Reinforcing means for diaphragms Patent

Reinforcing beam system for highly flexible diaphragms in valves or pressure switche

High pressure regulator valve Patent

Structural design of high pressure regulator valv

Surface treatment for valve seats

Valve with embedded fine particles of diamond in the metal surface of the valve seat resists galling, corrosion, erosion, and cold welding. Diamond powder has an average particle diameter of 0.01 micron and is used with a standard fine diamond polishing compound

Multiple Belleville spring assembly Patent

Multiple Belleville spring assembly with even load distributio

Embossed metal diaphragm has two-way stretch

Diaphragm with embossed pattern has greater structural rigidity than one with smooth surfaces, but under severe stress, tensile loads will flatten embossing. This provides necessary additional panel stretch needed to prevent rupture of diaphragm material. Hexagonal embossing-configuration allows panel stretch in any direction or in all directions simultaneously

Filler valve Patent

Filler valve design for supplying liquid propellants at high pressure to space vehicle

Pressure regulating system Patent

Pressure regulating system with high pressure fluid source, adapted to maintain constant downstream pressur

High pressure four-way valve Patent

High pressure four-way valve with O ring adapted to pass across inlet por

Belleville spring assembly with elastic guides

Belleville spring assembly with elastic guides having low hysteresi
