Abstract (en)
[origin: DE10057631A1] The fuel injection valve (1) comprises a first valve pin (3) that stands in working connection with a first valve lock body (4). The first valve lock body operates with a first valve seat surface (5) in a valve seat body (6) together with a seal seat (7). The fuel injection valve has, downstream of the seal seat, an inject-out opening (8). Upstream of the seal seat, in the supply of the fuel, is a twist element (28) that has a twist channel (34) and a control twist channel (30) and which sits in a twist chamber (35). There is a second valve pin (20) that covers over the control supply opening (29) to the control twist channels. The second valve pin may be built as a hollow pin (21) and enclose, coaxially, the first valve pin.
