Abstract
A jet for treating a yarn with a fluid has a flow control plate having a first and a second flow control opening. The flow control openings are located in the plate such that when the plate is mounted between the jet body and the manifold body, at least one, but preferably both, of the flow control openings in the plate at least partially overlap the inlet end of one (or both) of the fluid supply channels, thereby to modify the fluid flow area presented to the manifold by the fluid supply channel(s).
Claims8
In a jet for treating a yarn with a pressurized fluid, the jet having:
- a jet body having a first and a second surface thereon, at least one yarn passage formed in the first surface of the body,
- a first and a second fluid conduit formed in the first surface of the jet body, each fluid conduit intersecting the yarn passage for conducting a treatment fluid thereto,
- a first and a second fluid supply channel extending through the jet body from the first to the second surface, each fluid supply channel having an inlet end and an outlet end, the outlet end of each fluid supply channel being in fluid communication with a respective one of the fluid supply conduits, the inlet end of each fluid supply channel having a predetermined fluid flow area associated therewith, and
- a manifold body having a fluid supply manifold therein, the inlet end of each of the first and the second fluid supply channels being in fluid communication with the supply manifold, the improvement comprising:
- a plate having a first and a second flow control opening therein, the flow control openings being located in the plate such that when the plate is mounted between the jet body and the manifold body at least one opening in the plate at least partially overlaps the inlet end of one of the fluid supply channels to modify the fluid flow area presented to the manifold by that fluid supply channel.

In a jet for treating a yarn with a pressurized fluid, the jet having:
- a jet body having a first and a second surface thereon, at least one yarn passage formed in the first surface of the body,
- a first and a second fluid conduit formed in the first surface of the jet body, each fluid conduit intersecting the yarn passage for conducting a treatment fluid thereto,
- a first and a second fluid supply channel extending through the jet body from the first to the second surface, each fluid supply channel having an inlet end and an outlet end and having an axis therethrough, the outlet end of each fluid supply channel being in fluid communication with a respective one of the fluid supply conduits, the inlet end of each fluid supply channel having a predetermined fluid flow area associated therewith, and
- a manifold body having a fluid supply manifold therein, the inlet end of each of the first and the second fluid supply channels being in fluid communication with the supply manifold, the improvement comprising:
- a plate having a first and a second flow control opening therein, each flow control opening having an axis, the flow control openings being located in the plate such that when the plate is mounted between the jet body and the manifold body each of the openings in the plate register with the inlet end of one of the fluid supply conduits such that the axis of each opening is collinear with the axis of the supply channel with which it is registered, the first opening having a fluid flow area that is smaller than the fluid flow area presented to the manifold by the fluid supply channel with which it is registered.
