An electromagnetically bistable changeover valve for a refrigeration circuit has the coil positioned alongside the axis of the magnetic poles.

摘要

The valve (1) comprises an electromagnetic coil (24) and armature (16) within a tube (3) which has outlets (11,12) and an inlet (14), valve seats (21,22) in pole pieces (6,7) and spherical closures (19,20). Permanent magnets lie each side alongside the valve armature tube.
