Abstract:
A servovalve includes a fluid transfer valve assembly comprising a supply port and a control port; a moveable valve spool arranged to regulate flow of fluid from the supply port to the control port in response to a control signal; and a drive assembly configured to axially move the valve spool relative to the fluid transfer assembly in response to the control signal to regulate the fluid flow. The drive assembly comprises a steerable jet pipe moveable by an amount determined by the control signal to cause corresponding movement of the valve spool and the jet pipe terminates at one end in a nozzle and at the other end being in fluid flow engagement with a fluid supply pipe. Movement of the valve spool is caused by fluid flowing from the nozzle to engage with the valve spool.

Claim (Index 1):
A servovalve comprising:\n a fluid transfer valve assembly comprising a supply port and a control port; a moveable valve spool arranged to regulate flow of fluid from the supply port to the control port in response to a control signal; and a drive assembly configured to axially move the valve spool relative to the fluid transfer assembly in response to the control signal to regulate the fluid flow; wherein the drive assembly comprises a steerable jet pipe moveable by an amount determined by the control signal to cause corresponding movement of the valve spool; the jet pipe terminating at one end in a nozzle and at the other end being in fluid flow engagement with a fluid supply pipe, whereby movement of the valve spool is caused by fluid flowing from the nozzle to engage with the valve spool, and wherein the end of the supply pipe furthest from the jet pipe is attached to a slider component for sliding movement responsive to movement of the jet pipe responsive to the control signal.
