    Abstract: An armature (132; 232; 332) for a solenoid actuator is disclosed. The armature comprises a first face (170; 270; 370) comprising a recess (174; 274; 374) suitable for receiving a biasing spring in use of the armature; a second face (172; 272; 372) opposite the first face (170; 270; 370); and fluid communication means (178; 210; 310) for providing a fluid flow path through the armature between the recess (174; 274; 374) and the second face (172; 272; 372) in use of the armature. The first face (170; 270; 370) is uninterrupted by the fluid communication means (178; 210; 310). The invention reduces the risk of cavitation damage during operation of the actuator. In one application, the actuator is used in a fluid pump (100; 200) for a selective catalytic reduction system.

    Abstract: An injection device for administering a reagent into an exhaust passage of an internal combustion engine, the injection device having an axis (A) along its length and comprising an outwardly opening valve member (14) having a seating surface which is engageable with a valve seating region (30). A seating member provided with an internal bore (12) which defines the valve seating region (30), wherein the internal bore (12) further defines a flow re-directing region (32) downstream of the valve seating region (30). The seating member (10) has an end face (36; 136) provided with a feature (38; 138; 238; 338; 438; 538) which intersects with at least a portion of the flow re-directing region (32) to define, together with the flow re-directing region (32), a spray path for reagent exiting the injection device when the valve member (10) is moved outwardly from the bore (12) away from the valve seating region (30). The spray path has a variable spray angle, relative to the axis A, around the circumference of the valve seating region (30).
