Claim 0:
1. A pressure control valve for gases and/or liquids comprising:
a first sealing body for opening and closing a first flow path between an inflow and an outflow for gases and/or liquids and
a second sealing body between the inflow and the outflow for opening and closing a second flow path, the first and the second flow paths being arranged concentrically with different nominal widths,
wherein the first and the second sealing bodies are designed so as to be installed in the inflow for gases and/or liquids and to define the first and the second flow paths therein, the first and the second sealing bodies being arranged concentrically to one another and concentrically to the two flow paths,
wherein the first sealing body is designed so as to be moved by a force of an actuating device with an effective direction from the outflow to the inflow from a closing position into an opening position in which the first flow path is opened, and the second sealing body is designed so as to be moved by a force of the actuating device with an effective direction from the outflow to the inflow from a closing position into an opening position in which the second flow path is opened, wherein the first sealing body is constructed in one piece, wherein the second sealing body is constructed in one piece,
wherein the first sealing body being guided in an axially movable fashion within a housing and the second sealing body being guided in an axially movable fashion within the first sealing body, wherein the two sealing bodies are coupled to one another by a driver formed on at least one of the two sealing bodies, the first sealing body comprising a first sealing seat and the second sealing body comprising a second sealing seat,
wherein the second sealing body is designed so as to be charged directly with a compressive force with an effective direction from the outflow to the inflow for moving from the closing position into the opening position, and the first sealing body is designed so as to be charged indirectly with a compressive force with an effective direction from the outflow to the inflow for moving from the closing position into the opening position, wherein the driver being designed for transmitting the compressive force exerted on the second sealing body onto the first sealing body,
wherein the first sealing body comprises one or several cutouts for supplying the high-pressure gas to the first sealing seat and the second sealing seat and for the assembly of the second sealing body within the first sealing body.
