Rotary valve with compensating element for compensating for axial offset

The invention relates to a valve (300) for separating a component of a sample liquid introduced into a mobile phase, preferably in a high performance chromatography system (10), having a rotor (210) and a stator (220), a flow path being established or blocked by a rotational movement of the rotor (210) relative to the stator (220), and having a compensation element (310) for compensating the component of the sample liquid introduced into the mobile phase, the compensating element, together with the rotor (210) and the stator (220), is arranged in the axial direction and, in the operating state of the valve (300), enables an axial compression of the rotor (210) relative to the stator (220). The compensation element (310) has at least one spherical surface (320) in order to compensate for an axial offset between the rotor (210) and the stator (220). 本发明涉及一种优选在高效色谱分析系统(10)中用于分离引入到移动相中的样品液体的成分的阀(300)，该阀具有转子(210)和定子(220)，其中通过转子(210)相对于定子(220)的旋转运动可以建立或阻止通流路径，并且该阀具有补偿元件(310)，该补偿元件连同转子(210)和定子(220)在轴向上布置并且在阀(300)的运行
