In conjunction with above embodiment, the present invention mainly contains two processes, is respectively described below:
Oil-filled exhaust process:
As shown in Figure 1, be Medium Oil 14 in the clutch release slave cylinder 101, Medium Oil 14 is filled with inner chamber of cylinder block 13 from cylinder body 15 bottoms during oil-filled exhaust, and the air of inner chamber of cylinder block 13 is discharged from the exhaust passage 11 of filling of upper end cap 12.Filling exhaust passage 11 is connected with high pressure valve 3.The open and close that exhaust passage 11 is filled in high pressure valve 3 controls, and the reliable sealing under the realization superhigh-pressure high-temp.In conjunction with shown in Figure 2, high pressure valve passage A32 is communicated with pipeline 2 with temporary fuel tank 10 bottoms, and temporary fuel tank 10 tops are equipped with gas control shutoff valve 8, and gas control shutoff valve 8 is in normally open, and the air that clutch release slave cylinder 101 is discharged is finally discharged thus.
After clutch release slave cylinder 101 interior air are discharged fully, after Medium Oil 14 is full of cylinder body 15, can continue to outbound flow along the exhaust passage 11 of filling of upper end cap 12, the final inflow in the temporary fuel tank 10 stored, on the temporary fuel tank 10 liquid-level switch 1 is installed, triggers liquid-level switch 1 after discharging certain gauging, whether discharge fully with these air of differentiating in the clutch release slave cylinder 101, and according to the closing of the level switch signal control high pressure valve 3 of setting, block and seal and fill exhaust passage 11.
Inflation oil extraction process:
During clutch release slave cylinder 101 inflation oil extraction, Medium Oil 14 is discharged from cylinder body 15 bottoms.For accelerating oil extraction efficient, can in cylinder body 15, be filled with pressurized air by the exhaust passage 11 of filling on the upper end cap 12, force under pressure Medium Oil 14 to be discharged quickly.Pressurized air is entered by compressed air interface 6, realize regulating and controlling by solenoid valve B5, one-way valve 7, quick inserting joint 9 with temporary fuel tank 10, after solenoid valve B5 connected pressurized air, control system promoted spool 23 actions by solenoid valve A4 control cylinder 17, makes high pressure valve 3 be in opening state.Gas control shutoff valve 8 is closed simultaneously, thereby makes temporary fuel tank 10 form a seal container, and the Medium Oil 14 that at first will keep in the fuel tank when pressurized air is filled with temporary fuel tank 10 pushes back clutch release slave cylinder 101, reaches the purpose of recycling Medium Oil 14.
After Medium Oil 14 is discharged from clutch release slave cylinder 101 fully, this moment is because compressed-air actuated existence, still be in high pressure conditions in the clutch release slave cylinder 101, can not open upper end cover 12, pressure in the clutch release slave cylinder 101 must be dropped to normal pressure, control system this moment switching solenoid valve B5 again cuts off pressurized air gas control shutoff valve 8 is opened, be communicated with atmosphere, make the pressure in the clutch release slave cylinder 101 be reduced to rapidly normal pressure.
Each embodiment adopts the mode of going forward one by one to describe in this specification, and what each embodiment stressed is and other embodiment's difference that identical similar part cross-references gets final product between each embodiment.
" embodiment " who speaks of in this manual, " another embodiment ", " embodiment ", etc., refer to specific features, structure or the characteristics described in conjunction with this embodiment and be included among at least one embodiment that the application's generality describes.A plurality of local appearance statement of the same race is not necessarily to refer to same embodiment in specification.Furthermore, when describing a specific features, structure or characteristics in conjunction with arbitrary embodiment, what advocate is to realize that in conjunction with other embodiments this feature, structure or characteristics also fall within the scope of the invention.
Although invention has been described with reference to a plurality of explanatory embodiments of the present invention here, but, should be appreciated that those skilled in the art can design a lot of other modification and mode of executions, these are revised and mode of execution will drop within the disclosed principle scope and spirit of the application.More particularly, in the scope of, accompanying drawing open in the application and claim, can carry out multiple modification and improvement to constituent elements and/or the layout of subject combination layout.Except modification that constituent elements and/or layout are carried out with improving, to those skilled in the art, other purposes also will be obvious.
