Abstract
The microvalve comprises a drive housing (3) in which a magnetic drive is arranged that includes a solenoid (1) and an armature (6) adapted to be actuated by the solenoid. A flanged housing (2) in which two valve seats (10a, 10b) are formed is mounted against the drive housing. Arranged between the drive housing (3) and the flanged housing (2) is a diaphragm (5) which is adapted to be pressed against the valve seats by means of a commutation rocker (4) coupled to the armature. The commutation rocker (4) has a pivot bearing, the axis (13) of which, for avoiding tolerances, assumes a position which is determined by direct abutment on a seating surface of the flanged housing (2) facing the drive housing (3).
