摘要： A cooling system for a cylinder head of an internal combustion engine includes a cylindrical seat configured to engage an exhaust valve, a first coolant jacket, and a first conduit. The exhaust valve seat defines an annular cooling passage extending along a circumference of the cylindrical seat. A wall of the cylindrical seat defines a first opening into the annular cooling passage and a second opening into the annular cooling passage, where the first opening is positioned diametrically opposite to the second opening. The first coolant jacket is positioned adjacent to a fire-deck of the internal combustion engine. The first conduit fluidly couples the first coolant jacket to the at least one of the first opening and the second opening to the annular cooling passage in the exhaust valve seat.

摘要： An engine valve comprises an elongated hollow stem having a hollow head secured on an end thereof. A tube is disposed in the stem to define an inlet passage therethrough and an outlet passage between the tube and the stem. An annular oil distributor and heat conducting member, exhibiting a relatively high thermal conductivity, is secured to the tube and is disposed adjacent to an annular face defined on the head of the valve to conduct heat therefrom. The member defines a chamber along with an annular cap secured to the head of the valve. The chamber communicates with the inlet passage and the cap and the member function to direct oil radially outwardly to ports formed through the member to communicate oil to the outlet passage. The tube is preferably bent intermediate its ends to engage the stem in bearing contact to dampen vibration of the tube during operation.

摘要： An exhaust valve for an internal combustion engine that is cooled by circulation of cooling fluid such as water in internal conduits of the valve rod and valve head is described. The valve rod of this head is protected from chemical corrosion in the region thereof whose temperature in operation corresponds to the dew point. Thus, the exhaust gases can combine with water vapor to provide a corrosive chemical that corrosively attacks the usual metal of the valve rod in said region. To avoid this corrosion an externally located outer coating that is a metal alloy resistant to the chemical corroding action is applied to the surface of the valve rod in and about said region. In order to provide smooth unbroken continuity in external diameter of the valve rod in its adjoining alloy coated and uncoated portions the diameter of the valve rod in said region is reduced by an amount sufficient to accommodate the thickness of the applied alloy coating. This alloy may comprise carbon chromium, molybdenum, tungsten, iron, cobalt and nickel - or simply tungsten carbide with cobalt.

摘要： A head assembly for an internal combustion engine includes an electromagnetic valve actuation system. The head has an intake or exhaust passage defined therein. A valve is disposed in the passage and is operable to selectively open and close the passage. The head has a cooling passage defined therein for passage of a cooling fluid. An electromagnetic actuator has a piston in mechanical communication with the valve and a coil in fluid communication with the cooling passage. The electromagnetic actuator is operable to move the valve between a closed and an open position.
