DCR
Description of the safety valve:
To prevent the crimper from closing automatically (resulting in injury) when
attaching the air coupling, the valve cannot lock into place without air coupling.
The safety valve of the DCR crimper consists of the following main components:
housing no. 47, tappet no. 61, locking pin no. 63, lever no. 64, switch lever no. 505,
catch lever no. 65 and spring pin no. 66.
When the crimper is in idle position (not connected to the compressed air network), the
valve tappet 61 cannot lock into place. The catch lever 65 blocks the locking pin to
prevent it from catching. The spring pin of the lever 64 is then exactly vertical.
See Figure 1 and 2.
During connection to the compressed air network (application of the quick-
release coupling), the catch lever no. 65 is actuated and releases the stop
lever no. 64 with the locking pin no. 63.
See Figure 3 and 4.
