    Abstract: Embodiments relate to valves comprising a member such as a plate or poppet, that is moveable relative to a stationary seat. The state of the member may be maintained against opposing forces with relatively little expenditure of energy. According to one embodiment, a poppet displaced from seating in the valve seat, may be held in position against opposing forces tending to close the valve, until a desired flow of gas through the valve has taken place. The poppet may then be released as desired, such that those opposing forces serve to passively close the valve. The valve may be secured in position utilizing mechanical, magnetic, electromagnetic, pneumatic, electrostatic, or hydraulic approaches. Valve embodiments may be particularly suited to controlling gas flows for compression and/or expansion in an energy storage system.

    Abstract: An opposed piston engine includes a valve mechanism for regulating fluid flow through an opening formed in a cylinder of the engine. The mechanism includes a valve operatively coupled to the cylinder so as to be rotatable to a first position to seal the opening and to a second position to unseal the opening, and at least one cam surface operatively coupled to the cylinder so as to be movable with respect to the cylinder to engage the valve so as to produce rotation of the valve.

    Abstract: A two-cycle dry-sump fuel-injected engine includes a cylinder block with piston bores that step up substantially in diameter between the top of each cylinder and the bottom. A matching piston similarly steps in its outside diameter with a larger diameter lower skirt having an oil seal ring. A narrower diameter of the piston involves the top better part of its length. A jacket chamber all around the piston changes in volume as the piston travels. A combustion chamber has an exhaust valve and a fuel injector. The jacket chamber provides a pump for an oil mist and air lubrication system. Fresh air is drawn into the crankcase. When the piston moves all the way down, the fresh air is compressed by the larger displacement volume of the larger diameter piston skirt and transferred through to a smaller displacement volume of the upper piston to completely scavenge the exhaust.

    Abstract: A cylinder head (3) for an axial flow rotary valve (1). The head comprises a bore (2) having an axis and adapted to house an axial flow rotary valve (1), a window (8) in the bore through which at least one port (12, 13) in the valve periodically communicates with a combustion chamber (9) as the valve rotates, at least two axially extending slots (21) in the bore, adjacent opposite sides of the window, each of the slots being adapted to locate a floating elongate gas sealing element (20), and at least one spark plug hole (7) adjacent to the bore and adapted for mounting a spark plug associated with the valve. The head further comprises at least one elongate axially extending cooling passage (24, 25 26) disposed between the bore and the spark plug hole, adjacent to one of the slots, the passage having a substantially constant cross section and extending axially at least over the length of the slots.

    Abstract: A valve unit for an internal combustion engine includes a duct, a valve and a shaft. The duct includes an inner tube defining a gas passage and an outer tube disposed radially outside of the inner tube. The duct has an annular liquid storage groove between the outer tube and the inner tube. The valve is supported by the shaft in the inner tube to control the gas passage The shaft is held by a bearing portion of the duct. The inner tube has an overflow portion and an overflow-restricting portion at an upper end. The overflow portion regulates a level of liquid stored in the storage groove and allows excess liquid to overflow from the storage groove. The overflow-restricting portion is provided in a predetermined area above the bearing portion and located higher than the overflow portion to restrict the liquid from overflowing from the predetermined area.
