Abstract
A valve () comprising a motor () having an output shaft () orientated about a motor axis (), a hydraulic valve having a drive spool () configured to move from a first position to a second position, a mechanical linkage () between the output shaft () and the drive spool () having a sleeve () mechanically coupled to the output shaft (), a pole shaft () configured for sliding engagement in a direction generally perpendicular to the motor axis, a link () connected to the pole shaft () by a pivot joint (), a drive shaft () coupled to the link () and rotatable about a drive axis, the drive shaft () having an end portion to engage and apply a force to the spool (), and a spring () to provide a bias between the pole shaft () and the sleeve (), such that a distance between the motor axis and the pivot joint multiplied by a distance between the drive axis and the applied force is less than a distance between the drive axis and the pivot joint.
