Common rail accumulator clamp

An accumulator clamp for an accumulator assembly in an engine assembly of a machine, where the accumulator assembly further includes an accumulator body and a fuel line adapter connected thereto, and the accumulator assembly is mountable to a cylinder head of the engine assembly with an injector end of the accumulator body disposed within a cylinder head accumulator bore of the cylinder head, the accumulator clamp comprising:

• a clamp body having a clamp body front surface, a clamp body rear surface, a clamp body bottom surface, a clamp body top surface, a clamp body first side surface and a clamp body second side surface;
• a clamp accumulator bore extending through the clamp body from the clamp body bottom surface to the clamp body top surface, wherein the clamp accumulator bore is shaped to receive a fuel line adapter connection end of the accumulator body inserted into the clamp accumulator bore through the clamp body bottom surface;
• a first bolt bore extending through the clamp body proximate the clamp body first side surface from the clamp body bottom surface to the clamp body top surface, wherein a first bolt bore inner diameter of the first bolt bore is greater than a first mounting bolt outer diameter of a first accumulator mounting bolt extending from the cylinder head adjacent the cylinder head accumulator bore;
• a first bolt slot through the clamp body from the first bolt bore to the clamp body front surface, with the first bolt slot extending upwardly from the clamp body bottom surface and having a first bolt slot width that is greater than the first mounting bolt outer diameter;
• a second bolt bore extending through the clamp body proximate the clamp body second side surface from the clamp body bottom surface to the clamp body top surface, wherein a second bolt bore inner diameter of the second bolt bore is greater than a second mounting bolt outer diameter of a second accumulator mounting bolt extending from the cylinder head adjacent the cylinder head accumulator bore;
• and
• a second bolt slot through the clamp body from the second bolt bore to the clamp body front surface, with the second bolt slot extending upwardly from the clamp body bottom surface and having a second bolt slot width that is greater than the second mounting bolt outer diameter, and
• wherein the clamp accumulator bore, the first bolt bore and the second bolt bore are positioned so that the first accumulator mounting bolt and the second accumulator mounting bolt can be inserted through the first bolt slot and the second bolt slot and into the first bolt bore and the second bolt bore, respectively, when the injector end of the accumulator body is inserted into the cylinder head accumulator bore.

An accumulator assembly for an engine assembly of a machine having a cylinder head with a cylinder head accumulator bore, a first accumulator mounting bolt having a first mounting bolt outer diameter and extending from the cylinder head adjacent the cylinder head accumulator bore, and a second accumulator mounting bolt having a second mounting bolt outer diameter and extending from the cylinder head adjacent the cylinder head accumulator bore, the accumulator assembly comprising:

• an accumulator body having a fuel line adapter connection end, an injector end disposed longitudinally opposite the fuel line adapter connection end, and an accumulator body outer surface having a shape that is complimentary to the cylinder head accumulator bore to facilitate insertion of the injector end into the cylinder head accumulator bore;
• a fuel line adapter;
• and
• an accumulator clamp comprising
• a clamp body having a clamp body front surface, a clamp body rear surface, a clamp body bottom surface, a clamp body top surface, a clamp body first side surface and a clamp body second side surface,
• a clamp accumulator bore extending through the clamp body from the clamp body bottom surface to the clamp body top surface, wherein the clamp accumulator bore is shaped to receive the fuel line adapter connection end of the accumulator body inserted into the clamp accumulator bore through the clamp body bottom surface,
• a first bolt bore extending through the clamp body proximate the clamp body first side surface from the clamp body bottom surface to the clamp body top surface, wherein a first bolt bore inner diameter of the first bolt bore is greater than the first mounting bolt outer diameter,
• a first bolt slot through the clamp body from the first bolt bore to the clamp body front surface, with the first bolt slot extending upwardly from the clamp body bottom surface and having a first bolt slot width that is greater than the first mounting bolt outer diameter,
• a second bolt bore extending through the clamp body proximate the clamp body second side surface from the clamp body bottom surface to the clamp body top surface, wherein a second bolt bore inner diameter of the second bolt bore is greater than the second mounting bolt outer diameter, and
• a second bolt slot through the clamp body from the second bolt bore to the clamp body front surface, with the second bolt slot extending upwardly from the clamp body bottom surface and having a second bolt slot width that is greater than the second mounting bolt outer diameter,
• wherein the fuel line adapter connection end of the accumulator body is inserted into the clamp accumulator bore through the clamp body bottom surface and the fuel line adapter is coupled to the fuel line adapter connection end.
