The invention relates to a tyre valve (10) for filling and emptying a motor vehicle tyre, which tyre valve comprises a hollow valve body (12) delimiting a receiving space (13). The valve body (12) hasan inlet opening (18) communicating with the receiving chamber (13) and an outlet opening (20) arranged axially offset with respect to the inlet opening (18) and communicating with the receiving chamber (13), a valve bolt (14) axially slidably received in the receiving chamber (13) of the valve body (12), a restoring spring (16) supported on the valve body (12) and acting on the valve bolt (14),the valve bolt (14) being contoured in such a way that in a first position for closing the motor vehicle tyre in a second position axially displaced with respect to the first position for emptying themotor vehicle tyre both the inlet opening (18) and also the outlet opening (20) are opened and in a third position axially displaced with respect to the first position and the second position for filling the motor vehicle tyre, the inlet opening (18) is opened and the outlet opening (20) is closed. As a result a cost-effective filling and emptying of a motor vehicle is made possible with low design expenditure.

    规定了一种用于机动车轮胎充气和放气的轮胎充气阀(10),它包含限定安装空间(13)的空心阀体(12),其中,所述阀体(12)具有与所述安装空间(13)连通的入口(18)和以与所述入口(18)轴向错开的方式布置的、与所述安装空间(13)连通的出口(20);以可轴向移动的方式容纳在所述阀体(12)安装空间(13)中的阀销(14);支撑在所述阀体(12)上并作用在所述阀销(14)上的复位弹簧(16),其中,所述阀销(14)按如下方式设计,即:在用于封闭机动车轮胎的第一位置中,不管是所述入口(18)还是所述出口(20)都是关闭的,在与所述第一位置轴向错位的、用于机动车轮胎放气的第二位置中,不管是所述入口(18)还是所述出口(20)都是打开的,并且在与所述第一位置和第二位置轴向错位的、用于机动车轮胎充气的第三位置中,所述入口(18)是打开的,所述出口(20)是关闭的。由此可以利用简单的设计低成本地进行机动车轮胎的充气和放气。
