Abstract

An oil control module for a gas turbine engine is provided comprising a housing on which numerous components of a lubricating system are mounted. The components may include a variable oil reduction valve/shuttle valve, a main oil pressure sensor, a main oil temperature sensor, a main oil filter delta pressure sensor, an oil debris monitor, a lube filter, an active oil damper valve, a cool oil orifice, a knock down orifice and a lube trim orifice. By packing numerous lubricating system components onto or within a housing located adjacent to the gas turbine engine, the oil control module reduces cost and weight and simplifies the maintenance of the lubricating system.

Claims

1. An oil control module comprising:

a housing;

one or more oil processing components hard mounted to the housing, the housing having an exterior and defining an interior;

a lube filter located within the housing interior; and

one or more removable plug-like devices defining orifices located within the housing interior and configured to passively regulate a flow of oil in circuits located within the oil control module.

2. The oil control module of claim 1 wherein the one or more oil processing components includes:

a variable oil reduction valve/shuttle valve;

a main oil pressure sensor;

a main oil temperature sensor;

a main oil filter delta pressure sensor; and

an oil debris monitor.

3. The oil control module of claim 2 wherein the one or more oil processing components are hard mounted to the exterior of the housing.

4. The oil control module of claim 3 wherein the one or more plug-like devices includes:

a cool oil orifice;

a knock down orifice; and

a lube trim orifice.

5. The oil control module of claim 4 wherein the one or more plug-like devices are configured such that they can be changed out.

6. The oil control module of claim 5 further comprising:

a lube filter removably located within the housing interior, the housing configured such that the lube filter can be removed out.

7. The oil control module of claim 6 further comprising:

a plurality of oil tubes running into and out of the housing for accommodating fluid flow.

8. The oil control module of claim 7 wherein the plurality of oil tubes includes:

a plurality of lube in lines; and

a plurality of lube out lines.

9. The oil control module of claim 8 further comprising:

an active oil damper valve located in fluid communication with one of the lube out lines.

10. The oil control module of claim 9 wherein:

the active oil damper valve is hard mounted to the outside of the housing.

11. The oil control module of claim 10 further comprising:

a vent line running from the variable oil reduction valve/shuttle valve and tied into the active oil damper valve.

12. An oil control module comprising:

a housing on which are mounted multiple lubricating components, the housing defining an interior;

a lube filter located within the housing interior; and

one or more internally manifolded systems that permit a functional interconnection between two or more of the lubricating components, the multiple lubricating components including one or more removable plug-like devices defining orifices located within the interior of the housing and configured to passively regulate a flow of oil in circuits located within the oil control module.

13. The oil control module of claim 12 wherein the multiple lubricating components comprise:

a variable oil reduction valve/shuttle valve;

a main oil pressure sensor;

a main oil temperature sensor;

a main oil filter delta pressure sensor; and

an oil debris monitor.

14. The oil control module of the claim 13 wherein the multiple lubricating components further comprise:

an active oil damper valve; and

wherein the orifices of the one or more removable plug-like devices are one of;

a cool oil orifice;

a knock down orifice; and

a lube trim orifice.

15. The oil control module of the claim 13 further comprising:

electrical interfaces and plumbing interfaces extending from the housing.

16. The oil control module of claim 15 wherein:

the housing is configured to mount to a gas turbine engine in a location close to and exterior of the gas turbine engine.

17. The oil control module of claim 16 wherein:

the gas turbine engine comprises a fan section, a compressor section, a combustor section and a turbine section; and

the housing is configured to mount aft of the compressor section and forward the turbine section.
