Description

Fuel metering valve with adjustable locking nut performance Technical Field The utility model relates to a fuel technical field specifically is a take adjustable fuel metering valve of locking nut performance. Background A valve installed at the oil inlet position of a high-pressure oil pump is used for adjusting the fuel supply quantity and the fuel pressure value when the fuel metering valve is used. And its regulation requirements are controlled by the ECU. The ECU increases or decreases the oil quantity by changing the oil inlet sectional area of the high-pressure oil pump through the pulse signal. When the control coil is electrified, the fuel metering valve is conducted, and the fuel metering proportional valve can provide the maximum flow rate of fuel. The original riveting structure product of the existing fuel metering valve possibly causes performance deviation, the back choke is slightly deformed in the riveting process due to the fact that the adjusting screw plug (copper material) is slightly deformed, the deformation of the back choke directly influences the loss of fuel quantity, once the fuel quantity is lost, the product cannot be repaired, the product is scrapped, and aiming at the situation, the fuel metering valve with the adjustable locking nut performance is provided.
