Latest Patents
One of John Sears' latest patents is the "Fluid Intensifier for a Dry Gas Seal System." This innovative gas supply system activates at a pressurized flow rate during compressor case pressurization and remains operational throughout compressor rotation until adequate pressure is achieved. The system features an intensifier composed of mechanically inter-connected pneumatic pressure cylinders, which enhance the pressure discharged by the boost cylinder, supplying barrier fluid to the mechanical seal. The design incorporates a control valve and an operating system that utilizes a fast-acting 5/2-way solenoid valve, complete with a feedback loop connected to a microprocessor for precise valve actuation.
Another significant patent is the "Seal Leakage Gas Recovery System." This system effectively collects seal leakage gas from mechanical seal assemblies, managing the outlet distribution pressure of the collected gas and re-injecting it back into the compressor or seal supply system. This innovation not only improves efficiency but also contributes to environmental sustainability by minimizing gas waste.
