Abstract: A maximum-pressure plunger plump has, coaxial with its longitudinal axis, a compression valve and a suction valve. It has a sleeve that floats on a plunger. The sleeve rests on the end facing the head of the pump on an inset. the inset is provided with a seat area for the body of the suction valve and with suction channels. The sleeve has a bushing. The suction valve is in a form of a disk. It has a spring-loaded annular body that rests on the valve-seat area that the suction channels open out of in the insert in the pump head.The plunger's bushing (9) extends to th eend of the sleeve (7) that faces the head (2) of the pump with its face against the insert (12) and in that a sealing sleeve (15) that overlaps the area or seam of impact between the insert and the sleeve is accommodated in the flow channel between the bushing and the insert.

Abstract: A heat resistant and wear resistant iron-based sintered alloy for use as the material of an engine component part which is subjected to severe temperature and wear conditions. The iron-based sintered alloy is comprised of a matrix formed of metal powder having the composition of alloy steel or high speed tool steel. An additional metal component formed of hard alloy powder is dispersed in the matrix in an amount ranging from 3 to 50% by weight of the matrix. The hard alloy powder contains as major components iron, molybdenum and silicon which improve the wetting property of the hard alloy powder with the matrix and form intermetallic compounds which are high in hardness and excellent in heat and oxidation resistances.

Abstract: Method of dimensionally stabilizing the interface between metal parts of differing thermal expansion characteristics (TEC), regardless of temperature variations under normal designed use of such parts, comprising: (a) hot extruding a mixture of ceramic fibers (i.e., Si.sub.3 N.sub.4, SiC, Al.sub.2 O.sub.3) and a powder of the metal having the higher TEC (i.e., Al, Ti, Mg) while aligning the fibers generally along the direction of extrusion, to form an insert; (b) shaping the insert to align its fibers generally in at least one direction of anticipated thermal growth that may interfere with the interface; (c) casting the insert in place within a first part compound of the higher TEC metal and with the insert's fibers (i) oriented as above, and (ii) preheated to a temperature no greater than 35-45% of the temperature of the molten light metal; and (d) bringing together the first metal part with a second part of lower TEC metal (i.e., Fe or steel) to form the interface. The insert may be located in a mold in a manner to be totally enveloped by the molten light metal with the insert having a surface spaced a uniform, predetermined distance from the exterior of the cast light metal part, or the insert may be located to expose a surface thereof upon completion of the casting.

Abstract: An aluminium alloy made of consolidated rapid-quenched aluminium alloy powder by using an improved metallurgical method basically comprises, by weight percent, less than 30% silicone, less than 8% iron, less than 7% copper and less than 0.2% oxygen, the balance being substantially aluminium. The consolidated rapid-quenched aluminium alloy powder has features that it contains less than 0.2% oxygen, and the material made from the rapid-quenched aluminium alloy powder has a high limit compressibility factor, rate of reduction and tensile strength. Thus the aluminium alloy material obtained is suitable for structural members such as pistons for internal combustion engines.

Abstract: The crankshaft of an engine is supported by bearing caps mounted on journal walls of a cylinder block and a bridge interconnects the bearing caps. Oil passages in each bearing cap lead from the bridge to each crankshaft journal bearing at a laterally offset location rather than on the cylinder axis. A longitudinal main gallery in the bridge supplies oil to the passages and is laterally offset even further to that side. A supply passage in the bridge and one bearing cap at one extreme lateral side supplies oil from a pressurized oil supply passage in the cylinder block to that supply passage in the bearing cap.

Abstract: An internal combustion engine has an integral cylinder block, crankcase and sump structure made in two halves 1, 2. The material of the halves is chosen for lightness. The pressure pulsations in the cylinders are taken by long steel bolts 14, 15 which extend from the top of the cylinder head to a bearing structure comprising yokes (steel clamping members 8, 9 clamped together by traverse fasteners 12, 13) holding together the two main crankshaft bearing housing halves 6, 7 which are formed integrally with each half of the integral engine structure. The integral halves do not have re-entrants and can be produced simply by casting, pressing or moulding.

Abstract: A reciprocating type gas compressor comprises a hollow frame or housing having spaced apart end walls, a motor-driven crankshaft disposed within the housing and rotatably mounted on bearing assemblies on the end walls and connecting rods connected to crank pins on the crankshaft for driving pistons located within the housing. The crankshaft comprises a drive shaft at one end and a pump shaft the other end, both extending along a common axis of rotation. The crankshaft also comprises a pair of axially spaced apart counterweights located between the two shafts and a crank arm or link located between the counterweights. A crank pin extends from each counterweight to the link along a pin axis which is parallel to and spaced apart from the common axis of rotation. Each bearing assembly has a hollow cylindrical inner race which is friction-fitted on a shaft at an end of the crankshaft and abutts the side of one counterweight. To enable removal of each friction-fitted bearing assembly from its shaft without damage thereto, a pair of threaded bores extend through portions of each counterweight and the bore axes are parallel to but located on opposite sides of the common axis of rotation and each bore is aligned with the inner end surface of the inner race of the associated bearing assembly. Each threaded bore accommodates a long jack screw which is temporarily rotatably inserted thereinto so as to engage the inner race and force the bearing assembly off of its shaft for servicing or replacement.
