摘要： A linear compressor employing a piezoelectric actuator operating in resonance at a frequency substantially below its natural resonant frequency, which is usually of the order of 10kHz. Low frequency resonance operation of the actuator, of the order of 100 Hz., is achieved by incorporating the actuator and its housing with the moving compression piston, such that the moving mass is substantially increased, and by reduction of the effective piezoelectric stiffness using hydraulic amplification of the actuator displacement. Both these procedures result in a reduction of the actuator resonant frequency. The hydraulic amplification is achieved by using a hydraulic chamber with different sized pistons, linking the actuator motion with motion of the actuator housing, to which the compressor piston is attached. The high efficiency achieved and the lack of moving parts or the need for lubricating oil makes the compressor ideal for use in high reliability and high purity applications.
摘要翻译： 一种采用压电致动器的线性压缩机，其频率基本上低于其固有谐振频率的谐振，其频率通常为10kHz量级。 通过将致动器及其壳体与移动的压缩活塞并入，实现致动器的低频共振操作，大约为100Hz，使得移动质量基本上增加，并且通过使用液压降低有效的压电刚度来实现 致动器位移放大。 这两个过程都会导致执行器谐振频率的降低。 通过使用具有不同尺寸活塞的液压室，将致动器运动与致动器壳体的运动相连接，压缩机活塞附接到液压室。 实现高效率，缺少运动部件或需要润滑油使压缩机非常适用于高可靠性和高纯度应用。

摘要： A fluid machine is shown and described for compressing or conveying fluids, in particular for compressing gases to high pressures, with a linear motor (2), at least one cylinder (3), a solid piston (4) which can be moved axially in the cylinder (3) or a liquid piston (4') which can be moved axially, and at least one compression space (5) which is formed between the cylinder (3) and the solid piston (4) or the liquid piston (4'), wherein the linear motor (2) transfers a translatory driving force to the solid piston (4) or to the liquid piston (4'). For such a fluid machine, the leakage-free and lubricant-free compression and conveying of fluids, in particular a compression of gases to high pressures, and a rather simple construction is made possible owing to the fact that the solid piston (4) and/or the liquid piston (4') is surrounded in the area of the linear motor (2) by a firmly attached opening pipe (6).

摘要： In a reciprocating piston compressor (1) comprising at least one first compression stage (11) for compressing a first gas, the first compression stage (11) comprises at least a first piston (13) sliding in a first compression (12) chamber. The compressor (1) further comprises at least one second compression stage (21) for compressing a second gas, the second compression stage (21) comprising at least a second piston (23) sliding in a second compression chamber (22), and the second and the first piston (13, 23) being mechanically linked and driven by the same mechanical actuator (31). The first and second gas are, within the compressor (1), kept separate from one another.
This makes it possible to compress two gases, separate from each other in the same compressor (1). In a preferred embodiment of the invention, the volume ratio of the first and second compression stage (11, 21) is the same as the stoichiometric ratio of the gases produced by a separation process coupled to the compressor (1)摘要翻译： 在包括用于压缩第一气体的至少一个第一压缩级（11）的往复活塞式压缩机（1）中，所述第一压缩级（11）至少包括在第一压缩（12）室中滑动的第一活塞（13）。 压缩机（1）还包括用于压缩第二气体的至少一个第二压缩级（21），第二压缩级（21）包括在第二压缩室（22）中滑动的至少第二活塞（23） 第二活塞（13,23）由相同的机械致动器（31）机械连接和驱动。 第一和第二气体在压缩机（1）内保持彼此分离。 这使得可以在相同的压缩机（1）中压缩彼此分离的两种气体。 在本发明的优选实施例中，第一和第二压缩级（11,21）的体积比与由与压缩机（1）连接的分离过程产生的气体的化学计量比相同，

摘要： An oxygen concentrator is utilized in combination with a compressor to provide a highly enriched and compressed oxygen gas in a mobile container such as a gas cylinder. The combination and method of production provides for the facile preparation of an enriched source of oxygen for use by an ambulatory or wheelchair-confined patient. The oxygen concentrator utilizes two or more molecular sieves to provide a breathable gas of from approximately 80 to about 98 percent oxygen from atmospheric air. The oxygen-enriched gas is stored in a concentrator product tank and can be prioritized so as to supply a patient with a proper amount and concentration of oxygen and secondarily to supply any surplus or excess enriched oxygen to a compressor. The compressor utilizes multiple stages to produce the highly compressed oxygen-enriched gas and utilizes a two-part piston at low rpm to enhance low wear and low noise. The multiple pistons of the compressor can either all rotate at one RPM or in an alternative embodiment, at least a first piston can rotate at a higher RPM than any remaining pistons. Desirably, at least the initial piston of the alternative embodiment is driven by one drive shaft source with one or more other remaining pistons being driven by a second drive shaft.
