    • The invention relates to a turbocharger comprising a turbine housing 1, a bearing housing 2, a rotatably mounted turbine wheel 3 rotating about an axis 3.2 and a guide apparatus 5 comprising a plurality of guide vanes 5.2 rotatably mounted in pivot bearings 5.4 at a guide vane support 5.1 for influencing the flow in a flow channel 9 of the turbine housing 1, and comprising a spring element for forcing the guide apparatus 5, which moves in the axial direction, against a wall 1.1 of the turbine housing 1. It is proposed that two disc springs 6, 7 be placed between the guide apparatus 5 and the bearing housing 2, one end 6.1, 7.1 of said springs being supported at the guide apparatus (5), wherein a first disc spring 7 is located in the radial direction between the rotational axis 3.2 of the turbine wheel 3 and the pivot bearings 5.4 of the guide vanes 5 and a second disc spring 6 is located in the radial direction on the side of the pivot bearing 5.4 away from the rotational axis 3.2 of the turbine wheel and wherein the disc springs 6, 7 seal off a displacement chamber 8 provided with a displacement mechanism 10 of the guide apparatus 5 against the flow channel 9.
    • 本发明涉及一种具有一个涡轮机壳体1,一个轴承壳体2,一个围绕轴线3.2可旋转地安装在涡轮增压器涡轮机轮3和具有多个在枢轴轴承5.4旋转地安装在导向叶片载5.1上的导向装置5叶片5.2中的一个流动通道9影响流动 涡轮机壳体1和与作用于所述轴向可移动的导向装置5抵靠涡轮机壳体1.1的壁的弹簧元件。1 本发明提出,被布置在扩散器5和轴承壳体2,两个板簧6,图7,其通过它的一个端部6.1,7.1在分配器(5),支撑之间,其中,第一板弹簧7在旋转轴3.2之间的径向方向 涡轮机轮3和枢轴轴承叶片5 5.4被布置和第二板弹簧6在从旋转轴线的枢转轴承的涡轮叶轮侧的3.2远程侧的径向方向被设置5.4,并且其中所述盘簧6,7一到分配器5的调整机构10 调整空间提供了针对流动通道8密封。9
