Embodiment Construction
[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. 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.
[0023] Such as Figure 1-6 As shown, a fuel injector with a variable-diameter umbrella-shaped nozzle includes a needle, and a fixed groove 4 is formed at the top of the needle 1, and a movable rod 2 is snapped into the fixed groove 4, and the movable rod 2 The other end clamps the movable piece 3, and the movable piece 3 surrounds the outside of the needle 1. The movable piece 3 is divided into a backing plate 9 and a deflector. The midline of the backing plate ...

The invention discloses a variable-diameter umbrella-shaped nozzle oil sprayer which comprises a shaft needle. A circle of fixing groove is formed in the top end of the shaft needle, a movable rod is clamped in the fixing groove, the other end of the movable rod is clamped with a movable piece and surrounds the shaft needle through the movable piece, the movable piece is divided into an abutting plate and a flow guide plate, and a drainage groove is formed in the center line of the abutting plate. In the starting state, the drainage groove in the abutting plate abuts against oil spraying holes, the flow guide plate is located in an oil spraying groove, and in the stopping state, the flow guide plate abuts against the oil spraying holes. The movable piece is connected to the top end of the shaft needle, the movable piece surrounds the shaft needle to form a conical barrel with the changeable diameter, and the oil spraying holes spray oil along the movable piece, so that the atomization effect is better, and carbon deposition is not likely to happen.
Description
technical field [0001] The invention relates to the field of fuel injectors, in particular to a variable-diameter umbrella-shaped nozzle 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. The fuel injector receives the fuel injection pulse signal sent by the ECU to precisely control the fuel injection quantity. [0003] Because there are hydrocarbons, paraffins, and colloids in the fuel that cannot be completely burned, they will be burned into colloidal carbon, which will block the fuel injection hole over time, making the fuel atomization state poor. Contents of the invention [0004] According to the technical problem to be solved by the present invention, the present invention provides a variable-diameter umbrella-shaped nozzle fuel injector. [0005] In order to achieve...
