Abstract

A valve for injecting fuel has a valve body (4), in which a recess is embodied. The recess widens in a downstream side region (11) to a separation edge. The valve further comprises a valve needle which is arranged in the recess and has a closing element (14). In a closed position the closing element (14) seats on a valve seat (18) and blocks or else releases the flow. The closing element (14) is embodied such that a gap (19) is embodied between the valve body (4) and the closing element (14) downstream of the valve body (4), the gap comprising a gap angle (.beta.), a gap length (l) and a maximum gap width (s). The gap angle (.beta.) and the gap length (1) are embodied such that in the closed position, the maximum gap width (s) is at least as large as a surface roughness of the valve body (4) or of the closing element (14) and that the maximum gap width (s) amounts to a maximum of 10 micrometers.
