tilt mechanisms for a swing arm and lost motion component of a valve bridge

摘要

The present invention relates to systems for actuating at least two engines comprising a valve bridge operably connected to at least two engine valves and having a hydraulically actuated lost motion component. an oscillating arm has a motion receiving end configured to receive valve actuation movements from a valve actuation motion source and a motion transmission end to transmit valve actuation movements and hydraulic fluid to the component. of lost movement. the motion receiving end is angled toward the valve actuation motion source. a tilt mechanism, supported by either the swingarm or valve bridge, or both, is configured to tilt the motion receiving end of the swingarm and the motion component lost in contact with each other. By maintaining such contact, the tilt mechanism helps maintain the supply of hydraulic fluid from the swingarm to the lost motion component.
