Abstract

Pompa a membrana atta per fluidi contenenti gas, in cui la camera del fluido da pompare è a forma tronco-conica analogamente alla membrana elastica la quale è connessa con il suo bordo di minor diametro con un piattello centrale rigido provvisto alla sua periferia di una superficie tronco-conica di appoggio per la sottostante membrana. Sono inoltre previste protezioni per la membrana elastica.
