Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As Figure 4-Figure 6, the present embodiment provides a kind of VVT phaser oil channel structure, including
VVT phaser rotor 5 after improvement, which is provided with VVT phaser rotor oil duct 51,
VVT phaser rotor oil duct 51 includes end face hydraulic fluid port 513, and is communicated with VVT phaser oil pocket 6
The first hydraulic fluid port 511 and the second hydraulic fluid port 512, the quantity of VVT phaser rotor oil duct 51 is two, and bolt 2 is removed
Original axial oil duct 21 and radial direction oil 22, preferred bolt 2 can select common standard bolt.Fluid is through oil cylinder head way
By external hydraulic fluid port 4, into camshaft oil gallery, the camshaft oil gallery preferably is positioned at the second cam shafting oil of the both sides of bolt 2
Road 3b, and by the end face hydraulic fluid port 513 in VVT phaser rotor 5, flow into rotor oil duct 51, further by the
One hydraulic fluid port 511 and the second hydraulic fluid port 512 enter VVT phaser oil pocket 6.In said structure, VVT phase
Device rotor is changed to end face oil-feed from original radial direction oil-feed, and end face hydraulic fluid port 513 is directly connected with the second camshaft oil gallery 3b, middle
