Abstract
A servo piston assembly having a servo piston body mounted within a servo piston cylinder. A pair of bushings are mounted within each end of the servo piston body. An elongated bore extends through the servo piston body and receives a guide rod that extends out of the servo piston body and is received within the servo piston cylinder.
Claims5
A servo piston assembly, comprising:
- a transverse axis servo piston mounted within a servo piston cylinder;
- a pair of bushings connected within each end of the servo piston;
- a bore that extends through the servo piston;
- a guide rod that is received within the bore and extends beyond the servo piston and is fully contained within the servo piston cylinder;
- wherein the guide rod includes a pair of rods cantilevered from within the servo piston cylinder;
- and
- wherein during operation a tipping moment is induced on the servo piston due to the distance between the piston and a swashplate connection point and a translation axis of the piston.
