摘要： A servovalve comprising: a fluid transfer valve assembly 5 comprising a supply port 14 and a control port 15; a moveable valve spool 4 arranged to regulate flow of fluid from the supply port 14 to the control port 15 in response to a control signal; and a drive member 3 configured to axially move the valve spool 4 relative to the fluid transfer assembly 5 in response to the control signal to regulate the fluid flow;
wherein the valve spool 4 comprises a tubular member defining a conduit for fluid from the supply port 14 and an opening 18 in fluid flow alignment with the supply port 14 such that fluid flows from the supply port into the tubular member conduit; the valve spool 4 further comprising an aperture 19 via which fluid flows out from the conduit; and wherein the valve spool 4 is axially moveable between an open position in which a fluid flow path is formed between the aperture 19 and the control port 15 and a closed position in which fluid is blocked from flowing between the aperture and the control port.

摘要： The present disclosure relates to a servovalve assembly (10) comprising a pair of opposed nozzles (12a, 12b) spaced apart by a first gap (G). A control element (16) positioned in the first gap (G) between the pair of opposed nozzles (12a, 12b). Each nozzle (12a, 12b) has an outlet opening (13a, 13b). The control element (16) has a central control portion (16a) and two resiliently deformable end portions (16b, 16c) at opposite ends of the central control portion (16a). The central control portion (16a) is perpendicular to a central axis (C) of each nozzle outlet opening (13a, 13b). The control element (16) is configured such that the two resiliently deformable end portions (16b, 16c) elastically deform when the control element (16) is placed under tension by a force applied parallel to the central control portion (16a), so as to move the control element (16) in a direction parallel to the central axis (C) of each nozzle outlet opening (13a, 13b).
