Abstract
Official abstract text for this publication.
A fuel injection valve damping insulator damps vibration produced in a fuel injection valve ( 11 ). A damping insulator ( 30 ) is interposed between a shoulder portion ( 18 ) of a cylinder head and a tapered surface ( 24 ) of the fuel injection valve ( 11 ) that faces the shoulder portion. The damping insulator ( 30 ) includes an annular tolerance ring ( 33 ) that abuts against the tapered surface ( 24 ), and an elastic member ( 36 ) that is arranged between the tolerance ring ( 33 ) and the shoulder portion ( 18 ). An annular coil spring ( 34 ) and a sleeve ( 35 ) are each embedded juxtaposed in the elastic member ( 36 ). A height (H 2 ) of the sleeve ( 35 ) is formed lower than an outer diameter (H 1 ) of individual small ring portions that form a helix of the coil spring ( 34 ), and at least one of a tolerance ring ( 33 ) side and a shoulder portion ( 18 ) side of the sleeve ( 35 ) is buried in the elastic member ( 36 ).
First claim
Opening claim text (preview).
The invention claimed is: 1. A fuel injection valve damping insulator that damps vibration produced in a fuel injection valve, the fuel injection valve being installed in a cylinder head in a state inserted into an insertion hole provided in the cylinder head, a shoulder portion being formed widening out in an annular shape at an inlet portion of the insertion hole, the fuel injection valve including a stepped portion in which a diameter thereof increases in a tapered shape so as t…
