Integral pressurized grease dispenser

Rationale of the GFG/GFH distributor

The lubricating oil delivered from the oil pump starts to push upward through the umbrella valve in the GFG/GFH distributor.When the umbrella valve closes the central hole ofthe core rod, the piston is forced to rise against the spring force. Drain the lubricating oilpreviously stored in the upper chamber.

When the piston moves to the top of the upper chamber, the oil discharge is completed at the same time.When the oil pump stops supplying ol, its pressure reief valve opens automaticaly, so that the pressure oilin the main oll pipe reset to the oithrough the pressure relief valve. At this time,the svstem pressure drops, and the piston in the distibutor begins to recover under the aclionof the spring. When the umbrella valve reposition to close the distributor and enters the ol, the piston preses the lubricating oll stored in thelower chamber to the upper chamber throuah the small hole of the core rod. , and the next fuel supply is also ready.
