Abstract: An injection nozzle (30) for a compression-ignition internal combustion engine, the injection nozzle (30) comprising: a nozzle body (32) provided with a bore (35) within which a valve needle (34) is movable along a primary valve needle axis (A-A), the valve needle (34) being engageable with a valve seating (38) defined by the bore (35) to control fuel delivery through a nozzle outlet; the bore (35) comprising first and second regions (36, 37), the second bore region (37) having a smaller diameter than the first bore region (36), and a transition (48) between the first and second bore regions (36, 37); the valve needle (34) including a guide region (44) for guiding the movement of the valve needle (34) within the nozzle body (32), the guide region (44) comprising a shoulder portion (54) and a relieved region disposed downstream of the shoulder portion (54); the relieved region comprising a first flat portion (46a) and a first tapered portion (52a), disposed between the first flat portion (46a) and the shoulder portion (54), wherein the radius of the valve needle (34) increases across the first tapered portion (50a) in the upstream direction; and wherein, when the valve needle (34) is in a zero lift state, the shoulder portion (54) is disposed adjacent to the transition (48) so as to define a restriction therebetween for restricting the flow of fuel therethrough, and the overlap between the shoulder portion (54) and the transition (48) in the direction of the primary valve needle axis (A-A) is less than the height of the full lift of the valve needle (34).

Abstract: The invention relates to a circuit breaker (1) comprising a fixed contact (13) that is connected to a first switch terminal (14), and a moving contact (12) which is mechanically coupled to an armature (9) by means of a switching mechanism (7) and is electrically connected to a coil (2) that actuates the armature (9) and is connected to a second switch terminal (10). A magnetic field-sensitive sensor (3) is provided for detecting the coil current (IL). Said sensor (3) is connected to a control device (4) in order to compare the sensor signal (SI) with a stored characteristic tripping curve (K) and generate a control signal (SA) for actuating the switching mechanism (7) when said characteristic tripping curve (K) is exceeded.
