Abstract
A pressurized oil injection pre-lubrication system for an oil gallery in an engine block of an engine in a motor vehicle comprising a pressure accumulator and a normally closed electromagnetic valve. A component is for fluidly connecting the pressure accumulator to the electromagnetic valve. Another component is for fluidly connecting the electromagnetic valve to the oil gallery in the engine block. An ignition switch is electrically connected to the electromagnetic valve. When the ignition switch is turned to an on position, the electromagnetic valve will open to allow oil from the pressure accumulator to flow into the oil gallery in the engine block, before the ignition switch is turned to a start position to start the engine in the motor vehicle.
Claims5
A pressurized oil injection pre-lubrication system for an oil gallery in an engine block of an engine in a motor vehicle comprising:
- a) a pressure accumulator, said pressure accumulator including a storage tank, and a flexible wall within said storage tank for dividing said storage tank into two compartments, in which the first compartment is for holding pressurized gas therein, while the second compartment is for holding the oil therein, said storage tank including a first shell section with the first compartment and having an annular flange thereabout, a second shell section with the second compartment and having an annular flange thereabout, and a plurality of bolts for securing said annular flanges together, said flexible wall being a diaphragm having its circumference sealed between said annular flanges to separate the pressurized gas from the oil;
- b) a normally closed electromagnetic valve;
- c) means for fluidly connecting said pressure accumulator to said electromagnetic valve;
- d) means for fluidly connecting said electromagnetic valve to the oil gallery in the engine block;
- e) an ignition switch electrically connected to said electromagnetic valve, so that when said ignition switch is turned to an on position, said electromagnetic valve will open to allow oil from said pressure accumulator to flow into the oil gallery in the engine block, before said ignition switch is turned to a start position to start the engine in the motor vehicle;
- f) an annular mounting bracket connected to said first shell section, said mounting bracket having a plurality of holes thereabout, so that it can be affixed to a fire wall in the motor vehicle with a plurality of bolts;
- g) a gas injection valve in said first shell section, sot allow gas to enter said first shell section;
- and
- h) an air bleeder valve in said second shell section, to allow air to exit said second shell section.
