During concrete use: hydraulic actuating cylinder rodless cavity, cylinder pressure rod chamber, annular seal space
As shown in Figure 8, step on the throttle pedal time, namely when compression stroke, now piston moves down.The volume reducing of hydraulic actuating cylinder rodless cavity, oil pressure raises, and flowing valve spring leaf is compressed, and fluid is pushed flowing valve open and flow to hydraulic actuating cylinder rod chamber.Because piston rod occupies cylinder pressure rod chamber segment space, the volume that therefore cylinder pressure rod chamber increases is less than the volume that rodless cavity reduces, so compression valve spring is compressed, rodless cavity part fluid just pushes compression valve open, flows back to annular seal space.And when violent accelerator pedal, because fluid can not flow to annular seal space rapidly, so Das Gaspedal will be limited in current location.
As shown in Figure 9, when unclamping Das Gaspedal, piston moves up, and hydraulic actuating cylinder rodless cavity oil pressure raises, and flowing valve is closed, and rebound valve spring is compressed, and the fluid in hydraulic actuating cylinder rodless cavity is pushed rebound valve open and flowed into cavity of resorption.Due to piston rod occupying parts partial volume so the fluid that hydraulic actuating cylinder rodless cavity stream comes is not enough to the volume being full of the increase of cylinder pressure rod chamber, cylinder pressure rod chamber is made to produce a degree of vacuum, at this moment throttle compensating valve spring leaf is compressed, and the fluid in annular seal space is pushed throttle compensating valve open and flow to hydraulic actuating cylinder rodless cavity and supplement.
The circulation passage number of rebound valve and throttle compensating valve is greater than the circulation passage number of flowing valve and compression valve, and such opening speed improves greatly, and can regulate with this diameter of opening to adapt to different stressed places.
