ABSTRACT:
The non-return valve comprises a housing provided with an inlet connection, a coaxial installation opening, and an outlet connection. An insert is secured in the installation opening to define a chamber with a cover on the valve. A movable valve body means includes a piston which divides the insert chamber into two cylindrical chambers while connecting ducts lead from the respective cylinder chambers to the housing chamber on the outlet side. A damping member is provided on the movable valve body system in the form of an annular ring to penetrate into the duct leading from the lower cylinder chamber when the valve closes to bring about a throttling action. Shock-like closure of the valve is thus eliminated in a simple and operationally reliably manner.
