    Abstract: A valve bridge is disclosed for use with an internal combustion engine. The valve bridge may include a body with a central cavity formed in a center portion of the body for receiving a hydraulic lash adjuster, and opposing first and second lateral extensions on opposite sides of the central cavity. The valve bridge may further include a first bore in the first extension for receiving a first valve stem, and a second bore in the second extension for receiving a second valve stem. The valve bridge may also include a first internal groove in a wall of the central cavity configured to receive fluid, as well as a first internal passage in the body that extends from the first internal groove toward the first bore. In addition, the first internal passage may extend from a higher gravitational point within the body to a lower gravitational point within the body.

    Abstract: An internal combustion engine having a valve lifter assembly is disclosed. The internal combustion engine comprising an engine head having at least two wells adapted to receive at least one valve lifter, the at least one valve lifter includes a flat surface, at least one spacer installed within the engine head having a first surface, a hollow portion, and a second surface, the first surface is tapered with respect to a vertical axis of the at least one spacer, and a tie-bar plate for coupling the at least one spacer using head bolts. The at least one spacer and the at least one valve lifter are operatively arranged during operation in such a way that the flat surface of the at least one valve lifter faces the first surface of the at least one spacer to prevent rotation of the at least one valve lifter.

    Abstract: An anti-rotation guide for a lifter in an overhead valve valvetrain. The anti-rotation guide includes a plug having two lobes connected through a neck region. A first lobe of the plug is held within a bore in the lifter. The bore forms an opening at the edge of the lifter through which the neck of the plug emerges. The bore in the lifter accommodates a first lobe of the plug that is wider than the opening in the edge of the lifter, whereby the plug is shaped to prevent its slipping from the lifter through the opening. The lifter reciprocates in a first bore in the cylinder head. The second lobe of the plug extends outward from the lifter into a second bore formed in the cylinder head and adjoining the first bore. The second lobe reciprocates in the second bore and limits rotation of the lifter.

    Abstract translation: 一种用于顶置阀门阀门的升降机的防旋转导向器。 防旋转引导件包括具有通过颈部区域连接的两个凸角的插头。 插头的第一凸起保持在升降机的孔内。 孔在提升器的边缘处形成开口，通过该开口，塞子的颈部出现。 提升器中的孔容纳插头的第一凸起部，其比提升器的边缘中的开口更宽，由此插头成形为防止其从升降机通过开口滑动。 升降器在气缸盖中的第一孔中往复运动。 插头的第二凸耳从升降器向外延伸到形成在气缸盖中并邻接第一孔的第二孔。 第二个叶片在第二个孔内往复运动并限制了升降机的旋转。

    Abstract: A compression-release brake system is provided that includes a lost motion exhaust rocker assembly, an actuation piston, and a reset device. The actuation piston includes an actuation piston body that is slidably received by the rocker arm to define a piston cavity in the rocker arm and is movable between piston retracted and extended positions. The actuation piston is configured to be operatively associated with the exhaust valve to permit unseating of the exhaust valve from the seated state. An actuation piston check valve is configured to move between closed and open positions to permit hydraulic fluid flow through an actuation piston communication port to the piston cavity. The reset device includes a reset check valve and a reset pressure control spring for applying a biasing force to the reset check valve to urge the reset check valve toward an open position.

    Abstract: A valve actuation system is disclosed for an internal combustion engine. The system may have a gas exchange valve, a rocker arm pivotally connected to a shaft, a pushrod, a lash adjuster disposed in the pushrod. The system may also have an adjusting screw disposed in the rocker arm and configured to engage and fluidly supply the lash adjuster. The adjusting screw may include a shaft having a threaded outer annular surface, and a head connected to the shaft and having a rounded outer surface and a flat end face. The adjusting screw may also include an axial passage passing through the flat end face, a radial passage formed in the shaft and extending from the threaded bore of the rocker arm to the axial passage, and at least one radial groove formed in the rounded outer surface of the head and passing through the axial passage.
