초록

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 ...

1. A voice coil operated valve that includes:a housing having a first chamber that contains a valve sleeve and a valve spool mounted for reciprocal movement within the sleeve along a central axis of the housing; said housing further containing a second chamber located adjacent said first chamber; a linear voice coil actuator mounted within said second chamber that contains a stationary permanent magnet and a coil holder for movably supporting a coil within the magnetic field of said magnet whereby said holder moves along the axis of the housing when a cu...
