Description
(1) technical field:
The utility model relates to a kind of diesel filter for automatically removing air in the diesel car oil supply system.
(2) background technique:
Diesel-oil filter is the vitals in the diesel car oil supply system, and it mainly acts on is to guarantee supplying clean diesel oil, guarantees the works fine of motor.Common diesel-oil filter has case, has on the case into and out of hydraulic fluid port, and encloser inner wall is furnished with filter core, and oil outlet wherein is arranged on the top of case, and this simple and easy filter cleaner has only single filtering function.In a single day oil circuit in oil supply system enters air, and existing diesel-oil filter is done nothing, and because air is lighter, can be at first air-supplied to motor, have a strong impact on the work of motor.
(3) summary of the invention:
The purpose of this utility model is to solve existing diesel-oil filter function singleness, and problem that can not deaeration provides a kind of diesel filter for automatically removing air.
Concrete scheme of the present utility model is to improve at existing diesel-oil filter, the utility model includes case, case is provided with filler opening and oil outlet, be furnished with filter core along inwall in the case, case hollow partly is the reservoir compartment, it is characterized in that: oil outlet is provided in a side of the bottom of case, and is provided with relief opening at the top of case; Two float valves are installed in the reservoir compartment of case connect relief opening and oil outlet respectively, the float valve that wherein connects oil outlet has vertically arranged long tubular valve body, in the long tubular valve body ball float is housed, long tubular valve body upper end has main oil-feed port, and the lower end has the idling oil-feed port.
The main oil-feed port height of the float valve upper end that is connected with oil outlet described in the utility model is greater than 1/2 case height.
The main oil-feed port height of the float valve upper end that is connected with oil outlet described in the utility model is more preferably greater than 2/3 case height.
The float valve that is connected with oil outlet described in the utility model, it is feasible that the main oil-feed port height of upper end suitably reduces, but must not influence the required fuel delivery of automatic pump oil.
The utility model is simple in structure, does not change profile, is easy to safeguard, particularly when keeping ordinary diesel oil filter cleaner function, has increased the function of automatically removing air, and follow-up high pressure oil pump and motor are played a good protection.
(4) description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Among the figure: 1-filler opening, 2-filter core, 3-reservoir compartment, 4-idling oil-feed port, 5-master's oil-feed port, 6-oil outlet, 7, the 8-ball float, 9-relief opening, 10-float valve, 11-float valve, 12-case.
(5) embodiment:
Referring to accompanying drawing: the utility model cylindrical shape case 12, case 12 upper portion side wall are provided with filler opening 1, and case 12 inner wall surroundings are furnished with filter core 2, and the hollow of case 12 partly is reservoir compartment 3, particularly: establish relief opening 9 at the top of case 12, and set out hydraulic fluid port 6 in the bottom; And float valve 10 (it is to place a ball float 8 in a short cylinder shaped valve body) connection relief opening 9 is installed in the reservoir compartment 3 of case 12, float valve 11 is installed is connected oil outlets 6.Wherein float valve 11 has long tubular valve body, in long tubular valve body, be placed with ball float 7, be provided with main filler opening 5, be positioned at 3/4 of case and highly locate in the upper end of long tubular valve body, general main filler opening 5 is not less than 1/2 case height, minimumly must not influence the required fuel delivery of automatic pump oil.Lower end at long tubular valve body is provided with idling filler opening 4, promptly constitutes the utility model.
The working principle of the utility model under different operating modes is summarized as follows:
One, its working principle during the pipeline road nominal situation: this filter cleaner is contained in the front end of high pressure oil pump, and after the secondary diesel-oil filter, oil outlet 6 is a little more than high pressure oil pump.Diesel oil sees through filter core 2 by filler opening 1 and enters reservoir compartment 3 under the oil transfer pump effect, and through idling oil-feed port 4 and main oil-feed port 5, oil outlet 6 is to the high pressure oil pump fuel feeding, and fuel delivery maximizes.This moment, ball float 7,8 floated, and 7 are beneficial to normal fuel injection up, and ball float 8 floats blocks relief opening 9, kept charge oil pressure in the reservoir compartment, and fuel feeding is unimpeded.
Two, when the pipeline road seepage enters air; Air and diesel oil together enter in the reservoir compartment 3, and air separates in the reservoir compartment with diesel oil, and air up, diesel oil below, oily plane descends a little, ball float 7 descends a little, also do not influence main oil-feed port 5 fuel feeding, ball float 8 descends, and opens relief opening 9, air is discharged from, rising rapidly again in the oil plane, though fuel feeding has a little fluctuation, can keep the required fuel delivery of motor, start the function proper functioning, Here it is this device overcomes and gets rid of function automatically oil path failure.
Three, when not having diesel oil in the pipeline road, oil transfer pump can only pump air in the reservoir compartment 3, oil is reduced to main oil-feed port 5 under the plane, and main oil-feed port 5 fuel cut-offs have only idling oil-feed port 4 to high pressure fuel supply pump, motor can only idle running, remind the driver to have refueled and maybe will get rid of oil path failure, at this moment, ball float 8 falls, open relief opening 9, air is got rid of automatically.Diesel oil in the reservoir compartment 3 can be kept engine idling operation about 15 minutes, if in time refuel or fix a breakdown this moment, reset motor, about 1 minute of idle running, diesel oil pumps into reservoir compartment 3 again under the oil transfer pump effect, and along with rising on the oily plane, main oil-feed port 5 begins fuel feeding again, ball float 8 rises and blocks air outlet 9, and motor recovers proper functioning.Utilize engine idle pump oil in this link, must manual pumps oil, the prompting warning function of Here it is this equipment, automatic pump functional oil.
Four, there is not diesel oil and motor when continuing when long idle running when pipeline road; oily plane descends near idling oil-feed port 4 in the reservoir compartment 3; ball float 7 descends with oily plane; then blocked oil outlet 6; stop to the high pressure oil pump fuel feeding; engine misses have been protected not enter air in the high pressure oil pump, the fuel cut-off protective function of Here it is this equipment.
