摘要： A camless valve assembly for an internal combustion engine which utilizes a plurality of three position control valves to open and close the intake and exhaust valves of the assembly. Each valve is coupled to a plurality of hydraulically driven pins that move the valve between the open and closed positions. The flow of fluid to the pins is controlled by the three position digitally latched solenoid actuated control valves that can be switched between a first position, a second position and a neutral position. When a control valve is in the first position the fluid flows into the pins and moves the valve. When the control valve is in the second position the fluid can flow away from the pins to allow the valve to move back to the original position. When the control valve is in the neutral position the fluid does not flow so that the valve cannot move. The control valve can be switched by a controller that can move and maintain a valve at any position during any cycle of the engine.

摘要： A control apparatus for a solenoid-operated valve that functions as an intake or exhaust valve of an internal combustion engine includes a lower spring (30) biasing a valve body (14) of the valve in a valve closing direction and upper and lower coils (42, 46) disposed above and below an armature (36) for generating electromagnetic forces to move the valve body (14) in the valve closing and valve opening directions. After a request for closing of the valve body (14) is made, command currents are supplied to the upper and lower coils (42, 46) in suitable timing to increase the speed at which the valve body (14) is seated against a valve seat (20). As the valve body (14) rotates about its axis due to the action of the lower spring (30) in the course of moving toward the valve seat (20), it is possible to crush and remove carbon between the valve body (14) and the valve seat (20) without causing local wear of the valve body (14).

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： A gas exchange valve arrangement for a supercharged internal combustion engine, which arrangement comprises a gas exchange valve (1) having a valve head (2) and a valve stem (3) connected to the valve head (2), the arrangement further comprising a valve spring (4) being arranged around the valve stem (3) for creating a force for closing the valve (1), a chamber (5) being arranged around the valve stem (3), and thrust means (6, 19) being attached to the valve stem (3) and being movable in the direction of the longitudinal axis of the valve stem (3) together with the gas exchange valve (1). The arrangement comprises means (7, 14) for introducing pressurized charge from an air intake duct (10) of the engine air into the chamber (5) between the thrust means (6, 19) and the inner end of the chamber (5) for assisting in keeping the valve (1) closed. The invention also concerns a cylinder head (9).
