Quick impulse valve with electromagnetic drive - comprises profiled and-or pierced membrane spring with deformation-rigid centre, with edge of spring being securely located in housing, tubular connecting piece being symmetrical to centre in base of housing

摘要

The valve comprises a profiled and/or pierced membrane spring (5) with a deformation-rigid centre. The edge of the spring is securely located in a housing (1). A tubular connecting piece (7) is arranged symmetrical to the centre in the base (3) of the housing and inside the inclining section of the membrane spring. The outer diameter of the connecting piece is smaller than the housing and is arranged to the centre such that a variable pressure surface is available. The inner diameter and the opening of the connecting piece is smaller than the deformation-rigid centre. The connecting piece is connected at the other end with an inlet connecting piece (8). An outlet connecting piece (9) which is fixed to the housing, has the same shape as the inlet connecting piece and is spatially separated from it. The valve has an electromagnetic drive (14) and the profiled membrane spring simultaneously acts as the drive anchor.
