    • The invention concerns an oscillator (1) for a timepiece movement, comprising a staff (12) rigidly connected to a balance (4) carrying first and second bipolar magnets (20, 40) spaced apart from the staff (12) and capable, depending on the angular position of the balance (4), of being positioned alternately within range of a magnetic field produced by a fixed bipolar magnet (28), the latter being located on the trajectory of the first and second bipolar magnets (20, 40) and being arranged in such a way that, when one of the bipolar magnets (20, 40) approaches the fixed bipolar magnet (28), identical polarities are located opposite each other in order to produce a repulsive force. The oscillator further comprises a pallet assembly (32) and an escape wheel (30) for establishing a kinematic connection between a source of energy of the timepiece movement and the balance staff (12), and arranged in such a way that the balance (4) is capable of having a sustained periodic oscillating movement of an amplitude greater than 90 degrees.
    • 本发明涉及用于钟表机芯的振荡器(1),包括刚性地连接到平衡物(4)的工作人员(12),平衡物承载与工作人员(12)间隔开的第一和第二双极磁体(20,40),并且能够 在所述摆轮(4)的角位置上交替地定位在由固定双极磁体(28)产生的磁场范围内,所述固定双极磁体(28)位于所述第一和第二双极磁体(20,40)的轨迹上, 并且以这样的方式布置,即当双极磁体(20,40)中的一个接近固定双极磁体(28)时,相同的极性彼此相对定位以产生排斥力。 该振荡器还包括托盘组件(32)和擒纵轮(30),用于建立钟表机芯能量源与摆轮工作人员(12)之间的运动学连接,并且以这样的方式布置,即摆轮(4 )能够具有幅度大于90度的持续的周期性振荡运动。
