Problems solved by technology

[0007] This current charging system is bulky and not easily mobile, making it difficult to carry out the charging process in the field
Such pressurization systems are expensive and cumbersome to operate, which creates the risk of damage to parts and the cost of repair or replacement
Additionally, current systems require lengthy and complex pressurization procedures, which also increase risk, expense, and require user training

Embodiment Construction

[0026] figure 1 An exemplary machine 10 is shown with a hydraulic hammer 20 . Machine 10 may be configured to perform work associated with a particular industry, such as mining or construction. For example, machine 10 may be a backhoe loader (in figure 1 shown in ), excavators, skid steer loaders, or any other machinery. Hydraulic hammer 20 is pivotally connected to machine 10 via boom 12 and boom 16 .

[0027] In the disclosed embodiment, one or more hydraulic cylinders 15 may raise, lower and / or swivel boom 12 and boom 16 to correspondingly raise, lower and / or swivel hydraulic hammer 20 . Hydraulic cylinder 15 may be connected in known manner to a hydraulic supply system (not shown) within machine 10 . In the illustrated embodiment, machine 10 includes a pump (not shown) connected to hydraulic cylinder 15 and to hydraulic hammer 20 through one or more hydraulic supply lines (not shown for clarity). A hydraulic supply system may direct pressurized fluid, such as oil, fro...

Abstract

An adapter for conveying pressurized gas to an accumulator includes a proximal end to receive the canister and establish a fluid communication passage between an interior thereof and an interior of the accumulator. A distal end is configured to engage the accumulator to establish the fluid communication passage. A housing body includes one of the proximal and distal ends and forms a chamber. An adjuster body is adjustably disposed in the housing body. The adjuster body includes the other of the proximal and distal ends and includes adjuster threads configured to engage housing threads to adjust a position of the adjuster body in the housing body. The adjuster body includes an adjustable shut off valve movably disposed in the chamber to close fluid flow through the passageway wherein moving the adjuster into the housing increases pre-load to increase the force necessary to open the shut off valve.

Description

technical field [0001] The present invention relates generally to machines employing hydraulic accumulators, and more particularly to systems and methods relating to charging hydraulic accumulators. Background technique [0002] In large industrial machines, such as mining and haul trucks, it is not possible for a human operator to manually generate a force large enough to effectively brake or steer the machine. As a result, most large machines employ hydraulic power brakes and hydraulic power steering systems that use hydraulic power to augment the operator's manual force input. Thus, these and other like power systems direct the flow of high pressure hydraulic fluid to the mechanical actuation or steering actuators to implement the actuation and steering commands given by the operator. [0003] Such machines may also utilize high pressure hydraulic fluid to operate various implements, tools and tool systems. While hydraulic pumps are capable of supplying the flow require...
