1. A lubricant delivery apparatus configured for installation within a device that includes a moving component that is actuated by an actuating fluid from an actuating fluid source of the device, comprising:
a lubricant supply reservoir configured for storing a supply of lubricant;
a pump operably coupled to the lubricant supply reservoir for receiving a pre-determined amount of lubricant from the lubricant supply reservoir and discharging the pre-determined amount of lubricant from the lubricant delivery apparatus via a lubricant discharge port; and
an actuating fluid communication port configured for operably coupling to the actuating fluid source such that the actuating fluid communication port is in fluid communication with the actuating fluid source associated with the moving component of the device for receiving a flow of actuating fluid in response to actuation of the moving component by the actuating fluid from the actuating fluid source and for returning the actuating fluid to the actuating fluid source;
the lubricant delivery apparatus having:
a non-actuated state, wherein the predetermined amount of lubricant is disposed within the pump and the pump is disposed for receiving actuating fluid from the actuating fluid source of the device via the actuating fluid communication port; and
an actuated state wherein the predetermined amount of lubricant is discharged from the pump via a lubricant discharge port;
and
while the lubricant delivery apparatus is installed on the device, the actuating fluid communication port is configured for receiving actuating fluid from the actuating fluid source in response to transitioning of the moving component from a non-actuated state to an actuated state and for discharging actuating fluid for returning the actuating fluid to the actuating fluid source in response to transitioning of the moving component from the actuated state to the non-actuated state such that actuation of the moving component is with effect that:
actuating fluid is supplied to the lubricant delivery apparatus via the actuating fluid communication port; and
the lubricant delivery apparatus transitions from the non-actuated state to the actuated state.
