The PKL is a pneumatic "hammer". Compressed air goes under the pis-
ton (4) and presses it against one or two springs (3).
When exhausting, the air chamber beneath the piston empties abruptly via
the quick air-exhaust valve (1).
The piston (4) (hammer) is struck by the spring force against an impact
plate (6), which then passes the impact force (F) on. For PKL without an
impact plate (PKL 190, PKL 450 and PKL 740), the piston strikes directly
against the fastening surface. The PKL 1000, PKL 2100, PKL 5000 and
PKL 10000 have an impact plate.
The air escapes via the silencer (2).
The PKL only work when mounted, as the piston chamber is then sealed
by a built-in O-ring in the mounting surface (until PKL 740) or by a damper
ring (flange; from PKL 1000 on).
A quick-air exhaust valve and a 3/2-way valve are integrated in the valve
head of the PKL 740. Therefore, the control valve on the customer's site
can be mounted at any distance away from the PKL 740.
The control air must be connected at the side. A silencer is mounted on
the exhaust air outlet.
The ST kit allows a continuous impact sequence with permanent com-
pressed air supply.
The EE kit generates a "rubber hammer effect" and reduces the noise lev-
el.
