Hochdynamische Servo-Ventilsteuervorrichtung

摘要

The sleeve (3) has valve control edges (5) connecting ducts (14) with those of the slider (4) and is axially moveable in a housing (2) by the action of a piezoelectric generator (11) and return spring (20) as the slider is moved by pressure through ducts (12). Absolute Hall effect (9) and relative eddy current (7) sensors establish the exact position (6) of the slider relative to the sleeve and the sleeve (8) to the housing.
