Space saving high pressure fluid supply clamp for a fuel injector

摘要

A hydraulically actuated fuel injection system includes an actuation fluid supply pipe having a flange. A hydraulically actuated fuel injector has a centerline, at least two different clamping surfaces and a side surface with an actuation fluid inlet. The clamping surfaces are positioned on opposite sides of the centerline. A clamp is attached to the flange of the actuation fluid supply pipe around the centerline of the injector while bearing against the at least two different clamping surfaces. The clamp allows for reliable sealing in a small space while minimizing internal distortion to injector components.
