Abstract

In some embodiments, a fluid dynamics system includes a solenoid valve including a valve body including ports including an inlet port and an outlet port, and a valve cavity having a direction of elongation and configured to provide fluid connectivity between respective ones of the ports, a solenoid coil disposed in the valve body around valve cavity, and a plunger comprising a permanent magnet, and configured to move back-and-forth along the direction of elongation between a first position and a second position in the valve cavity selectively controlling the fluid connectivity between respective ones of the ports, and a controller configured to apply at least one current to the solenoid coil to selectively move the plunger between the first position and the second position, and to selectively maintain the plunger in the first position and the second position.
