Abstract:
A servovalve includes a single motor which actuates separate valve members of separate servovalve assemblies. Each of the valve members controls the flow of hydraulic fluid from separate hydraulic fluid sources. In order to provide each valve member with the ability to operate in the event that the other valve member becomes inoperable, such as caused by jamming of the valve member, each servovalve assembly includes a compression assembly that provides each servovalve assembly with a jam-override capability.
