The invention relates to an injector (1) for injecting fuel into a combustion chamber of an internal combustion engine, wherein an injection member (10), which releases or closes at least one injection opening (20), is actuated by a control valve (29), wherein the control valve (29) releases or closes a connection (43) from a control space (24) to a fuel return (8) in that a closing member (30) arranged in operational connection to a pressure spring (36) is placed in a seat (34) or releases said seat, and wherein a pin-like element (35), which in the region protruding from the closing member (30) is radially surrounded by the pressure spring (36) and on the side opposite the seat (34) is supported against a stationary support element (37) together with the pressure spring (36), is arranged axially movably in the closing member (30). According to the invention, the closing member (30) is arranged with radial play in relation to a valve piece (16), and the pin-like element (35) has an enlarged radial distance (R) to the pressure spring (36) at least in the contact region with the support element (37). |
