Abstract
The microvalve comprises a drive housing ( ) in which a magnetic drive is arranged that includes a solenoid ( ) and an armature ( ) adapted to be actuated by the solenoid. A flanged housing ( ) in which two valve seats ( ) are formed is mounted against the drive housing. Arranged between the drive housing ( ) and the flanged housing ( ) is a diaphragm ( ) which is adapted to be pressed against the valve seats by means of a commutation rocker ( ) coupled to the armature. The commutation rocker ( ) has a pivot bearing, the axis ( ) of which, for avoiding tolerances, assumes a position which is determined by direct abutment on a seating surface of the flanged housing ( ) facing the drive housing ( ).
