Abstract: A compressor used in a refrigerating cycle is provided as a miniaturized and lightweight unit at low production cost by selecting an optimal material to constitute components or by forming the housing in a specific shape so as to allow the components to have smaller wall thicknesses while assuring sufficient strength. A tough material achieving a tensile strength greater than 800N/mm 2 is used when forming at least one of the components constituting the housing and the internal mechanisms. In addition, over the area of the housing where the bottom surface and the inner circumferential surface connect with each other, the bottom surface forms an R-shaped portion and the inner circumferential surface forms a sloping portion or an R-shaped portion.

Abstract: PROBLEM TO BE SOLVED: To provide a piston for an in-cylinder fuel-injection type internal combustion engine having a low thermal conductive material capable of further improving heat insulating property. SOLUTION: This piston for in-cylinder fuel-injection type internal combustion engine has a low thermal conductive member comprising low thermal conductive base material, and coating layer including alumina (Al 2 O 3 ) fine particles adhering on at least part of a cast-in surface cast in a piston body part at one surface side of the low thermal conductive base material cast in a piston top part. A heat insulating layer comprising the coating layer and or an air gap layer caused by the same is formed between the low thermal conductive member and the piston body thereby. As a result, low thermal conductivity of a fuel impingement zone can be easily improved as compared to a case that the low thermal conductive member is simply cast in. COPYRIGHT: (C)2010,JPO&INPIT
