accumulator

accumulator
i. A reservoir that supplies fluid under pressure, when desired. In a typical hydraulic system, it consists of a steel cylinder closed at one end and connected to the pressure line at the other, as well as a floating piston. The piston separates hydraulic fluid from compressed nitrogen/air. Hydraulic fluid under pressure can be stored in the system. The accumulator reduces the pump’s peak demands, dampens the pressure ripple, and acts as a reserve of fluid and an emergency power source.

ii. A device sometimes incorporated into the fuel system of a gas turbine engine to store and release fuel under pressure as an aid in starting. Also called a collector.
iii. A device for storing fuel in a fuel tank for inverted flying.
iv. In pneumatic and oxygen systems, the reservoir where compressed air or oxygen is stored.
