Abstract:
a cast engine block having an upper portion with a plurality of cylinders and a lower portion with an improved crankcase which has opposed, spaced, support members positioned between adjacent cylinders, each support member having a mounting surface; a bearing assembly including a conventional cast lower bearing cap and upper steel-forged bearing cap having an arcuate central portion with projecting end portions positionable against the mounting surface of the support member; and means for securing the lower bearing cap and the upper bearing cap to the support members of the engine block.
Abstract:
The system comprises a water jacket having liquid cooling means for cooling the upper cylinder section, and, wherein the lower cylinder has a plurality of outwardly directed cooling fins extending between the outer housing wall of the upper cylinder section of the cylinder housing and bell-shaped crankcase housing. The fins are parallel to the center axis of the cylinder and both reinforce the engine block casting and cool the lower cylinder section.
Abstract:
A light alloy piston (1) for an internal combustion engine has a recess (2) in its crown to receive a ceramic insert which is cast in position. A number of small dia. holes (4,5) are drilled through the crown from its inner surface to the floor of the recess. The under- surface of the cylinder head in the region forming part of the combustion chamber is fitted with similar ceramic inserts and provided with similar holes (4,5). The holes allow the escape of the gases, which collect between the insert and the surrounding metal, to escape and so prevent the insert from being forced out by the gas pressure.
Abstract:
A light-weight, high-strength compressor component having at least one fluid delivery feature that is formed via additive manufacturing is provided. The component may have at least one interior region comprising a lattice structure that comprises a plurality of repeating cells. A solid surface is disposed over the lattice structure. The interior region comprising the lattice structure has at least one fluid delivery feature for permitting fluid flow through the body portion of the light-weight, high-strength compressor component. The fluid delivery feature may be a flow channel, a fluid delivery port, a porous fluid delivery feature, or the like that serves to transfer fluids through the component, such as refrigerant and/or lubricant oils. Methods of making such compressor components via additive manufacturing processes are also provided.
Abstract:
One example of a gerotor pump includes an inner rotor comprising multiple teeth, the inner rotor configured to rotate about a first longitudinal gerotor pump axis. The gerotor pump also includes a hollow outer rotor including an outer surface and an inner surface having substantially identical contours, the inner surface configured to engage with the multiple teeth and to rotate about a second longitudinal gerotor pump axis. The pump includes a pump housing within which the inner rotor and the outer rotor are disposed, wherein the outer surface of the outer rotor defines gaps between the pump housing and the outer rotor.
Abstract:
Es wird ein Gehäuse eines Klima-Kompressors (1) für den Betrieb mit dem Kältemittel R744 bestehend aus mindestens zwei Gehäusebauteilen (2) vorgeschlagen, wobei die mindesten zwei Gehäusebauteile (2) gegeneinander gedichtet und mit Schrauben (3) miteinander verbunden sind, und die Gehäusebauteile (2) aus Aluminium oder einer Aluminiumlegierung bestehen und die Schrauben (3) ultrahochfeste Schrauben gemäß der Normierung VDA 235-205 sind. Zusätzlich können Flachdichtungen (4) zwischen den Gehäusebauteilen (2) vorgesehen sein. Ultrahochfeste Schrauben sind Mittel um zusätzlich Überdruck-Sicherheitsfunktion im Berstfall zu gewährleisten.
