Abstract
The utility model discloses a novel oil pipe is returned to back pressure formula comprises oil return joint, C shape return bend and U -bend, establish C shape return bend in returning oil pipe, stabilize the pressure that passes through in the oil pipe, establish the U -bend in returning oil pipe, guarantee the coolant oil and fill all the time in returning oil pipe, the oil return connects, transfers the volume of increasing the oil return, fixes back oil pipe, the utility model discloses a design adopts the step -length of adjustment return bend angle and oil return structure and return bend, controls back the pressure of the interior machine oil of oil pipe, can clean separation waste gas and machine oil accomplish the smooth backward flow of auxiliary cooling machine oil to the inefficacy that doping waste gas made the machine oil back flow velocity slow down when guaranteeing the backward flow of engine cooling machine oil increases the availability factor, low cost.
Description
(1) technical field
The utility model belongs to fuel engine technical field, is specifically related to novel return-pressure type return tube by adjustment bend pipe angle, carries out normality pressurize and prevent exhaust gas recirculation, hinder cooling machine oil backflow.
(2) background technique
In order to improve engine oil return efficiency, solving a kind of reduction engine cooling oil return efficiency, causing engine radiating difficulty, reduce the problem of engine operating efficiency.For this reason, by designing a kind of new structure adjusting the step-length of bend pipe angle and oil-returning structure and bend pipe, preventing engine cooling oil return from having some setbacks and causing various inefficacy.
(3) model utility content
The purpose of this utility model, is to provide a kind of return-pressure type return tube to improve the cooling action of engine motor oil, pressure when ensureing that machine oil refluxes, stops the phenomenon of doping waste gas in machine oil, enhance engine cooling efficiency.Main technical schemes is as follows:
A kind of novel return-pressure type return tube, is made up of back leakage connection, C shape bend pipe, U-bend; Establish C shape bend pipe in described return tube, stablize and pass through pressure in oil pipe; Establish U-bend in described return tube, ensure that cold oil is filled in return tube all the time, described back leakage connection, adjust and increase recirculating oil quantity, fixing return tube.
Design proposal of the present utility model adopts the step-length of adjustment bend pipe angle and oil-returning structure and bend pipe, control the pressure of return tube inner engine oil, the smooth backflow that supplement heat rejecter machine oil accomplished by waste gas and machine oil can be separated completely, thus the inefficacy that when ensureing the backflow of engine cooling machine oil, doping waste gas makes machine oil back-flow velocity slow down, increase utilization efficiency, the feature such as with low cost is apparent.
(4) accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
(5) embodiment
1, as shown in drawings, novel return-pressure type return tube, is made up of back leakage connection 1, C shape bend pipe 2, U-bend 3; Establish C shape bend pipe 2 in described return tube, stablize and pass through pressure in oil pipe; Establish U-bend 3 in described return tube, ensure that cold oil is filled in return tube all the time, described back leakage connection 1, adjust and increase recirculating oil quantity, fixing return tube; Design proposal of the present utility model adopts the step-length of adjustment bend pipe angle and oil-returning structure and bend pipe, control the pressure of return tube inner engine oil, the smooth backflow that supplement heat rejecter machine oil accomplished by waste gas and machine oil can be separated completely, thus the inefficacy that when ensureing the backflow of engine cooling machine oil, doping waste gas makes machine oil back-flow velocity slow down, increase utilization efficiency, the feature such as with low cost is apparent.
