Technical Field
The utility model relates to an integrated feedback oil duct of machine oil pump case and piston cooling nozzle shutoff functional structure among the automobile gasoline engine technical field.

Currently, lubricating oil is required to lubricate the surfaces of moving parts during engine operation in order to reduce frictional resistance and wear, and to reduce power consumption of the engine. In order to obtain a sufficient pressure and flow of lubricating oil, the oil pump is required to continuously deliver a sufficient amount of clean oil at a proper temperature to the friction surfaces of all transmission members, so as to form an oil film with a lubricating effect. The friction of parts can be effectively relieved, the power loss can be reduced, the service life of the engine is ensured, and a good working state is provided.
Firstly, lubricating oil is sucked from an oil sump by an oil pump, then the lubricating oil is pumped into an oil cooler, the cooled lubricating oil enters a main oil duct at the lower part of a cylinder body after being filtered by an oil filter, and is conveyed to each lubricating point from bottom to top under the action of pressure.
In order to reduce oil consumption and discharge pollutants, the engine adopts a variable oil pump, so that a main oil duct at the lower part of an engine cylinder body is required to be communicated with a feedback oil cavity in the oil pump, and the on-off of a feedback oil path is realized through a switch of an electromagnetic valve, so that the oil pressure is regulated; meanwhile, the engine cylinder body also comprises a cooling nozzle oil way, and engine oil is sprayed to a specified position through a piston cooling nozzle under the action of oil pressure, so that the piston is cooled.
In order to realize the functions, two oil passages are required to be processed on the cylinder body, one oil passage is used for communicating the main oil passage with the oil pump, and the other oil passage is used for cooling the nozzle of the piston. In the process of machining a cylinder body of a traditional engine, a main oil duct needs to be machined, a feedback oil duct needs to be machined, and the main oil duct is communicated with the feedback oil duct. After the piston cooling nozzle oil passage is processed, the end part needs to be plugged by a plugging cover, or the end part needs to be sealed by a sealing ring and a cover separately, and the sealing ring and the cover are screwed down by a flange bolt, so that the engine oil is prevented from flowing out, and the oil pressure reaching each piston cooling nozzle is ensured to be enough. Such arrangement increases the part machining process, complicates the structure, increases the part cost, and increases the risk of engine oil leakage to a certain extent. Therefore, the development of a functional structure integrating a feedback oil passage and a piston cooling nozzle plugging of a pump shell of the engine oil is a new problem to be solved urgently.
