Abstract
A device for delivering a preset volume of fluid, such as oil, includes a casing ( ) with an inlet port ( ), an outlet port ( ) and supply passages ( ) for flow of fluid from the inlet port ( ) to the outlet port ( ). A valve including a valve member ( ) is situated to control the flow of the fluid through a valve chamber ( ). The valve is manually actuated to an open position and held by momentary energization of a latching solenoid ( ). When the fluid volume reaches a preset volume, the latching solenoid ( ) is energized again to allow the release the valve member ( ) to return to a closed position. In the event of a battery low condition, the latching solenoid ( ) can be disabled, so that the valve can only be held open manually, thereby preventing an electrical failure with the valve open. A manual push button ( ) is directly connected to the valve member ( ) for closing the valve manually. A method for controlling the dispensing of a fluid is also disclosed.
