Abstract

The invention relates to the field of internal combustion engines, and particularly discloses a fuel oil regulating pump provided with a spring vibrating device. The fuel oil regulating pump provided with the spring vibrating device comprises a fuel oil regulating pump body, a throttling part, an oil pumping pipe and an oil return pipe. The fuel oil regulating pump body is fixedly connected with an oil filling port of the throttling part through the oil pumping pipe. One end of the oil return pipe is fixedly connected with the throttling part, and the other end of the oil return pipe is fixedly connected with the fuel oil regulating pump body. The throttling part is divided into a low pressure area, a suction area and a regulating valve sliding in the low pressure valve and the suction area. A clamping ring is arranged in the middle of the regulating valve, and the clamping ring and the regulating valve are integrally formed. The clamping ring is located in the low pressure area. A buffering device connected with the lower end of the regulating valve is arranged in the low pressure valve and located below the clamping ring. The spring vibrating device is arranged in the low pressure area. The upper end of the spring vibrating device is fixedly connected with the lower surface of the clamping ring of the regulating valve. The lower end of the spring vibrating device is a free end. According to the scheme, by arranging the vibrating device, an oil storage chamber and an oil inlet pipe are prevented from being blocked.

Description

technical field [0001] The invention belongs to the field of internal combustion engines, in particular to a fuel regulating pump with a spring vibrating device. Background technique [0002] The function of the fuel pump is to suck the fuel out of the fuel tank, pressurize it and deliver it to the fuel supply pipe, and cooperate with the fuel pressure regulator to establish a certain fuel pressure. It is one of the basic components of the fuel injection system of an EFI vehicle. In order to allow fuel to mix with air quickly, it is necessary to inject a sufficient amount of fuel in a very short time. At this time, the fuel pressure adjustment pump is required to increase the fuel injection pressure, so that a sufficient amount of fuel can be injected and mixed with air for rapid combustion. [0003] Patent No. CN103270289A invention patent discloses a pressure regulating device with a fuel injection system for internal combustion engines operated by a pump, with a valve arr...
