a cylindrical shape and installed around the cooling head of the refrigerator by a clamp (14). The evaporator (20) is installed the outside. The refrigerant is liquefied in the condenser (10) by releasing its heat, flows down into the evaporator (20) through the flow passage and is vaporized in the evaporator (20) by absorbing heat from the outside. The vaporized refrigerator flows up and returns into the condenser (10).

Abstract: A heat pumping machine, such as used for home heating and cooling, has a free piston Stirling engine driving a vapor compression heat pump. The engine is mechanically linked to the compressor inside a common hermetically sealed enclosure. A fluid conducting passage connects the refrigerant flow path in communication with a working gas space in the Stirling engine. Although carbon dioxide may be used in both as the refrigerant and the engine working gas, preferably both helium and carbon dioxide are used and separated by a phase separator so that helium rich gas is directed into the Stirling engine and carbon dioxide rich fluid is directed through the heat pump.

Abstract: 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.

Abstract: A bearing support system for a piston and its connecting rod in which the bearing system supports the combined piston and connecting rod by only two bearings, a gas bearing at the power piston (or displacer) and a radially acting spring bearing at its connecting rod. The spacing between them meets prescribed relationships and preferably exceeds a calculated value based upon chosen engineering parameters. A non-compliant connecting rod is fixed to an end of a piston which has a clearance seal length in the range of 0.3 times the diameter of the piston and 1.5 times the diameter of the piston. The distance from the gas bearing to the effective point of connection of the radially acting spring bearing to the connecting rod is greater than the seal length of the piston. The allowable off-center distance A for the radial displacement of the fixed connection of the radially acting spring bearing to the connecting rod is considerably greater than the diametrical clearance gap g which illustrates the reduction in the required precision for adjusting the position of the radially acting spring bearing. The piston and connecting rod unit is not supported by additional bearings that introduce additional alignment problems.

Abstract: An apparatus for determining position of a free piston used in such as hydraulic compressor, which has no mechanical connection with crank shaft, and an apparatus for controlling reciprocating motion of the free piston are disclosed. A free piston position determining apparatus comprises a magnetic sensor disposed in a case containing a free piston, and a magnet disposed on the free piston. The magnet sensor generates pulse train when the magnet is positioned within a pre-determined distance form the magnet sensor. Stroke of the free piston is computed based on duration of the pulse, and offset of the average piston position from designed average position is computed based on interval of the pulse.
