Abstract

A lubricant pump for use with pneumatic equipment is actuated by the pressure of the air which operates are the equipment. The pump has a cylindrical body which houses a piston (3) and two non-return valves (5, 6). When the air pressure in the pipe (10) rises above a given value, the piston (3) is pushed upwards against the spring (4) and increases the oil pressure in the space (A). This increase in oil pressure closes the upper non-return valve and at the same time opens the lower non-return valve (6) allowing the oil in the space (A) to flow into the pipe.
