Throttle for adjusting valve - has actuating rod sliding for limited amount in body to open or shut throttle passage

摘要

The adjusting valve has a throttling body, particularly a perforated cylinder, through which flow takes place in the closing direction. It is coupled by a rod to an actuating mechanism and seals off two pressure chambers from each other. The rod (6) slides for a limited amount (a) in the axial direction in relation to the body (2). One or more throttle drillings (15, 16) connect the pressure chambers (3, 5) together and before opening or shutting the valve by the body they are opened or shut by the relative movement between bar and body.
