Abstract
The damper for pressure measuring systems is integrated in the body (5) or insert of a valve. Flow passages (6, 7) communicate with a compartment (9) which is sealed by a rubber-elastic diaphragm (10). The side of the diaphragm remote from said compartment (9) defines a second compartment (13) which is connected to atmosphere through a port (14) designed to provide flow resistance.
