Abstract
The utility model relates to an engine oil pump cover. The inner side surface of the cover body is provided with an oil distributing ring which comprises a high pressure oil chamber and an oil suction chamber. The external side of the oil suction chamber of the oil distributing ring is provided with a sealing groove. The engine oil pump cover has the advantages of excellent sealing property and totally elimination to the probability that the air is sucked into the oil suction chamber. The engine obtains high-quality lubrication at any time and furthermore the reliability of the operation of the engine is guaranteed.
Description
Technical field
The utility model relates to a kind of oil pump, particularly a kind of oil pump cover.
Background technique
Motor is the heart of automobile, and can the performance of motor obtain fully playing and the working life that reach expected design, then the lubrication system of motor will play crucial effects, particularly the bearing shell of bent axle must keep enough lubricating constantly, even lubricated bad or oil starvation of short duration just may cause performance to reduce even tile kilning causes engine failure.Yet the quality of lubrication system performance is said and is depended on the machine oil pump performance in certain meaning.Although traditional oil pump is continued to use the lubricating requirement that satisfies motor for many years substantially, but also exist between oil pump cover and the pump housing that it matches sealing undesirable, cause air to be inhaled in the oil sucting cavity of pump, make the machine oil foamed and reduce the defective not fully up to expectations of lubricating quality.So exist described shortcoming to be because pump cover and the pump housing, inner and outer rotors do not form due to the Seal cage after assembling, the result of the structural measure of sealing promptly be not set on the fitting surface of pump cover inboard.
The model utility content
The utility model provides a kind of good seal performance at above-mentioned problems of the prior art, can prevent effectively that air is sucked into oil sucting cavity, improves and improve the oil pump cover of engine lubrication quality.
The purpose of this utility model realizes by the following technical solutions:
Cast out distribution oil ring on lid, distribution oil ring comprises high-voltage oil cavity and oil sucting cavity.The outside of oil sucting cavity in distribution oil ring is provided with a sealed groove.
The two ends of described sealed groove communicate with high-voltage oil cavity, and oil sucting cavity is included in wherein.
The utility model has the advantages of as follows:
The utility model compared with prior art, be provided with the structure of the sealed groove that two ends communicate with high-voltage oil cavity in the outside of the oil sucting cavity of distribution oil ring, this sealing configuration measure has good airproof performance through evidence, eliminate the defective that air is inhaled into oil sucting cavity fully, it is high-quality lubricated that motor is obtained constantly, and then guarantee the reliability of engine operation.
Description of drawings
Fig. 1 is a main TV structure schematic representation of the present utility model.
Among the figure, 1. high-voltage oil cavity, 2. sealed groove, 3. oil sucting cavity.
Embodiment
Embodiment
Content of the present utility model is described in detail in conjunction with the accompanying drawings by embodiment.
Lid as shown in Figure 1 is by casting, and its inner side surface is provided with distribution oil ring, comprises high-voltage oil cavity 1 and oil sucting cavity 3, is provided with the sealed groove 2 that two ends communicate with high-voltage oil cavity 1 in the outside of oil sucting cavity 3.This pump cover and the pump housing, the common Seal cage that forms in inner and outer rotors assembling back.When oil pump is worked, by between oil sucting cavity 3 and ambient air, introducing pressure oil, thereby avoid air is sucked in the oil sucting cavity 3, eliminate the defective that prior art exists fully.
Claims (2)
1. oil pump cover, the inner side surface of lid is provided with distribution oil ring, comprises high-voltage oil cavity (1) and oil sucting cavity (3), it is characterized in that the outside of the oil sucting cavity (3) at distribution oil ring, and a sealed groove (2) is set.
2, oil pump cover according to claim 1 is characterized in that described sealed groove (2) communicates with high-voltage oil cavity (3), and oil sucting cavity is included in wherein.
