Abstract
An oil supply carrier assembly configured to be mounted to a valve train carrier having a plurality of rocker arms according to the present disclosure includes an oil supply carrier housing having a first oil inlet port and a second oil inlet port. The oil supply carrier housing supports an oil control valve and further includes first, second and third oil supply passages. The first oil supply passage is configured to deliver oil from the first oil inlet port on the valve train carrier to the oil control valve. The second oil supply passage is configured to deliver oil from the valve train carrier to at least one engine brake rocker arm of the rocker arms. The third oil supply passage is configured therein to deliver oil from the second oil inlet port to the rocker arms.
Claims19
An oil supply carrier assembly configured to be mounted to a valve train carrier having a plurality of rocker arms, the oil supply carrier assembly comprising:
- an oil supply carrier housing having a first oil inlet port and a second oil inlet port, the oil supply carrier housing supporting an oil control valve and further having:
- a first oil supply passage configured therein to deliver oil from the first oil inlet port on the valve train carrier to the oil control valve, wherein the first oil supply passage is collectively defined by a first oil bore and a second oil bore formed along intersecting non-linear axes, the first oil bore fluidly connected to the first oil inlet port, the second oil bore fluidly connected to the oil control valve;
- a second oil supply passage configured therein to deliver oil from the valve train carrier to at least one engine brake rocker arm of the rocker arms;
- and
- a third oil supply passage configured therein to deliver oil from the second oil inlet port to the rocker arms.
