Patent ID: 8104510

Claim:
A device for regulating the flow of a liquid or gaseous medium, having a valve housing ( 11 ), which has at least one valve inlet ( 15 , 16 ) and a valve outlet ( 17 ) and at least one valve opening ( 18 , 19 ), located between the at least one valve inlet ( 15 , 16 ) and the valve outlet ( 17 ) and surrounded by a valve seat ( 21 , 22 ), having a valve member ( 23 ) controlling the valve opening ( 18 , 19 ), and having a valve member actuating device ( 14 ), which has a valve closing spring ( 36 ) and an actuator ( 37 ) operating counter to the restoring force of the valve closing spring ( 36 ), wherein the valve member ( 23 ) has a closing body ( 24 ), cooperating with the at least one valve seat ( 21 , 22 ), and a frame ( 25 ), which is separated from the medium and which surrounds the closing body ( 24 ) and is solidly connected to it; and that the valve member actuating device ( 14 ) engages the frame ( 25 ), wherein the valve housing ( 11 ) is composed of a lower housing part ( 13 ), through which the medium flows, and an upper housing part ( 12 ), at least partly receiving the valve member actuating device ( 14 ); wherein the valve chamber ( 20 ) that receives the closing body ( 24 ), the hollow chamber ( 26 ) that receives the frame ( 25 ), and the ringlike seal ( 27 ) between the valve chamber ( 20 ) and the hollow chamber ( 26 ) are located at the interface of the two housing parts ( 12 , 13 ); and wherein the actuator ( 37 ) has a drive member ( 38 ), which is displaceable counter to the force of the valve closing spring ( 36 ); wherein a pressure fork ( 39 ) with two tines ( 391 ) is located on the face end of the drive member ( 38 ); and wherein the two tines ( 391 ), as a result of the spring force of the valve closing spring ( 36 ) engaging the drive member ( 38 ), rest on two points ( 251 ) of the frame ( 25 ) that are diametrically opposite one another at the at least one valve opening ( 18 ).
