Technical solution is used by the utility model solves above-mentioned technical problem：
A kind of automobile ABS plunger pump, structure include plunger, baffle ring, pump seat and plug, and the baffle ring is hollow and both ends
It is provided with opening, the plunger is flexibly connected with one end open and realizes that liquid-tight envelope coordinates with opening, the pump seat and the other end
Opening connection simultaneously realizes that liquid-tight envelope coordinates with opening, is additionally provided with oil inlet on the baffle ring, the oil inlet passes through entrance list
It is connected to valve with fluid；The pump seat is fitted and connected plug, and the pump seat is equipped with oil outlet, and the plug was equipped with oil
Slot, the opening, oil outlet are connected to oil groove three excessively, and Outlet check valves are provided between the oil outlet and excessively oil groove.Pass through
Change the overall structure of plunger pump, realizes from baffle ring oil inlet, to simplify piston structure.
Further, further include plunger return spring, the plunger return spring one end is connect with plunger, the other end and gear
Circle or pump seat connection.By the way that plunger return spring is arranged, the cooperation difficulty of plunger and baffle ring is reduced, and can realize plunger
It automatically resets.
Preferably, the Outlet check valves are made of steel ball and one-way valve spring, the steel ball can be realized with oil outlet
Liquid-tight envelope cooperation, described one-way valve spring one end are connect with steel ball, and the other end is connect with plug.Steel ball and one-way valve spring composition
Check valve in automobile ABS plunger pump using easy to process, and durability is good.
Preferably, realizing that liquid-tight envelope coordinates by sealing ring between the plunger and opening, the sealing ring setting is being kept off
Circle outside.The setting of sealing ring improves the leakproofness between plunger and baffle ring, while reducing the cooperation between plunger and baffle ring and wanting
It asks.
Preferably, the oil groove of crossing is arranged on plug surface.Cross oil groove be arranged plug surface reduce plug plus
Work difficulty.
Preferably, the oil groove of crossing is damping hole.It sets mistake oil groove to damping hole and further simplifies former plunger pump
The middle damper for needing to be arranged, reduces processing cost.
The utility model compared with the existing technology has the following advantages and effect：By changing the overall structure of plunger pump,
It realizes from baffle ring oil inlet, to simplify piston structure.Pass through cooperation, steel ball and the one-way valve spring of plunger and plunger return bullet
Cooperation, sealing ring setting and cross oil groove concrete structure improve, further simplify the processing request of each component, reduce
Processing cost.In addition the more existing plunger pump bigger of volume that fluid can be stored in this structure guide ring, to improve plunger
The efficiency of pump.

Specific implementation mode
The utility model is described in further detail with reference to embodiment, following embodiment is to the utility model
Explanation and the utility model is not limited to following embodiment.
Embodiment 1：
As shown in Fig. 2, the present embodiment includes plunger 1, baffle ring 4, pump seat 7 and plug 10, baffle ring 4 is hollow and is provided at both ends with
Opening, 4 periphery of baffle ring are provided with oil inlet, and oil inlet is connected to by inlet one-way valve 11 with fluid.Plunger 1 is arranged in baffle ring 4
One end open in and the direction of motion limited by the plunger mat 5 in baffle ring 4, pass through capacity eccentric bearing (not shown) and one end and connect
It is connected on the plunger return spring 6 that the other end coordinates with plunger 1 on pump seat 7 (can also be connected to baffle ring 4), to realize that plunger 1 exists
Reciprocating motion in baffle ring 4, the outside of baffle ring 4 by being arranged sealing ring 3 and gasket 2 realizes liquid-tight envelope with plunger 1, pump seat 7 with
Another end opening of baffle ring 4, which is fixedly connected, realizes liquid-tight envelope, pump seat 7 and 10 snug fit of plug, is provided in pump seat 7 fuel-displaced
Mouthful, as shown in figure 5,10 surface of plug was provided with oil groove 12, crosses the structure setting of oil groove 12 and played when it being made to coordinate with pump seat 7
The effect of damping hole, above-mentioned opening, oil outlet and crosses oil groove 12 and is interconnected, but in its natural state, oil outlet and crosses oil groove
It is sealed by 10 steel ball 8 of plug between 12, steel ball 8 plays outlet unidirectionally by connecting the one-way valve spring 9 being arranged on plug 10
The effect of valve.
When plunger 1 is toward left movement, as shown in figure 3, the vessel in baffle ring 4 becomes larger, pressure is lower, and the fluid in master cylinder exists
Under the action of atmospheric pressure, open-top inlet one-way valve 11 flows into baffle ring 4.When plunger 1 turns right movement, as shown in figure 4, in baffle ring 4
Vessel become smaller, pressure increases, and the open-top steel ball 8 of fluid flows out from plug 10.So on circulate, the continuous pump of fluid is realized
Go out.
