Abstract
Official abstract text for this publication.
According to a method of detecting a lift amount of a valve, an area-increasing jig is attached to an upper surface of a retainer attached to the valve. The area-increasing jig has a larger width than a width of the upper surface of the retainer. Then a lift amount of the valve is detected by measuring a distance to the area-increasing jig by using a non-contact sensor disposed above the retainer.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of detecting a lift amount of a valve, the method comprising: attaching an area-increasing jig to an upper surface of a retainer attached to the valve, the area-increasing jig having a larger width than a width of the upper surface of the retainer; and detecting a lift amount of the valve by measuring a distance to the area-increasing jig by using a non-contact sensor disposed above the retainer. 2. The method according to claim 1 , wherein the area-increasing jig is in a form of a plate and includes a groove continuously extending from a portion of a side surface of the area-increasing jig toward a center of the area-increasing jig.
