Ventile mit Schwingspulenmotor und Wärmeableitung

摘要

An electromechanical valve that includes a cylindrical housing having a first axially disposed chamber containing a valve body and a spool reciprocally mounted in the body for movement along the axis of the housing. A second chamber is located within the housing adjacent to the first chamber which contains a voice coil actuator having a coil holder that is coupled to the spool so that the spool moves linearly when a current is applied to the coil. Materials having a high thermal conductivity are placed in the voice coil actuator for rapidly transmitting heat energy generated in the coil to the housing so that the energy is dissipated into the surrounding ambient before it can damage the actuator.
