Latest Patents

One of Edward's latest patents is for a *Variable Lost Motion Valve Actuator and Method*. This invention presents a sophisticated engine valve actuation system that includes a valve train element, a pivoting lever, a control piston, and a hydraulic circuit. The design features a pivoting lever with a first end that contacts the control piston and a second end that transmits motion to a valve stem, in addition to mechanisms for interacting with the valve train element. The clever design allows for the selection of lost motion provided by the system by adjusting the control piston relative to the pivoting lever. Furthermore, the control piston can be hydraulically connected to a control trigger valve and accumulators to modify the loss motion. This innovation also includes features for limiting valve seating velocity, ensuring the hydraulic circuit is filled upon engine startup, and a mechanism for mechanically locking the control piston and lever for fixed valve actuation levels.
