    Abstract: PURPOSE:To thermally deform a valve seat part in an axis of symmetry and prevent a blow-by in the seat part, by providing a unified valve used in common for intake and exhaust in the center of a cylinder cover while a control valve respectively in intake and exhaust passages communicating with the unified valve. CONSTITUTION:A port used in common for intake and exhaust is formed in the center of a cylinder cover, being opened and closed by a unified valve 2. This port communicates with an exhaust passage 8, exhaust pipe 6, intake passage 9 and an intake pipe 7. The exhaust passage 8 and the intake passage 9 respectively provide an exhaust control valve 4 and an intake control valve 5. The intake control valve 5 and the unified valve 2 are opened by closing the exhaust control valve 4 in an intake stroke, while the exhaust control valve 4 and the unified valve 2 are opened by closing the intake control valve 5 in an exhaust stroke. The unified valve 2, thermally deforming its seat part in an axis of symmetry, prevents a blow-by in the seat part.

    Abstract: Предлагаемый клапанный механизм газораспределения относится к области двигателестроения. Он содержит общий для впуска и выпуска клапан с подводящими каналами, внутри которых установлены заслонки, выполненные автоматически открывающимися под действием разности давлений, возникающей за счет смещения оси поворота заслонок относительно их осей симметрии. Заслонки установлены для разделения процессов впуска и выпуска. Они образуют три изолирующих полости: 1) впускной канал, 2) выпускной канал и 3) надклапанную полость. При такте впуска открываются одновременно общий клапан и заслонка впускного канала (заслонка выпускного канала при этом закрыта) и происходит впуск воздуха (или горючей смеси). При такте выпуска открывается этот же клапан и заслонка выпускного канала (заслонка впускного канала закрыта) и происходит выпуск отработанных газов. Закрываются заслонки возвратными пружинами, открываются – за счет разности давлений (при необходимости - электромагнитами) и фиксируются в закрытом состоянии по командам электронной системы управления двигателем. Для уменьшения неуравновешенных сил инерции при движении заслонок, возникающих в связи со смещением оси их поворота, на заслонках со стороны, в которую смещена ось поворота относительно оси симметрии, выполнены противовесы. Противовесы на заслонках обеспечивают уменьшение вибраций, износа и энергоемкости привода, за счет чего достигается высокая экономическая эффективность.

    Abstract: An extended circumference intake poppet valve system for use with a single charge carrying intake duct/port to an engine cylinder in a four cycle internal combustion engine to include three or more annular intake poppet valves (11) (secondary valves), annular valve seats (mini ports), disposed within a primary valve head (12) which spans said single duct/port (valve system), said valve system in fluid communication with said duct and said cylinder for opening and sealing said duct/port at said duct seat, intake valve lifting and closing means, wherein the area of the duct/port, and the matched area of the open valves are substantially equal for an extended optimum charge flow period, and in addition, valve open areas at all valve lift points during the inlet event that occur, initially and throughout extended duration through closure, are enlarged when compared with a single poppet valve servicing the same duct/port, resulting in greatly enhanced charge volume into the cylinder during the intake event.
