Abstract

Official abstract text for this publication.

An electromagnetic valve used in a fuel system, in which at least a portion of a member constituting an magnetic circuit in an electromagnetic drive unit includes 0.15-0.45 mass % (inclusive) Ni, 0.65-1.0 mass % (inclusive) Al, 9.2-10.3 mass % (inclusive) Cr, and 0.90-1.6 mass % (inclusive) Mo, and the remainder comprises an alloy material comprising Fe and unavoidable impurities. The alloy material may further include 0.05-0.15 mass % (inclusive) Pb.

First claim

Opening claim text (preview).

The invention claimed is: 1. An electromagnetic valve used in a fuel system, comprising a member constituting a magnetic circuit in an electromagnetic drive unit, wherein at least a part of the member is made of an alloy material comprising, in mass %, 0.15%≤Ni≤0.45%, 0.65%≤Al≤1.0%, 9.2%≤Cr≤10.3%, and 0.90%≤Mo≤1.6% with the balance being Fe and inevitable impurities. 2. The electromagnetic valve according to claim 1 , which comprises a fuel injection valve. 3. The electromagnetic valve according to claim 1 , wherein the alloy material further comprises 0.05%≤Pb≤0.15% in mass %. 4. The electromagnetic valve according to claim 2 , wherein the alloy material further comprises 0.05%≤Pb≤0.15% in mass %. 5. The electromagnetic valve according to claim 1 , wherein the alloy material has a structure of an α phase single phase. 6. The electromagnetic valve according to claim 2 , wherein the alloy material has a structure of an α phase single phase. 7. The electromagnetic valve according to claim 3 , wherein the alloy material has a structure of an α phase single phase. 8. The electromagnetic valve according to claim 4 , wherein the alloy material has a structure of an α phase single phase.
