Nozzle with locking nut

A method for locking a nozzle in position within a body of a servovalve, said body having a cylindrical bore defining an inner surface, said method comprising:

• positioning said nozzle within said cylindrical bore of said body of said servovalve, said nozzle having a tubular shape extending between a first end and a second end with an outer cylindrical surface and an inner surface said inner surface comprising a thread;
• providing a locking member within said nozzle, said locking member comprising an outer circumferential surface having a thread that corresponds to the thread of the inner surface of the nozzle;
• and
• providing torque to said locking member to screw said locking member into and within said nozzle axially in a direction of the nozzle second end via said threaded surfaces and to radially expand said outer cylindrical surface of the nozzle into a press-fit arrangement with the inner surface of said cylindrical bore of said body of said servovalve;
• wherein said first end of said nozzle is configured to receive said locking member;
• and
• wherein said nozzle comprises a first portion extending from said first end and in the direction of said second end, said first portion comprising a plurality of cut-out sections provided around its circumference with wall sections provided between said cut-out sections, said cut-out sections extending from said first end of the nozzle in the direction of the second end of the nozzle, said nozzle further comprises a second portion extending from said first portion in the direction of the nozzle second end, wherein said second portion comprises a solid tubular shape with a circumferentially extending wall to result in a press-fit seal between the external surface of the nozzle and the inner surface of cylindrical bore of said body of said servovalve.
