Improving Oil Change Efficiency with Solenoids
This latching solenoid provided precise control over the amount of oil dispensed by an oil dispensing meter without any waste.
A manufacturer of fluid handling systems needed a solution for an automatic shut-off feature on an oil dispensing meter. The meter’s high pressure and flow made it difficult to control manually, often resulting in spills. The manufacturer’s goal was to develop a product that would dispense a precise amount of oil without any spillage or waste. The solution also needed to be battery operated and compact.
The TLX Solution
TLX Technologies designed a custom latching solenoid that used a permanent magnet to hold the oil dispensing meter’s valve open without consuming any power. When the meter determined that the correct amount of oil had been dispensed, a short voltage pulse canceled the magnetic field of the permanent magnet, and a spring closed the valve and stopped the flow of oil. The solenoid could operate efficiently for six months on four AA batteries.
