Below in conjunction with the drawings and specific embodiments detailed structure of the present invention is further described.
Description of drawings
Accompanying drawing 1 is a structural representation of the present invention;
Accompanying drawing 2 is regulated integrated valve modular construction schematic representation safely for being installed in the disjunctor valve opening on the pump cover.
Embodiment
A kind of safety is regulated the integrated valve oil pump, and it is made up of the pump housing 1, pump cover 2, external rotor 3, internal rotor 4, hollow rotor shafts 5, drive sprocket 6 and safety regulating valve parts 7, and the pump housing 1 and pump cover 2 link together by bolt.Be provided with the rotor hole that is used for installing external rotor 3, internal rotor 4 and hollow rotor shafts 5 in the pump housing 1, rotor hole is provided with oil suction chamber 13 and goes out oil pocket 12.Be provided with modulating valve oil suction chamber 22 and modulating valve in the lid of pump cover 2 and go out oil pocket 23, modulating valve oil suction chamber 22 is corresponding with the oil suction chamber 13 in the pump housing 1, modulating valve go out oil pocket 23 with the pump housing 1 in to go out oil pocket 12 corresponding, mesh the tooth cavity of being gone by external rotor 3 with internal rotor 4 between them, respectively oil suction chamber 13, modulating valve in modulating valve oil suction chamber 22 and the pump housing 1 are gone out oil pocket 23 and be communicated with formation oil pump internal oil passages passage with the oil pocket 12 that goes out in the pump housing 1.External rotor 3 and internal rotor 4 are installed in the rotor hole on the pump housing 1, and hollow rotor shafts 5 is installed in the axis hole of the pump housing 1 and pump cover 2, and the middle part of hollow rotor shafts 5 is connected with internal rotor 4 interference, and the outer end press-fits sprocket wheel 6.
Be provided with a disjunctor valve opening 21 on pump cover 2, disjunctor valve opening 21 goes out oil pocket 23 with modulating valve oil suction chamber 22 and modulating valve and communicates.Be provided with safety regulating valve parts 7 in disjunctor valve opening 21, safety regulating valve parts 7 are made up of plunger 71, spring 72, fetal rhythm 73 and plug screw 74.Be provided with short piston 713 at plunger 71 front ends, tail end is provided with shell type piston 714, spring eye 711 and spill port 715, and spill port 715 communicates with spring eye 711, and the Transverse plane of short piston 713 is provided with oilhole 712.Plunger 71 is installed in the disjunctor valve opening 21, and spring 72 and fetal rhythm 73 are installed in the spring eye 711 of plunger 71, and plug screw 74 is installed in the port of disjunctor valve opening 21.Safety regulating valve parts 7 have formed a shoe cream room 24 and an annular oil cavity 25 after being installed in the disjunctor valve opening 21 in disjunctor valve opening 21, annular oil cavity 25 goes out oil pocket 23 with modulating valve and communicates.
Be installed in shell type piston 714 on the plunger 71 in the disjunctor valve opening 21 and can open or block the oil circuit that modulating valve oil suction chamber 22 and modulating valve go out oil pocket 23, go out the engine oil pressure of oil pocket 23 when too high at modulating valve, pressure oil will enter shoe cream room 24 along oilhole 712, promoting plunger 71 moves to spring 72 1 ends, thereby plunger 71 rear end shell type pistons 714 are progressively opened the passage of modulating valve oil suction chamber 22, at this moment too high pressure oil will directly go out oil pocket 23 from modulating valve, enter modulating valve oil suction chamber 22 through annular oil cavity 25, reach and reduce the pressure that modulating valve goes out oil pocket 23 inner machine oil.
Oilhole 712 on short piston 713 Transverse planes of plunger 71 front ends; be to make pressure machine oil enter bottom shoe cream room 24 along this oilhole; thereby promoting plunger 71 moves; solve pressure oil simultaneously when promotion plunger 71 is mobile in valve opening 21; make machine oil by this oilhole 712 time, play damping function; avoid plunger 71 to come and go producing when mobile impacting the safety of protection engine oil path system.
Spill port 715 on the shell type piston 714 on the plunger 71 makes plunger 71 coming and going when mobile too, produces damping and stabilization.
The fetal rhythm 73 of plunger 71 spring eyes 711, in order to keep spring 72 in frequent compression and springback process, deviation does not take place in the position of assurance plunger 71, prevents bending and influences the stability and the accuracy of its elastic force.
Safety provided by the invention is regulated the safety regulating valve parts 7 on the integrated valve oil pump, and the working procedure of regulating oil pressure when engine speed changes is:
1, when engine speed is low, it is less with the engine oil pressure difference of modulating valve oil suction chamber 22 that modulating valve goes out oil pocket 23, modulating valve goes out machine oil in the oil pocket 23 slightly to be promoted modulating valve plunger 71 and moves, and with spring 72 mild compression, modulating valve oil suction chamber 22 passages still are in and close not busy state, oil pump normal fuel injection.
2, increase gradually when engine speed, after acquiring a certain degree, the engine oil pressure difference that modulating valve goes out oil pocket 23 and modulating valve oil suction chamber 22 increases gradually, the machine oil that modulating valve goes out in the oil pocket 23 promotes the increase of plunger 71 mobile positions, and further with spring 72 compressions, the passage of modulating valve oil suction chamber 22 is opened gradually, modulating valve goes out the part machine oil in the oil pocket 23, enter modulating valve oil suction chamber 22 by opened passage, this moment, modulating valve went out the decline of oil pocket 23 engine oil pressures, thereby realized the regulating action of engine oil pressure.
3, when engine speed continuation increase, the main oil gallery engine oil pressure increases, the engine oil pressure difference that modulating valve goes out oil pocket 23 and modulating valve oil suction chamber 22 further strengthens, modulating valve goes out the increasing displacement that oil pocket 23 interior machine oil will further push away plunger 71, at this moment, the passage of modulating valve oil suction chamber 22 is further opened, and the machine oil increasing that modulating valve goes out in the oil pocket 23 flows to modulating valve oil suction chamber 22, thereby realizes reducing the purpose of engine oil pressure.
