#CMT# #/CMT# The gun (1) has a container (3) for grease, and a plunger (17) moved within an interior of the container for emptying the container. The plunger is moved along length of a container inner space (8) up to bottom of the container inner space. The container is provided with an outlet (13) at the container bottom, which is connected with a pumping device of a grease lubrication system. The plunger comprises a seal (23) that is formed around circumference of the plunger and radially adjusted by an adjustment unit. #CMT# : #/CMT# An independent claim is also included for a method for supplying grease to a consumer by a grease gun. #CMT#USE : #/CMT# Grease gun for a grease lubrication system e.g. wind turbine or car-mounted crane, for supplying grease to a consumer. #CMT#ADVANTAGE : #/CMT# The plunger comprises the seal that is formed around the circumference of the plunger and radially adjusted by the adjustment unit, thus avoiding entry of dirt or other contaminants into the container during transport and temporary storage of the grease. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a partial longitudinal sectional view of a grease gun. 1 : Grease gun 3 : Container 8 : Container inner space 13 : Outlet of container 17 : Plunger 23 : Seal.
