Description
Technical field
The utility model relates to a kind of pump cover be applied in oil pump, and particularly one is easy to use, and structure is simple, the pump cover be applied in oil pump of diverse in function.
Background technique
Oil pump serves conclusive effect in the middle of whole engine lubrication, and it provides the machine oil of enough pressure and flow for whole motor, and to ensure that each friction member is lubricated fully, the pressure part that protection is relevant is not damaged.Oil pump generally includes the pump housing, gear assembly, driving shaft, pump cover, and the working principle of oil pump is: when the engine operates, and the timing gear of bent axle drive oil pump to rotate.Rotor tooth form designs make rotor forward any position to, and gear line can become point cantact mutually.Like this, just form closed chamber between inside/outside rotor, when turning over from filler opening, volume increases, and produce degree of vacuum, machine oil just sucks through filler opening; When the chamber and oil outlet that suck machine oil are connected, the volume in chamber reduces, and oil pressure raises, and machine oil extrudes from oil outlet.Motor ceaselessly operates, and oil pump also ceaselessly operates, and forces machine oil by the path circulation of regulation.
Pump cover is the assembly for closing machine pump body, usually only has sealing process, and on the pump housing, be provided with pressure stable hole, sets up separately pressure stable hole not only can make user's operate miss when carelessness, and sets up separately pressure stable hole that cost can be caused higher.On the other hand, usually will grasp the shade of pump cover when extract pump cover, and in order to easy for installation, it is enough thin that the shade of pump cover can do, so be difficult to extract.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of easy to use, and structure is simple, the pump cover be applied in oil pump of diverse in function.
For solving the problems of the technologies described above, the closure member that the utility model comprises block and is fixedly connected with block, pumping holes close-fitting in described closure member and oil pump, it is characterized in that: described closure member inside hollows out formation cavity, and be provided with a piston body in this cavity, size and shape and the cavity phase close-fitting of described piston body, the length of described piston body is longer than closure member, and the top of piston body extends to block place, described closure member outside side wall is circumferentially with circle first restraining groove, described restraining groove is provided with cleaning unit.
After have employed said structure, closure member hollows out and is provided with piston body in cavity, because piston body can free slippage in closure member, and closure member hollows out rear pump body can be connected with external environment condition, so, when needs voltage stabilizing, only piston body need be taken out, just the effect of voltage stabilizing can be played, and on the other hand, due to the structure of pump cover, be very easy in the closure member that some spots are residued on pump cover, after in closure member, cleaning unit is set, can while taking-up piston body, the cleaning pump housing and closure member.
As further improvement of the utility model, described cleaning unit comprises rubber ring, and circumference is located at the bristle outside rubber ring, and the minimum diameter that described rubber ring is not stretched is less than the diameter of restraining groove.
After have employed said structure, the simple bristle that uses can realize the technique effect cleaned, and can effectively be attached on the first restraining groove due to the physical property of rubber ring.
As further improvement of the utility model, circle second restraining groove is installed with according to the shape circumference of piston body outside described piston body, described second restraining groove is provided with a seal ring, and described seal ring and piston body match free slippage in the cavity that merges and can be placed in closure member.
After have employed said structure, piston body can easily in closure member slippage and the setting of seal ring add the sealing of the pump housing greatly.
As further improvement of the utility model, described pull unit is the draw ring that two ends are fixedly arranged on block top, and described draw ring lies against block top, and is respectively provided with a buckling groove be connected in by draw ring on block in draw ring both sides.
After have employed said structure, pump cover can pull out by draw ring easily.

Embodiment
As shown in Figure 4 and 1, the closure member (2) that this pump cover comprises block (1) and is fixedly connected with block, described closure member (2) and the pumping holes close-fitting in oil pump, described closure member (2) inside hollows out formation cavity, and be provided with a piston body (3) in this cavity, size and shape and the cavity phase close-fitting of described piston body (3), the length of described piston body (3) is longer than closure member (2), and the top of piston body (3) extends to block (1) place, described closure member outside side wall is circumferentially with circle first restraining groove (4), described restraining groove is provided with cleaning unit.
As shown in Figure 2, piston body (3) outside is installed with circle second restraining groove (5) according to the shape circumference of piston body, described second restraining groove (5) is provided with a seal ring (6), and described seal ring (6) and piston body (3) match free slippage in the cavity that merges and can be placed in closure member.
As shown in Figure 3, block (1) top of pump cover is installed with a draw ring (7), and described pull unit can pull pump cover to shift out from pumping holes.Described draw ring (7) lies against block top, and is respectively provided with a buckling groove (8) be connected in by draw ring on block (1) in draw ring (7) both sides.
As shown in Figure 4, described cleaning unit comprises rubber ring, and circumference is located at the bristle (9) outside rubber ring, and the minimum diameter of described rubber ring is less than the diameter of the first restraining groove.
During use, hollow out due to closure member and be provided with piston body in cavity, because piston body can free slippage in closure member, and closure member hollows out rear pump body can be connected with external environment condition, so, when needs voltage stabilizing, only piston body need be taken out, just the effect of voltage stabilizing can be played, and on the other hand, due to the structure of pump cover, be very easy in the closure member that some spots are residued on pump cover, after in closure member, bristle is set, can while taking-up piston body, the cleaning pump housing and closure member.Arranging of draw ring can make people easily pump cover be pulled out the pump housing.
