Claims9
An actuator for converting rotary to linear motion, the actuator comprising a drive shaft mounted in a housing for rotation about an axis;
- a first ride plate mounted on the drive shaft to rotate with the drive shaft, the first ride plate being mounted at an adjustable angle between the first ride plate and the drive shaft;
- a reciprocating output element mounted on the housing and the reciprocating output element being coupled to the first ride plate;
- the reciprocating output element extending from the first ride plate in a direction substantially perpendicular to a direction of the linear motion;
- the reciprocating output element extending beyond an exterior circumference of the first ride plate;
- and
- the adjustable angle between the first ride plate and the drive shaft being adjustable by an adjustment member, that comprises a rod mounted to rotate with the drive shaft, the rod being movable axially in a direction parallel to the axis of the drive shaft, the rod being coupled to the first ride plate.
