Abstract
A jet reflector servovalve includes a flexure tube and reflector that opposes a fluid nozzle and fluid receivers of the servovalve. During operation, the nozzle directs a pressurized fluid jet toward the reflector. The pressurized fluid travels within a second stage of the servovalve, toward the reflector. The reflector directs or reflects the fluid back toward the fluid receivers to adjust a position of a spool of the servovalve. The configuration of the reflector, the nozzle, and the receivers allows transmission of the pressurized fluid within the second stage of the servovalve and minimizes the necessity for multiple o-rings between the second stage of the servovalve and a torque motor of the servovalve, thereby reducing manufacturing costs of the servovalve.
