Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention;
Accompanying drawing 2 regulates integrated valve modular construction schematic diagram for being arranged on the interior safety of disjunctor valve opening on pump cover.
Embodiment
A kind of oil pump with safety regulation integrated valve, 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, together with the pump housing 1 is bolted with pump cover 2.In the pump housing 1, be provided with the rotor hole for external rotor 3, internal rotor 4 and hollow rotor shafts 5 are installed, on rotor hole, be provided with oil suction chamber 13 and go out oil pocket 12.In the lid of pump cover 2, be provided with modulating valve oil suction chamber 22 and modulating valve 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, between them, engage the tooth cavity of being gone by external rotor 3 with internal rotor 4, respectively modulating valve oil suction chamber 22 and oil suction chamber 13, modulating valve in the pump housing 1 are gone out to oil pocket 23 and be communicated with the oil pocket 12 that goes out in the pump housing 1, form oil pump internal oil passages passage.External rotor 3 and internal rotor 4 are arranged in the rotor hole on the pump housing 1, and hollow rotor shafts 5 is arranged 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 outer end press-fits sprocket wheel 6.
On pump cover 2, be provided with a disjunctor valve opening 21, disjunctor valve opening 21 goes out oil pocket 23 with modulating valve oil suction chamber 22 and modulating valve and communicates.In disjunctor valve opening 21, be provided with safety regulating valve parts 7, 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 arranged in disjunctor valve opening 21, and spring 72 and fetal rhythm 73 are arranged in the spring eye 711 of plunger 71, and plug screw 74 is arranged on the port of disjunctor valve opening 21.Safety regulating valve parts 7 be installed to disjunctor valve opening 21 interior after, at an interior shoe cream room 24 and the annular oil cavity 25 of having formed of disjunctor valve opening 21, annular oil cavity 25 goes out oil pocket 23 with modulating valve and communicates.
Be arranged on shell type piston 714 on the plunger 71 in disjunctor valve opening 21 and can open or block modulating valve oil suction chamber 22 and modulating valve and go out the oil circuit of 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 one end, 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 the pressure that reduction modulating valve goes out oil pocket 23 inner machine oil.
The fetal rhythm 73 of plunger 71 spring eyes 711, in order to keep-spring 72, in frequent compression and springback process, there is not deviation in the position of assurance plunger 71, prevents bending and affect stability and the accuracy of its elastic force.
Safety regulating valve parts 7 on oil pump with safety regulation integrated valve provided by the invention regulate the working procedure of oil pressure to be in the time that engine speed changes:
1, in the time that engine speed is lower, it is poor less with the engine oil pressure of modulating valve oil suction chamber 22 that modulating valve goes out oil pocket 23, modulating valve goes out machine oil in oil pocket 23 slightly to be promoted modulating valve plunger 71 and moves, and by spring 72 mild compression, modulating valve oil suction chamber 22 passages are still in closing not busy state, oil pump normal fuel injection.
2, when engine speed increases gradually, after acquiring a certain degree, modulating valve goes out the poor increase gradually of engine oil pressure of oil pocket 23 and modulating valve oil suction chamber 22, the machine oil that modulating valve goes out in oil pocket 23 promotes plunger 71 mobile positions increases, and further spring 72 is compressed, the passage of modulating valve oil suction chamber 22 is opened gradually, modulating valve goes out the part machine oil in oil pocket 23, enter modulating valve oil suction chamber 22 by opened passage, now modulating valve goes out oil pocket 23 engine oil pressures declines, thereby realizes the regulating action of engine oil pressure.
3, when engine speed continues to increase, main oil gallery engine oil pressure increases, modulating valve goes out the poor further increasing of engine oil pressure of oil pocket 23 and modulating valve oil suction chamber 22, modulating valve goes out machine oil in oil pocket 23 will further push away the increasing displacement of plunger 71, now, the passage of modulating valve oil suction chamber 22 is further opened, and the machine oil increasing that modulating valve goes out in oil pocket 23 flows to modulating valve oil suction chamber 22, thereby realizes the object that reduces engine oil pressure.
