Abstract: An engine valve train has oil flow to valve actuating components cut off or restricted when the valves are closed, to reduce parasitic losses. In an exemplary embodiment, a pushrod has a pivotable connection with a valve actuating rocker arm through which internal oil passages conduct oil for lubricating the rocker arm. The passages are aligned during valve actuation but become misaligned when the valve is closed. Misalignment of the passages at the sliding connection reduces the amount of oil flow through the connection to improve engine efficiency. When applied to cylinder deactivation engines, oil flow to rocker arms of deactivated valves is completely cut off, or reduced, further reducing parasitic losses.

Abstract translation: 发动机气门机构在阀关闭时切断或限制阀致动部件的油流，以减少寄生损耗。 在示例性实施例中，推杆具有与阀致动摇臂的可枢转连接，内部油通道通过该导向油导入油以润滑摇臂。 通道在阀门致动期间对准，但当阀门关闭时会变得不对齐。 在滑动连接处的通道的不对准减少了通过连接的油流量，以提高发动机效率。 当应用于气缸停用发动机时，流入停用阀的摇臂的油被完全切断或减少，进一步减少了寄生损失。

Abstract: A deactivation hydraulic valve lifter includes an elongate lifter body having a substantially cylindrical inner wall. The inner wall defines at least one annular pin chamber therein. The lifter body has a first end configured for engaging a cam of an engine. An elongate pin housing includes a substantially cylindrical pin housing wall and pin housing bottom. The pin housing wall includes an inner surface and an outer surface. The pin housing bottom defines a radially directed pin bore therethrough. The pin housing is concentrically disposed within the inner wall of the lifter body such that the outer surface of the pin housing wall is adjacent to at least a portion of the inner wall of the lifter body. A deactivation pin assembly is disposed within the pin bore and includes two pin members. The pin members are biased radially outward relative to each other. A portion of each pin member is disposed within the annular pin chamber to thereby couple the lifter body to the pin housing. The pin members are configured for moving toward each other when the pin chamber is pressurized, thereby retracting the pin members from within the annular pin chamber and decoupling the lifter body from the pin housing.
