Abstract

The invention provides a pressure regulating valve for an oil supply line of an engine. The pressure regulating valve provided by the invention comprises a valve body, a valve plug and an iron core coil assembly, wherein the valve body is provided with a through channel; the valve plug is used for regulating the opening degree of the channel; the iron core coil assembly is used for operating the valve plug to regulate the opening degree of the channel; the magnetic force of the iron core coil assembly is controlled by the ignition switch of the engine; when the engine is ignited, the opening degree of the channel of the valve body is regulated to the minimum; and when the engine is started completely, the channel is completely started by the valve plug under the magnetic action of the iron core coil assembly. Compared with the existing pressure regulating device for the oil supply line of the engine, the pressure regulating valve provided by the invention is additionally arranged in the oil supply line of the engine, so that at the ignition stage of the engine, the opening degree of the oil supply line is regulated to the minimum by the pressure regulating valve, thus the pressure in the oil supply line increases instantly, high-pressure oil is provided for the ignition of the engine, and the engine can be ignited smoothly.

Description

technical field [0001] The invention belongs to the field of vehicle oil circuit pressure regulation, in particular to a pressure regulating valve capable of regulating the pressure of an engine oil supply circuit. Background technique [0002] The engine fuel supply system mainly includes a fuel pump, a fuel filter, and an oil pressure regulator connected by pipelines in sequence, wherein the fuel pump is placed in the fuel tank, and a channel of the oil pressure regulator is connected to the fuel tank through a pipeline; The pump, fuel filter, oil pressure regulator, and fuel tank form a circulating system. The pipeline between the fuel pump and the oil pressure regulator is connected to the pipeline connected to the engine. In the engine, the oil pressure regulator is mainly used to adjust the pressure of the oil pump line to the engine. [0003] At present, when the oil pressure regulator assembly is stopped and the oil pump stops working, the pressure of the pipeline s...
