The invention provides an oil inlet transverse cavity clamp for an oil sprayer. The oil inlet transverse cavity clamp comprises an oil sprayer mounting seat, a transverse cavity mounting block, two fastening bolts and a universal oil inlet transverse cavity; an oil sprayer mounting hole, two guide holes, two groove holes and a through groove are formed in the oil sprayer mounting seat in the vertical direction; the guide holes are formed in the front ends of the two sides of the oil sprayer mounting hole at intervals, and openings are formed in the front ends of the guide holes; and the position of the universal oil inlet transverse cavity can be adjusted along the guide holes through the transverse cavity mounting block and the fastening bolts, and the universal oil inlet transverse cavity is rotationally connected to the oil sprayer mounting seat. According to the oil inlet transverse cavity clamp for the oil sprayer, the mounting position and the mounting angle of the oil inlet transverse cavity can be flexibly adjusted according to the height and the angle of an oil inlet hole of the oil sprayer, the oil inlet transverse cavity clamp is suitable for various oil sprayers of different specifications and sizes, the economic cost and the time cost invested for designing and machining special oil inlet transverse cavity clamps for the oil sprayers of different specifications and sizes are reduced, and the performance testing and verifying efficiency of the oil sprayer is improved.
Description
technical field [0001] The invention relates to the technical field of fuel injection systems for diesel engines, in particular to a fixture for an oil inlet transverse chamber of an injector. Background technique [0002] The fuel injector is a key part of the fuel injection system of a diesel engine, and its injection performance is crucial to the power, economy and emission performance of a diesel engine. In order to obtain the working characteristics of the fuel injector and ensure the quality of the fuel injector products during the design, research and manufacturing process of the fuel injector, it is necessary to test and verify the various injection characteristics of the fuel injector. Modern diesel engines usually use horizontal cavity fuel injectors to improve the compactness of the structure. The horizontal cavity fuel injectors need to use the pressure connection between the horizontal cavity and the injector oil inlet hole to achieve contact sealing and will be...
