The pump housing (40) has a high pressure chamber (44) which via. a pliable mouthpiece extension (46) is connected to a pump mouthpiece (48), which connects to a lubricating nipple on an object to be lubricated. The pump mouthpiece is connectable with the feed chamber (30) via a lubricating nipple (52) on the outside of the pump housing. An indicating component (32) in the feed housing can be moved forward to indicate the degree of fill in the lubricating syringe at a rear end of the feed housing (10). This movement is produced by the feed piston (22) when during filling it approaches the feed chamber rear end. The high pressure chamber is provided with a manually activatable pressure unloading valve (56). |
