In addition, the oil drainage hole is a hole with a circular cross section. The utility model discloses an oil drainage hole is opened in the position of variable feedback oil pocket, will follow the pressure oil of pump export seepage to variable feedback oil intracavity and arrange away to effectively eliminate the phenomenon appearance that the pressure oil that the variable slider received the seepage to come influences the production unexpected variable.
Description
Technical Field
The utility model relates to an internal-combustion engine lubricating system especially indicates a prevent vane pump of variable disturbance.
Background
Pressure oil of a variable feedback oil cavity on an existing vane pump usually comes from a main oil channel, pressure of the pressure oil from the main oil channel is attenuated after the pressure oil is filtered by a machine cooler, so that oil pressure in the variable feedback oil cavity is lower than that of an outlet of the pump, high-pressure oil at the outlet of the pump easily leaks to the variable feedback oil cavity through an end face gap, extra pressure is generated in the variable feedback oil cavity, the extra pressure and the pressure oil from the main oil channel act on a variable slider together to perform variable, and variable inaccuracy occurs, such as the phenomena of not according to expected variable, variable advance and the like.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a can be with the impeller pump of preventing variable interference that pump export seepage to the pressure oil drainage of variable feedback oil pocket was removed.
In order to solve the technical problem, the utility model discloses a following technical scheme: the variable interference prevention vane pump comprises a pump body, a variable slider and a variable spring, wherein a variable feedback oil cavity is arranged between the pump body and the variable slider, and an oil drainage hole for discharging redundant oil in a cavity is formed in the position, located in the variable feedback oil cavity, of the pump body.
Furthermore, the oil drain hole is formed in one end, close to the variable spring, of the variable feedback oil cavity and communicated with the oil inlet of the vane pump.
Or the oil drainage hole is formed in the middle of the variable feedback oil cavity and communicated with the main oil duct.
Preferably, the oil drainage hole is a hole with a circular cross section.
In traditional vane pump, the pressure oil of pump export passes through the end face clearance seepage to the variable feedback oil pocket in, makes the interior extra pressure that produces of variable feedback oil pocket, the utility model discloses to this problem, the ingenious draining hole that can subdue this extra pressure is seted up in the position that lies in the variable feedback oil pocket on the pump body, particularly, this draining hole can introduce oil inlet or main oil duct with the unnecessary pressure oil in the variable feedback oil pocket for the pressure oil in the variable feedback oil pocket keeps dynamic balance, avoids the pump export to produce the oil pressure of going out through the end face clearance seepage and disturbs to the oil pressure in the variable feedback oil pocket, thereby makes variable displacement vane pump realize accurate variable.

Detailed Description
In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplification of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.
In the description of the present invention, it should be noted that, unless otherwise specified and limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, mechanically or electrically connected, or interconnected between two elements, directly or indirectly through intervening media, and the specific meaning of the terms may be understood by those skilled in the art according to their specific situation.
As shown in fig. 1, the variable disturbance prevention vane pump comprises a pump body 1, a variable slider 2 and a variable spring 3, wherein a variable feedback oil cavity 4 is arranged between the pump body 1 and the variable slider 2, and an oil drainage hole 5 for discharging redundant oil in a cavity is formed in the pump body 1 at the position of the variable feedback oil cavity 4.
The vane pump of preventing variable interference among the above-mentioned embodiment, to the problem that "the pressure oil of pump export that traditional vane pump exists makes extra pressure produce in the variable feedback oil pocket through the end clearance seepage to the variable feedback oil pocket", ingenious set up one in the variable feedback oil pocket 4 and can subdue this extra pressure's draining hole 5, the size of this draining hole 5 is decided according to the volume of end clearance seepage fluid, for convenient processing, this draining hole 5 designs for the circular shape hole of cross section one-tenth, this draining hole 5 can be with unnecessary pressure oil in the variable feedback oil pocket 4 away, make the pressure oil of variable feedback oil intracavity keep dynamic balance, the fluid of avoiding pump export to produce the interference to the oil pressure in the variable feedback oil pocket through the end clearance seepage, thereby make variable displacement vane pump realize accurate variable.
When oil is discharged, the oil drain hole 5 may drain oil into an oil inlet cavity of the vane pump, that is, the oil drain hole 5 is communicated with an oil inlet of the vane pump, as shown in fig. 1, the oil inlet cavity of the vane pump is located at one side of the variable spring 3, and therefore, in this case, the oil drain hole 5 is preferably provided at one end of the variable feedback oil cavity 4 close to the variable spring 3.
When oil is discharged, the oil drain hole 5 can also drain oil to a main oil gallery of a lubricating system of the internal combustion engine, namely the oil drain hole 5 is communicated with the main oil gallery, and under the condition, the oil drain hole 5 can be arranged in the middle of the variable feedback oil cavity 4.
The above-mentioned embodiment is the utility model discloses the implementation scheme of preferred, in addition, the utility model discloses can also realize by other modes, any obvious replacement is all within the protection scope of the utility model under the prerequisite that does not deviate from this technical scheme design.
In order to make it easier for those skilled in the art to understand the improvement of the present invention over the prior art, some drawings and descriptions of the present invention have been simplified, and in order to clarify, some other elements have been omitted from this document, those skilled in the art should recognize that these omitted elements may also constitute the content of the present invention.
