    Abstract: An air flow in the combustion space which swirls or rotates about the cylinder longitudinal axis is produced for the fine distribution of the fuel by a correspondingly constructed inlet channel controlled by two inlet valves in a supercharged four-cycle internal combustion engine with direct fuel injection. With a low air mass flow, the rotary movement of the air in the combustion space is only weak and therefore prone to disturbance. An improvement is achieved by a change of the air flow in the inlet channel system. The valve actuation contains, for that purpose, an adjusting mechanism consisting of a piston-cylinder-unit fed with pressure oil, which effects in one operating function an automatic valve clearance compensation and which enables in a second operating function together with a controllable closure device in the pressure oil feed line a stoppage of one of the two inlet valves actuated in unison by the valve actuation. The reduction of the inlet cross section produces in the second operating function an increased inflow velocity of the air into the combustion space whereby at the same time the valve disk of the stopped inlet valve no longer projects interferingly into the circulating air stream.

    Abstract: A rocker arm comprises an actuator piston slidably disposed in an actuator piston bore formed in a motion imparting end thereof. A lash adjustment assembly is disposed in the motion imparting end and comprises an internal bore. A hydraulic passage is in fluid communication with the actuator piston bore and the internal bore. A resetting assembly is disposed in the lash adjustment assembly and comprises a reset slider and a checking element in fluid communication with the internal bore. The reset slider is slidably disposed in the internal bore and has a first end configured to engage a valve train component or engine valve, and has a second end with a resetting pin disposed thereon configured to contact and place the checking element in an unchecked state in response to positioning of the rocker arm when the first end contacts the valve train component or engine valve.

    Abstract: A lash compensator for a valve train component of an internal combustion engine is provided that includes an end-cap arranged within a reverse-spring control valve assembly of an axially moveable piston. The piston has a first reservoir and an inner radial wall configured with a through-aperture. The reverse-spring control valve assembly has a control valve housing, a bias spring, an end-cap, and a closing body. The end-cap is configured with a cupped end; an inner side of the cupped end receives a second lower end of the bias spring, and an outer side of the cupped end engages an upper portion of the closing body. The end-cap minimizes or eliminates the variation in flow resistance caused by a variation in end-coil geometry of the second lower end of the bias spring.

    Abstract: A valve lash adjuster for vehicles may include a piston having a body and an opening/closing unit. The body has an open surface in a bottom and an oil passage extending from a rocker arm shaft to the open surface, such that oil flows through the oil passage. The opening/closing unit is disposed on the oil passage to selectively open the oil passage depending on a pressure of the oil. A cylinder accommodates the piston. The cylinder slides downward to form an oil chamber between an inner side surface thereof and the piston. The oil chamber contains the oil therein.
