[0030] 下面根据附图对本发明进行详细描述,其为本发明多种实施方式中的一种优选实施例。 [0030] The following detailed description of the present invention based on the drawings, of a number of embodiments which preferred embodiments of the present invention.

[0031 ] 如图1、图2所示,一种同时具有VVT和VVL技术的可变气门机构的驱动油路,机油经由缸体主油道1流至缸盖主油道2处,继而分别流入进气凸轮轴轴颈供油油道5、VVT油路入口4、排气凸轮轴轴颈供油油道7。 Drive oil passage [0031] As shown in FIG 1, FIG. 2, having both a variable valve mechanism and VVT VVL art, the main oil gallery of the cylinder via the oil stream at a main oil gallery to the cylinder head 2, respectively, then flowing into the intake camshaft journal oil supply passages 5, VVT inlet passage 4, an exhaust camshaft journal oil supply passage 7. 进气凸轮轴轴颈供油油道5里的机油,进一步流入排气液压间隙调节器油路12以VVL系统控制油路入口13。 Oil intake camshaft journaled in the oil supply channel 5, the exhaust gas further flows into the hydraulic lash adjuster oil passage 12 to the inlet passage 13 VVL control system. VVT油路入口4布置在缸盖中间,VVT油路中安装有单向阀6,其安装位置位于VVT油路入口4和VVT系统OCVl 1之间,且单向阀6的数量与相位器数量相同。 VVT inlet passage 4 is arranged in the middle of the cylinder head, oil VVT-way valve 6 is installed, its installation position is located between an inlet passage 4 VVT and VVT system OCVl, and the phase number of the check valve 6 the same.

[0032] 所述的VVL系统控制油路入口13处的机油,经VVL系统0CV14控制其是流入进气液压间隙调节器油路15还是流入VVL系统泄油孔16。 VVL system [0032] control the passage of oil at the inlet 13, the VVL control system 0CV14 which is flowing into the intake passage of the hydraulic lash adjuster 15 or the vent hole 16 flows into the VVL systems. VVL系统0CV14保证进气液压间隙调节器油路15能够在VVL系统泄油时达到液压间隙调节器正常工作所需的油压,又不会达到VVL系统切换所需的油压。 VVL systems 0CV14 ensure an intake passage of the hydraulic lash adjuster 15 to achieve normal operation of the hydraulic lash adjuster when the hydraulic pressure required VVL drainage system, but the system does not reach the VVL required for switching the hydraulic pressure. 当VVL系统0CV14控制VVL系统控制油路入口13处的机油流入进气液压间隙调节器油路15时,进气液压间隙调节器油路15中的高压油将驱使两级液压间隙调节器或两级指形滚子摇臂中的切换装置运动,从而实现从低升程到高升程的切换;当VVL系统0CV14控制VVL系统控制油路入口13处的机油流入VVL系统泄油孔16 时,进气液压间隙调节器油路15中的油压仅能维持液压间隙调节器正常工作,两级液压间隙调节器或两级指形滚子摇臂中的切换装置将回到初始位置,实现从高升程到低升程的切换。 When the system 0CV14 VVL VVL control system controls the inlet of oil at the oil passage 13 into the intake hydraulic lash adjusting the oil passage 15, the intake hydraulic lash adjuster high pressure oil passage 15 will drive two hydraulic lash adjuster or two stage switching roller finger means of the sub-rocker arm motion, thereby switching from a low lift to high lift; when the VVL control system 0CV14 VVL control system the inlet passage 13 into the oil at the VVL systems vent hole 16, into the gas hydraulic lash adjuster oil passage 15 of the hydraulic lash adjuster is maintained only work, two hydraulic lash adjuster or two fingers in the roller rocker switching means to the initial position, achieved from the high to drive the low lift switch.

[0033] 本实施例只针对VVL系统的控制油路,不涉及两级液压间隙调节器或两级指形滚子摇臂的内部具体结构,也不涉及VVL系统0CV14内部具体结构。 [0033] The specific configuration of the present embodiment only 0CV14 internal passage for VVL control system embodiment does not involve two internal hydraulic lash adjuster or a specific configuration of the two roller rocker fingers, it does not involve VVL systems.

[0034] 所述的VVT油路入口4处的机油,经由单向阀6流入VVT系统OCVll的环形入油孔,通过由进油孔或回油孔8和回油孔或进油孔9组成的回路,驱动相位器工作,最终流入泄油孔10,回到油底壳中。 [0034] VVT said oil passage inlet 4, the check valve 6 into the annular OCVll VVT system via hole into, or back into the hole by the hole or the hole 8 and back into the hole 9 Composition the circuit operates drive phase, eventually into the vent hole 10, back to the sump.
