摘要： A nozzle assembly (N) comprises a nozzle (10) received in a nozzle receiving bore (8c) of a nozzle housing (8). The nozzle receiving bore (8c) has a longitudinal axis (X-X). The nozzle housing (8) further comprises a locking pin receiving bore (30) having a longitudinal axis (Y-Y) that is perpendicular to the nozzle housing axis (X-X). The locking pin receiving bore (30) intersects the nozzle receiving bore (8c), whereby an aperture (34) is formed between the locking pin receiving bore (30) and the nozzle receiving bore (8c). A locking pin (20) is received in the locking pin receiving bore (30), a portion of the locking pin (20) protruding through the aperture (34) and into the nozzle receiving bore (8c) so as to engage a circumferential portion (36) of the nozzle (10).

摘要： A nozzle (26) of or for a servo valve comprises a nozzle element (30) having a fluid outlet (32) at a first axial end (34) and a tubular body (36) extending from the first end (32) to an opposed, second axial end (38). The nozzle (26) further comprises a plug element (40) mounted in and closing the second axial end (38) of the tubular body (36), thereby defining an internal cavity (42) within the tubular body (36). One or more openings (44) are formed through the tubular body (36) to fluidly communicate with the internal cavity (42). A filter (62) may be mounted across the internal cavity (42) at a position axially intermediate the openings (44) and the fluid outlet (32).
