    • Proposed is a valve (1) for controlling volume flows of a coolant in a heating and/or cooling system of a motor vehicle, having a valve housing (10, 12, 14, 25) with at least one inlet duct (18) and with at least one outlet duct (20, 22), wherein in the valve housing (10, 12, 14) there is provided at least one valve disc (28) which is arranged so as to be rotatable about the axis (31) of a shaft (30) and which influences the connection between the at least one inlet duct (18) and the at least one outlet duct (20, 22) of the valve (1). According to the invention, a radially displaceable sealing sleeve (72) is arranged between the at least one outlet duct (20, 22) and the valve disc (28), via which sealing sleeve the at least one inlet duct (18) and the at least one outlet duct (20, 22) can be connected to one another, by radial displacement of the sealing sleeve (72), in the event of overheating of the coolant.
    • 提出了一种用于控制机动车辆的加热和/或冷却系统中的冷却剂的体积流量的阀(1),该阀具有带有至少一个入口导管(18)的阀壳体(10,12,14,25)和 (20,22),其中在所述阀壳体(10,12,14)中设置有至少一个阀盘(28),所述阀盘布置成能够围绕所述阀芯的轴线(31)旋转, 轴(30)并且影响所述阀(1)的所述至少一个入口管道(18)与所述至少一个出口管道(20,22)之间的连接。 根据本发明,在至少一个出口导管(20,22)和阀盘(28)之间设置径向可移位的密封套筒(72),密封套筒通过该密封套筒与至少一个入口导管(18)和 在冷却剂过热的情况下,通过密封套筒(72)的径向位移,至少一个出口管道(20,22)可以彼此连接。
