Abstract (en)
[origin: US6899069B2] A valve for controlling fluids, in particular in an injection valve of an internal combustion engine, including a valve housing ( 20 ), in which housing a system region ( 21 ) is embodied, in which region a piezoelectric actuator module ( 22 ) and a hydraulic coupler module ( 23 ) are disposed, which has both an adjusting piston ( 24 ), on which the actuator module ( 22 ) acts, and an actuating piston ( 30 ) that is operatively connected via a hydraulic chamber ( 29 ) to the adjusting piston ( 24 ) and that is connected to a valve closing member ( 31 ) cooperating with a valve seat ( 37 ), and the adjusting piston ( 24 ) and the actuating piston ( 30 ) define the hydraulic chamber ( 29 ), and a system pressure for refilling the hydraulic chamber ( 29 ) prevails in the system region ( 21 ), from which a diversion conduit ( 38 ) branches off. The system region ( 21 ) is acted upon by a fluid via the diversion conduit ( 38 ).
