Embodiment Construction
[0014] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0015] see figure 1 , the embodiment of the present invention includes:
[0016] A new type of fuel injector, comprising: an oil inlet 1, an oil inlet pipeline 2, a pressure regulating device and an oil injection nozzle assembly 3.
[0017] The oil inlet 1 communicates with a high-pressure chamber 9 through the oil inlet pipe 2, and the pressure regulating device includes a pressure regulating spring 4, a pressure regulating plate 5 and a push rod 6, and one end of the push rod 6 is connected to the pressure regulat...

The invention discloses a novel oil sprayer. The novel oil sprayer comprises an oil inlet, an oil inlet pipeline, a pressure adjusting device and an oil spraying nozzle coupling part, wherein the oil inlet is communicated with a high-pressure cavity by the oil inlet pipeline; the pressure adjusting device comprises a pressure adjusting spring, a pressure adjusting plate and anejectorrod; one end of ejector top rod is connected with the pressure adjusting spring, and the other end of theejector rod is connected with the high-pressure cavity; the pressure adjusting plate is arranged at the other end of the pressure adjusting spring; and the high-pressure cavity is arranged in the oil spraying nozzle coupling part. The novel oil sprayer disclosed by the invention has the advantages that by the mode, the distance of an oil spraying pipe can be shortened; and since the high-pressure cavity is arranged in the oil spraying nozzle coupling part, the length of the oil spraying nozzle is increased, the performance of the oil sprayer is improved and the pressure-adjusting structure is also simple, convenient and accurate.
Description
technical field [0001] The invention relates to the field of fuel injectors, in particular to a novel fuel injector. Background technique [0002] The fuel injector is a precision device with very high machining accuracy, which requires a large dynamic flow range, strong anti-clogging and anti-pollution capabilities, and good atomization performance. [0003] The structure of the fuel injector in the prior art is various, but most of the structures limit the size of the fuel injector, the oil inlet pipe is too long, the structure is complicated, and the pressure regulation is complicated, which affects the performance of the fuel injector. The best fuel injection effect cannot be achieved. Contents of the invention [0004] The technical problem mainly solved by the present invention is to provide a new type of fuel injector, which can shorten the length of the oil inlet pipe and lengthen the fuel injector, which is helpful to control the overall performance of the fuel i...
