LUBRICATION SYSTEM REPLENISHMENT AUTOMATIC SHUTTING OFF Russian patent published in 2018 - IPC F01M11/06 F01M11/04 

FIELD: machine building.

SUBSTANCE: invention relates to the automatic replenishment shut off subsystem for the mobile lubrication system. Lubrication system comprises the lubricant tank, inlet port to the lubricant tank, the diaphragm plate, locking pin, replenishment inlet port, replenishment outlet port and the shut off valve. Diaphragm plate is located in the highest position in the lubricant tank. Locking pin is connected to the diaphragm plate so, that the lubricant tank filling-up moves the locking pin from the first position into the second position. Replenishment inlet port is adapted to receive lubricant, and the replenishment outlet port is fluidly connected to the lubricant tank inlet port. Shut off valve is connected between the replenishment inlet port and the replenishment outlet port, and is actuated by the locking pin so, that to fluidly connect the replenishment inlet port and the replenishment outlet port, when the locking pin is in the first position, and to fluidly isolate the replenishment inlet port from the replenishment outlet port when the locking pin is in the second position.

EFFECT: invention enables increase in the lubricant amount to protect against wear, corrosion prevention and frictional heating reduction.
