The main piston of such active cylinder for hydraulic pressure, as proposed in this in such manner, it is possible to be made especially shortly, and
And allow point-device displacement measurement simultaneously in the case of simple regulation.Herein propose a kind of piston body, the piston body
Undertake the mechanical function of main piston.Two dynamic axial seal rings, the axial seal are set for the motion of main piston
Ring is sealed to the gap between piston body and active cylinder and especially makes primary pressure room and the second pressure of active cylinder
Room is separated from each other in the axial direction.Here, according to the position of main piston, the first dynamic axial seal ring or the second dynamic axle
Sealed to sealing ring.Not only the first dynamic axial seal ring but also the second dynamic axial seal ring can be configured to axle
To sealing ring, the axial seal ring can in the axial direction be positioned via target device.
According to another aspect of the present invention, a kind of active cylinder of the hydraulic pressure of clutch for hydraulic operation, institute are proposed
Stating active cylinder has according to the main piston of foregoing description, the pressure cylinder with primary pressure room and the position for determining main piston
Induction coil.
The active cylinder of hydraulic pressure is for example designed to hydraulically operated clutch.This is hydraulically engaged or divided via active cylinder
From slave cylinder.In the active cylinder of hydraulic pressure, pressure cylinder surrounds the main piston according to foregoing description.Such pressure cylinder has primary
Balancing gate pit and second pressure room, wherein target device can be arranged in primary pressure room.In order to determine main piston in pressure cylinder
In position be provided with induction coil, the induction coil is preferably provided at the outside of pressure cylinder.Thus target device is in the line of induction
Moved in the induction field of circle.The active cylinder of such hydraulic pressure can be constituted while providing the position to main piston very shortly
Point-device measurement.
According to another advantageous embodiment of the active cylinder of hydraulic pressure, target device be arranged in primary pressure room and
Separatedly set with the inwall of primary pressure room.
Because target device be not provided be used for seal, and pressure cylinder primary pressure room relative to second pressure room in footpath
Widen upwards, so the target device and the target device of prior art differently can be also arranged in primary pressure room.
The sealing for causing the inwall relative to primary pressure room by target device is unnecessary in this configuration.More properly
Say, target device can be matched with the size of second pressure room in terms of its radial expansion, that is to say, that with primary pressure room
The diameter of inwall is compared and may be significantly smaller.Meanwhile, very thin target device can around piston body due to mechanical reason or
Reasons in structure and necessary diameter are set, and need not be supplemented in the axial direction.
