Fig. 9 illustrates the hydrostatic actuator 1 being in original position, and wherein at pressure chamber A.1 active cylinder piston 18 starts
Middle structure pressure.In original position, the depressed part of the active cylinder piston 18 although drivening piece 20.6 of vent piston 20 reclines
18.4a, but vent piston 20 does not shifts.Therefore, the sealing function of vent piston 20 is corresponding to the function in Fig. 8.Initial
Between terminal position shown in position and Fig. 8, handle rubbing of Fig. 1 under normal circumstances and in the case of there is no venting process
Wipe clutch 23.
If venting process to be performed and the position to manipulation cylinder piston 18 carry out reference or credible test, then first
First move to the zero position shown in Figure 10.Active cylinder piston 18 is moved towards the direction of energy storage device 14 at this, until actively
Cylinder piston 18 reclines energy storage device 14.The inspection of this zero position is carried out by means of the assessment electrical quantity of motor, such as voltage
Survey.If reaching default magnitude of voltage, then zero position to be distributed to the position of active cylinder piston 18.In this zero position, logical
Gas piston 20 overcomes the effect of compression spring 16 to shift, and passage 5.8 forms the passage between moist chamber A and pressure chamber A1.
Meanwhile, ventilation orifice 5.11 is cut-off.
In order to the energy storage device that reclines active cylinder piston 18 carries out credible test, active cylinder piston 18 is as in fig. 11
Illustrating overcomes the effect of energy storage device 14 to move, until energy storage device 14 reaches backstop or blocking position like that further.
If the voltage of electrical quantity, such as motor exceedes preset value, then the position regulated is considered reference position.In this ginseng
Examining in position, vent piston maximally shifts, and moist chamber A and pressure chamber A.1 between the exchange of pressure medium can be with
The mode similar with in zero position is carried out.
Figure 12 illustrates the profile being in the hydrostatic actuator 1 loaded in position, and described hydrostatic actuator has wet
Room A, A.1, dry chamber B, hydrostatic pressure system 1.1 and the driver realized by means of motor 26 and planetary roller actuating device 15.
