A pump device, in particular for a brake system of a motor vehicle, includes two hydraulic chambers, a linear drive, and a pump piston. Each of the chambers has at least two fluid connections. The pump piston interacts with the chambers. The linear drive is embodied as a reluctance drive and includes a longitudinally movable armature, a housing-fastened stator that is configured to receive current, and at least one spring element. The at least one spring element is associated with the armature, and is configured to counteract a drive force of the reluctance drive. The armature is connected to the pump piston.

A fuel injector for fuel injection systems of internal combustion engines has an excitable actuator for activating a valve closing element, which forms a sealing seat together with a valve face implemented on a valve seat element. Multiple spray-discharge openings are implemented in the valve seat element downstream from the valve face. The fuel injector is distinguished in that the spray-discharge openings include at least one upstream first spray-discharge opening section and one downstream second spray-discharge opening section having a different opening width and a wall area of the second spray-discharge opening section of all spray-discharge openings on a semi-circle runs either parallel or at a right angle to the longitudinal axis of the valve seat element having the spray-discharge openings. The valve seat element is manufactured using metal injection molding methods.
