摘要： A metering valve or an injector includes: a valve-seat member which closes a valve chamber and has a central valve opening, and a spray orifice disk downstream from the valve-seat member in the flow direction of the fluid, which has at least one spray orifice. The spray orifice disk has a swirl chamber concentric with the spray orifice and at least one swirl duct leading from the swirl chamber to beneath the valve opening, and the swirl chamber and swirl duct are integrally formed as recesses into the disk surface of the spray orifice disk facing the valve body. The swirl duct has a duct cross section and the spray orifice has an orifice cross section such that the ratio of the duct cross section to the orifice cross section is equal to or greater than 1.5.

摘要： A valve for atomizing fluid is specified, in particular an injection or metering valve for fuel injection or exhaust-gas systems of motor vehicles, which valve has a valve seat body (11) with a valve seat (14) which surrounds a valve opening (13), a perforated injection disc (17) which bears against the front side of the valve seat body (12) downstream of the valve opening (13) and has at least one spray hole (18) which is offset radially with respect to the valve opening (13), and an inflow cavity (19) which is present between the valve opening (13) and the at least one spray hole (18). For the inexpensive and reproducible production of a stable, corrosion-resistant perforated injection disc (18) with improved atomization of the ejected fluid, the inflow cavity (19) is formed by at least one depression (20) which is made in that disc face of the perforated injection disc (17) which faces the valve seat body (12), in such a way that part of the depression (20) protrudes into the valve opening (13) and the remaining part of the depression (20) is covered by the valve seat body (12). The at least one spray hole (18) is made in that part of the depression (20) which is covered by the valve seat body (12), close to the depression wall, which faces away from the valve opening (13), into the bottom (201) of the depression (20).
