1. A lubrication fluid reservoir apparatus for a vehicle engine, comprising:
a. a substantially rectangular sump plate adapted for attachment to a base of the vehicle engine, the sump plate having a front end and an opposing rear end, a first side and an opposing second side, a floor, and a perimeter wall, the sump plate adapted to store lubrication fluid;
b. a first tunnel port formed along the sump plate floor, the first tunnel port having a first opening at the first side of the sump plate and a second opening at a central area of the sump plate, wherein the first tunnel port first and second openings are in fluid communication with each other through the first tunnel port;
c. a second tunnel port formed along the sump plate floor, the second tunnel port having a first opening at the second side of the sump plate and a second opening at the central area of the sump plate, wherein the second tunnel port first and second openings are in fluid communication with each other through the second tunnel port;
d. a valve body mounted above the first tunnel port second opening and the second tunnel port second opening, the valve body having a first chamber in fluid communication with the first tunnel port second opening, a second chamber in fluid communication with the second tunnel port second opening, a central chamber in fluid communication with the first and second chambers, and a top opening in communication with the central chamber for receiving a lubrication fluid take-up tube;
e. a valve shaft slidably mounted within the valve body, the valve shaft having a first end extending out of a first side of the valve body and a second end extending out of a second side of the valve body;
f. a first weighted roller mounted to the valve shaft first end and a second weighted roller mounted to the valve shaft second end, wherein the first and second weighted rollers are adapted to move the valve shaft within the valve body in response to G-force acting upon the first and second weighted rollers;
g. a fin attached to the valve shaft external of the valve body, wherein the fin is adapted to move the valve shaft within the valve body in response to lubrication fluid pushing against the fin in response to G-force acting upon the lubrication fluid;
h. a first baffle mounted between the first tunnel port first opening and the valve body, the first baffle having at least one opening covered by a one-way flap, the first baffle adapted to maintain lubrication fluid at the first tunnel port first opening;
i. a first deaerator hood mounted across a substantial portion of the first baffle and comprising a downwardly sloped upper surface extending towards the sump plate first side, the first deaerator hood adapted to prevent agitation of lubrication a fluid in area between the first baffle and the sump plate first side;
j. a second baffle mounted between the second tunnel port first opening and the valve body, the second baffle having at least one opening covered by a one-way flap, the second baffle adapted to maintain lubrication fluid at the second tunnel port first opening; and
k. a second deaerator hood mounted to the second baffle and extending towards the sump plate second side, the second deaerator hood adapted to prevent agitation of a lubrication fluid in area between the second baffle and the sump plate second side;
l. wherein the valve shaft is operable to slide between a first open position and a second open position, wherein the first tunnel port first opening is in fluid communication with the central chamber through the first chamber when the valve shaft is in the first open position, wherein the second tunnel port first opening is blocked from fluid communication with the central chamber through the second chamber when the valve shaft is in the first open position, wherein the second tunnel port first opening is in fluid communication with the central chamber through the second chamber when the valve shaft is in the second open position, wherein the first tunnel port first opening is blocked from fluid communication with the central chamber through the first chamber when the valve shaft is in the second open position;
m. wherein the lubrication fluid take-up tube is adapted to withdraw lubrication fluid from the valve body central chamber through the valve body top opening.
