Abstract (en)
[origin: US6454239B1] A valve for controlling fluids, having a valve member (2), which is axially displaceable in a bore (7) of a valve body (6) and on one end has a valve closing member (8) that cooperates with a seat (9, 10), provided on the valve body (6), for opening and closing the valve (1); having a piezoelectric unit (3) for actuating the valve member (2); and having a tolerance compensating element (22) for compensating for elongation tolerances of the piezoelectric unit (3). The deflection of the piezoelectric unit (3) can be transmitted to the valve member (2) via a deflection element (20), and the piezoelectric unit (3) is disposed with its piezoelectric head (17) toward the valve member in the direction of motion of the valve member (2) essentially inside a length of the deflection element (20) and is connected to the deflection element via the tolerance compensating element (22). The latter is disposed parallel to the piezoelectric unit (3) and has virtually the same tolerance-dictated length-changing behavior as the piezoelectric unit (Drawing).
