Abstract
An accumulator includes a canister, a piston, a sleeve, and a solenoid control valve assembly. The canister has an inner surface that defines an interior volume. The piston is slidably disposed within the interior volume of the canister. The piston is located between the inner surface of the canister and an outer surface of the sleeve. The piston divides the interior space into a fluid filled chamber and an air filled chamber. A fluid pathway is created by an outer surface of the sleeve and the inner surface of the canister. The fluid pathway allows fluid from an exterior source to either enter or exit the fluid chamber. The solenoid control valve assembly includes a valve body, a valve biasing member, and a plunger that is slidable within a recess of the valve body.
