Abstract
A flow control handle for supplying lubricant to a grease fitting. The handle includes a flow control valve interiorly thereof, a handle extension and a manual trigger for controlling the flow control valve. A pressure relief valve is operable to relieve high pressure grease in the handle extension. This valve is automatically closed and is opened by movement of the trigger in a direction opposite to that required to open the flow control valve whereby high pressure grease cannot enter the extension when the relief valve is open.
