Abstract

The invention relates to piston device (1) for a valve device (30), said piston device (1) comprising: a piston (2) and a nut (3), said piston (2) comprising a piston head (4), a piston rod (5) extending from the piston head (4) in an insertion direction (ID) to a piston front end (6), an external thread (8), a first abutment face for stopping an insertion movement in said insertion direction (ID), and a first locking means, said nut (3) comprising an internal thread (12), a second abutment face for contacting the first abutment face, and a second locking means for interlocking with said first locking means (10), wherein in an inserted position said external thread (8) being screwed into said internal thread (12) in a first rotation direction (R1), and said first abutment face and said second abutment face contacting each other thereby defining the relative position of the piston (2) in said nut (3), and wherein in said inserted position said first locking means (10) being interlocked or blocked with said second locking means, thereby preventing a relative rotation of said piston (2) in a second rotation direction (R2) that is reverse to said first rotation direction (R1).
