Latest Patents

One of her latest inventions is the "Engine Air Shut-Off Valve System." This system features a housing, a gate member, a rotating lever, a locking piston assembly, and a closing piston assembly. It is designed to be installed in fluid connection with a flow line, allowing air flow to pass through a passageway in the housing when the gate member is in the locked configuration. The air flow ceases when the gate member is closed. The unique asymmetry of the gate member ensures that the forces from the springs of both the closing and locking piston assemblies work together to transition between the closed and locked configurations, thereby extending the valve system's lifespan. Additionally, both the closing and locking piston assemblies are easily accessible for maintenance.

Another notable patent is the "Accumulator Over Hydraulic Pump Double-Acting Cylinder for Artificial Lift Operations." This artificial lift system is designed for subterranean wells and includes a cylinder with a reciprocating piston. The piston has two sides, one of which can be selectively connected to a hydraulic pressure source and a hydraulic reservoir, while the other side connects to the hydraulic pressure source and at least one accumulator. This innovative design allows for efficient control of hydraulic pressure applied to the pump from the accumulator.
