A reversible hydraulic pump (12) for setting the pitch of a propeller (3) of a turbine thruster (2) comprises two barrels (20, 21) connected by a driveshaft (28). The first and second cylinders (20, 21) are connected to the driveshaft (28) via first and second clutch means (29, 30) such that only the first cylinder is rotated by the driveshaft when the driveshaft is rotated in a first direction and such that only the second cylinder is rotated by the driveshaft when the driveshaft is rotated in a second direction opposite the first direction.

    一种用于设定涡轮推进器(2)的螺旋桨(3)桨距的可逆液压泵(12),该可逆液压泵包括通过传动轴(28)连接的两个筒体(20,21)。第一和第二筒体(20,21)经由第一和第二离合器装置(29,30)连接到传动轴(28),使得当传动轴在第一方向上旋转时,仅第一筒体由传动轴旋转,并且使得当传动轴在与第一方向相反的第二方向上旋转时,仅第二筒体由传动轴旋转。
