Description
Technical field
The utility model relates to oil pump field, particularly relates to a kind of timing chain cover of Inner eycle oil pump.
Background technique
Oil pump effect, after machine oil being brought up to certain pressure by gears meshing rotation, is sent to the moving parts surface that motor respectively need lubricate forcibly.Its structure many employings gear type oil pump.During engine operation, bent axle drives driving gear transmission, and driven gear accompanies rotation.Due to volume from large to small, the machine oil in oil sucting cavity just enters out oil pocket along backlash and pump wall pressure, and the machine oil of certain pressure is pumped into lubricating oil path.
Conventional machine oil pump has the phenomenon of draining, and the oil released easily is wasted, and adds environmental pollution, reduces the working efficiency of oil pump.
Model utility content
The technical problem that the utility model mainly solves is to provide a kind of timing chain cover of Inner eycle oil pump, structure is simple, at the other employing of Decompression valves one leakage passage, this loop directly passes into oil pump oil suction chamber, oil pump is made operationally continuously the oil that Decompression valves gushes to be delivered into oil pocket, thus decrease environmental pollution, improve the working efficiency of oil pump, reduce energy consumption.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: the timing chain cover providing a kind of Inner eycle oil pump, comprise timing chain box body, Decompression valves and oil pump, the bottom of described timing chain box body is provided with oil pump, described oil pump is provided with oil pump cover by sunk screw, described oil pump inside is provided with external rotor and internal rotor, described timing chain box body is provided with Decompression valves, described Decompression valves is provided with limiting valve spring, and described Decompression valves is provided with leakage passage.
In the utility model preferred embodiment, gap between described internal rotor and external rotor is 0.06-0.20cm, gap between the side of described internal rotor, external rotor and timing chain box body is 0.04-0.095cm, gap between described external rotor and timing chain box body is 0.10-0.181cm, and the gap between described internal rotor and timing chain box body is 0.03-0.085cm.
In the utility model preferred embodiment, described Decompression valves is provided with pressure-limit valve plug screw.
In the utility model preferred embodiment, described oil pump is provided with oil suction chamber, and described leakage passage is connected with oil suction chamber.
The beneficial effects of the utility model are: the timing chain cover of a kind of Inner eycle oil pump of the utility model, and structure is simple, decreases environmental pollution, improves the working efficiency of oil pump, reduce energy consumption.
