Description
Technical field
The utility model belongs to field of internal combustion engine, and in particular to a kind of restriction of vibrating block-resistant.
Background technology
Fuel oil pumping action be fuel oil is suctioned out from fuel tank, pressurize after be transported in fuel feed pump, fuel pump and fuel oil pressure
Draught control mechanism coordinates sets up certain fuel pressure, and it is one of basic composition of electro jet car fuel injection system.EFI vapour
Electric elements needed for car fuel injection system are more, and in oil injection time, reaction has postponed, and also need to consume combustion during operation
Oil, increased the consumption of fuel oil.
Patent No. CN103270289A patent of invention discloses a kind of with by the combustion for internal combustion engine of pump operation
The pressure-regulating device of material spraying system, with a valve for being arranged on pump pressure side, the valve is used for the fuel under low pressure
The suction side for being on the pressure side drawn out to pump from pump, it is characterised in that arrange one in the suction side of pump and imitate with variable throttling
The variable restriction that answers, throttles so as to the fuel quantity to being conveyed to pump.Tied by machinery on the pump of fuel injection system
Constitutive element part provides the pressure of purely self-sufficient sum and adjusts, and not only achieves pressure by Function Coupling of the valve with variable restrictor portion
Decline and adjust, pump can also realize suction throttling, the demand of the amount of fuel injection and whole system according to the pressure of high-pressure area
Fuel consumption reduce due to lacking electric part.
Foregoing invention patent solves some problems, but is designed with certain defect, section in the internal duct of restriction
The design of stream portion interior groove is being integrally formed on steel construction, and whole oil circuit is thinner, if containing impurity in the middle of fuel oil, will make
Oil circuit is blocked, and the fuel oil circulation in the middle of oil circuit is not smooth, and the restriction of pump oil gas will fail, would not be with the effect of fuel oil throttling
Really, in the combustion process of next fuel oil, amount of fuel is difficult to control to, and the power performance of engine can be caused to weaken, operability
Can weaken.
Utility model content
The utility model is intended to provide a kind of restriction of vibrating block-resistant, to avoid in restriction oil circuit blocking, allows fuel oil
Good circulation is realized in restriction.
In order to achieve the above object, base case of the present utility model is as follows：A kind of restriction of vibrating block-resistant, including combustion
Oil adjusts pump, restriction, pump oil pipe and oil return pipe, and described oil return pipe one end is fixedly connected restriction, and the oil return pipe other end is fixed
Connection fuel oil adjusts pump, and the restriction is divided into low-pressure area, suction district and the regulating valve that slides in low-pressure area and suction district, institute
The one end for stating regulating valve is arranged in suction district, and the other end of regulating valve is arranged in low-pressure area, is provided with storage in the suction district
Grease chamber, oil-feed tank, pouring orifice, spill port, oil-recovery tank and oil outlet, the fuel oil adjust pump by pump oil pipe and restriction top
Pouring orifice be fixedly connected, the oil-feed tank, oil-recovery tank, spill port connect with accumulator respectively with oil outlet that to form cavity whole
Body, the regulating valve are oppositely arranged with pouring orifice, and the oil-feed tank is provided with the first groove, the second groove, first port and
Two-port netwerk, first groove are arranged in the first port of oil-feed tank, and second groove is arranged on the second end of oil-feed tank
On mouth, dismountable bellows in the oil-feed tank, is provided with, the bellows is provided with the 3rd port and the 4th port, the ripple
3rd port of line pipe is adapted with the first groove of oil-feed tank, and the 4th port of bellows is mutually fitted with the second groove of oil-feed tank
Should.
The principle of base case：When fuel oil adjusts pump and does not work, the top of regulating valve under the pressure effect of low-pressure area,
Regulating valve compresses pouring orifice.During operation, open fuel oil and pump adjusted, fuel oil adjusts pump and starts pump oil, and the oil pressure in pump oil pipe is raised,
In the presence of oil pressure, in low-pressure area, the pressure rise of low-pressure area, regulating valve are produced axially downwardly pressure transmission regulating valve
Displacement, fuel oil are entered in the middle of restriction from pouring orifice.When regulating valve top less than oil-feed tank opening when, fuel oil pass through into
The bellows arranged in oil groove is entered in the middle of accumulator, and the most of impurity in fuel oil is all stayed on bellows, in oil storage room
Fuel oil enter stage of next oil jetting combustion from oil outlet；When the fuel oil in oil storage room is excessive, fuel oil passes through oil-recovery tank
