Abstract
A variable flow valve is provided. The variable flow valve includes a housing, an actuator, a biasing agent, positioning coils, and a locking coil. The housing defines a bore, an inlet, and an outlet. The actuator is moveably disposed within the bore and configured to selectively obstruct and expose the outlet. The biasing agent is disposed within the bore. The biasing agent is also interposed between the housing and the actuator to bias the actuator toward the outlet. The positioning coils are disposed about the housing and operable to drive the biasing agent to a retracted position. The locking coil is disposed about the housing proximate the biasing agent. The locking coil is operable to capture the biasing agent in the retracted position. As such, the positioning coils are thereafter able to move the actuator free of the bias from the biasing agent.
