Definitions

  • the invention relates to a valve gear for internal combustion engines, comprising two intake valves operated by means of rocker arms via a common valve. bridge arranged on the cylinder head in parallel relation to the valve stems, and a gas valve for each cylinder.
  • valve assembly is operated by means of three rocker arms located on the same axis, each rocker arm being controlled by one cam of the common camshaft, one of the said rocker arms cooperating with the valve bridge of the intake valves, the second with the valve bridge of the exhaust valves and the third with the gas valve preferably arranged in the longitudinal central plane of the internal combustion engine and eccentrically in relation to the cylinder axis.
  • the axis of rotation of the rocking levers forms an acute angle with the longitudinal central plane of the engine.
  • the forces are transmitted to the gas valve according to'another feature of the invention by the provision of a contact piece on the valve bridge in coaxial relation to the gas valve, cooperating with the extremity of the stem of the gas valve, preferably with the interposition of a spring element.
  • the valve clearance of the gas valve is adjusted independently from the separately adjustable valve clearance of the intake valves by means of the adjusting screw of the rocker arm.
  • FIG. 1 is a vertical cross-sectional view of the cylinder head of an internal combustion engine equipped with a gas valve according to the invention
  • FIG. 2 a horizontal cross-sectional view of the above on line 11-11 of FIG. 1, and
  • the two intake valves 2 are-arranged symmetrically in relation to the longitudinal central plane of the internal combustion engine. They are operated in the usual manner by means of the camshaft (not shown) via the rocker arm 4 and the valve bridge 3 comprising a centrally located hollow-cylindrical shaft 16 slidably arranged within an essentially cylindrical guide bushing 5 inserted in an appropriate bore of the cylinder head 1 with the interposition of gaskets 14.
  • the gas valve 7 is located with its valve guide 6 inserted in the central bore of the guide bushing 5 and resting on the same with a collar. The gas valve is sealed by means of a gasket 15 arranged in an annular groove in the central bore of the valve guide 6.
  • a va'lve gear for an internal combustion engine each cylinder of which comprises two intake valves arranged in suspension in the cylinder head in spaced and parallel relation to each other, a common inlet port for the two intake valves, a gas intake located in the cylinder head between the said intake valves, a bore provided between the intake valves in parallel relation thereto and extending from the top of the cylinder head through the said gas intake as far as the inlet port, a guide bushing inserted in the said bore and having apertures connecting the interior of the guide bushing with the said gas intake, a valve seat at the inner extremity of the said guide bushing, a valve guide coaxially arranged in the said guide bushing, a gas valve slidably guided in the said valve guide and cooperating with the said valve seat, a valve bridge having a hollow cylindrical shaft protruding into the said guide bushing and slidably guided therein, the said shaft surrounding the said valve guide of the gas valve, two thrust elements mounted on the valve bridge each in coaxial relation to the shaft of one of
  • valve gear according to claim 1 in which the said gas valve and the said guide bushing are arranged centrally in relation to the said two intake valves.
