Abstract

A servo operated spool valve having a fixed sleeve and axially movable spool. The sleeve is machined in two halves to form a long, narrow tapered orifice slot across which a transverse wall of the spool is positioned. The axial position of the spool wall along the slot regulates the open orifice area with extreme precision.

Hydraulically actuated fuel injector including a pilot operated spool valve assembly and hydraulic system using same

Patent Shafer, Scott F [Morton, IL]

The present invention relates to hydraulic systems including hydraulically actuated fuel injectors that have a pilot operated spool valve assembly. One class of hydraulically actuated fuel injectors includes a solenoid driven pilot valve that controls the initiation of the injection event. However, during cold start conditions, hydraulic fluid, typically engine lubricating oil, is particularly viscous and is often difficult to displace through the relatively small drain path that is defined past the pilot valve member. Because the spool valve typically responds slower than expected during cold start due to the difficulty in displacing the relatively viscous oil, accurate start ofmore » « less

Valve actuator assembly having a center biased spool valve with detent feature

Patent Marriott, Craig D.; Sun, Zongxuan

A valve actuator assembly for an engine includes a movable poppet valve, and movable first and second spool valves. The assembly also includes an intermediate channel interconnecting the first and second spool valve, a driving channel, and a first and second feedback channel interconnecting the second spool valve and the poppet valve. The valve actuator assembly includes an actuator cooperating with the first spool valve to position the first spool valve to selectively allow high pressure fluid flow to the second spool valve and the driving channel to position the engine valve. The valve actuator assembly further includes a firstmore » « less

System and method for controlling hydraulic pressure in electro-hydraulic valve actuation systems

Patent Brennan, Daniel G; Marriott, Craig D; Cowgill, Joel; ...

A control system for an engine includes a first lift control module and a second lift control module. The first lift control module increases lift of M valves of the engine to a predetermined valve lift during a period before disabling or re-enabling N valves of the engine. The second lift control module decreases the lift of the M valves to a desired valve lift during a period after enabling or re-enabling the N valves of the engine, wherein N and M are integers greater than or equal to one.

Hydraulic engine valve actuation system including independent feedback control

Patent Marriott, Craig D

A hydraulic valve actuation assembly may include a housing, a piston, a supply control valve, a closing control valve, and an opening control valve. The housing may define a first fluid chamber, a second fluid chamber, and a third fluid chamber. The piston may be axially secured to an engine valve and located within the first, second and third fluid chambers. The supply control valve may control a hydraulic fluid supply to the piston. The closing control valve may be located between the supply control valve and the second fluid chamber and may control fluid flow from the second fluidmore » « less
