Abstract
The invention discloses a timing chain box of an internal circulation engine oil pump. The timing chain box of the internal circulation engine oil pump comprises a timing chain box body, a pressure relief valve and an engine oil pump, wherein the engine oil pump is installed at the bottom part of the timing chain box body, an engine oil pump cover is installed on the engine oil pump through a sunk screw, an outer rotor and an inner rotor are arranged in the engine oil pump, the pressure relief valve is installed on the timing chain box body, a pressure limiting valve spring is installed in the pressure relief valve, and the pressure relief valve is provided with an oil drain loop. Through the mode, the timing chain box of the internal circulation engine oil pump disclosed by the invention has the advantages that the structure is simple; since the oil drain loop is arranged beside the pressure relief valve and directly leads to the oil inlet chamber of the engine oil pump, the engine oil pump can continuously deliver oil inlet drained by the oil relief valve into the oil chamber during working.
Description
Technical field
The present invention relates to oil pump field, particularly relate 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.
Summary of the invention
The technical problem that the present invention 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 present invention 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, and described oil pump inside is provided with external rotor and internal rotor, and 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 a preferred embodiment of the present invention, 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 a preferred embodiment of the present invention, described Decompression valves is provided with pressure-limit valve plug screw.
In a preferred embodiment of the present invention, described oil pump is provided with oil suction chamber, and described leakage passage is connected with oil suction chamber.
The invention has the beneficial effects as follows: the timing chain cover of a kind of Inner eycle oil pump of the present invention, structure is simple, decreases environmental pollution, improves the working efficiency of oil pump, reduce energy consumption.
