Embodiment Construction

[0014] Referring to the accompanying drawings, this unit pump electromagnet for automobile engine includes a housing 1, a coil (not shown in the figure), a coil bracket 6, an iron core 2 and a terminal post 3, and the coil is wound on an iron After the core 2 is installed, it is installed on the coil bracket 6 and placed in the housing 1. The wiring terminal of the coil is connected to the terminal 3, and the terminal 3 is provided with a device to prevent the fuel from flowing along the terminal. The device for preventing the fuel from flowing along the terminal post is to set a number of grooves 4 on the circumference of the terminal post 3, and the grooves 4 are not connected to each other; it is also possible to set a labyrinth on the circumference of the terminal post 3 No matter whether a number of grooves 4 or a labyrinth oil channel 5 are provided, it is all for prolonging the stroke of the fuel flow when the fuel leaks out. When making fuel oil leak, just achieved pur...

Abstract

The invention discloses a unit pump electromagnet for an automobile engine, which comprises a shell (1), a coil, a coil bracket (6), an iron core (2) and binding posts (3), wherein the coil is wound on the iron core (2) to be arranged on the coil bracket (6) and arranged in the shell, and binding terminals of the coil is connected with the binding posts (3). The unit pump electromagnet is characterized in that the binding posts (3) are provided with devices for preventing fuel oil from flowing along the binding posts. In the invention, devices for preventing fuel oil from leaking are arranged on the binding posts, thereby greatly improving the sealing performance of electromagnet packaging, so that when the unit pump electromagnet is used under the condition of high pressure at the temperature of 155 DEG C or -40 DEG C, no leakage occurs, and the continuous working life can reach more than 1500 hours.

Description

technical field [0001] The invention relates to an improved invention of an electromagnet, in particular to an improved invention for an electromagnet used in a unit pump of an automobile engine. Background technique [0002] my country's automobile industry has continued to develop at a high speed in recent years. According to the statistics of China Association of Automobile Manufacturers, the output in 2008 reached 9.35 million, including 1.64 million automobiles and trucks. With the increasing development of modern diesel engine technology, dieselization of automobile engines has become one of the measures for energy saving and emission reduction. The dieselization rate of automobile engines in my country is rapidly increasing, and the demand for diesel engines is increasing year by year. At present, foreign diesel engine fuel injection systems are using a large number of advanced electronically controlled unit pumps. The unit pump electromagnet is a key component to ...
