Abstract
A valve device, especially for die casting machines. The device comprises a control drive and a control member which is arranged between the control drive and the valve cone, and which converts the rotary movement of the control drive into an axial stroke movement. The object of the invention is to provide a quick acting valve device with which the adjustable limited opening of the valve cone can, with the aid of small manual or motor forces, be effected with structurally simple means in a space saving device housing in the direct drive. For this purpose, the control member which serves to adjust the opening limitation of the valve cone is a threaded sleeve which engages in a thread of the valve housing. Every time the working surfaces of the valve cone are acted upon by pressure, different hydraulic pressures are exerted upon the oppositely located end faces of the threaded sleeve for releasing the sides of the threads of the sleeve from the sides of the threads of the housing.
