摘要
A flapper (114) for use in a servovalve is described, the flapper (114) comprising a first material (215) and a second material (216), the first material (215) having a first coefficient of thermal expansion and the second material (216) having a second coefficient of thermal expansion and wherein the first and second coefficients of thermal expansion are different to each other. An armature/flapper assembly is also described, which comprises this flapper (114) as well as a plate (119) and a torsion bridge (111). A method of compensating for alteration of the null of a servovalve due to temperature changes in a servovalve is also described.
