摘要： An oil distribution system for an internal combustion engine comprising a longitudinal bore in the engine head or block connected to an engine oil pump. A longitudinal insert is disposed in the engine bore, the insert being formed and disposed to define segmented galleries within the bore, a first oil gallery being in communication with the engine camshaft bearings and a second oil gallery being in communication with switchable cam followers in the engine. The two galleries are separated but connected by one or more oil control valves. Thus, the camshaft bearings are exposed to high engine oil pressure at all times independent of the switchable cam followers; likewise, the switchable cam followers may be latched and unlatched at any time or condition deemed beneficial for engine operation without jeopardizing lubrication sufficiency to the camshaft bearings.
摘要翻译： 一种用于内燃机的油分配系统，包括在与发动机油泵连接的发动机机头或块中的纵向孔。 纵向插入件设置在发动机孔中，插入件被形成并设置成在孔内限定分段的画廊，第一油画廊与发动机凸轮轴轴承连通，第二油画廊与可切换的凸轮从动件连通 发动机。 两个画廊分开，但由一个或多个油控阀连接。 因此，独立于可切换的凸轮从动件，凸轮轴轴承始终暴露于高发动机机油压力。 同样地，可切换的凸轮从动件可以在任何时间或条件下被锁定和解锁，被认为对发动机运转有利，而不会危及凸轮轴轴承的润滑性。
