摘要： An internal combustion engine of the valve-in-head type having a low profile cylinder head which requires minimal headroom in the engine compartment of an automotive vehicle. The cylinder head has a rectilinear configuration with the valve trains disposed on horizontal axes extending transversely of the cylinder head. Each valve train in the cylinder head is provided with precise axial support at both ends of the train. The engine has a relatively thin upstanding combustion chamber over each cylinder and one or more pairs of poppet valves per cylinder each having a sealing surface adjacent its outer edge for engagement with respective seats defined by axially aligned header tubes. Each valve has a relatively short neck extending through the combustion chamber during the intake and compression strokes and when the fuel-air mixture is fired. The valve spring of each valve train is situated between a fixed abutment attached to the side wall of the cylinder head and the end of the valve cage remote from the poppet valves.

摘要： The exhaust valve has a valve member which opens away from the combustion chamber of the engine cylinder and which is biased for opening by the gas pressure prevailing in the combustion chamber. The valve is kept closed by an opposed hydraulic pressure which in a holding chamber acts on a holding piston secured to the spindle of the valve member. When the valve is to be opened, the pressure in the holding chamber is relieved and one or more valve controlled flow passages are opened, through which hydraulic liquid flows from the holding chamber to a reservoir defined by a further piston secured to the valve spindle. The two pistons are preferably of substantially equal size. When the exhaust valve is to be closed a hydraulic pressure is applied to a substantially smaller closing piston which is also secured to the valve spindle. During the closing movement hydraulic liquid flows from the reservoir back to the holding chamber and after the closing movement that chamber is again connected to the hydraulic pressure which ensures that the valve member is maintained in its closed position against the gas pressure.

摘要： An active chamber engine, includes at least one piston (2) slidingly mounted in a cylinder (1) and operating according to a three-phase thermodynamic cycle including an isobaric and isothermal transfer, a polytropic expansion with work and an exhaust at ambient pressure, which is preferably supplied with compressed air contained in a high-pressure storage tank (12), in which the volume of the cylinder (1) swept by the piston is divided into an active chamber (CA) and an expansion chamber (CD), and in which the compressed air is used to move the intake valve (9) in order to open and then close the intake duct, making it possible to supply the active chamber of the engine, the compressed air having been used for the actions then being reused in the engine to produce additional work.

摘要： A valve for a marine propulsion unit comprises a valve body (11) having an end face (13) and a wall (14) extending from the end face. An aperture (15) is defined in the end face. A valve stem (12) is moveable within and with respect to the valve body, such that, in the closed state of the valve, the valve stem closes the aperture. A maximum width (d1) of the valve stem is greater than the width (d2) of the aperture in the end face of the valve—so that, if the valve stem should fracture, the detached portion(s) of the valve stem will be retained in the valve body. The valve may for example be used as a cylinder drain valve in a marine propulsion unit.

摘要： Embodiments relate generally to energy storage systems, and in particular to energy storage systems using compressed gas as an energy storage medium. In various embodiments, a compressed gas storage system may include a plurality of stages to convert energy into compressed gas for storage, and then to recover that stored energy by gas expansion. In certain embodiments, a stage may comprise a reversible compressor/expander having a reciprocating piston. Pump designs for introducing liquid for heat exchange with the gas, are described. Gas flow valves featuring shroud and/or curtain portions, are also described.

摘要： Valve actuation systems are disclosed herein that allow valve opening timing to be varied using a cam phaser and that allow valve closing timing to be varied using a lost-motion system. In one embodiment, an actuation system is provided that has a locked configuration in which a bearing element is held in place between a cam and a rocker to transmit cam motion to an engine valve. The actuation system also has an unlocked configuration in which the bearing element is permitted to be at least partially ejected from between the cam and rocker, such that cam motion is not transmitted to the engine valve. The actuation system is switched to the unlocked configuration by draining fluid therefrom through a main valve which is piloted by a trigger valve. The actuation system also includes integrated autolash and seating control functionality.

摘要： Devices and related methods are disclosed that generally involve the selective deactivation of one or more engine valves. In one embodiment, a split-cycle internal combustion engine is provided in which a high-speed trigger valve is used to fill and drain a hydraulic tappet that forms part of a lost-motion system of an engine valve. A spool valve can be used to selectively disconnect the tappet from the trigger valve, thereby deactivating the associated engine valve (i.e., preventing the engine valve from opening). The devices and methods disclosed herein also have application in conventional internal combustion engines and can be used with inwardly-opening and/or outwardly-opening valves.
