Description
Technical field
This utility model is related to a kind of control electromagnetic valve controlling lubricating oil pump output oil pressure, particularly a kind of hydraulic buttery valve
Oil channel structures.
Background technology
Hydraulic regulating valve is installed on the engine oil passage of electromotor, for adjusting what lubricating oil pump exported to hydraulic element
Engine oil pressure.Hydraulic regulating valve is provided with oil-in, oil-out and oil return opening, is believed according to the control that engine control system sends
Number carry out the electromagnetic force size of precise control electromagnetic actuators, drive the movable valve plug in body cavity to carry out axially-movable, adjust into
The connected state of hydraulic fluid port, oil-out and oil return opening, thus the output oil pressure of lubricating oil pump is adjusted to target oil pressure, improves machine oil
The service behaviour of pump and hydraulic element and functional reliability, reduce the power attenuation of lubricating oil pump, lift engine power, fall
Low burn oil consumption and exhaust emissions.Hydraulic element carries out real-time dynamic control according to the Operation Conditions of electromotor, starts
The change of machine Operation Conditions can lead to the fluctuation of lubricating oil pump output oil pressure, and the dynamic response performance of hydraulic regulating valve has influence on machine oil
The job stability of pump and hydraulic element and reliability, The faster the better to usually require that the response speed of hydraulic regulating valve.
In hydraulic regulating valve, the efficiency that the oil charging structure in oil channel structures runs on regulating valve has critical impact.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model aims to provide a kind of oil channel structures of hydraulic buttery valve,
The machine oil entering electromagnetic valve is filtered and is guided.
For achieving the above object, this utility model adopts the following technical scheme that：
A kind of oil channel structures of hydraulic buttery valve, including valve body, this valve body one end is provided with oil-in, and this oil-in passes through
Filter screen connection is arranged at the oil suction chamber in valve body, valve body is located at place inside oil-in and is relatively set with two installing holes, an axle
It is individually fixed in this two installation in the holes to the two ends of spacer pin, drainage screen is connected to this axial limiting pin through a filter screen back-up ring
On.
As of the present utility model a kind of improve, be additionally provided with oil-feed valve seat in valve body, positioned at oil-in and oil suction chamber it
Between oil-feed valve seat in be provided with the oil inlet passage of connection oil-in and oil suction chamber, the bottom end face of this oil-feed valve seat was connected to
Filter screen is away from the side of oil-in.
The beneficial effects of the utility model are：By arranging drainage screen, filter to entering the machine oil in electromagnetic valve,
Oil flow rate is played with certain metering function simultaneously；Setting axial limiting pin, realizes the axial direction to drainage screen and filter screen back-up ring
Spacing and fixing, improve the steadiness of structure；By arranging oil-feed valve seat and arranging oil inlet passage in oil-feed valve seat, realize
Guiding to machine oil, and avoid machine oil directly to enter oil suction chamber, lead to oil flow rate excessive from oil-in and affect electromagnetic valve
Operational efficiency and control accuracy.

Specific embodiment
Below, in conjunction with accompanying drawing and specific embodiment, this utility model is described further：
As shown in figure 1, a kind of oil channel structures of hydraulic buttery valve, including valve body 1, this valve body 1 one end is provided with oil-in
11, this oil-in 11 is arranged at the oil suction chamber 12 in valve body 1 through drainage screen 2 connection, and valve body 1 is located at phase at oil-in 11 inner side
To being provided with two installing holes 6, the two ends of an axial limiting pin 4 are individually fixed in this two installing holes 6, and drainage screen 2 is through one
Filter screen back-up ring 3 is connected on this axial limiting pin 4.It is additionally provided with oil-feed valve seat 5, positioned at oil-in 11 and oil suction chamber in valve body 1
It is provided with the oil inlet passage 51 of connection oil-in 11 and oil suction chamber 12, the bottom of this oil-feed valve seat 5 in oil-feed valve seat 5 between 12
End face is connected on the side away from oil-in 11 for the drainage screen 2.
When this utility model uses, machine oil enters in valve body 1 by oil-in 11, and machine oil is after drainage screen 2 filtration through entering
Oily passage 51 enters oil suction chamber.
It will be apparent to those skilled in the art that can technical scheme as described above and design, make other various
Corresponding change and deformation, and all these change and deformation all should belong to the protection of this utility model claim
Within the scope of.
