Claims17
A spacer for a fluid nozzle, comprising:
- a body configured to fit within a sheath of the fluid nozzle such that a fluid tube positioned within the sheath is held bent over its longitudinal dimension by the body thereby altering a natural frequency of the fuel tube compared to if the fuel tube were not held bent;
- and
- an off-center hole defined through the body at least in an orthogonal direction to a plane that is coplanar with the body, wherein the off-center hole is configured to receive a fluid tube within the sheath of the fluid nozzle to bend the fluid tube within the sheath, wherein the off-center hole is closer to a center of the body than a radially outer diameter of the body.
A fluid nozzle, comprising:
- a sheath;
- a nozzle base;
- a nozzle tip;
- a fluid tube configured to be contained within the sheath and supported at the nozzle base and the nozzle tip;
- and
- at least one spacer disposed within the sheath such the fluid tube is held bent over its longitudinal dimension thereby altering a natural frequency of the fuel tube compared to if the fuel tube were not held bent, the spacer further comprising:
- a body configured to fit within the sheath of the fluid nozzle;
- and
- an off-center hole defined through the body at least in an orthogonal direction to a plane that is coplanar with the body, wherein the off-center hole is configured to receive the fluid tube within the sheath of the fluid nozzle to bend the fluid tube within the sheath, wherein the off-center hole is closer to a center of the body than a radially outer diameter of the body.
