CA 2605218
A battery powered grease gun is disclosed. One embodiment has an overpressure relief valve for returning grease to the grease barrel mounted to the grease gun head when a plugged zerk prevents grease from exiting the output port. The grease gun head may be additionally provided with a sampling duct which is joined to an output port. The sampling duct couples the output port to another port in which a pressure gauge or a pressure transducer may be installed. In one embodiment, a strain gauge based pressure transducer may be attached to the grease gun to monitor the flow and pressure of grease in the grease gun. The pressure and/or flow of grease may be displayed on the pressure gauge or on a display coupled to the transducer.
