초록

A flow control valve, especially for use in controlling the operation of a steam turbine, includes a valve seat arranged in the interior of a valve housing, and a diffusor arranged downstream of the valve seat, as well as a valve member which is mounted in a valve member guide toward and away from the valve seat to accordingly throttle the flow of steam or a similar medium through the interior of the valve housing and into the diffusing channel of the diffusor. Minimization of alternating forces tending to excite the valve member into oscillating and sta...
