Abstract
A servo valve includes first and second nozzles spaced apart from each other, an elongate control member positioned between the nozzles, and a solenoid assembly surrounding at least a portion of the control member. The elongate control member has a first end and an opposing second end. The control member is configured to translate in response to the solenoid assembly being energised, such that the first end is moved towards the first nozzle and the second end is moved away from the second nozzle or the first end is moved away from the first nozzle and the second end is moved towards the second nozzle.
Claims15
A servo valve comprising:
- first and second nozzles spaced apart from each other;
- an elongate control member for controlling fluid flow through the first and second nozzles, the control member being positioned between the nozzles and having a first end and an opposing second end;
- and
- a solenoid assembly surrounding at least a portion of the control member, and configured to translate the control member in response to the solenoid assembly being energised, such that the first end is moved towards the first nozzle and the second end is moved away from the second nozzle.
A method of controlling a servo valve comprising first and second nozzles in fluid communication with first and second portions of a spool, the method comprising:
- controlling fluid flow through first and second nozzles by translating an elongate control member between the first and second opposed nozzles, wherein the step of translating the control member comprises energising a solenoid assembly in operative connection with the control member.
