ELECTRONIC LUBE GUN WITH LOW BATTERY PROTECTION |
摘要 |
A device for delivering a preset volume of fluid, such as oil, includes a casing (10) with an inlet port (16), an outlet port (17) and supply passages (22, 24) for flow of fluid from the inlet port (16) to the outlet port (17). A valve including a valve member (24) is situated to control the flow of the fluid through a valve chamber (23). The valve is manually actuated to an open position and held by momentary energization of a latching solenoid (36). When the fluid volume reaches a preset volume, the latching solenoid (36) is energized again to allow the release the valve member (24) to return to a closed position. In the event of a battery low condition, the latching solenoid (36) 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 botton (21) is directly connected to the valve member (24) for closing the valve manually. A method for controlling the dispensing of a fluid is also disclosed. |
