Measured shot ether system
First Claim
1. An automatic measures shot starting fluid assembly for injecting a predetermined amount of starting fluid into a passageway of an engine, said assembly comprising:
- a power source to supply electrical current;
starter motor means connected to said power source for engaging and rotating the crankshaft of the engine upon being energized by receiving electrical current from said power source;
ignition switch means interconnecting said power source and said starter motor means for allowing electrical current to flow to said starter motor means upon closing said switch means for energizing the starter motor;
container means for containing and supplying starting fluid;
fluid atomizing means disposed in the passageway of the engine for atomizing the starting fluid from said container means into the passageway;
valve means connected to said container means for measuring a predetermined amount of starting fluid from said container means and injecting the measured amount of starting fluid to said atomizing means;
conduit means interconnecting said valve means and said atomizing means for providing a passageway to allow the starting fluid to flow to said atomizing means; and
control circuit means, responsive to the ignition switch means being closed and the starter motor being energized, for activating said valve means for a first predetermined timed interval and then deactivating the valve means for a second predetermined time interval;
said valve means being activated and deactivated for said first and second time intervals for so long as the ignition switch means is energizing the starter motor whereby measured shots of starting fluid are injected into the engine in a uniform manner while being minimally affected by operator intervention.

Abstract
An automatic measured shot starting fluid assembly (10) injects a predetermined amount of starting fluid into a passageway (11) of a diesel engine. The assembly includes a power source (12) to supply electrical current and a starter motor (14) and solenoid (16) for engaging and rotating the crankshaft of the engine upon receiving electrical current from the power source (12). An ignition switch (18) interconnects the power source (12) and the starter motor solenoid (16) for allowing electrical current to flow upon closing the ignition switch (18). An atomizer (30) is disposed in the passageway (11) of the engine for atomizing the starting fluid into the passageway (11). A measured shot valve (26) is connected to a fluid cylinder (24) for measuring a predetermined amount of starting fluid from the fluid cylinder (24) and injecting the measured amount of starting fluid through a conduit (28) to the atomizer (30). A control circuit (32) interconnects the solenoid (16) and the measured shot valve (26) for allowing current to flow from the starter solenoid (16) to the measured shot valve (26) for a first predetermined interval of time to measure a predetermined amount of starting fluid. The control circuit (32) also prevents current from flowing to the measured shot valve (26) for a second predetermined interval of time between successive measured shots of starting fluid continuously upon closing of the ignition switch (18).
