An anti-rotation projection engages the seal body and extends from the seal body into the pocket recess of the first machine component.

The anti-rotator prevents rotation of the anti-rotation retainer relative to a longitudinal axis of the anti-rotation retainer when the anti-rotation retainer is disposed in the valve.

Turning motion is carried out with an anti-rotation pin (110) inscribing in an anti-rotation bearing (guide mechanism) (111).

An example anti-rotation assembly includes an anti-rotation retainer to couple to a flow control member of a valve and an anti-rotator to engage the anti-rotation retainer.

without the anti-rotation device in use.

with the anti-rotation device in use; and

An anti-rotation device prevents rotation, but allows orbital translation of drum.

The screw (2) is an anti-rotation screw.

The flexible hose assembly also has a second coupling member (14) with a second anti -rotational element (28) on a first end (22), the second anti-rotational element being configured to mate with the first anti-rotational element.

The rotation prevention sections (3d) each have a recess (3e) formed at substantially the center in the width direction of the rotation prevention section (3d) and open on the front end side of the rotation prevention section (3d).

The preferred anti-spin system is adapted to control rotation of the crushing head.

It is proposed that at least one rotation-locking element (19) which can interact with a rotation-locking element (19) of the machine neck be arranged in a fixed position on the clamping ring (7) for forming the anti-rotation locking means.

The anti-rotation device (20) comprises a floor (25).

A container with an anti-loss and anti-idle-rotation cap is disclosed.

The anti-rotation screw comprises a screw body.
