Filed:

Aug 21, 2000

Appl. No.:

09/643148

Inventors:

Oded E. Sturman - Woodland Park CO
Steven Massey - Woodland Park CO

Assignee:

Sturman Industries, Inc. - Woodland Park CO

International Classification:

F15B 13044

US Classification:

137 1, 13762565

Abstract:

A three position digitally latched actuator actuated fluid control valve. The control valve includes a housing which has a cylinder port, a supply port and a return port. The control valve also contains an internal valve that moves between a first position, a second position and a neutral position. In the first position the internal valve provides fluid communication between the cylinder port and the supply port. In the second position the valve provides fluid communication between the cylinder port and the return port. In the neutral position the valve prevents fluid communication between the ports. The control valve has a first actuator and a second actuator that are actuated by digital pulses to move the internal valve between the first, second and neutral positions. The control valve may have a pair of springs that bias the internal valve to the neutral position, wherein the actuator can be actuated to latch the valve into the first position and the second actuator can be actuated to latch the valve into the second position.

International Classification:

F02B 71/00

US Classification:

123 46R, 123 46 SC

Abstract:

Hydraulic internal combustion engines having at least one combustion piston not mechanically connected to a crankshaft or any other combustion piston, but instead acting on hydraulic plungers through valving that is electronically controlled to control the piston position and velocity, typically through an intake stroke, a compression stroke, a combustion or power stroke and an exhaust stroke. Electronically controlled fuel injection and electronically controlled engine valves provided great flexibility in the operating cycles that may be used, with the engine pumping hydraulic fluid to a high pressure accumulator for use in hydraulic motors or other hydraulic equipment. Embodiments using high pressure air injection to sustain combustion are also disclosed.

Assignee:

Sturman Digital Systems, LLC - Woodland Park CO

International Classification:

H01F 7/10

US Classification:

335250

Abstract:

Actuators with printed actuator coils facilitate efficient manufacturing and reliable operation. The printed actuator coils are in coil segments on multiple layers on a multilayer printed circuit board, which may contain a printed actuator coil for one or more additional actuators, and/or electronic circuitry, such, as may be used for control of the actuator(s).

International Classification:

F15B 13/044

US Classification:

137625650

Abstract:

Pressure balanced spool poppet valves with printed actuator coils minimize valve leakage and facilitate efficient manufacturing and reliable operation. The spool poppet valves may be configured like a conventional spool valve, but further include a poppet valve at one end of the spool to proved much better sealing when the poppet valve is closed. Various features are disclosed, including pressure balancing for high pressure operation. The printed actuator coils for the spool poppet valves are formed by the interconnection of conductive coils on each of multiple layers of a multiple layer printed circuit board, which circuit board may have a hole there through for accommodation of mechanical and/or magnet requirements, and may include similar printed actuator coils for one or more additional spool poppet valves as well as electronic devices associated with the operation thereof. The spool poppet valves may be advantageously constructed without printed actuator coils, and the printed actuator coils may be advantageously used in actuators of other designs.
