Thin Film Coating For Fuel Injector Components

US Patent:
6715693, Apr 6, 2004
Filed:
Nov 1, 2001
Appl. No.:
09/959026
Inventors:
Chuong Q. Dam - San Jose CA
Michael C. Long - Germantown Hills IL
Scott F. Shafer - Morton IL
Jay E. Tomaseski - Gainesville GA
Assignee:
Caterpillar Inc - Peoria IL
International Classification:
F02M 4702
US Classification:
239 88, 2395332, 2395333, 23953311, 23953312, 2395851, 239591
Abstract:
A thin film coating for a low alloy steel or tool steel components in a fuel injector ( ), such as a fuel injector needle valve ( ) is disclosed. A thin film coating ( ) consists of a metal carbon material layer less than 2. 0 microns thick applied to a low alloy steel substrate ( ) or tool steel substrate ( ) used in fuel injector components, such as the fuel injector needle valve ( ) or a portion thereof. Optionally, a thin bond layer ( ) of chromium is deposited between the steel substrate ( ) and the primary metal carbon material coating ( ). The thin film coating ( ) minimizes abrasive and adhesive wear associated with the needle valve ( ) and cooperating nozzle surfaces ( ) of the fuel injector ( ).

Charles Bates - Peoria IL, US
Jay E. Tomaseski - Gainesville GA, US
Alan R. Stockner - Metamora IL, US
Colby Buckman - Peoria IL, US
Assignee:
Caterpillar Inc. - Peoria IL
International Classification:
B05B001/00
US Classification:
239596, 23953311, 2395332, 239 88, 251360, 123299
Abstract:
A nozzle insert that is capable of being irreversibly attached to a needle valve tube such that the resulting needle valve member can be used in a nested needle valve configuration for a dual mode fuel injector.

Fluid Seal For Cyclic High Pressures Within A Fuel Injection

US Patent:
56828616, Nov 4, 1997
Filed:
May 23, 1996
Appl. No.:
8/652174
Inventors:
Alan R. Stockner - Metamora IL
Jay E. Tomaseski - Bloomington IL
Norval J. Wiemken - Dwight IL
Assignee:
Caterpillar Inc. - Peoria IL
International Classification:
F02M 3704
US Classification:
123495
Abstract:
A fuel injector includes an injector body with a plunger bore that opens to a nozzle outlet. A plunger having a pressure face and a side surface is positioned to reciprocate in the plunger bore between an advanced position and a retracted position. A portion of the plunger bore and the plunger define a fuel pressurization chamber that opens to the nozzle outlet. A needle valve is positioned in the injector body adjacent the nozzle outlet and is moveable between an open position which opens the nozzle outlet and a closed position in which the nozzle outlet is closed to the fuel pressurization chamber. An O-ring is in contact with the side surface of the plunger and the plunger bore on the injector body and serves to seal against fuel leakage past the plunger. Pressure acting on the O-ring is attenuated by providing either a pressure accumulation volume between the pressure face end of the plunger and the O-ring and/or a pressure release passage that opens the plunger bore to a low pressure return line below the O-ring.

Fluid Seal For Cyclic High Pressures Within A Fuel Injector

US Patent:
59016868, May 11, 1999
Filed:
Nov 3, 1997
Appl. No.:
8/963315
Inventors:
Alan R. Stockner - Metamora IL
Jay E. Tomaseski - Bloomington IL
Norval J. Wiemken - Dwight IL
Assignee:
Caterpillar Inc. - Peoria IL
International Classification:
F02M37/04
US Classification:
123495
Abstract:
A cyclic high pressure fluid seal for a fuel injector includes an injector body that defines a cyclic high pressure space connected to a low pressure space by a bore. A member with a pressure face end and a side surface is mounted to reciprocate in the bore between a retracted position and an advanced position. An O-ring is positioned in contact with the side surface of the member and the injector body within the bore. A portion of the member and the bore define a pressure accumulation volume positioned between the O-ring and the pressure face end. The pressure accumulation volume is positioned such that fluid pressure in the pressure accumulation volume changes with that of the cyclic high pressure space.
