Specific embodiment
For the content of the invention, feature and effect of the present invention can be further appreciated that, following examples are hereby enumerated, and coordinate accompanying drawing
Describe in detail as follows.
The present invention is explained in detail for the structure of the check valve of Retarder of connecting with reference to Fig. 1.It is a kind of
For the check valve of Retarder of connecting, including valve seat 1, the valve seat 1 is fixed on upper fixed seat 7, fixed seat 7
Lower end is fixedly connected by welding with valve body 4, and the lower end of the valve seat 1 is connected with the oil-in 9 in the valve body 4, the valve body 4
The internal lower end of oil-in 9 is provided with valve element 2, and the valve element 2 is smooth ball, the valve element 2 with diameter greater than oil-in 9
Diameter, the lower end of the valve element 2 is fixedly connected by welding with spring 3, and the interior lower end of the valve body 4 is oil-out 10, described
The other end of spring 3 is fixedly connected with the upper end of the oil-out 10, and spring 3 does not affect the flowing of oil, and the lower end of the valve body 4 is with
Fixed seat 11 is fixedly connected by welding, and fixed seat 7 and the upper end of the lower fixed seat 11 are provided with bolt hole 12, it is described on
Bolt hole 12 in fixed seat 7 and the lower fixed seat 11 is respectively provided with 4, and the upper end of fixed seat 7 is solid with the retarder
Reservation 6 is fixed in bolt hole 12 by bolt 8 and is fixedly connected, and the upper end of retarder fixed seat 6 passes through with retarder housing 5
It is welded and fixed connection.
A kind of check valve for Retarder of connecting, including valve seat 1, valve element 2, spring 3, valve body 4, valve seat 1 is installed
On the oil input channel of retarder housing 5, and valve seat 1 is fitted close with retarder housing 5, and valve seat 1 simultaneously supports spring 3, valve element 2, valve
Body 4 is installed on integrally formed one unidirectional self-contr ol function；When retarder is started working moment, closed check valve, its closing
Purpose be to prevent oil road of the hydraulic oil from the working chamber that trapped fuel room is formed by rotor and stator from entering working chamber,
Because it is poor that hydraulic fluid pressure is not also formed in the working chamber that the moment rotor started working and stator are formed, if hydraulic pressure
Oil road of the oil from the working chamber that trapped fuel room is formed by rotor and stator enters the working chamber that rotor is formed with stator
It is interior to produce pressure differential, so as to be that retarder Medium Oil produces circulation, so now check valve needs to close, unidirectionally
Retarder medium is entered back into rotor into after stator oil input channel and is determined by trapped fuel room through grease chamber housing oil input channel after valve is closed
So as to produce pressure differential in the working chamber that son is formed, pressure differential enough opens check valve, and the Medium Oil for flowing through check valve is entered
Again by oil input channel inflow work after heat exchanger, an one-way hydraulic oil combination circulation is material is thus formed, so as to being slow
Constantly work makes automobile constantly slow down or constant speed to device;The cooperation that the present invention passes through valve element 2 and spring 3, prevents hydraulic oil from depositing
The oil road that grease chamber passes through in the working chamber that rotor is formed with stator enters working chamber；Valve body 4 protect internal structure from
The interference of external environment condition, it is ensured that the normal work of check valve；Valve seat 1 is used to support the position of valve element 2, and constitutes sealing pair,
Prevent the generation of check valve oil leakage phenomenon；Valve body 4 controls the basic function of oily flow by the movement of valve element 2, and valve element 2 is single
To the core component of valve；Movement to valve element 2 is realized by the compression of spring 3, so as to control the size of flow；Upper fixed seat 7
The fixation to check valve is realized with lower fixed seat 11, it is ensured that the normal work of check valve.
The above is only, to presently preferred embodiments of the present invention, any pro forma restriction not to be made to the present invention,
Every technical spirit according to the present invention is belonged to any simple modification made for any of the above embodiments, equivalent variations and modification
In the range of technical solution of the present invention.
