摘要： A low inertia, wear-resistant needle valve assembly is provided for an internal combustion engine closed nozzle unit fuel injector. The needle valve assembly includes a needle and spring retainer subassembly made from an advanced structural ceramic, such as silicon nitride. A valve seat subassembly in the injector cup is made from a combination of metal and ceramic. The assembly materials and configuration provide maximum control over the efficiency of the injection event so that the fuel injection event can be terminated quickly, thereby allowing more effective control over exhaust emissions.

摘要： In accordance with preferred embodiments of the invention, a disc-shaped contact pad of ceramic material is disposed within a recess formed in the top surface of a metal valve crosshead. The pad is held in the recess by a retainer that clips onto the crosshead. The retainer is designed to maintain only a light pressure on only a narrow shoulder of the pad to keep it seated, and does not, itself, experience any dynamic loading. Furthermore, by the provision of a circumferential clearance between the pad and both the wall of the crosshead recess and the retainer, the need for precision machining of the ceramic material can be avoided. Additionally, a reduction of frictional sliding forces imposed on the crosshead, and in turn upon the valves, by the rocker lever is achieved by the ceramic pad, so that resultant frictional side loading is not imposed on adjacent valve components to a significant extent.

摘要： A ceramic-metal composite structure which minimizes tensile ceramic loads and accommodates differences in thermal expansion characteristics between a metal member and a ceramic member without reliance on precise feature control for either member. The composite includes a mechanical retainer which allows a loose fitting relationship between the metal and ceramic members. The ceramic member is secured within a receiving bore in the metal member by the retainer in a manner which eliminates the need for precise machining of the ceramic and metal members. The metal member may be configured to accept either an internal or an external mechanical retainer element. The composite ceramic-metal structure of the present invention finds particular utility in forming a durable wear-resistant interface in internal combustion engine actuator or actuating components, such as compression brake master pistons.

摘要： A sliding friction- and wear-resistant elephant's foot or swivel pad adjusting screw assembly for contacting an actuating member interface in an internal combustion engine is provided to transmit arcuate motion into reciprocal motion. The assembly includes a metal screw element configured to move along an arcuate path in a correspondingly configured socket in a ceramic pad element. A retainer element secures the pad element to the screw element loosely to allow this relative motion. The ceramic pad element includes a planar contact face for contacting a corresponding planar contact surface on an internal combustion engine actuating member, such as a valve, a valve crosshead or a unit fuel injector.

摘要： A ceramic-metallic interfacing joint assembly is disclosed. The joint assembly includes a pair of interfaced components in a highly loaded, sliding contact in which the contact stresses can be as high as 250,000 psi. Preferably, the pair of interfaced components includes a ball member and a complementarily shaped, mating socket member and is used in a diesel type internal combustion engine. One of the components is formed of a ceramic material having a density of at least 3.18 g/cm.sup.3 and the other component is formed of a metallic material. Preferably, the density of the ceramic material ranges from 3.18 g/cm.sup.3 to 3.25 g/cm.sup.3. This arrangement reduces the wear of the joint assembly in conjunction with the use of a lubricant which lubricates the components. Specifically, the metallic material is an iron based material while the ceramic material is a sintered silicon nitride. The ceramic material may be sintered with rare-earth metal oxides such as yttrium oxide. Alternately, the ceramic material may be sintered using aluminum oxides.
