A type III rocker arm assembly operable in a first mode and a second mode based on rotation of a cam shaft includes a rocker shaft and a first rocker arm assembly. The first rocker arm assembly receives the rocker shaft and is configured to rotate around the rocker shaft in the first mode based on engagement with the first cam lobe. The first rocker arm assembly collectively comprises a valve side rocker arm, a cam side rocker arm and a latch pin. The valve side rocker arm defines a valve side rocker arm bore. The cam side rocker arm defines a cam side rocker arm bore. The latch pin assembly is received by the valve and cam side rocker arm bores and selectively couples the valve side rocker arm and the cam side rocker arm for concurrent movement in the first mode.

Rocker arm assembly having lash management for cylinder deactivation and engine brake configuration

A switching roller finger follower comprises an inner arm assembly. A pair of outer arms surround the inner arm assembly. A pivot axle connects the inner arm assembly to pivot with respect to the pair of outer arms from a starting position to a lost motion position. A latch assembly comprises a latch selectively movable from a latched position latching the inner arm assembly to move dependent with the outer arms and an unlatched position unlatching the inner arm assembly to pivot independent of the outer arms. A stop pin spans between the pair of outer arms and through an inner port in an axle of inner arm assembly. The stop pin comprises a clearance fit with the inner port, and the stop pin is configured pivotable independent of the outer arms. At least one return spring biases the stop pin toward the starting position.

Engine valve lifter having anti-rotation plug

A roller-lifter assembly for a cam-actuated engine, comprising a two-part roller lifter () comprising a pump actuator main body, a receiving portion extending from the main body (), and a cam follower comprising a roller assembly () or a flat tappet integrated to the main body and configured to follow a rotating cam of a cam-actuated () engine. A hydraulically-actuated capsule () is fitted to the receiving portion of the pump actuator, the capsule configured to rotate with respect to the pump actuator ().

Two-part lifter assembly

An engine roller lifter for use in a leak-valvetrain of an internal combustion engine includes a body, a roller and an anti-rotation plug. The body includes an outer peripheral surface configured for sliding movement in a bore provided in the engine. The bore is supplied oil by an oil passage communicating therewith. The body defines an opening. The roller bearing is rotatably mounted to the body and is configured for rolling contact with an engine camshaft. The anti-rotation plug is received at the opening and has a plug body including an anti-rotation protrusion that extends radially beyond an outer peripheral surface of the plug body. The anti-rotation plug can be staked into the opening of the body.

An engine roller lifter for use in a valve train of an internal combustion engine according to one example of the present disclosure includes a body and a groove formed in the body. The body has an outer peripheral surface configured for sliding movement in a bore provided in the engine. The bore is supplied by an oil passage communicating therewith. The body defines an axial pocket that receives a plunger therein. The groove is inset from the outer peripheral surface and formed about only a portion of a circumference of the body. The groove defines a first end and a second end. Only a portion of the first and second ends overlap with the oil passage to regulate the amount of oil supplied to the groove from the oil passage.
