摘要： 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 ωp ω p  1 - α p k p and the natural frequency of oscillation of the piston, ∩p, 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.

摘要： 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).

摘要： The invention can prevent gas leakage and reduce friction force while relaxing tolerance for manufacturing a displacer and the like for Stirling cycle machines. Gas leakage between the outer periphery of a seal (1) and the inner peripheral surface (5a) of a cylinder (5) is prevented. Accordingly, precise finish of the radial clearance between the displacer (2) and the cylinder (5) is not required. As the difference of pressures between the front and rear spaces of the displacer (2) is small, the gas leakage is sufficiently prevented without pressing the seal (1) against the inner peripheral surface (5a) of the cylinder (5). On the other hand, as the friction force generated between them is significantly small, it does not affect the reciprocation of the displacer. As the seal (1) is provided so as not to be restricted axially and radially, the displacer is kept closely contacted with the inner peripheral surface (5a) of the cylinder (5) even if the displacer (2) eccentrically shifts.
摘要翻译：本发明可以防止气体泄漏并减小摩擦力，同时放松用于制造用于斯特林循环机器的置换器等的公差。防止了密封件（1）的外周与气缸（5）的内周面（5a）之间的气体泄漏。因此，不需要在置换器（2）和气缸（5）之间的径向间隙的精确精加工。由于置换器（2）的前后空间之间的压力差小，所以在将密封件（1）压靠在气缸（5）的内周面（5a）上的情况下，充分防止了气体泄漏。另一方面，由于它们之间产生的摩擦力非常小，所以不影响置换器的往复运动。由于密封件（1）设置成不受轴向和径向的限制，所以即使置换器（2）偏心移动，排液器也保持与气缸（5）的内周面（5c）紧密接触。

摘要： To provide a less expensive and high-efficient free-piston Stirling cycle machine with an outer diameter of entire machine being relatively small. In a Stirling cycle cooler as a free-piston Stirling cycle machine including a cylinder 7, a piston 18 which is reciprocable inside said cylinder 7 and an electromagnetic driving mechanism 19 for reciprocating said piston 18, said electromagnetic driving mechanism 19 is comprised of a mover 20 and a stator 35, said piston 18 and said mover 20 formed by disposing a permanent magnets 24 outside an inner yoke 23 made of magnetic flux conducting material are disposed in an axial alignment, and said stator 35 and said cylinder 7 are disposed in an axial alignment. By this disposition, the outer diameter Rm of said mover 20 of said electromagnetic driving mechanism 19 can be reduced, and consequently the inner diameter Rs and the outer diameter of said stator 35 provided outside said mover 20, eventually the outer diameter of entire Stirling cycle cooler can also be reduced.

摘要： An improved, free-piston, Stirling machine having at least three pistons series connected in an alpha Stirling configuration. Each cylinder is stepped so that it has a relatively larger diameter interior wall and a coaxial, relatively smaller diameter interior wall. Each piston is also stepped so that it has a first component piston having an end face facing in one axial direction and matingly reciprocatable in the smaller diameter cylinder wall and a second component piston having an end face facing in the same axial direction and matingly reciprocatable in the larger diameter, cylinder wall. One of the piston end faces bounds the compression space and the other end face bounds the expansion space. Preferably, each stepped piston has peripheral, cylinder walls that are axially adjacent and joined at a shoulder forming the end face of the larger diameter component piston. Stirling machines with these stepped features are also arranged in various opposed and duplex configurations, including arrangements with only one load or prime mover for each opposed pair of pistons. Improved balancing or vibration reduction is obtained by connecting expansion and compression spaces of a four cylinder in-line arrangement in a 1, 3, 2, 4 series sequence. Three cylinder embodiments provide a highly favorable volume phase angle of 120° and are advantageously physically arranged with three, parallel, longitudinal axes of reciprocation at the apexes of an equilateral triangle.
