    • An anesthetic evaporator with a pressure control circuit has a differential pressure pick-up (18) can be calibrated in a simple manner. A switchover device (20) is provided according to the present invention at a bypass gap (3), which is designed to connect the gas inlet (4) directly with the gas outlet (5) via a first bypass line (23) and to bridge over the bypass gap (3) via a second bypass line (26) connected to a ventilation duct (27) in a first switching position. The gas flow from the gas inlet (4) to the gas outlet (5) is established via the bypass line (2) in a second switching position. The calibration of the differential pressure pick-up (18) with the pneumatic connections (16, 17) is performed in the first switching position of the switchover means (20) via the ventilation duct (27), which is open toward the ambient atmosphere.
    • 具有压力控制电路的麻醉蒸发器具有差压检测器(18),可以以简单的方式进行校准。 根据本发明的切换装置(20)设置有旁通间隙(3),其被设计成经由第一旁通管线(23)将气体入口(4)直接与气体​​出口(5)连接,并且 通过连接到第一切换位置的通风管道(27)的第二旁路管线(26)跨越旁路间隙(3)。 在第二切换位置通过旁路管线(2)建立从气体入口(4)到气体出口(5)的气流。 利用气动连接(16,17)对差压检测器(18)进行校准,是在切换装置(20)的第一切换位置经由向周围大气开放的通风管道(27)进行的 。
