Patent ID: 6845758

Claim:
A retainer assembly for retaining a fuel injector in operable coupling with a cylinder head, the retainer acting in cooperation with a clamping mechanism, the clamping mechanism being in operable engagement with the fuel injector and the cylinder head for exerting a clamping force tending to hold the fuel injector in engagement with the cylinder head, comprising: first retainer means being statically engagable with the cylinder head by a clamping action of the clamping mechanism acting on the fuel injector and being engagable with a second retainer means for imparting a bias to the second retainer means; the second retainer means being in operable engagement with the fuel injector for imparting a reactive force to the fuel injector responsive to the bias imparted by the first retainer means; and frictional coupling means frictionally coupling the first retainer means and the fuel injector for generating a frictional force between the first coupling means and the fuel injector, the frictional force tending to resist motion of the fuel injector relative to the cylinder head.
