Embodiment

[0024] Such as figure 1 , figure 2 As shown, an axial compression distribution pump with adjustable oil supply pressure and oil volume mainly includes an oil pump device, an oil pressure adjustment device and an oil volume adjustment device. The oil pumping device is mainly composed of a pump body 14, a plunger sleeve 13, a distribution plunger 12 and a solenoid valve B17. The oil pressure regulating device is mainly composed of spring seat A2, spring A3, slider A5 and electromagnetic coil A4. The spring seat A2 is installed on the electromagnetic coil A4, and the two ends of the spring A3 are respectively connected to the spring seat A2 and the slider A5. The quantity of the spring A3 The slider A5 is designed to have a circular cross-section and a "shi" structure; the electromagnetic coil A4 generates magnetic force after being energized, overcomes the elastic force of the spring A3 and attracts the slider A5 to move axially, and the electromagnetic coil A generates The s...

Abstract

The invention provides an axial compression type dispensing pump with adjustable oil supply pressure and oil mass. The axial compression type dispensing pump mainly comprises a pump oil device, an oil pressure adjusting device and an oil mass adjusting device. The axial compression type dispensing pump is characterized in that dual functions of adjusting oil supply pressure and oil mass are achieved by the power driving of a single solenoid valve A. According to the invention, oil supply opening and closing, temporary storage of oil residues and weight reduction can be realized by a sliding block A with section in 'Shi'-shaped structure ( 'Shi' is a Chinese character); and oil supply adjustment can be realized by the coordination of a protruding board and an oil mass adjusting push plate.

Description

technical field [0001] The invention relates to an axial compression distribution pump with adjustable oil supply pressure and oil volume, in particular to a single solenoid valve A driven by power to realize dual functions of adjusting oil supply pressure and oil volume; The sliding block A with "shi"-shaped structure realizes opening and closing oil supply, temporary storage of oil residue and weight reduction; through the cooperation of the convex plate and the oil volume adjustment push plate, the adjustment of the oil supply volume is realized, which belongs to the technology of the axial compression distribution pump R & D field. Background technique [0002] The axial compression distribution pump uses a group of fuel supply elements to supply fuel to each cylinder of the diesel engine in a fixed and quantitative manner through the distribution mechanism. However, due to the unitary structure of the current axial compression distribution pump, the following problems ...
