Abstract

An accumulator includes an accumulator housing defining a first end, a second end opposite to the first end, and a hollow chamber. The accumulator also includes a piston slidably disposed within the hollow chamber and adapted to displace between the first and second ends. The piston divides the hollow chamber into a gaseous chamber proximate to the first end of the accumulator housing and a hydraulic chamber proximate to the second end of the accumulator housing. Further, the piston defines a first side surface in communication with the gaseous chamber and a second side surface spaced apart from the first side surface. The second side surface is in communication with the hydraulic chamber. A cavity of the piston is in communication with the second side surface and extends from the second side surface towards the first side surface. The cavity is in fluid communication with the hydraulic chamber.
