Check valve with hydraulic damping system

A check valve for use in a pressurized fluid line providing an adjustable closure rate, said check valve comprising:

• a second cylindrical body formed from a continuous sidewall having an inner diameter, an outer diameter, a first end and a second end, said second cylindrical body centrally positioned within said first cylindrical body;
• a piston slidably disposed within said second cylindrical body having a first end and a second end;
• a sealing disk attached to said first end of said piston, said sealing disk sized to seal said inlet opening;
• a biasing means for biasing said sealing disk against said inlet opening;
• a servant check valve disposed within said second end of said second cylindrical body, said servant check valve oriented to allow fluid flow into said second cylindrical body;
• a seal ring secured to said second cylindrical body, said seal ring having an inner diameter operatively associated with said piston;
• a valve needle extending from a threaded bore disposed in said side wall of said first cylindrical housing to an aperture disposed in said side wall of said second cylindrical housing, said valve needle having a threaded first valve needle end and a second valve needle end, said first valve needle end shaped to engage said threaded bore, said second valve needle end having an second valve needle end, said first valve needle end shaped to engage said threaded bore, said second valve needle end having an insertion end operatively associated with said aperture of said second cylindrical housing;
• a plurality of braces extending between an inner surface of said first cylindrical body and an outer surface of said second cylindrical body.
