Improvements in greasing devices, which are essentially characterized by comprising a chamber suitable for housing a container tank of grease or oil, which previously has been removed the bottom and lid, acting from the bottom of the chamber a plunger, with adjustable pressure externally, which moves inside the cartridge by pushing the grease into a pump body through a valve that can be closed in only one direction, so that when the acting lever is operated on the ejection piston, the valve closes, increasing the internal pressure sufficiently. So that it expires a second valve of closing to spring, leaving the grease for it until a forked conduction with two external exits apt for the coupling to any of them of the tube with outlet nozzle, while the other one stays closed with a screw cap .
