Abstract

The valve housing (10) has a sleeve (20) and a pressure transfer unit (30). The housing has a flange (11) with an inlet (12) and a second flange (13) on an exit (14). The housing body is made from an elastomeric material whose tube area (24) in the undeformed condition is defined by a tube-shaped pipe connector (19) which lies between the inlet and the outlet and is under pressure from a working fluid which flows thorough it.
