Claims4
A device for vulcanization of tire blanks, comprising:
- at least one heatable mold for receiving the tire blank;
- at least one controllable supply device for a heating medium, the supply device having one inlet valve and one outlet valve, wherein the inlet valve has a first positioning device that is actuated by a liquid fluid, wherein the outlet valve has a second positioning device that is actuated by the liquid fluid, wherein the first positioning device includes a first piston-cylinder assembly and the second positioning device includes a second piston-cylinder assembly;
- and a pump to deliver the liquid fluid from a tank to the first and the second piston-cylinder assemblies and for a pressure buildup, wherein the pump is coupled to the tank, and wherein the inlet valve is connected to a first control valve by a first control line for actuating the inlet valve and the outlet valve is connected to a second control valve by a second control line for actuating the outlet valve, wherein the first control valve and the second control valve are 3/2-way valves.
