Abstract
To avoid acoustic instabilities and the mechanical stresses on the valve structure induced by these instabilities, the valve cone (11) downstream of the narrowest cross-section of passage of the valve opening and the diffusor (13, 14) are provided with separation edges (15, 16). The flow passage furthermore has no convex boundaries. <IMAGE>
