Embodiment
Contrast accompanying drawing below, by description, the effect of the mutual alignment between the shape of the specific embodiment of the present invention such as related each member, structure, the each several part and annexation, each several part and working principle etc. are described in further detail embodiment:
As shown in Figure 1, the present invention is a kind of cooling oil duct structure for engine oil, comprise machine oil cooler 1, machine oil cooler oil duct 11, described engine oil cooling structure also comprises machine oil cooler module 4, machine oil cooler module oil duct 9 is set in the described machine oil cooler module 4, on the machine oil cooler module filler opening 8 of described machine oil cooler module oil duct 9 one-way valve 13 is set.
Described machine oil cooler module 4 is installed on the base of machine oil cooler 1.
On the machine oil cooler oil duct 11 of described machine oil cooler 1 low pressure check valve 5 is set, on the machine oil cooler module filler opening 8 of described oil cooler module 4 high pressure one-way valve 6 is set.
Described high pressure one-way valve 6 and low pressure check valve 5 all are arranged on the machine oil oil duct 10.
Described low pressure check valve 5 is set to from the structure of machine oil oil duct 10 1 side direction machine oil cooler filler openings 2 one sides unlatching; Described high pressure one-way valve 6 is set to from the structure of machine oil cooler module filler opening 8 one side direction machine oil oil ducts 10 1 sides unlatching.
Machine oil cooler module oil outlet 7 positions of described machine oil cooler module oil duct 9 are set to the structure that is communicated with the machine oil cooler oil outlet 3 of machine oil cooler oil duct 11.
Described machine oil cooler module oil outlet 7 and machine oil oil duct 10 all are communicated with oil leab on the cylinder body.
On described and the machine oil cooler module 4 that machine oil cooler 1 is connected seal groove 12 is set, seal rings are installed in the seal groove 12.
In the present invention, also comprise seal groove 12, because in the present invention, machine oil cooler 1 is parts, machine oil cooler module 4 is parts, machine oil will flow between module 4 and machine oil cooler 1, as not taking measures, machine oil can leak in this process, therefore to add seal groove 12 (do not show on the figure that this structure is used in the prior art in a large number, its effect is exactly in order to ensure the sealability between two links), seal groove 12 built-in seal rings (not showing on the figure) prevent lubricating oil leakage.
The present invention is a design seal groove 12 on module 4, by being assemblied in the seal ring in the seal groove 12, realizes being sealed and matched between module 4 and the oil cooler 1 then.
As required, seal groove 12 also can be arranged on the oil cooler 1.
Installation between module 4 and the oil cooler 1 generally is to install by bolt, and design has bolt hole on the oil cooler 1, by bolt oil cooler 1 is tightened on the module 4 then to get final product.
As shown in Figure 2, when the machine oil cooler 1 of cooling oil duct structure for engine oil of the present invention is in normal working, engine oil pressure in the machine oil oil duct 10 backs down low pressure check valve 5, at this moment, machine oil is by one-way valve 5, from entering the machine oil cooler oil duct 11 of machine oil cooler 1, cools off machine oil cooler filler opening 2, then, cooled machine oil flows out from machine oil cooler oil outlet 3, the oil leab that enters in the cylinder body by machine oil cooler module oil outlet 7 has so just been realized the cooling to machine oil again.
As shown in Figure 3, when the pressure drag in the machine oil cooler 1 is excessive, engine oil pressure in the machine oil oil duct 10 can't be fully or is all backed down low pressure check valve 5, therefore, the machine oil of this moment then changes by enter machine oil cooler module oil duct 9 from high pressure one-way valve 6, machine oil cooler module oil duct 9 and machine oil cooler module oil outlet 7 UNICOMs, therefore when pressure drag is excessive, part or most machine oil can be without machine oil cooler, enter machine oil cooler module oil duct 9 from high pressure one-way valve 6, and along the oil duct 9 direct oil leabs that enter to machine oil cooler module oil outlet 7 places in the cylinder body.
General design at present, be on the machine oil cooler module, to design a bypass valve and designing bleed off circuit, the present invention designs two one-way valves of high and low pressure dexterously at the filler opening place of machine oil cooler module, simplify bleed off circuit, make more compact structure, effectively save space and cost, easier manufacturing processing.
The present invention designs high pressure one-way valve 6, low pressure check valve 5 at machine oil cooler module filler opening 8 places, thereby utilizes the principle of high and low pressure to deal with problems.
When machine oil cooler was in normal working, low pressure check valve 5 was opened, and machine oil enters machine oil cooler 1 and cools off, and then enters the lubricated circulating oil path of engine cylinder-body by machine oil cooler module oil outlet 7 from machine oil cooler oil outlet 3;
When the pressure drag in the machine oil cooler 1 is big, high pressure one-way valve 6 is opened, machine oil enters from machine oil cooler module filler opening 8, flow to machine oil cooler module oil outlet 7 along machine oil cooler module oil duct 9, the lubricated circulating oil path of engine cylinder-body then, thus ensure to the enough engine oil supplying amounts of motor.
The problem that the present invention mainly solves is to solve the excessive harmful effect that causes of machine oil cooler pressure drag.
External and embedded machine oil cooler all can adopt structure of the present invention.
After the external machine oil cooler adopts structure of the present invention, only on the machine oil cooler seat, change a little, can improve the reliability of bypass function; Embedded oil cooler adopts, and simplifies the design of bleed off circuit, reduces the manufacturing difficulty, and cost falls in loss of weight.
Can cause the machine oil crushing to increase when the machine oil cooler pressure drag is excessive, engine oil flow is not smooth, influences the engine component life-span etc.The present invention increases high and low pressure valve simultaneously on the machine oil cooler cover plate, utilize the principle of high and low pressure to prevent a series of unfavorable conditions that the machine oil cooler internal resistance causes when excessive.
In conjunction with the accompanying drawings the present invention has been carried out exemplary description above; obviously the concrete realization of the present invention is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present invention and technological scheme to carry out; or design of the present invention and technological scheme are directly applied to other occasions without improving, all in protection scope of the present invention.
