摘要： A valve for metering fluid under pressure includes: a valve housing which has an inlet opening and a metering opening as well as a valve seat enclosing the metering opening having an outwardly pointing seat surface; a valve needle carrying a closing head; a valve-closing spring acting on the valve needle and applying the closing head to the valve seat; and an electrical actuator, which applies a compressive force to the valve needle, lifting the closing head outwardly away from the valve seat. To prevent transverse forces on the valve needle, which can cause a deflection of the valve needle, a gimbal-mounted spring disk, which is pushed onto the valve needle, is used as the valve-closing spring.

摘要： A fuel injection valve, in particular an injection valve for fuel injection systems of internal combustion engines, is made of a piezoelectric or magnetostrictive actuator and a valve closing body that can be set in motion by the actuator via a valve needle and that interacts with a valve seat surface to produce a seat. To compensate for the temperature expansion, at least one damping element made of a solid is present and exhibits an almost static behavior at a high deformation rate and is elastically or plastically deformable at a low deformation rate.

摘要： A directly actuated injection valve comprises a hollow valve housing, a valve member disposed within the hollow interior, a biasing mechanism, an actuator assembly and a hydraulic link assembly. The valve member is movable between a closed position and an open position for governing the flow of fuel into the combustion chamber of an internal combustion engine. The biasing mechanism, preferably a spring, biases the valve member in the closed position. The actuator assembly generates an opening force that acts against the valve spring to open the valve. The hydraulic link assembly is interposed between the valve member and the valve spring and the actuator assembly. The hydraulic link assembly transmits respective closing and opening forces to the valve member. The hydraulic link preferably comprises a piston disposed within a cylinder that is filled with a hydraulic fluid. The opening and closing forces are transmitted through a thickness of the hydraulic fluid that is trapped between the planar surfaces of the piston and the head and base of the hydraulic cylinder.

摘要： The present disclosure teaches a method for operating an injector with piezoelectric direct drive of an injection system of an internal combustion engine. The method may comprise providing a current to the piezoelectric actuator at a first level, then quickly reducing the current for charging the piezoelectric actuator before or after the opening of the nozzle needle and before the mechanical impacting of the needle or the hydraulic equilibrium point of the needle, the current reduced to such an extent that the sum of the forces acting on the nozzle needle become approximately zero in the case of a small needle lift (part lift), and after reducing the current, supplying a low current in a constant or ramp-shaped fashion until a predetermined setpoint energy is reached.
