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.

First claim

What is claimed is:

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.
