Abstract:
1. An adjusting device for a valve, comprising an axially displaceable control member on which a control spring acting on a valve body is supported and which is in rotational engagement with a catch which is, or can be, fixedly connected to a handle for adjusting a control spring biasing, wherein the catch has a radially projecting locking member associated with a recess on the handle into which the locking member can be inserted and in which, by a relative movement, the locking member can be brought into an axial locking position in which the locking member is positioned between two shoulders of the recess, wherein the locking member is an annular locking collar extending radially outward, wherein the recess or the locking collar is eccentric, wherein the recess is eccentric with respect to the valve axis and opens into a face of the sleeve and is radially extended at a distance from the face of the sleeve by a puncture forming the shoulders, wherein the outer diameter of the annular locking collar is somewhat smaller than an opening diameter of the recess so that the locking collar can be inserted in the recess, and after the relative movement, is disposed in portions between the shoulders of the puncture, wherein the locking collar is confined on one side by an annular groove.
