AI Technical Summary

Problems solved by technology

Manufacturing hollow pistons from separate pieces of material increases the complexity and cost of manufacturing the pistons, creates waste due to waste from circular cutouts, and increases susceptibility to wear, stress, and damage (e.g., in The inner part and the outer part are attached to the middle surface of the piston at the weld seam site)
For example, friction can cause multiple parts that have joined together to separate from each other

Abstract

Disclosed are hollow pistons made from a single piece of starting material and methods of manufacturing hollow pistons from the single piece of starting material.

Description

technical field [0001] The present invention relates generally to a hollow piston and, in particular, to a hollow piston formed from a single piece of material which may be used, for example, in a compression system. Background technique [0002] A common type of compression system for air conditioning in motor vehicles is a positive displacement compressor, which can be either constant or variable. Although various compressor configurations exist, such positive displacement compressors basically operate on the same basic principle: a certain suction volume of gas is confined within a given space, compressed as the size of the space decreases, and then Higher pressure discharge. [0003] One type of positive displacement compressor includes a reciprocating piston to effect compression. In one compressor design, a solid cylindrical piston moves axially within a cylindrical bore in the compressor housing. On the downstroke (or suction stroke), a low-pressure area is formed,...
