Abstract
The utility model provides an oil inlet pipe of a high-pressure oil injector, and belongs to the technical field of high-pressure oil injectors. The oil inlet pipe solves the problems that according to an existing structure, filtering screens are not easily installed, and installation is not firm enough. The oil inlet pipe of the high-pressure oil injector comprises an oil inlet pipe body. The oil inlet pipe body comprises an upper casing pipe and a lower casing pipe in screw connection with the upper casing pipe. An oil filtering screen is arranged at the position where the upper casing pipe is combined with the lower casing pipe. An annular groove is formed in the inner wall of the upper end of the upper casing pipe. A check valve is arranged inside the annular groove. The oil inlet pipe of the high-pressure oil injector has the advantages that the filtering screen is fixed in position, is easier and more convenient to install and the like.
Description
Technical field
