Embodiment Construction

[0023] Hydraulic power units, such as hydraulic accumulator devices, that use compressible fluid to store energy are typically filled, pre-charged or charged with an inert gas such as dry nitrogen. The example accumulator devices described herein may be used with fluid power systems to provide energy storage, fluid compensation, energy accumulation, pulsation dampening, and the like. The example accumulator devices described herein may be fluidly coupled to a fluid power system, such as a hydraulic fluid system, to prevent drastic drops in fluid pressure when the demand on the hydraulic system increases. The fluid power system may provide pressurized hydraulic fluid to operate or actuate control devices, such as hydraulic actuators, downstream of the example accumulator devices described herein.

[0024] A hydraulic fluid system may include a pump upstream of the accumulator device to provide pressurized hydraulic fluid to the exemplary accumulator device when demand on the hy...

Abstract

The present invention describes methods and apparatus for charging accumulators. An exemplary system for charging an accumulator device (100) includes a piston (104) disposed within a housing (102) for defining a first chamber adjacent a first side (106) of the piston and a second chamber adjacent to the second side (108) of the piston. A fill probe (202) has a body and a passageway between a first end (306) of the fill probe and a second end (308) of the fill probe, the fill probe (202) being movable is groundlessly coupled to the piston to fluidly couple the passageway of the fill probe to the second chamber of the housing when the accumulator device is in a charged state. A valve (142) is fluidly coupled to the piston to enable fluid flow through the piston (104) to the second chamber of the housing when the fill probe is coupled to the piston (104) .

Description

technical field [0001] The present disclosure relates generally to accumulators and, in particular, to methods and apparatus for charging accumulator devices. Background technique [0002] Hydraulic power units such as, for example, accumulator devices are often used in hydraulic systems to provide, for example, energy storage, fluid compensation, energy accumulation, pulsation damping, and the like. For example, when used as an energy storage unit, an accumulator device can be used to provide pressurized control fluid (such as hydraulic oil) to equipment that requires high pressure fluid to operate, such as hydraulic equipment, such as cylinders, valve actuators or other machines. For example, an accumulator may be used to store pressurized hydraulic fluid provided by a hydraulic pump when hydraulic system demand is low (e.g., hydraulic actuators are not during startup) to supply the system with previously stored pressurized hydraulic fluid to provide additional energy. ...
