Description
Technical field
The present invention relates to a kind of pump, You Zhike is the pump structure of multi-direction assembling according to the needs of different occasions.
Background technique
The structural form of society makes rapid progress, and the required quality of the life of people improves relatively, and also from the old thinking of " can with all right ", the quite exquisiteness that becomes has the conception of continuous progress or innovation only, could satisfy the demand of modern society to the requirement of things.
Please refer to U. S. Patent and number the 6th, 502, No. 394 " pump " be patent (PUMP), and be shown in Figure 1 as it, and this existing pump includes valve gap that a pump chamber, is connected in pump chamber, an and gear pump that is connected in valve gap.This valve gap is provided with two runners can establish the oil circuit pipeline to be connected in motor for connecing, and also is provided with hydraulic fluid port simultaneously on this valve gap and can establishes the oil circuit pipeline in oil feeder RES for connecing.As shown in Figure 2, this existing pump is on being installed in power car the time, usually with controlling rod one side of this pump chamber toward the outer side, manipulates being convenient for people to.But because the valve gap of this pump only has a kind of device direction with respect to this pump chamber, make the runner of this valve gap only can produce the piping method of single direction, and when giving pipe arrangement in this way, the oil circuit pipeline between two pumps about making and the oil feeder RES is too numerous and diverse.As shown in Figure 4,, then will connect and establish a U-shaped connecting rod, and to assembling quite trouble, and make and spend raising in the controlling rod of a pump wherein if when serve as the installing orientation with oil pipe circuit neat.
In order to improve the shortcoming of aforementioned existing structure, the someone designs the pump as Fig. 5, and it includes the valve gap that a pump chamber, is connected in pump chamber, and a gear pump that is connected in valve gap.This valve gap is provided with two runners can establish the oil circuit pipeline to be connected in motor for connecing, and also being provided with hydraulic fluid port simultaneously on this valve gap can be for being arranged in oil feeder RES.Shown in Fig. 4 to Fig. 4 B, this valve gap has the piping method of two kinds of directions, can solve the shortcoming of aforementioned existing structure.
Aforementioned existing structure still has shortcoming to exist in practicality, because this runner is located on this valve gap, so make that the variation of this pump on pipe arrangement is more dumb, two kinds of different pipe arrangement directions of tool only.And be subjected to stopping of obstacle when two runners and can't connect when establishing the oil circuit pipeline, then certainly will valve gap to be pulled down from pump chamber, the angle of rotation valve gap just can connect this two runners avoiding obstacles and establishes the oil circuit pipeline, but so make it comparatively bother, cause the greatly puzzlement of user at fit at fit on.And this existing structure can't produce the effect of multi-direction pipe arrangement when being applied to the assembling occasion of varying environment, a big defective of be using, and very impracticable of the design that this kind is not inconsistent the industry utilization is so there is necessity of improvement.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art and defective, propose a kind of pump structure, the technical problem that its desire solves is that the runner of existing pump is to be located on this valve gap, so make that the variation of this pump on pipe arrangement is more dumb, only two kinds of different pipe arrangement directions of tool.And be subjected to stopping of obstacle when runner and can't connect when establishing the oil circuit pipeline, then certainly will valve gap to be pulled down from pump chamber, the angle of rotation valve gap just can connect this runner avoiding obstacles and establishes the oil circuit pipeline, but so makes it comparatively bother at fit on, causes the greatly puzzlement of user at fit on.And this existing structure can't produce the effect of multi-direction pipe arrangement when being applied to the assembling occasion of varying environment, a big defective of be using, and this kind is not inconsistent very impracticable of design that industry utilizes, and the utmost point awaits improvement.
For reaching above-mentioned purpose, the invention provides a kind of pump structure, it comprises a pump chamber, a control lid and a multi-direction connecting cover; This control lid connects airtight the top side in this pump chamber, and this control is placed on an end and offers an oil-sucking hole, and this control is placed on a side and offers a draining hole; This multi-direction connecting cover connects airtight in the top side of this control lid, this multi-direction connecting cover can produce the assembling position of multiple different direction with respect to this control lid, offer two runners that run through two ends in this multi-direction connecting cover, this runner can provide the fluid of oil pressure actuated device to flow out respectively and flow into use, and an end of this runner can be installed a blocking and be sealed; Thus, this control lid and this multi-direction connecting cover can be assembled according to the needs of different occasions, can produce the effect of multi-direction pipe arrangement.
