Valve for use as e.g. servo valve in electro-pneumatic position regulator, has O-ring-seal sealing intermediate space between sealing body and bearing for body on shaft, where body includes thin-walled elastic material in sealing region

摘要

The valve has a fluid passage (3) closed by a valve body (4) displaceable in an axial direction. A sealing body (5) is provided for tolerance compensation relative to inclination of an axis (15) of the valve body relative to center axis (16) of the passage. The sealing body includes ball-shaped scrapper shape at an external side. A O-ring-seal (10) seals an intermediate space between the sealing body and a bearing for the sealing body on a shaft (6), and is arranged on a sealing body's side facing the passage. The sealing body includes a thin-walled elastic material in a sealing region.
