Performance and Features:

1, each fixed flow to supply the lubrication part;

2, not due to the viscosity of oil and the length of time to affect the flow;

3. It must be used with a volumetric oiler with a depressurization device.

Working principle diagram：

1. The lubricating oil delivered from the oil pump at medium pressure makes the bevel valve in the distributor start to push upward;

2. When the umbrella valve closes the central hole of the core rod, it forces the piston to overcome the spring force and begin to rise. Discharge the lubricating oil originally stored in the upper chamber;

3. When the piston moves to the top of the chamber, the oil discharge is completed at the same time;

4. When the oil pump stops supplying oil, the pressure relief valve automatically opens, so that the pressure oil in the main pipe returns to the oil through the pressure relief valve. At this time, the system pressure drops, and the piston in the distributor begins to recover under the action of the spring. When the umbrella valve returns to close the oil inlet of the distributor, the piston will press the lubricating oil stored in the lower chamber to the upper chamber through the small hole of the core rod, and the next oil supply is also ready.
