Breathing valve, for breathing mask, has valve pin and optionally valve plate made of material with rubber-elastic properties to dampen vibrations

摘要

The valve has a valve plate (2) held by spring pressure on a valve seat and having a valve pin (1) made of a material with rubber-elastic properties to dampen vibrations. The valve pin and valve plate can be made from the same material. The valve pin is guided in a linear slide bearing which can also be made of a material with rubber elastic properties.
