Abstract
A device for controlling fluid media, such as a directional control valve, includes a molded part made from an elastomeric material in which at least one line section is formed. The line section connects at least two connections to one another, between which at least one flow path extends. The device or valve has a control unit that includes an actuator coupled to at least one blocking element. The at least one blocking element is displaced by the actuator between a blocking position and a release position. In the blocking position, the at least one blocking element deforms the at least one line section in order to block the at least one flow path.
Claims17
A device for controlling fluid media, comprising:
- a molded part made from an elastomeric material and including three connections, between which three connections first and second flow paths extend;
- a control unit, which includes an actuator;
- and
- first and second blocking element;
- wherein first and second line sections, which each connect two of the three connections to one another, are formed in the molded part;
- wherein each of the first and second flow paths extends between two of the three connections;
- wherein the actuator is coupled to the first and second blocking elements via a coupling mechanism and displaces each of the first and second blocking elements between a blocking position and a release position, to selectively block or release each of the first and second flow paths, respectively;
- and
- wherein the first and second blocking elements, in the blocking position, deform the respective first and second line sections to block the respective first and second flow paths;
- wherein the coupling mechanism is driven by the actuator and mechanically couples the first blocking element and the second blocking element to one another;
- wherein the first blocking element is in the blocking position when the second blocking element is in the release position;
- wherein the first blocking element is in the release position when the second blocking element is in the blocking position;
- wherein the coupling mechanism is designed as a scissor mechanism;
- and
- wherein the first blocking element is assigned to a first scissor lever of the scissor mechanism and the second blocking element is assigned to a second scissor lever of the scissor mechanism.
