The invention relates to 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) as well as at least one valve opening (18, 19), located between the two and surrounded by a valve seat (21, 22); h
The invention relates to 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) as well as at least one valve opening (18, 19), located between the two 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 valve closing spring. For creating a robust device with a long service life, and in which the valve member actuating device (14) is hermetically separated from the medium, the valve member (23) has a closing body (24), cooperating with the at least one valve seat (21, 22), and a frame (25), separated from the medium, for engaging the valve member actuating device (14), which frame surrounds the closing body (24) and is solidly joined to it.

1. 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). 2. The device as defined by claim 1, wherein the closing body (24) is located in a valve chamber (20), which is located downstream of the at least one valve opening (18, 19) and through which the medium flows, and the frame (25) is located in a hollow chamber (26) surrounding the valve chamber (20); and that the valve chamber (20) and the hollow chamber (26) are separated from one another by a closed-ringlike seal (27). 3. The device as defined by claim 1, wherein the closing body (24) has a support (28), which is rigidly connected to the frame (25) via ribs (30, 31), and a coating (29) sheathing the support (28), on which coating at least one sealing face (34, 35), transversely spaced apart from the ribs (30, 31) and cooperating with the at least one valve seated (21, 22), is embodied. 4. The device as defined by claim 3, wherein the ringlike seal (27) is fixed at the ribs (30, 31) in such a way that it is penetrated by the ribs (30, 31) transversely to its longitudinal direction; and that the penetration points form a pivot bearing for the valve member (23). 5. The device as defined by claim 3, wherein the seal (27) and/or the coating (29) is formed of plastic, rubber, an elastomer, or the like, for instance both comprising the same material. 6. The device as defined by claim 3, wherein in the valve housing (11), a further valve inlet (16) and a further valve opening (19), surrounded by a further valve seat (22), are present; and that on the coating (29) of the closing body (24), a sealing face (35) cooperating with the further valve seat (22) is embodied, which is located with transverse spacing from the ribs (30, 31) on the side of the closing body (24) facing away from the first sealing face (34). 7. The device as defined by claim 6, wherein the two valve seats (21, 22), located on both sides of the pivot bearing of the valve member (23) have different-sized vertical spacings from the pivot bearing; and that the one sealing face (34) has a parallel orientation, and the other sealing face (35) has an acute-angled orientation, corresponding to the pivot angle of the valve member (23), to the plane of the frame (25) and support (28), and the sealing face (35) having the acute-angled orientation cooperates with the valve seat (22) having the greater vertical spacing. 8. The device as defined by claim 6, wherein in the vicinity of each sealing face (34, 35) embodied on the closing body (24), there is a hole (32, 33) in the support (28) that is filled with material of the coating (29). 9. The device as defined by claim 3, wherein the frame (25) and the cross-shaped support (28) as well as the ribs (30, 31) joining the frame (25) and the support (28) to one another are produced as a one-piece stamped stamping from a metal sheet. 10. . The device as defined by claim 9, wherein the frame (25) is substantially elliptical and the support (28) is cross-shaped. 11. The device as defined by claim 3, wherein the ribs (30, 31) include two diametrically extending ribs. 12. The device as defined by claim 1, wherein the ringlike seal (27) is fastened between the upper and lower housing parts (12, 13) of the valve housing (11). 13. The device as defined by claim 1, wherein the valve chamber (20) and the hollow chamber (26) are each machined partly into the upper housing part (12) and partly into in the lower housing part (13), respectively. 14. The device as defined by claim 1, wherein the pressure fork (39) is inserted loosely into a face-end recess (40) in the drive member (38); and that a further pressure fork (41) with two tines (411) is guided axially displaceably in the upper housing part (12) of the valve housing (11) and is pressed with its tines (411), on the side of the pivot bearing of the valve member (23) facing away from the first pressure fork (39), at opposed points (252) of the frame (25) by a compression spring (43); and that the spring force of the compression spring (43) is less than the spring force of the valve closing spring (36). 15. The device as defined by claim 14, wherein the engagement points (252) of the tines (411) of the further pressure fork (41) are diametrically opposite one another on the frame (25) at the further valve opening (19). 16.
