Abstract
An accumulator assembly is includes a piston located within a pressure canister. The pressure canister has a piston stop therein. The piston stop is located radially outboard of a biasing member or spring located within the pressure canister between the pressure canister and the piston. A support bracket is disposed on an end of the pressure canister in alignment with the spring. The outboard piston stop and the support bracket reduce the stresses due to reaction forces when the accumulator assembly is fully charged. By reducing the stresses due to reaction forces, the accumulator assembly can be made from steel casting or plastic molding without sacrificing the charge capacity of the accumulator assembly.
