Methods and devices relating to hydraulic valves and switches

This invention describes a fluidic switch that uses a magnetic piston moving within a non-magnetic sleeve. An electrical coil surrounding the sleeve generates a magnetic field to push or pull the piston, controlling fluid flow. The design includes specific non-magnetic washers and plates, with the washer's thickness influencing how strongly the piston is held in place.

Why it matters: Advancements in micro-actuator efficiency and battery energy density since 2017 make compact, low-power fluidic systems more practical for portable devices. This enables the low footprint and power consumption targeted by the invention.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: ModerateCustom magnetic piston, non-magnetic sleeve, electrical coil
