    摘要： A hydraulic device can include two or more rings, a rotor having a plurality of vanes, and an adjuster. The two or more rings can be rotatably mounted within the hydraulic device and arranged adjacent one another configured for relative rotation with respect to one another. The rotor can be disposed for rotation about an axis within the two or more rings and can have a plurality of circumferentially spaced slots, each slot having at least one of the plurality of vanes located therein. The plurality of vanes can be configured to be movable between a retracted position and an extended position where the plurality of vanes work a hydraulic fluid introduced adjacent to the rotor. The adjuster can be configured to translate linearly to rotatably position the two or more rings relative to one another to increase or decrease a displacement of the hydraulic fluid between the rotor and the two or more rings.

    摘要： An object of the present invention is to provide a variable displacement vane pump capable of further reducing a pulse pressure. A vane pump (1) includes a cam ring (33). The cam ring (33) is annularly formed, and defines a plurality of pump chambers (38) on an inner peripheral side thereof in cooperation with a rotor (31) and vanes (32). An inner peripheral surface (330) of the cam ring (33) is formed in such a manner that, assuming that a confinement region refers to a region between an end portion of an intake port (221) and an end portion of a discharge port (222), at a timing when the pump chamber (38) communicates with or is disconnected from the discharge port (222) on one side corresponding to one of confinement regions or a timing close thereto, a change in a volume change amount of the pump chamber (38) on another side corresponding to the other of the confinement regions has an extreme value in a direction for reducing a change in a discharge amount at the time of the above-described communication/disconnection.

    摘要： The present invention provides a vane pump having variable displacement and high efficiency. The variable displacement vane pump includes a plurality of elongate, axially extending inserts disposed in the rotor. One of the inserts is disposed between every adjacent vane pair. The inserts are received within axially extending pockets in the rotor and are coupled to the rotor by springs. At lower rotational speeds, the inserts are retracted and the displacement of the pump chambers is at maximum. At higher rotational speeds, the inserts are advanced into the pump chambers, effectively reducing their displacement. Thus, the variable displacement pump compensates for the varying drive speed and achieves improved uniformity of fluid flow by providing maximum displacement at low speeds and reduced displacement at higher speeds.

    摘要翻译： 本发明提供了具有可变位移和高效率的叶片泵。 可变排量叶片泵包括设置在转子中的多个细长的轴向延伸的插入件。 一个插入件设置在每个相邻的叶片对之间。 插入件容纳在转子中的轴向延伸的凹穴内并且通过弹簧联接到转子。 在较低的转速下，插入件缩回，并且泵室的位移最大。 在更高的转速下，插入件进入泵室，有效地减少其位移。 因此，可变排量泵补偿了变速驱动速度，并且通过在较低速度下提供最大位移并且在较高速度下减小位移来实现改善流体流动的均匀性。

    摘要： A rotary hydraulic device of the displacement pump type having coaxial rotor and stator and vanes axially slidable in the rotor, the stator comprising at least one bottom surface formed with a variable number of deformations having rectilinear zones suitable for the operation on the recesses by the vanes. The recesses are made in movable elements of the stator such that the depth of the recesses can be made variable thus providing a device of variable capacity. The device is applicable to brakes and dampeners, as well as to engines and pumps.

    摘要： A hydraulic transmission or speed-change device or the like, of the type comprising a stator, an input rotor to which an input shaft is connected, and an output rotor to which an output shaft is connected, with expansible chambers between adjacent pairs of these members, is characterized by a flexible annulus fixed against rotation relative to one of the members but radially deformable relative thereto. Deformation of the annulus is effected by means of fluid pressure jacks that actuate wedges in a direction parallel to the common axis of rotation. At least some of the relatively movable portions of at least some of the expansible chambers slide against this annulus with a stroke that varies as the deformation of the annulus.
