A valve includes a valve body () disposable within a chamber () of a housing () and capable of being fluidly sealed with respect to the housing () when the valve is closed. At least one radial passage () is disposed in the valve body (). At least one axial passage () is disposed in the valve body () in fluid communication with the at least one radial passage (). When the valve at least partially opens, a fluid path opens between the valve body () and the housing (), which fluid path () in is fluid communication with the at least one radial passage (), and fluid from within the housing () is capable of passing out of the at least one axial passage ().

Valve having axial and radial passages

There is provided an apparatus for a reduced mass balancer shaft that effectively balance first or second order imbalances in an internal combustion engine. The balancer shaft is symmetrical with offset masses that are equal in magnitude and opposite in direction and orientation, and preferably comprises front and rear offset masses between a center section and a front and a rear journal respectively. In a preferred embodiment, there integrally formed stiffening members in the front and rear offset masses that symmetric about the balancer shaft centerline. The front and rear offset masses are each comprised of solid partial annular configurations that extend equally away from the balancer shaft centerline. The center section is comprised of an annular configuration.
