    • The invention concerns a hydraulic machine with a set of teeth, having a toothed ring with an inner toothing and a gear wheel with an outer toothing, the gear wheel rotating and orbiting in the toothed ring, the inner toothing and the outer toothing touching each other in contact areas, thus separating pressure chambers, and with a valve arrangement controlling a connection between a connection arrangement having a high pressure connection and a low pressure connection, and the pressure chambers. It is endeavoured to achieve a stable operation, particularly with low speeds. For this purpose, each contact area is provided with an opening, which, at the time when a pressure chamber reaches an extreme value of its volume, produces a short-circuiting with the neighbouring pressure chamber.
    • 本发明涉及一种具有一组齿的液压机械,其具有带有内齿的齿形环和具有外齿的齿轮,所述齿轮在齿环中旋转和绕动,所述内齿和外齿彼此接触 在接触区域中,从而分离压力室,并且与控制高压连接的连接装置和低压连接之间的连接的阀装置以及压力室。 努力实现稳定运行,特别是低速运行。 为此,每个接触区域设置有一个开口,当开口压力达到其体积的极值时,该开口产生与相邻压力室的短路。
