Detailed description of the invention
Fig. 1 is structural schematic diagram proposed by the present invention；
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.
In the description of the present invention, it is to be understood that, term " on ", "lower", "front", "rear", "left", "right", "top",
The orientation or positional relationship of the instructions such as "bottom", "inner", "outside" is to be based on the orientation or positional relationship shown in the drawings, merely to just
In description the present invention and simplify description, rather than the device or element of indication or suggestion meaning must have a particular orientation, with
Specific orientation construction and operation, therefore be not considered as limiting the invention.
Referring to Fig.1, camshaft phaser, including outer cover 1, front cover 2, rotor 3, stator 4 and the rear cover 5 set gradually,
It is characterized in that: being equipped with machine oil between front cover 2 and stator 4 and recycle plate 6, the torque recycling of rotor 3, which generates, to be rotated and then utilize
Machine oil recycles plate 6 and carries out machine oil recycling.
Front cover has oilhole 7 close to stator rim position in each chamber, and the recycling for machine oil between two chambers uses.
After loading onto machine oil recycling plate, check valve sheet is just overlapped with the oilhole of front cover everywhere.
One, when VVT active accommodation, if control valve driving rotor drives camshaft forward rotation, at this time rotor side
Chamber fuel feeding, another side chamber oil extraction, while rotor oil-discharging cavity check valve sheet is acted on by oil pressure, is bonded with front cover, and sealing is formed；It is on the contrary
?.
Two and engine when operating normally, camshaft itself is acted on by the alternation of various load torques, therefore is had small
The twisting vibration of range, rotor drives rotation by camshaft in turn at this time (i.e. the torque of rotor recycles).Positive rotation such as occurs
Turn, oil-discharging cavity is pressurized at this time, and check valve sheet still seals, and fuel feeding lumen type chamber increases, and forms negative pressure, will be deposited by check valve sheet
The oil sucking supplement (i.e. machine oil recycling) being stored between outer cover and front cover；Vice versa.
Three, income:
1. the oil-filled rate of driver is accelerated, to make regulating the speed for VVT under the collective effect of one and two principles
It is improved (according to relevant information, the 150 °C of A that can regulate the speed from general driver are promoted to 300 °C of A+)；
2. the machine oil reduction for flowing into working chamber is directly supplemented from central control valve simultaneously because the recycling of machine oil acts on, from
And reduce VVT system to the consumption of machine oil, it improves (main to the dependence of oil pump and a whole set of engine lubrication pipe-line system
If the influence of flow).
The front cover 2 is equipped with several oilholes 7, several oilholes 7 are located at what rotor was cooperatively formed with stator
8 position of cavity margin, machine oil recycle plate 6 and are equipped with several check valve sheets 9, and check valve sheet 9 is covered on oilhole 7.
The front cover 2, machine oil recycling plate 6 are fixedly connected by bolt with stator 4.
Two marginal positions of one of chamber that rotor 3 and stator 4 cooperatively form are respectively provided with the oilhole 7 of front cover, machine
Check valve sheet 9 on oil recycling plate 6 is covered on oilhole 7.
The rotation of the rotor, the chamber of rotor side generate negative pressure and open check valve sheet sucking in front cover oilhole
Oil；The chamber of the rotor other side then generates positive pressure closed check valve piece.
The check valve sheet is: the slot 10 of U-typed is machined on machine oil recycling plate, the inside of slot forms check valve sheet,
The end 11 of check valve sheet is rounded and can cover the oilhole on front cover.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
