    Abstract: An HME device, used in a closed breathing circuit of a ventilation system, has a housing with an inlet opening and with an outlet opening, an HME chamber (50a; 50b; 50c; 50d; 50e; 50f; 50g; 50h; 50i) arranged between the inlet opening and the outlet opening for receiving an HME medium and a switching mechanism (70a; 70b; 70c; 70d; 70e; 70f; 70g; 70h; 70i). The HME device can be switched over between an HME mode (M1), in which an HME fluid passage is provided from the inlet opening through the HME chamber to the outlet opening, and a bypass mode (M2), in which a fluid bypass passage is provided from the inlet opening past the HME chamber through a bypass channel (80a; 80b; 80d; 80e; 80f; 80h) in the housing to the outlet opening. The bypass channel is blocked with respect to the HME chamber in the bypass mode (M2).

    Abstract: A flowmeter comprises a lower valve body (1), a throttle assembly, a flow tube assembly, an upper valve body (2), and a pressure fluctuation suppression assembly. An air inlet, an air outlet and an air flow channel connecting the air inlet and the air outlet are arranged in the lower valve body (1); a throttle assembly for adjusting the degree of opening of the air flow channel in the lower valve body (1) is further disposed on the lower valve body (1). The flow tube assembly comprises a flow tube (3), an upper base (4), a lower base (5), and a float (6); a vent hole is provided on each of axial centers of the upper base (4) and the lower base (5); the lower base (5) is arranged at the air outlet of the lower valve body (1); a vertical air flow passage and a horizontal air flow passage are arranged in the upper valve body (2); the upper base (4) is arranged at an air inlet of the vertical air flow passage in the upper valve body (2); the flow tube (3) is disposed between the upper base (4) and the lower base (5) through two ends thereof that are respectively sleeved on protruding portions of the upper base (4) and the lower base (5); the float (6) is disposed in the flow tube (3). The pressure fluctuation suppression assembly comprises a sealing gasket (7), and the sealing gasket (7) is disposed at an air outlet of the vertical air flow passage.

    Abstract translation: 流量计包括下阀体（1），节流阀组件，流管组件，上阀体（2）和压力波动抑制组件。 在下阀体（1）中设置有空气入口，出气口和连接空气入口和空气出口的空气流通道; 用于调节下阀体（1）中的空气流动通道的开度的节气门组件进一步设置在下阀体（1）上。 流管组件包括流管（3），上基座（4），下基座（5）和浮子（6）; 在上部基座（4）和下部底座（5）的各轴心上设置通气孔; 下底座（5）布置在下阀体（1）的出气口处; 在上阀体（2）中设置有垂直空气流通道和水平空气流通道; 上基座（4）设置在上阀体（2）中的垂直空气流动通道的进气口处; 流量管3通过其上端分别套在上基座4和下基座5的突出部分上而设置在上基座4和下座5之间。 浮子（6）设置在流量管（3）中。 压力波动抑制组件包括密封垫圈（7），并且密封垫圈（7）设置在垂直空气流动通道的空气出口处。
