Abstract
A nozzle assembly (N) comprises a nozzle received in a nozzle receiving bore of a nozzle housing. The nozzle receiving bore has a longitudinal axis (X-X). The nozzle housing further comprises a locking pin receiving bore having a longitudinal axis (Y-Y) that is perpendicular to the nozzle housing axis (X-X). The locking pin receiving bore intersects the nozzle receiving bore, whereby an aperture is formed between the locking pin receiving bore and the nozzle receiving bore. A locking pin is received in the locking pin receiving bore, a portion of the locking pin protruding through the aperture and into the nozzle receiving bore so as to engage a circumferential portion of the nozzle.
Claims17
A nozzle assembly (N) comprising:
- a nozzle;
- a nozzle housing having a nozzle receiving bore having a longitudinal axis (X-X), the nozzle being received within the nozzle receiving bore;
- a locking pin receiving bore having a longitudinal axis (Y-Y) that is perpendicular to the nozzle housing axis (X-X), the locking pin receiving bore intersecting the nozzle receiving bore, whereby an aperture is formed between the locking pin receiving bore and the nozzle receiving bore;
- a locking pin received in the locking pin receiving bore, a portion of the locking pin protruding through the aperture and into the nozzle receiving bore so as to engage and interfere with a circumferential portion of the nozzle.
A method of assembling a nozzle assembly comprising:
- providing a nozzle housing having a nozzle receiving bore having a longitudinal axis (X-X) and a locking pin receiving bore having a longitudinal axis (Y-Y) perpendicular to the longitudinal axis (X-X) of the nozzle receiving bore and intersecting the nozzle receiving bore, whereby an aperture is formed between the locking pin receiving bore and the nozzle receiving bore;
- inserting a nozzle into the nozzle receiving bore;
- and
- inserting a locking pin into the locking pin receiving bore such that a portion of the locking pin protrudes through the aperture and presses onto a circumferential portion of the nozzle to lock the nozzle in position within the nozzle receiving bore.
A method of calibrating a nozzle assembly which comprises a nozzle housing having a nozzle receiving bore having a longitudinal axis X-X and a locking pin receiving bore having an axis (Y-Y) perpendicular to the axis (X-X) of the nozzle receiving bore and intersecting the nozzle receiving bore, whereby an aperture is formed between the locking pin receiving bore and the nozzle receiving bore;
- the method comprising:
- moving a nozzle in the nozzle receiving bore to a desired axial position within the nozzle receiving bore;
- and
- inserting a locking pin into the locking pin receiving bore such that a portion of the locking pin protrudes through the aperture and presses onto a circumferential portion of the nozzle to lock the nozzle in the desired axial position within the nozzle receiving bore.
