Principle of operation
Monnier lubricators are used to maintain the proper ratio of oil and air and to maximize the performance and guarantee long life of pneumatic machinery. Once the oil rate has been set, a Monnier lubricator provides reliable automatic lubrication. The Monnier design ensures efficient and dependable performance. The Monnier Venturi valve ( 1 ) automatically maintains the ratio of oil to air that the user selects. It assures lubrication even at the lowest possible air flow (see Capacities on page 3). By automatically increasing the air pressure behind the oil in the main reservoir ( 2 ) in proportion to the increased air flow, the Venturi valve provides the desired degree of lubrication regardless of air flowrate. The Monnier sight dome ( 3 ) is moulded from transparent polycarbonate that can be viewed at a full 360 ° . It includes an adjustment screw ( 4 ) for setting the oil rate, and a sight-feed tube ( 5 ) where the oil can be visually measured, drop by drop. As standard, each lubricator is supplied with a " diameter tamper-proof ball ( 6 ) that may be pressed or tapped into the top of the sight dome adjustment area after the oil rate has been set. This prevents any further adjustment by unauthorized personnel.
