Abstract: A portable grease gun with a dual pressure output capability which can be selectively changed by the user with little effort. A larger diameter plunger is longitudinally coupled to an extension. The larger diameter plunger and its extension are variable in length by manual rotation of the extension relative to the larger diameter plunger. The larger diameter plunger is slidable within a plunger retainer over a limited range and is not free to rotate within the plunger retainer. The larger diameter plunger and the plunger extension have aligned bores through them in which a smaller diameter plunger is slidable. The smaller diameter plunger moves when an actuating lever is operated to compress grease in the grease gun. The larger diameter plunger may be adjusted to remain static during operation of the actuating lever or it may be adjusted to move during all or part of the compression stroke of the actuating lever.

Abstract: A portable grease gun with the capability of being attached to either a grease containing barrel or a hose carrying grease from a grease supply container. An adapter may be mounted to the barrel mounting in place of a barrel to couple the grease gun to a hose connected to a grease supply container remote from the grease gun. Alternating plug may be mounted in the barrel mounting and a pumped grease supply coupled to the resupply port on the grease gun. The grease gun includes an output valve which restrains passage of grease at pressure below 30 psi.

The smaller diameter plunger moves when an actuating lever is operated to compress grease in the grease gun. The larger diameter plunger may be adjusted to remain static during operation of the actuating lever or it may be adjusted to move during all or part of the compression stroke of the actuating lever. A high pressure can be generated by movement of the smaller diameter plunger alone, or a high flow volume can be generated by movement of the smaller and larger diameter plungers in unison.

Abstract: 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.

Abstract: A battery powered grease gun 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 includes a small relief passageway joined to the output port of the grease gun head which is closed by an adjustable check valve. When the pressure of grease in the output port rises above a preselected pressure, grease will pass through the relief passageway to the grease barrel or, if so equipped, to the grease supply adapter which is mounted to the grease gun head. The grease gun head is additionally provided with a sampling duct which is joined to the output port. The sampling duct couples the output port to another port in which a pressure gauge or a pressure transducer may be installed. The pressure of grease in the output port may be displayed on the pressure gauge or on a display coupled to the transducer.
