Description

Actuation or drive system,

Invention shall look to hydraulic or pneumatic drive systems or Bctätigungs- _e

More particularly, the invention relates to actuating or drive systems which have a mechanical lock or a mechanical lock for locking a piston of the system in one or the other of its rest positions ₀

It is an object of the invention to ensure, that the Lock is moved into its release position before the main piston from its rest position, in which the lock was applied, to its other rest position

According to the invention, a drive or actuation system is provided in which, mechanical interlocks or mechanical locks "are provided to a piston of the actuation or drive system in one of its to be locked in both rest positions, \ 70 in the case of mechanical Lock or lock is arranged and designed in such a way that it automatically moves into the locking or locked position when the The piston is moved into said one position and the pressure signal of a fluxing medium, which aur used movement of the piston in its other rest position is exploited in such a way that this is the solution or Unlocking of the never mechanical lock or locking causes the piston to move before this signal evokes. "

According to a further feature of the invention, a driveB- or actuation system is provided which has a main piston device, mechanical devices for locking or locking the piston of the main piston unit in one of its two rest positions. gen and a second piston unit, which is connected to the lock or lock in order to actuate it.

gen, wherein the piston moves this second piston unit v / irö to lock the locking device or to effect the lock in the event of a pressure signal, the triggering of which is controlled by a first valve or slide is which is controlled by the main piston unit when said one rest position is reached and wherein the piston of the second piston unit is moved to jäxfcriegelung the lock or the locking device by means of a further pressure signal which is then used to move the piston of the first To move the piston unit into its other rest position with the interposition of a further slide, v / which is opened by the second piston after the lock or lock is released. Preferably the first slide has a passage on the piston of the main piston unit which is arranged in this way and it is arranged that, when the piston of the main piston unit is in said one position, this passage is connected to passage openings, which are present in a pressure line leading to the

Cylinder of the second piston unit leads, whereby the Connection to the cylinder is established.

The further slide can have a passage on the piston of the second piston unit, which is arranged in this way

Based on the drawing, which schematically shows a pneumatic shows actuated drive system which has a pneumatically actuated mechanical lock or interlock, the invention should be explained again "

The actuation or drive system has a main piston rod 1, which is connected to a piston 2 at one end. This "piston 2 is inside a cylinder 5 movably arranged. The piston 2 is relative to the cylinder 3 by means of high pressure -—- air moves. This compressed air is fed to one or the other of the sides 2A and 2B of the piston «

The piston rod 1 is via a pivotable member 4 with a mechanical Verrie'gelungs- or locking device connected »This mechanical locking or blocking device has a locking bar 5, the inner

The locking or locking element 7 of the locking device is through a locking roller or locking bar is formed »the locking element 7 is connected via a toggle lever or crank part 8 to one end of a piston rod 9, the other The end is connected to a piston 10. This piston is slidably supported in a further cylinder 11. the Piston rod 9 is opposite to cylinder 10 by the introduction of compressed air under high pressure one side 10i. or 10B of the piston 10 'is moved.

The high pressure compressed air is fed to the respective sides of pistons 2 and 10 controlled by means of a selection or control slide. This control slide has a slide part 12, which has two fields 13 and 14. This slide assembly is slidably mounted within a valve housing 15. The unfortunately 13 and H subdivide the housing 15 in three separate sections 16, 17 and The high pressure compressed air is dem.Interraum of the housing via a suitable feed line 19, which is connected to a Durohgang opening 20 in the housing wall is in connection.

For purposes of illustration, assume doJ3 at the beginning the locking or blocking device ssieh, as shown in the drawing, in their unlocked Position. Furthermore there is the piston 2, as shown, in its retracted position and the piston rod 9 in its extended position. Additionally it is assumed that the control or selection slide is in the position shown in the drawing «In this position of the slide 12 i.-ird the high pressure compressed air from the line 19 via the opening 20, the section 17, the opening 21 in the housing 15> the line 22 and an opening 23 dem Interior of the housing 11 supplied so that this compressed air exerts a pressure on the piston side 1OB to the To hold piston 10 in the position shown in the drawing.
