Pump for gaseous and liquid medium, has pump membrane and valve plate that is confined with pump chamber, where membrane has disk-shaped flat form spring that is wrapped by elastomeric cladding, which fills gaps between spring bars

摘要

The pump has a pump membrane (23) and a valve plate (24), which are arranged at a distance. The valve plate confines with a pump chamber (21) in a casing. The pump membrane is assigned to a plate anchor (30) that is movable over a magnetic head. The pump membrane has a thin, disk-shaped flat form spring (25) that is wrapped by an elastomeric cladding (26), where the cladding fills gaps between spring bars.
