Abstract

A fluid distribution assembly for distributing a fluid, the fluid distribution assembly includes an inlet housing including a first conduit and a bypass conduit; a chip detector cavity in fluid communication with the first conduit such that the fluid can pass through the first conduit into the chip detector cavity; and an outlet housing in fluid communication with the chip detector cavity and the bypass conduit such that the fluid can pass into the outlet housing through the chip detector cavity and/or the bypass conduit.

First claim

What is claimed is:

1. A fluid distribution assembly for distributing a fluid, the fluid distribution assembly comprising:
an inlet housing including a first conduit and a bypass conduit including an inlet portion and an outlet portion;
a chip detector cavity in fluid communication with the first conduit such that the fluid can pass through the first conduit into the chip detector cavity;
a screen provided at one of the inlet portion and the outlet portion of the bypass conduit; and
an outlet housing in fluid communication with the chip detector cavity and the bypass conduit such that the fluid can pass into the outlet housing through the chip detector cavity and through the screen into the bypass conduit in a first direction and fluid may pass in a second, opposing direction from the outlet housing through the bypass conduit back through the screen.

2. The fluid distribution assembly of claim 1 further comprising:
a screen positioned between the first conduit and the bypass conduit, the screen to pass fluid between the first conduit and the bypass conduit.

3. The fluid distribution assembly according to claim 1 further comprising:
a filter in the chip detector cavity between the first conduit and the outlet housing.

4. The fluid distribution assembly according to claim 1 wherein:
when fluid flow through the first conduit and the chip detector cavity is unblocked, fluid flows in the first conduit, the chip detector cavity and the bypass conduit to the outlet housing.

5. The fluid distribution assembly according to claim 1 wherein:
when fluid flow through the first conduit or the chip detector cavity is blocked, fluid flows in the bypass conduit to the outlet housing.

6. The fluid distribution assembly according to claim 1 wherein: the inlet housing includes an inlet;
the inlet housing including a vortex reducer located adjacent the inlet which can reduce vortices created at an opening between the first conduit and the bypass conduit.

7. The fluid distribution assembly of claim 6 wherein:
the vortex reducer includes a lip extending from one wall of the inlet housing towards the inlet.

8. A rotary wing aircraft comprising: a rotor;
a gearbox coupled to the rotor;
an engine coupled to the gearbox; and
a lubricant distribution system providing lubricant from a sump to the gearbox, the lubricant distribution system including:
an inlet housing including a first conduit and a bypass conduit including an inlet portion and an outlet portion;
a chip detector cavity in fluid communication with the first conduit such that the fluid can pass through the first conduit into the chip detector cavity, the chip detector cavity housing a chip detector;
a screen provided at one of the inlet portion and the outlet portion of the bypass conduit; and
an outlet housing in fluid communication with the chip detector cavity and the bypass conduit such that the fluid can pass into the outlet housing through the chip detector cavity and through the screen into the bypass conduit in a first direction and fluid may pass in a second, opposing direction from the outlet housing through the bypass conduit back through the screen.

9. The rotary wing aircraft of claim 8 further comprising:
a screen positioned between the first conduit and the bypass conduit, the screen passing fluid between the first conduit and the bypass conduit.

10. The rotary wing aircraft according to claim 8 further comprising:
a filter in the chip detector cavity between the first conduit and the outlet housing.

11. The rotary wing aircraft according to claim 8 wherein:
when fluid flow through the first conduit is unblocked, fluid flows in the first conduit and the bypass conduit to the outlet housing.

12. The rotary wing aircraft according to claim 8 wherein:
when fluid flow through the first conduit is blocked, fluid flows in the bypass conduit to the outlet housing.

13. The rotary wing aircraft according to claim 8 wherein: the inlet housing includes an inlet;
the inlet housing including a vortex reducer located adjacent the inlet.

14. The rotary wing aircraft of claim 13 wherein:
the vortex reducer includes a lip extending from one wall of the inlet housing towards the inlet.

15. The rotary wing aircraft according to claim 8 further comprising:
a pump coupled to the outlet housing, the pump directing lubricant through inlet housing.
