Abstract
Disclosed is a reed valve which uses a simple electromechanical actuator to apply a force that overcomes pressure force and opens the valve. The valve is closed by pressure and the elastic restoring force of the reed. Two of the disclosed valves in a back-to-back connection accommodate bi-directional flow. The disclosed valve is especially suited for application as a pulsed expansion valve for refrigerators and heat pumps.
