Rationale of the BFG distributor

1.The lubricating oil delivered from the oil pump starts to push upward through the umbrella valve in the BFG distributor.

2.When the umbrella valve closes the central hole of the core rod, the piston is forced to rise against the spring force. Drain the lubricating oil previously stored in the upper chamber.

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

4.When the oil pump stops supplying oil, its pressure relief valve opens automatically, so that the pressure oil in the main oil 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 distributor and enters the oil, the piston presses the lubricating oil stored in the lower chamber to the upper chamber through the small hole of the core rod. , and the next fuel supply is also ready.
