ABSTRACT A grease gun is fed from a constant supply under pressure. The gun has a hand pumped lever for delevering shots of grease either at high pressure and low volume or low pressure and high volume depending on a changeover valve. Air bleeds from the gun through the nozzle by a single pump of the lever. The lever causes a pushrod to open a one way valve allowing grease to travel entirely through the gun to the nozzle. In another version the pushrod is replaced by a cone valve. Both versions are for single handed operation.
