Engine oil nozzle device capable of absorbing oil, adjusting quantity and stabilizing pressure

Abstract

The invention discloses an engine oil nozzle device capable of absorbing oil, adjusting quantity and stabilizing pressure, which comprises a gear and rack meshing transmission device of an upper cavity, a gear is connected with a motor, the middle of a rack is V-shaped and is used for connecting and disconnecting an oil way, the lower part of the rack can compress oil to pressurize, the right side of a middle cavity is an oil inlet, and a spring in a lower cavity is connected with a valve block. And the bottom end of the valve block is provided with an oil injection cavity and an oil injection port. According to the device, opening of an oil way on one side of the middle is controlled through gear and rack meshing transmission, the cavity size is increased, pressure difference is generated through pressure reduction, oil is sucked, and the oil quantity of an oil injection cavity can be controlled by controlling the opening time of the oil way, so that the oil injection quantity is controlled. The gear rotates clockwise, the left oil way is opened, the right oil way is closed, and oil enters the oil injection cavity; when the gear rotates anticlockwise, the left oil way is closed, the right oil way is opened, the oil extrudes the valve block downwards, the valve block extrudes the oil in the oil spraying cavity, the oil is sprayed out, and the oil on the upper portion of the valve block flows back to the oil tank from the oil outlet.

Description

technical field [0001] The invention belongs to the technical field of engine fuel injection nozzles, and in particular relates to the design of an engine fuel injection nozzle device capable of absorbing oil, adjusting volume and stabilizing pressure. [0002] technical background [0003] The fuel supply system of a traditional engine is mainly composed of a fuel storage tank, a hydraulic pump and an injector. The fuel is delivered to the injector by the hydraulic pump and is ignited and burned after entering the combustion chamber of the engine. With the advancement of technology and the integration of industrialization, more and more attention has been paid to the efficiency and economy of engines. More and more researchers are trying to improve the efficiency and economy of engine injectors by designing lighter devices. And the current engine fuel injectors are more concerned with improving the atomization degree of the sprayed oil to increase the combustion efficiency, ...

AI Technical Summary

Problems solved by technology

And the current engine fuel injectors are more concerned with improving the atomization degree of the sprayed oil to increase the combustion efficiency, but for the defects of the fuel injector itself, such as the change of the fuel distribution with the fuel supply pressure, the outlet temperature distribution is not suitable for control , easy oil accumulation, complex structure and high cost are relatively less studied
