Problems solved by technology
[0003] The structure and function of the electromagnetic control valves of the engine piston cooling nozzles currently on the market are relatively single, and they are mainly normally open valves, that is, the oil inlet and oil outlet of the electromagnetic control valve are kept in a normally open state, regardless of the pressure of the oil inlet, the oil outlet There will be lubricating oil flowing out of the port; in this way, when the pressure at the oil inlet is too low, the lubricating oil at the oil outlet can hardly achieve the cooling effect of the piston, resulting in a certain degree of waste

The invention discloses an electromagnetic control valve of an engine piston cooling nozzle with opening pressure. The electromagnetic control valve comprises an electromagnetic coil portion and a valve body connected with the electromagnetic coil portion. The electromagnetic coil portion comprises a shell, a coil arranged on an inner side of the shell, a yoke arranged on a peripheral side of thecoil and used for forming a magnetic circuit, and a plunger arranged on the inner side of the yoke. An inner cover is arranged on the inner side of the yoke. The valve body comprises a valve sleeve, and an oil inlet and an oil outlet are arranged in the side wall of the valve sleeve. An ejector pin, a valve element and a spring are successively arranged in the valve sleeve from top to bottom. Thevalve element comprises a first valve element body and a second valve element body which are independent. The first valve element and the second valve element can reciprocate in the valve sleeve alongan axial direction. The valve element is modified and designed into an independent two-section structure which includes the first valve element and the second valve element. Therefore, opening or closing of the oil outlet can be adjusted according to pressure of the oil inlet, a working state is adjusted too, and waste of lubricating oil can be avoided.
Description
technical field [0001] The invention relates to the technical field of engine electromagnetic control valves, in particular to an electromagnetic control valve with a cracking pressure engine piston cooling nozzle. Background technique [0002] With the development of the automobile industry and the application of technologies such as supercharging and high compression ratio, the combustion temperature of the engine is getting higher and higher, and the temperature of the environment where the piston is located is also getting higher and higher, which is prone to deflagration. Smoothness is very bad. Since the engine piston cooling system is widely used in automobiles, it is of great significance to reduce piston wear, prolong piston life, and ensure smooth engine operation. [0003] The structure and function of the electromagnetic control valves of the engine piston cooling nozzles currently on the market are relatively single, and they are mainly normally open valves, th...
