摘要： A hydraulic transformer (1) comprises a housing (2) including a high-pressure connection (3), a low-pressure connection (4) and an operating pressure connection (5), a barrel member (19, 20) which is rotatably mounted in the housing (2) and provided with a plurality of compression chambers of which the volume changes upon rotating the barrel member (19, 20). A back side (24) of the barrel member (19, 20) includes barrel ports (27) which communicate with the respective compression chambers. The hydraulic transformer (1) has a face plate (28, 29) which is supported by the housing (2) and provided with a front side (30) that supports the back side (24) of the barrel member (19, 20), a back side (31) that faces the housing (2), a circumferential outer wall and a central hole (49) that is surrounded by a circumferential inner wall. The face plate (28, 29) is rotatable with respect to the housing (2) within a predetermined angle, wherein the front side (30) is provided with three arcuate face plate ports along which the barrel ports (27) travel upon rotating the barrel member (19, 20). The face plate ports communicate with the high-pressure connection (3) through a first passage (35) in the face plate (28, 29), the low-pressure connection (4) through a second passage (36) in the face plate (28, 29) and the operating pressure connection (5) through a third passage (37) in the face plate (28, 29), respectively. One of the first to third passages (35, 36, 37) has an opening at the back side (31) of the face plate (28, 29), one of the first to third passages (35, 36, 37) has an opening at the circumferential outer wall of the face plate (28, 29) and one of the first to third passages (35, 36, 37) has an opening at the circumferential inner wall of the face plate (28, 29).

摘要： A hydraulic rotating axial piston engine, having a housing (2), enclosing a rotatable cylinder barrel (11), having a number of axial cylinders (13) with a number of reciprocating pistons (12). The pistons reciprocate between two defined end positions, and cooperate with an angled plate (21) in order to obtain the reciprocating movement. Cylinder barrel is rotatable relative to a first axis (10), which is inclined relative to a second axis (9) of an input/output shaft (8), and the plate is rotatable together with said input/output shaft around the second axis. The rotation of the cylinder barrel and the input/output shaft is synchronized by means of synchronizing means (22, 23). A central support pin (24) extends along the first axis between the angled plate and the cylinder barrel, and the housing has two parts, one part (3) of the housing positions the input/output shaft and a second part (4) includes inlet and outlet channels. The support pin (24) is in one end axially connected with the angled plate (21) and in the other end (28) axially connected to the cylinder barrel (11). The support pin limits axial movement at the cylinder barrel relative to the angled plate.

摘要： A pressure exchanger and a method for pressurising a first fluid by the pressure of a second fluid wherein each fluid influences surface areas of a sliding member individually. Due to differences in sizes of the surface areas, the first fluid can be pressurised to a pressure which is different from the pressure of the second fluid. The invention further provides a reverse osmosis desalination system with an RO membrane, an intake leading seawater into the chamber, and an outlet leading brine out of the chamber, wherein the seawater is pressurised by the brine in a pressure exchanger of the above mentioned kind.

摘要： Kennzeichnend für diese Kolbenmaschinen ist das Fehlen jeglicher Lager zur Kraftübertragung innerhalb der Maschinen. Starre Verbindungen zwischen Kolben (1) und einer Welle werden durch zum Hub querbewegliche Zylinder möglich.
Bei starr zusammengefaßten Zylindern (2) werden die Kolben (1) durch querelastische Kraftübertragungsteile (15;16;17;18;20) mit einem Kolbenträger (11) formschlüssig verbunden.
Kolben und Zylinder können beliebige Formen annehmen, meist ist der Kolben kugelförmig, bzw. sphärisch.
Diese Grundidee läßt sich auf alle Kolbenmaschinen anwenden, bei denen Axial- Radial- und Taumelkolbenmaschinen die Eckpunkte darstellen und ist für alle Arbeitsprozesse geeignet, die ein Verdrängerprinzip zur Grundlage haben, bei denen beliebige mechanische, hydraulische und pneumatische Größen ineinander umgewandelt werden, d.h., diese Erfindung bezieht sich nicht nur auf Pumpen, Verdichter und Motoren, sondern auch auf hydrostatische Kupplungen u.dgl.

摘要： Die Erfindung betrifft eine Axialkolbenmaschine in Schrägscheibenbauweise, deren von der Triebwelle durchsetzte Schrägscheibe um eine wirksame Schwenkachse derart schwenkbar ist, daß ihre die Kolben abstützende Wirkfläche während einer Verschwenkung eine bezüglich der Triebwelle radiale Bewegungskomponente aufweist, in deren Richtung sich die wirksame Schwenkachse während der Schrägscheiben-Verschwenkung parallel verlagert.

摘要： A power transfer unit coupling two otherwise separate hydraulic systems for bidirectional transfer of hydraulic power therebetween without transfer of fluid between the two systems. The unit comprises power transfer apparatus characterised in that it comprises a first variable displacement fluid pump-­motor unit (50) having associated high and low pressure fluid ports (34,36) for connection to a first pressure fluid source (14), and a first rotary shaft (66) the first unit (50) being operable to convert energy between pressurised fluid flow and mechanical rotation of the first shaft (66); a second fixed displacement fluid pump-motor unit (68) also having associated high and low pressure fluid ports (42,44) for connection to a second pressure fluid source (14ʹ) and a second rotary shaft (80), the second unit (68) being operable to convert energy between pressurised fluid flow and mechanical rotation of the second shaft (80), the first and second shafts (66,80) being mechanically interconnected for common rotation to transmit power between the first and second units (50,68) without mixture of their respective fluids; and control means (32) for adjusting the displacement of the first unit (50), the control means (32) being responsive to the pressures of the high pressure ports (34,42) of both the first and second units (50,68) and being operable to maintain the pressure differential therebetween below a preselected level whenever the first and second shafts (50,68) are rotating.

摘要： Machine à piston du genre où un assemblage (1) de cylindres est disposé de manière équidistante autour d'un premier axe de rotation (x) et un assemblage de pistons correspondant (4) est disposé de manière équidistante autour d'un second axe de rotation (y) qui est fixe ou est incliné de manière variable par rapport au premier axe de rotation (x), chaque piston (4) comprenant une bague (4A) pouvant se déplacer latéralement par rapport au piston lui-même pour que la bague (4A) puisse de déplacer sensiblement de manière rectiligne par rapport au cylindre correspondant tandis que le piston lui-même se déplace sur un chemin courbe par rapport à celui-ci. Chaque cylindre (1) communique, via une portion conique ou étagée (15) de celui-ci, avec une surface annulaire (14) d'un dispositif de support non rotatif (3) de l'assemblage (1) de cylindres de sorte que, lorsqu'une pression positive ou négative existe dans le volume de travail défini par chaque cylindre (1) et chaque piston correspondant (4), la réaction de poussée est largement transférée sur la surface annulaire (14) du dispositif de support (3). Chaque piston (4) possède un passage (11) traversant qui communique de manière répétée, pendant l'utilisation de la machine, avec les conduits d'admission et de sortie (13) au moyen de lumières en forme de banane (10) aménagées dans la surface d'étanchéité (9) entre un rotor (5) qui porte les pistons (4) et une enceinte (7) de la machine. Des éléments résilients (4B) sont interposés entre les bagues (4A) et les pistons eux-mêmes qu'ils entourent pour empêcher les chocs périodiques se produisant lors du fonctionnement.
