摘要:
The valve device for venting die-casting moulds has a valve housing and a venting duct running between an inlet and an outlet. A force-receiving element, which is actuated by casting material, and at least two venting valves, which are operatively connected to the force-receiving element, are arranged in the venting duct. Each venting valve comprises a valve piston. The force-receiving element is provided with radial protrusions, which engage in a corresponding cut-out in the respective valve piston and effect a direct coupling between the respective venting valve and the force-receiving element.
