Measuring gas and respiration gas guiding device for respiratory system, has valve block with housing to receive seal ring that is pressed against sealing seat, where block allows permanent passage of gas in two flow directions

摘要

The device has a valve block (26) with a housing to receive a seal ring (21) that is pressed against a sealing seat (20) during a zero adjustment. A valve seat (22) and a retention element (24) maintain a membrane (23) in position, and a spring (28) moves the block arranged in a rod (27) in an axially movable manner, where the block allows permanent passage of gas in a flow direction by a determined pressure and in another flow direction. Independent claims are also included for the following: (1) a method for desiccating measuring gas (2) a device for desiccating measuring gas (3) a method for cooling electrical apparatuses with compressed gas (4) a respiration gas bringing apparatus comprising a gas outlet and a gas inlet.
