| 182 | Snap-in connection for pumping plunger sliding shoes | US09339370 | 1999-06-24 | US06183212B2 | 2001-02-06 | Ilija Djordjevic |
| A fuel supply pump having a plurality of radially disposed plunger sleeves each containing a pumping plunger with a driven end reciprocally movable within the plunger sleeve between a pumping position and a filling position. The fuel supply pump includes a rotatable drive member and a plurality of sliding shoes. Each shoe has a first face adjacent a respective plunger driven end and a second face adjacent the drive member. In one variation, each shoe first face includes a socket which the plunger driven end snaps into and is captured by, creating a sliding shoe assembly. A case couples all of the sliding shoe assemblies. In another variation, the cage includes apertures which the plunger driven end snaps through, thereby capturing the plunger. The plunger driven end engages a seat included on the sliding shoe first face. Rotation of the drive member moves each shoe, and thereby, each plunger toward the pumping position. As one plunger is actuated toward the pumping position by the eccentric member at least one plunger is retracted to the filling position by the coupling of the cage. The coupling of the shoe assemblies and the cage allows for the creation of a controlled gap between the a shoe second face and the drive member for part of the drive member rotation. Also a method of fuel supply pump assembly using sub-assemblies which can be assembled externally to the fuel supply pump body. | ||||||
| 183 | Method for forming a fiber reinforced ceramic matrix composite | US84270 | 1998-05-26 | US6030563A | 2000-02-29 | Thomas Edward Strasser; Steven Donald Atmur |
| A heat-resistant, thermally insulative, ductile port liner for a head of an internal combustion (IC) engine having a tube-shaped structure formed from at least one layer of fiber reinforced ceramic matrix composite (FRCMC) material. The FRCMC material includes a polymer-derived ceramic resin in its ceramic form and fibers. In a first embodiment of the port liner, the tube-shaped structure has one FRCMC layer forming the sole, solid wall of the structure. Whereas, in a second embodiment, the tube-shaped structure has two FRCMC layers forming inner and outer walls of the structure, respectively, with an intervening space separating the inner and outer walls. The intervening space is sealed at both ends. It can be filled with a thermally insulating material, evacuated and held at substantially a vacuum pressure, or filled with a gas. Once the port liner has been formed, it is preferably cast-in-place when the metal head of the IC engine is formed. This entails positioning the port liners within a mold designed to form the metal head in locations corresponding to the intake and exhaust ports of the head. Then, the mold is filled with molten metal to form the head with the port liners being integrally cast therewith. | ||||||

| 185 | Scroll compressor and method for manufacturing an oldham ring therefor | US910337 | 1997-08-13 | US5931651A | 1999-08-03 | Hiroyuki Kawano; Hideo Hirano; Hideto Oka |
| A scroll compressor having an extended life due to the support structure for the orbiting scroll, even when using a chlorine-free substitution refrigerant. The support structure includes an Oldham ring for supporting an orbiting scroll so as to allow the orbiting scroll more orbiting motion without rotating about a fixing scroll. The Oldham ring is formed of a different material from both a fixing member and the orbiting scroll. Hence, if a boundary lubrication state occurs in mutually sliding parts, only sliding between different materials occurs, and mutual adhesion in the portion of the boundary lubrication state is avoided. As a result, the shortening of the life due to the wearing of the support structure of the orbiting scroll is prevented. | ||||||

| 190 | Sliding material | US962950 | 1997-10-21 | US5792717A | 1998-08-11 | Hirokazu Takayama |
| Sliding material comprising a porous ceramic body that has the open pores filled with a high water absorbing resin, preferably to an open pores porosity of ca. 5-15%. The sliding material may be used to fabricate members of the stationary part of a journal bearing in a pump for use in both a fluid and a gaseous atmosphere; members of the rotating part of the bearing are formed of a cemented hard alloy. Since the resin absorbs and retains water, the sliding material will exhibit satisfactory performance even if it is exposed to a gaseous atmosphere without lubrication. Consistent sliding performance is insured not only in fresh water but also in fluids such as slurries that contain hard solid matter. | ||||||

| 198 | Ceramic tile expansion engine housing | US70524 | 1993-06-03 | US5404793A | 1995-04-11 | Blake Myers |
| An expandable ceramic tile housing for a high temperature engine is disclosed wherein each tile is independently supported in place in an interlocking matrix by retention mechanisms which mechanically couple the individual ceramic tiles to an outer metal support housing while maintaining thermal isolation of the metal housing from the ceramic tiles. The ceramic tiles are formed with either an octagonal front face portion and a square shank portion or a square front face portion with an octagonal shank portion. The length of the sides of the octagonal front face portion on one tile is equal to the length of the sides of the square front face portion of adjoining tiles to permit formation of an interlocking matrix. Fibrous ceramic sealing material may be placed between radial and tangential facing surfaces of adjacent tiles to limit radial gas flow therebetween. Labyrinth-sealed pressure-controlled compartments may be established between the tile housing and the outer metal support housing to control radial gas flow. | ||||||

| Ceramic materials to be insert-cast are disclosed, which each contain not less than 65% by volume of aluminum titanate as a crystalline phase, and have an average particle diameter of crystals thereof being not less than 10 .mu.m, Young's modulus of 50 to 2,000 kgf/mm.sup.2, compression strength of 5 to 40 kgf/mm.sup.2, and porosity of 5 to 35%. Ceramic port liners are also disclosed, which are free from cracking due to compression force during insert-casting, peeling-off during use, and facilitate insert-casting. To attain this, a reinforcement which meets either one or both of requirements that differences in coefficient of thermal expansion at 800.degree. C. and Young's modulus between the reinforcement and a material constituting the port liner body are in a range of .+-.0.1% and in a range of .+-.1,000 kgf/mm.sup.2, respectively, is filled into a depressed portion at an outer peripheral surface of the port liner body to form an integrated structure with a flat or swelled surface. Alternatively, the outer peripheral surface of the port liner body is worked to give uneven portions at a joining surface of the port liner body to a metal to insert-cast the port liner. Another alternative is to utilize a stress-releasing slit formed in a wall of the port liner body. Further, the outer peripheral surface of the ceramic port liner body may be covered with a ceramic sheet which is irreversively expandable by heating. | ||||||

| A rotary compressor has a plate-like hollow vane disposed in sliding contact with a rotary piston. The vane has an internal cavity formed by a plurality of bores each having a substantially rectangular cross-section. The corners of each bore are each formed by a curved concave surface of a radius of curvature which is greater than the thicknesses of the outer walls of the vane. The major side surfaces of the vane are in slidable contact with opposing walls of a vane slot and have surface layers each formed of an oxide film consisting mainly of tri-iron tetraoxide (Fe.sub.3 O.sub.4). The film is finished by smoothing processing, thus attaining a smaller friction between the vane major side surfaces and the vane slot walls and suppressing local wear of the vane slot walls. | ||||||
