Abstract
A suction accumulator for a refrigerant compressor which is mounted to the compressor in such a way as to reduce the metal fatigue at the joint between the inlet tube and the suction accumulator, and reduce the potential for rust or oxidation of the metal of the suction accumulator. The suction accumulator includes a cylindrical housing with two domed ends, wherein an inlet tube extends into the inlet of the suction accumulator and is provided with a flared end. The flared end is attached to the inlet of the suction accumulator and the flared end matches the contour of the inlet such that when the two parts are joined they are congruent with each other to thereby reduce the vibration therebetween. The suction accumulator is also provided with an outlet which communicates refrigerant from the suction accumulator back to the compressor. The suction accumulator is secured to the outside wall of the compressor using a mounting bracket. The mounting bracket is provided with a weld projection aperture and a plurality of weld projections which are used in welding the mounting bracket both to the suction accumulator and to the compressor. The mounting bracket is pre-assembled to the suctio…
