    摘要： A bearing arrangement for a unit that is mutually turnable around a centre of rotation (R) comprising an external part (1) and an internal part (7), which, with the aid of high hydraulically acting pressure, is arranged to achieve a reciprocating rotary motion, or that is arranged to achieve a high hydraulic pressure from an applied torque from a reciprocating motion, whereby the external part (1) is provided with side walls arranged to axially surround at least a part of the internal part (7), and whereby the external part (1) comprises a radially inwardly arranged and essentially surrounding cavity (11, 12, 13, 14) in which the internal part (7) is arranged such that it can be rotated, which cavity (11, 12, 13, 14) is limited in the circumferential direction by at least one wing (3, 4) that protrudes inwards from the external part (1) and also limited by at least one wing (9, 10) that protrudes radially outwards from the internal part (7), which wings (3, 4, 9, 10) limit at least two chambers or compartments (11, 12, 13, 14) between the external part (1) and the internal part (7). At least one of the side walls of the external part is fixed connected with the, at least one, wing (3, 4) that protrudes radially inwards towards the internal part (7), which wing demonstrates a surface that faces radially inwards and that has a circular concave curvature for connection with an outwardly facing circular convex contact surface (8) at the internal part (7).

    摘要： Für den Aufbau von Regelkreisen zum Steuern von hydraulischen Arbeitselementen wie z.B. ein Hydromotor, Hydraulikzylinder oder dergleichen, wird eine neuartige hydraulische Steuereinrichtung beschrieben, die mit Soll-Wert-Vorgabe, z.B. mittels Schrittmotor, und mechanischer Ist-Wert-Rückmeldung arbeitet. Die Funktionsteile, die dazu dienen, den von einer Druckmittelquelle dem Arbeitselement zugeführten und von diesem zum Tank zurückfließenden Druckmittelstrom hinsichtlich Richtung und Menge feinfühlig zu regeln, sind als ineinanderliegende, gegenseitig verdrehbare Drehkolben (4, 6) ausgebildet. Dabei ist der eine Drehkolben (6) mit der Soll-Wert-Vorgabe (2) und der andere Drehkolben (4) mit dem Arbeitselement (3) zur mechanischen Ist-Wert-Rückmeldung drehschlüssig verbunden. Auf diese Weise können anders als bei den bekannten Steuereinrichtungen, bei denen über eine Längsbewegung Schieber oder Sitzventile betätigt werden, die Drehbewegungen von Soll- und Ist-Wert direkt miteinander verglichen werden. Hierdurch ist eine erheblich höhere Genauigkeit sowohl statisch (Positioniergenauigkeit, Rundlauf) als auch dynamisch (Folgetreue, Bahnabweichung) erreichbar. Außerdem ist die Steuereinrichtung überlastsicher, einfacher aufgebaut und preisgünstiger realisierbar.

    摘要： A hydraulic actuator comprises: a hydraulic cylinder 2; a piston 5 within the hydraulic cylinder 2 and movable in response to movement of hydraulic fluid in a hydraulic circuit coupled to the hydraulic cylinder 2; a synchronisation connection 14 for receiving an input from a simultaneous transmission line 14; and a valve 3 for controlling the flow of hydraulic fluid in the hydraulic circuit. The valve 3 is a rotary valve 3 comprising: a first valve section 16 arranged to rotate in either a first rotational direction or a second rotational direction in response to input from the simultaneous transmission line 14 in order to open a hydraulic flow path to the cylinder 2 and urge the piston 5 to move along the hydraulic cylinder 2 in a corresponding first linear direction or second linear direction; and a second valve section 18 arranged to rotate in either the first rotational direction or the second rotational direction; wherein the second valve section 18 is coupled to the piston 5 such that movement of the piston 5 results in movement of the second valve section 18 to follow the first valve section 16 and to close the hydraulic flow path when the rotation of the first valve section 16 is stopped.

    摘要： A precision servo control system for a pneumatic actuator has a piston (5) positionable over a stroke of the pneumatic actuator (2) using a supply of pressurized gas. A brake (52) and a sensor system (44) are connected to the actuator (2) and to the servo control system. The servo control system operates to initiate the forward thrust from the pressurized gas to move the piston (5) along the stroke. When a braking point along the stroke is determined, the servo control system initiates a reverse thrust from the pressurized gas while maintaining the forward thrust and simultaneously begins to selectively apply the brake (52) to stop the piston within a predetermined tolerance of a desired stopping position. The precision servo control system is easily programmable in a manner similar to that of a control system for electrical actuators. The precision servo control system can maintain the predetermined tolerance even under changing loads, long stroke lengths or vertically oriented stroke directions. The precision control servo system preferably utilizes simple directional valves, instead of complex and expensive servo valves, to regulate the pressurized gas. The precision servo control system achieves positional accuracy to a predetermined tolerance that is a fixed value, regardless of the stroke length.

    摘要： An electropneumatic rotary actuator (10) has proportional fluid valving (44) providing introduction and exhaust of pressurized fluid to and from a working chamber (45) of the actuator. By control of the admission angle and venting angle of the fluid pressure and flow with respect to top dead center and bottom dead center of a working piston (28) of the actuator both the torque level and gas consump­tion rates of the actuator may be controlled. Further by modulating the average working fluid pressure within the actuator the stiffness or resistance to backdriving of the actuator may be controlled. A proportional linear elec­trical solenoid (48-86) is disclosed and employed in the actuator of the present invention to drive a double-acting closed-centered valve device (88-116). Because of its lightweight, relatively simplicity, high stiffness to backdriving, and relatively low gas consumption rate, the present actuator is expected to find application in airborne vehicles.

    摘要： The bearing assembly, consisting of a stator component (S1) and a rotor component (R1), where the rotor component is adapted for a back-and-forth oscillatory movement (P, −P) relative to the stator component, whereby a number of cavities (301 and 302; 303 and 304) coordinated along the outer periphery of the rotor component and the inner periphery of the stator component, formed with an increasing volume (301 and 302) and a decreasing volume (303 and 304), respectively, during rotation of the rotor component in an initial direction (P) from an initial position (IP) and towards a final position (FP), while the cavities allow the volumes to decrease and increase during a rotational motion of the rotor component in a second direction (−P) in relation to the stator component (S1). The invention specifies that the above-mentioned bearing arrangement is to be adapted to interact with an instrument (M1) in order to determine, with the help of at least two components, the momentary position of the rotor component in relation to the stator component.
